part 3: down the NodeRed rabbit hole - resurrection (long)
so, now that i've got about 4 weeks of NR experience under my belt, i thought i would do a follow up and show a few new flows. plus, i've picked up a few new hardware add-ons. namely a Harmony Hub and a coupla Sonoff/Tasmota S31. one of the new things i did was setup some global.variables i can use in any flow. https://imgur.com/YFJEwRd 1] is pretty obvious, does my bayesian sensors think i'm home/not_home, and then save it to a global.variable. 2] reads the MQTT for my S31 power monitor on my dumb TV. if it's > 100, then the TV is ON, <= 99, then TV is OFF (or in the process of turning off). then set a global.variable for on/off. https://imgur.com/mcuS1Vk 3] i changed the day/night temperatures to global.variables. 4] this one gets the current volume level of my Sonos and then stores that to a global.variable. (get to why further below) 5] this one i talked about in another post here: https://www.reddit.com/homeassistant/comments/abvqup/device_tracker_with_unifi2mqtt/ okay, so now that i know if my dumb TV is on/off, then i can add it into my "away" (and "bedtime") flow. that gray one on the bottom right is using the HarmonyHub control node to fire the power toggle. (which i'll get to further below) plus it'll stop my Sonos, if it's playing. https://imgur.com/nerbMv3 also you may notice the "alexa TTS" one, that's a subflow, which is a bit of reusable flow, you can put anywhere you want it. this one picks a random number between 1 and 10, then alexa TTS plays the corresponding message. https://imgur.com/bLtBlaD this was also my attempt to get alexa to say "aaaf-firmative" like newt in aliens. https://imgur.com/cUnG1IE doesn't really work, but i'm determined to make this happen. gonna have to figure out the proper phonetics of it. then i'm totally gonna get her to do a stutter like max headroom on one of the other responses. but, my ultimate goal is to get her to do "twiki" from buck rogers. beaty beaty anyways, i've also added that subflow to all my switch on/offs. along with an MQTT log. https://imgur.com/SnpAnW8 now for some of the new stuff... here's a sleep timer. if i'm listening to music in bed, i can activate this with "alexa turn on sleep" and what it does, is it takes the current volume level of my Sonos, stored in a global.var, stores it in a flow.var, then subtracts 1 every minute, until it reaches zero. if the volume is at 30, then it'll be 30 mins until zero. https://imgur.com/7QmbY2S once it reaches zero, it stops the music, sets the volume back to the original state (ie: 30) and then turns itself off. there's an issue when you use something like a Harmony Hub to turn on/off dumb devices via input_bool, or switches, or lights, etc.: that once you turn it on via NR, HA, HHub, Alexa, etc., then HA thinks it's on. if you then turn it off via the device remote, HA won't let you turn it on again, because HA thinks its already on. so, i had to use a script and a "dummy" input_boolean. by dummy i mean, that i do not care, and will not EVER care, what it's state is. on. off. whatever. won't need it. it just needs to be there for the script to work.
input_boolean: mac_x: game_x: candles_x: tv_x:
hide them from emu_hue, cause Alexa doesn't need to see them either.
so instead of key'ing off the input_booleans, i key off the script call. "alexa, turn on candles" calls the script, which toggles the i_b but i only care about the state change of the script. then NR does it's thing. https://imgur.com/Hky9fWd notice tho, that it's a little smart. if the tv is already on, via that global.var, then it just switches inputs, otherwise it turns it on, waits 7 seconds, then switches inputs. okay, here's something REALLY advanced. i have a second pi running cgminer with a USB hub and some USB stick ASIC bitcoin miners. and every once and a while, they stop working and need to be reset. and you can't just restart, you gotta kill the power to the hubs to get them to reset. and then restart cgminer. enter NR cgminer node and the cgminer API. https://imgur.com/POSkjrp so every 5 mins, hit the cgminer API, it returns stats in json, dump those to mqtt. use the function node to pull out the array nested values we need to look at. look for a zero value in any of them. if the input_boolean "auto-reset-miner" is on, then lets reset. stop cgminer, wait, turn off the USB hub, wait, turn on hub, wait, start cgminer, send an alert to mqtt and SMS me. now the real magic is the red exec "start cgminer" node. because we stopped cgminer, we have to start it again, on a whole other computer than NR is on. it basically does a SSH into the miner pi and starts up cgminer. this was difficult to accomplish inside a docker of NR. i had to move some ssh keys around and then reference them with full paths. then i had to do an ssh-copy-id so it didn't require a password.
Crypto Mining for Beginners. Is it really worth it?
Image from blokt.com Mining cryptocoins is an arms race that rewards early adopters. You might have heard of Bitcoin, the first decentralized cryptocurrency that was released in early 2009. Similar digital currencies have crept into the worldwide market since then, including a spin-off from Bitcoin called Bitcoin Cash. You can get in on the cryptocurrency rush if you take the time to learn the basics properly.
Which Alt-Coins Should Be Mined?
Image from btcwarp.com If you had started mining Bitcoins back in 2009, you could have earned thousands of dollars by now. At the same time, there are plenty of ways you could have lost money, too. Bitcoins are not a good choice for beginning miners who work on a small scale. The current up-front investment and maintenance costs, not to mention the sheer mathematical difficulty of the process, just doesn't make it profitable for consumer-level hardware. Now, Bitcoin mining is reserved for large-scale operations only. Litecoins, Dogecoins, and Feathercoins, on the other hand, are three Scrypt-based cryptocurrencies that are the best cost-benefit for beginners. Dogecoins and Feathercoins would yield slightly less profit with the same mining hardware but are becoming more popular daily. Peercoins, too, can also be a reasonably decent return on your investment of time and energy. As more people join the cryptocoin rush, your choice could get more difficult to mine because more expensive hardware will be required to discover coins. You will be forced to either invest heavily if you want to stay mining that coin, or you will want to take your earnings and switch to an easier cryptocoin. Understanding the top 3 bitcoin mining methods is probably where you need to begin; this article focuses on mining "scrypt" coins. Also, be sure you are in a country where bitcoins and bitcoin mining is legal.
Is It Worth It to Mine Cryptocoins?
As a hobby venture, yes, cryptocoin mining can generate a small income of perhaps a dollar or two per day. In particular, the digital currencies mentioned above are very accessible for regular people to mine, and a person can recoup $1000 in hardware costs in about 18-24 months. As a second income, no, cryptocoin mining is not a reliable way to make substantial money for most people. The profit from mining cryptocoins only becomes significant when someone is willing to invest $3000-$5000 in up-front hardware costs, at which time you could potentially earn $50 per day or more.
Set Reosonable Expectations
If your objective is to earn substantial money as a second income, then you are better off purchasing cryptocoins with cash instead of mining them, and then tucking them away in the hopes that they will jump in value like gold or silver bullion. If your objective is to make a few digital bucks and spend them somehow, then you just might have a slow way to do that with mining. Smart miners need to keep electricity costs to under $0.11 per kilowatt-hour; mining with 4 GPU video cards can net you around $8.00 to $10.00 per day (depending upon the cryptocurrency you choose), or around $250-$300 per month. The two catches are: 1) The up-front investment in purchasing 4 ASIC processors or 4 AMD Radeon graphic processing units 2) The market value of cryptocoins Now, there is a small chance that your chosen digital currency will jump in value alongside Bitcoin at some point. Then, possibly, you could find yourself sitting on thousands of dollars in cryptocoins. The emphasis here is on "small chance," with small meaning "slightly better than winning the lottery." If you do decide to try cryptocoin mining, definitely do so as a hobby with a very small income return. Think of it as "gathering gold dust" instead of collecting actual gold nuggets. And always, always, do your research to avoid a scam currency.
How Cryptocoin Mining Works
Let's focus on mining scrypt coins, namely Litecoins, Dogecoins, or Feathercoins. The whole focus of mining is to accomplish three things: - Provide bookkeeping services to the coin network. Mining is essentially 24/7 computer accounting called "verifying transactions." - Get paid a small reward for your accounting services by receiving fractions of coins every couple of days. - Keep your personal costs down, including electricity and hardware.
The Laundry List: What You Will Need to Mine Cryptocoins
https://preview.redd.it/gx65tcz0ncg31.jpg?width=1280&format=pjpg&auto=webp&s=f99b79d0ff96fe7d529dc20d52964b46306fb070 You will need ten things to mine Litecoins, Dogecoins, and/or Feathercoins. 1) A free private database called a coin wallet. This is a password-protected container that stores your earnings and keeps a network-wide ledger of transactions. 2) A free mining software package, like this one from AMD, typically made up of cgminer and stratum. 3) A membership in an online mining pool, which is a community of miners who combine their computers to increase profitability and income stability. 4) Membership at an online currency exchange, where you can exchange your virtual coins for conventional cash, and vice versa. 5) A reliable full-time internet connection, ideally 2 megabits per second or faster speed. 6) A hardware setup location in your basement or other cool and air-conditioned space. 7) A desktop or custom-built computer designed for mining. Yes, you may use your current computer to start, but you won't be able to use the computer while the miner is running. A separate dedicated computer is ideal. Do not use a laptop, gaming console or handheld device to mine. These devices just are not effective enough to generate income. 8) An ATI graphics processing unit (GPU) or a specialized processing device called a mining ASIC chip. The cost will be anywhere from $90 used to $3000 new for each GPU or ASIC chip. The GPU or ASIC will be the workhorse of providing the accounting services and mining work. 10) A house fan to blow cool air across your mining computer. Mining generates substantial heat, and cooling the hardware is critical for your success. 11) You absolutely need a strong appetite of personal curiosity for reading and constant learning, as there are ongoing technology changes and new techniques for optimizing coin mining results. The most successful coin miners spend hours every week studying the best ways to adjust and improve their coin mining performance.

how to shibecoin v rich in minutes much instruct so simple any doge can do
UPDATE 1/21/14: I'm not updating this guide anymore. Most of the steps should still work though. See the wiki or check the sidebar for updated instructions. Before you do anything else, you need to get a wallet. Until there's a secure online wallet, this means you need to download the dogecoin client. Now open the client you just downloaded. You'll be given a default address automatically, and it should connect to peers and start downloading the dogechain (aka blockchain in formal speak). You'll know because there will be a progress bar at the bottom and at the lower right there should be a signal strength icon (TODO: add screenshots). If you've waited 2 or 3 minutes and nothing is happening, copy this:
And paste it into a new text file called dogecoin.conf, which you then place into the dogecoin app directory.
On Windows this is C:\Users\[YOUR_USER]\AppData\Roaming\DogeCoin
On Macs it's ~/Library/Application Support/DogeCoin
Now restart your qt client and the blockchain should start downloading in about 1-2 minutes. Once it finished downloading, you're ready to send and receive Dogecoins!
Decide how you want to get Dogecoin. Your options are:
I'll go into detail about each of these. I'm currently writing this out. I'll make edits as I add sections. Suggestions are welcome.
Mining is how new dogecoins are created. If you're new to crypto currencies, read this. To mine (also called "digging"), a computer with a decent GPU (graphics card) is recommended. You can also mine with your CPU, but it's not as efficient.
These instructions cover only Windows for now. To mine, you'll need to figure out what GPU you have. It'll be either AMD/ATI or Nvidia. The setup for both is approximately the same.
Step One: Choose a pool
There's a list of pools on the wiki. For now it doesn't really matter which one you choose. You can easily switch later. NOTE: Youcanmineintwoways.Solominingiswhereyouminebyyourself.Whenyoufindablockyougetallthereward.Poolminingiswhenyouteamupwithotherminerstoworkonthesameblocktogether.Thismakesitmorelikelythatyou'llfindablock,butyouwon'tgetallofit,you'llhavetosplititupwithothersaccordingtoyourshareofthework.Poolminingisrecommendedbecauseitgivesyoufrequentpayouts,becauseyoufindmoreblocks.Thelargerthepoolyoujoin,themorefrequentthepayouts,butthesmallertherewardyouget. Overalongperiodoftimethedifferencebetweenpoolandsolomininggoesaway,butifyousolomineitmightbemonthsbeforeyougetanycoins.
Step two: Set up pool account
The pool you chose should have a getting started page. Read it and follow the instructions. Instructions vary but the general idea is:
Create an account
Create a worker under the account
Grab the mining URL (usually on the getting started page)
Setup your cash out options in your account settings by entering one of your wallet's receiving addresses
When you're done with this, you'll need to know:
Your account, worker name, and worker password
The mining (stratum) URL (usually the pool's URL followed by a port)
Step three: Download mining software
For best performance you'll need the right mining software.
Create a text file in the same folder as your miner application. Inside, put the command you'll be running (remove brackets). For AMD it's cgminer.exe --scrypt -o stratum+tcp://: -u -p For Nvidia it's cudaminer.exe -o stratum+tcp://: -O : Substitute the right stuff in for the placeholders. Then on the next line of the text file type pause. This will let you see any errors that you get. Then save the file with any name you want, as long as the file extension is .bat. For example mine_serverName.bat.
Step five: Launch your miner
Just open the .bat file and a command line window should pop up, letting you know that the miner is starting. Once it starts, it should print out your hash rate. If you now go to the pool website, the dashboard should start showing your hashrate. At first it'll be lower than what it says in the miner, but that's because the dashboard is taking a 5 minute average. It'll catch up soon enough. NOTE: Anormalhashrateisbetween50Kh/suptoeven1Mh/sdependingonyourGPU.
You're now mining Dogecoins
That's it, nothing more to it.
CPU mining isn't really recommended, because you'll be spending a lot on more on power than you'd make from mining Dogecoin. You could better spend that money on buying Dogecoin by trading. But if you have free electricity and want to try it out, check out this informative forum post.
Trading has been difficult so far, but Dogecoin just got added to a few new exchanges. If you don't have a giant mining rig, this is probably the best way to get 100k or more dogecoins at the moment. I'll write up a more complete guide, but for now check out these sites:
Faucets are sites that give out free coins. Usually a site will give out somewhere between 1 and 100 Dogecoin. Every site has its own time limits, but usually you can only receive coins once every few hours, or in some cases, days. It's a great way to get started. All you do is copy your address from the receive section of your wallet and enter it on some faucet sites. Check out /dogecoinfaucets for more. If you go to each site on there you might end up with a couple hundred Dogecoin!
This method is pretty straightforward. Post your receiving address, and ask for some coins. Such poor shibe. The only catch is, don't do it here! Please go to /dogecoinbeg.
Other redditors can give you Dogecoin by summoning the tip bot, something like this: +dogetipbot 5 doge This might happen if you make a good post, or someone just wants to give out some coins. Once you receive a tip you have to accept it in a few days or else it'll get returned. Do this by following the instructions on the message you receive in your inbox. You reply to the bot with "+accept". Commands go in the message body. Once you do that, the bot will create a tipping address for you, and you can use the links in the message you receive to see your info, withdraw coins to your dogecoin-qt wallet, see your history, and a bunch of other stuff. As a bonus, so_doge_tip has a feature where you can get some Dogecoins to start with in exchange for how much karma you have. To do this, send the message "+redeem DOGE" to so_doge_tip. You'll need to create a tipping account if you don't have one. If you want to create a tipping account without ever being tipped first, message either of the bots with "+register" and an address will be created for you.

I am seeing too many new people come and and getting confused. Litecoin wiki isn't the greatest when it comes to summing up things so I will try to do things as best as I can. I will attempt to explain from what I have learned and answer some questions. Hopefully people smarter than me will also chime in. I will keep this post updated as much as I can. Preface Litecoin is a type to electronic currency. It is just like Bitcoin but it there are differences. Difference explained here. If you are starting to mine now chances are that you have missed the Bitcoin mining train. If you really want your time and processing power to not go to waste you should mine LTC because the access to BTC from there is much easier. Mining. What is it? Let's get this straight. When making any financial commitment to this be prepared to do it with "throw away" money. Mining is all about the hashrate and is measured in KH/s (KiloHash/sec). Unlike the powerful ASICs (Application Specific Integrated Circuit) that are used to mine bitcoins using hashrates in the GH/s and even TH/s, litecoin mining has only been able to achieve at the very best MH/s. I think the highest I've seen is 130 MH/s so far. Which leads us to our next section. Mining Hardware While CPU mining is still a thing it is not as powerful as GPU mining. Your laptop might be able to get 1 a month. However, I encourage you to consult this list first. List of hardware comparison You will find the highest of processors can maybe pull 100 KH/s and if we put this into a litecoin mining calculator it doesn't give us much. Another reason why you don't want to mine with your CPU is pretty simple. You are going to destroy it. So this leaves us with GPUs. Over the past few months (and years) the HD 7950 has been the favourite because it drains less power and has a pretty good hashrate. But recently the introduction of the R9 290 (not the x) has changed the game a bit. People are getting 850 KH/s - 900 KH/s with that card. It's crazy. Should I mine? Honestly given the current difficulty you can make a solid rig for about $1100 with a hashrate of 1700 KH/s which would give you your investment back in about a month and a half. I am sure people out there can create something for much cheaper. Here is a good example of a setup as suggested by dystopiats PCPartPicker part list / Price breakdown by merchant / Benchmarks
Prices include shipping, taxes, and discounts when available.
Generated by PCPartPicker 2013-11-29 00:52 EST-0500
Estimated Hashrate (with GPU overclocking) : 1900 KH/s Hardware Fundamentals CPU - Do you need a powerful CPU? No but make sure it is a decent one. AMD CPUs are cheap to buy right now with tons of power. Feel free to use a Sempron or Celeron depending on what Motherboard you go with. RAM - Try to get at least 4 GB so as to not run into any trouble. Memory is cheap these days. I am saying 4 GB only because of Windoze. If you are plan to run this on Linux you can even get away with less memory. HDD Any good ol 7200 RPM hard drive will do. Make sure it is appropriate. No point in buying a 1TB hard drive. Since, this is a newbie's guide I assumed most won't know how to run linux, but incase you do you can get a USB flash drive and run linux from it thus removing the need for hard drive all toghether. (thanks dystopiats) GPU - Consult the list of hardware of hardware I posted above. Make sure you consider the KH/s/W ratio. To me the 290 is the best option but you can skimp down to 7950 if you like. PSU - THIS IS BLOODY IMPORTANT. Most modern GPUs are power hungry so please make sure you are well within the limits of your power consumption. MOTHERBOARD - Ok, so a pretty popular board right now is Gigabyte GA-990FXA-UD3 and the ASRock 970 Extreme4. Some people are even going for Gigabyte GA-990FXA-UD5 and even the mighty Gigabyte GA-990FXA-UD7 because it has more PCI-E slots. 6 to be exact. However you may not need that much. With risers you can get more shoved into less. PCI-E RISERS - These are called risers. They come in x16 to x16 and x1 to x16 connections. Here is the general rule of thumb. This is very important. Always get a POWERED riser otherwise you will burn a hole in your MoBo. A powered rise as a molex connector so that additional power from PSU can be supplied. When it comes to hardware I've provided the most basic knowledge you need. Also, take a look at cryptobader's website. This is very helpful. Please visit the mining section of Litecoin Forums and the litecoinmining subreddit for more indepth info. Mining Software Now that you have assembled your hardware now you need to get into a pool. But before you do that you need a mining software. There are many different ones but the one that is most popular is cgminer. Download it and make sure you read the README. It is a very robust piece of software. Please read this if you want to know more. (thanks BalzOnYer4Head) Mining Pools Now that your hardware and software is ready. I know nothing about solo mining other than the fact that you have to be very lucky and respectable amount of hashing power to decrypt a block. So it is better to join pools. I have been pool hopping for a bit and really liked give-me-coin previously known to the community as give-me-ltc. They have a nice mobile app and 0% pool fees. This is really a personal preference. Take a look at this list and try some yourself. How do I connect to a pool? Most pools will give you a tutorial on how to but the basics are as follows:
Signup for a pool
Create a worker for your account. Usually one worker per rig (Yes people have multiple rigs) is generally a good idea.
Create a .run file. Open up notepad and type cgminer.exe -o (address_to_the_miningpool:port_number) -u (yourusername.workername) -p (your_worker_password_if_you_made_one). Then File>Save As>runcgminer.run (Make sure the drop down is set to "All Files" and .txt document.) and save in the same folder as cgminer. That's it.
Double click on runcgminer.run (or whatever you named it) and have fun mining.
Mining Profitability This game is not easy. If it was, practically everyone would be doing it. This is strictly a numbers game and there are calculations available that can help you determine your risk on your investments. 4 variables you need to consider when you are starting to mine: Hardware cost: The cost of your physical hardware to run this whole operation. Power: Measured in $/KwH is also known as the operating cost. Difficulty rate: To put it in layman's terms the increase in difficulty is inversely proportional to amount of coin you can mine. The harder the difficulty the harder it is to mine coin. Right now difficulty is rising at about 18% per 3 days. This can and will change since all you miners are soon going to jump on the band wagon. Your sanity: I am not going to tell you to keep calm and chive on because quiet frankly that is stupid. What I will tell you not to get too carried away. You will pull you hair out. Seriously. Next thing you will need is a simple tool. A mining profitability calculator. I have two favourite ones. coinwarz I like this one cause it is simple. The fields are self explanatory. Try it. bitcoinwisdom I like this one because it is a more real life scenario calculator and more complicated one (not really). It also takes increasing difficulty into account. Please note: This is the absolute basic info you need. If you have more questions feel free to ask and or google it! More Below.
Want to get started mining defcoin with an ASIC and a Raspberry Pi? Does 360 KH/s of mining power sound appealing? Here’s how to do it. https://pbs.twimg.com/media/Blpj8IvCcAEIStY.jpg 1) Hardware List -Raspberry Pi Model B --SD Card --Micro USB power supply --Ethernet cable -Gridseed ASIC --12V power supply (5.5mm/2.5mm barrel connector) --USB to Mini USB data cable The main component is the Gridseed ASIC, which will be doing the Scrypt calculations. The Raspberry Pi will be used as the controller for the ASIC, and will be doing the communication with the mining pool. If you’re not familiar with the term, an ASIC is an Application-Specific Integrated Circuit - basically a chip with a single purpose, like mining crypto currency. Using an ASIC will allow us to mine more efficiently than we would be able to with general purpose hardware. The ASIC that I’m using is a “300+ KH/s Single Gridseed ASIC Miner”. It looks like a CPU heatsink with a fan attached. There is actually a circuit board with 5 ASIC chips sandwiched between two halves of this heatsink, and has a mini USB connector and a power connector sticking out the side. There are a few places where you can buy these. I bought mine at GAWMiners.com for $130. That was the lowest price that I could find, and I had a good experience buying from them. Use this link, and you can get $20 off of a $200 order (and give me some referral points :-)) GAWMiners. You can also find other vendors by searching for “Gridseed ASIC”. You’ll need a 12V power supply to power the ASIC, and a USB A to USB Mini B cable to connect the ASIC to the Raspberry Pi. I’m using a 60W power supply, which seems to be working fine for defcoin (Scrypt) mining. These ASICs can also mine Bitcoin at the same time, but you may need a beefier power supply if you want to do that. The Raspberry Pi can be purchased at any number of places- Amazon, SparkFun, AdaFruit, etc. I’m using the Model B because I had one already, and also because it has a built in ethernet port that will make connecting to the internet easy. Make sure to get an SD Card and a micro USB power adapter to get the Pi up and running too. 2) Software If you haven’t already, download the defcoin wallet from defcoin.org. If you want to do pooled mining, create an account for one of the defcoin pools, such as redbaron.us or whichever other pool you want to mine. Once you’ve created a pool account, make sure to create a worker too (for MPOS pools, that will be under My Account > My Workers). The password for your worker does not have to be the same as the password for your pool account (and it probably shouldn’t be). Next, download the latest Raspbian image from raspberrypi.org/downloads/ and install the image to your SD card. Instructions for installing the image can be found here. If you are using the dd method on a Mac, make sure to use /dev/rdiskX instead of /dev/diskX - both will work, but rdiskX is much faster. Once you have the image installed, put the SD card in the Raspberry Pi, connect the Pi to your network, and connect the Pi to your micro USB power adapter to power it on. Next, SSH in to your Raspberry Pi with the default username and password pi/raspberry. I use nMap to find the IP address that has been assigned to my Pi. You can also use an HDMI display and a USB keyboard to log in instead of using SSH. After logging in for the first time, run through the wizard that comes up to configure your Raspberry Pi. The defaults are fine for most things, just make sure that you don’t skip the step to expand the filesystem to use the rest of your SD card. If you don’t expand the filesystem, there won’t be enough space for other software. Once you have Raspbian installed, and have gotten through all of the first login setup stuff (which will likely end with a reboot), log back in to the Raspberry Pi with the pi user. From the command line, run sudo apt-get update sudo apt-get dist-upgrade There are some stability issues with USB communication between the Raspberry Pi and the Gridseed ASIC. Enabling SLUB debugging seems to resolve this, at least well enough to prevent the Raspberry Pi from freezing every so often. Open the /boot/cmdline.txt file, and add the following text to the end of the line. Don’t add a new line, just add this to the end. You can use vi, nano, or whatever your favorite text editor is to do this.
Reboot the Raspberry Pi once you’ve added that flag to your /boot/cmdline.txt file.
sudo shutdown -r now
Log back in with the pi user once the Raspberry Pi is finished rebooting. The mining software that we’re going to use is a customized version of cgminer that has support for the Gridseed GC3355 chips that are used in our ASIC. There are a number of different mining programs out there, this is just what has been working the best for me so far. First, install git and dependencies needed to compile cgminer.
cd cgminer-gc3355 autoreconf -i ./configure --enable-scrypt --enable-gridseed make
Once the make command finishes, we’re ready to run the mining software. You can also run make install if you want to install the software, but running it out of the build directory works just fine. Plug in the power supply for your ASIC, and connect the ASIC to it. Connect the USB cable to the ASIC and to your Raspberry Pi. Run the mining software by running the following command. The -o option specifies your pool URL, the -u option specifies your username and the workername that you set up for the pool, and the -p option is the password for your worker. There are a couple of options available that are specific to the gridseed ASICs, and those will be placed after --gridseed-options. The freq=850 option sets the clock frequency of the ASIC to 850 MHz. There are other clock options available, but 850 seems to be working best for me. I was getting hardware errors at 900, and a lower average hash rate. I am getting about 360 KH/s with the clock frequency set to 850.
This command needs to be run with sudo in order to access the USB hardware. You can also create another user specifically for mining, or grant the pi user the appropriate permissions if you don’t want to run cgminer as root. When you run this command, you should see output from cgminer showing that it is communicating with the mining pool, and something showing your hash rate. If you’ve gotten this far, and you’re seeing output from cgminer showing a hash rate, congratulations, you’re mining defcoins with your ASIC! There are just a couple more steps to do if you want to let your Raspberry Pi and ASIC continue mining without needing you to be logged in. To keep cgminer running after I log out, I am using nohup. You could also use screen instead of nohup. Create a script (startMiner.sh) by running the following commands.
If you run this command with sudo startMiner.sh, cgminer will run in the background, and will continue running after you log out. If you want to have this run when your Raspberry Pi boots, modify your /etc/rc.local script so that it executes this startMiner.sh script. Your /etc/rc.local file will end up looking like this:
# Print the IP address _IP=$(hostname -I) || true if [ "$_IP" ]; then printf "My IP address is %s\n" "$_IP" fi /home/pi/startMiner.sh exit 0

[P2pool] How to make your own personal p2pool Node!
Tired of getting no block rewards and sending many dead shares? Need a p2pool node close to your miner? MAKE YOUR OWN! :D And, Yep, P2pools give 0.5% Rewards to block finders! Here's some info about p2ools: http://whatisp2pool.com/ The stronger the P2Pool network becomes the more resistant the digibyte network is to 51% attacks! Oh and, P2pools are DDOS proof! Now that's News! So if your node gets DDOS'd .. you dont lose your shares as the shares have been saved in the p2pool, its called the sharechain. So you get paid anyhow! Thanks to the p2pool network. and you ccan set your workers to another pool using the "--failover only" command in cgminer (if im not wrong) and get it back to work on the p2pool network! TL;DR; P2POOL = 1 Big fat network Decentrazlized pool! STEPS TO MAKE A P2POOL: Install Ubuntu server or Desktop if you want http://www.ubuntu.com/download/ or u can use a VPS (VirtualPrivateServer -- Link Below with coupon code) So Let's start off in the command line (Open Terminal.. and all you have to do is Cut, Copy Paste! ;) ) Start by updating and upgrading Ubuntu, you know you want the best ;)
git clone git://github.com/digibyte/DigiByteProject.git digibyte #renaming makes it easier ;) cd ~/digibyte/src mkdir obj make -f makefile.unix USE_UPNP=- sudo cp digibyted /usbin cd ~
After it has compiled try running 'digibyted'
If you get an error saying you need to make the digibyte.conf file, good! :) If it doesnt give you that error, make sure you followed the compiling steps appropriately. So, Lets create the conf file here...
cd .digibyte #edited from 'digibyted' .. fixed!! nano digibyte.conf
Paste the following, CHANGING THE USERNAME AND PASS!! make sure to take note of both, you'll need these later!
Press 'CTRL' + ' X', and then 'Y' to save when prompted
cd ~ ./digibyte/src/digibyted ./digibyte/src/digibyted getinfo
Make sure you check the latest block in the block chain or on your local DigiByte Wallets. This is to see how far your p2pool node has gotten! This is gonna take quite a while so lets CONTINUE! Let's get the p2pool software and frontend in! Install the p2pool dependencies!
Time to edit and customise the html code to personalise your p2pool's frontend. Feel free to change the p2pool name and if you're an advanced user, feel free to add your own frontend from git hub after removing the web-static folder. (OPTIONAL: by using rm -f -r web-static #in that directory. And then you can choose whichever frontend you want! by cloning it in the web-static folder) Editing the current frontend html!
cd .. cd web-static nano index.html
After personalising the page, i.e. changing the p2pool name and adding some info! Lets go back and check how far the block downloading has gotten! You can check this by typing this in the command line after going back to the root directory:
cd ~ ./digibyte/src/digibyted getinfo
This is gonna take a while so might as well check for updates again :P
sudo apt-get update sudo apt-get upgrade
After making sure that all the blocks have been synced locally! We're ready to run the p2pool node! Simply enter the string below in the command line, entering your USERNAME and PASS that you saved earlier!
If you want to charge a fee for your node add this to your string, adding your fee address!:
--fee 1.0 --address NEWDGBADDRESS
To see if the node is up and running enter this in the command line:
screen -x myp2pool
'CTRL' + 'A' + 'D' to close the terminal if you press 'CTRL' + 'C', it will terminate the p2pool program and you'll have to restart the pool by using the string above! Once, Everything is setup as planned! Check your p2pool node's ip Address by entering this into the command line:
inet addr: 192.168.1.1 #You'll see a line like this.
So, Your cgminer string should look something like this:
cgminer --scrypt -o 192.168.1.1:9022 -u DGBADDRESS -p x
And your p2pool WEB ADDRESS should look like this:
example: http://192.168.1.1:9022/ You can monitor your p2pool using that web address! Enjoy, your personal p2pool node!! :D If for whatever reason the server shuts off and you need to restart the p2pool node, you should run digibyted again and after it has synced successfully, just type in your p2pool string:
These are just a couple of the discoveries I've made in my first couple days of mining. Most of these will be things that are likely obvious to experienced miners, but can cause some confusion for new shibes like myself. So maybe someone else will be able to benefit from my mistakes.
Bitcoin (and several others) uses SHA-256 for its hashing algorithm. Dogecoin (and some others, most notably Litecoin) uses scrypt. The two are not compatible and, in fact, there is a huge discrepency in the hashes/second rates. For instance, my Radeon HD 4850 card runs at about 70 Mh/s for SHA-256, but only 100 Kh/s (0.1 Mh/s) for scrypt. I've gathered that this has something to do with scrypt requiring more computations per hash. When looking at Kh/s or Mh/s numbers, it is very important to know which algorithm is being used, otherwise this can lead to some confusion, for instance, when comparing thesesheets.
GUIMiner does NOT support scrypt (There is a separate program called GUIMiner-scrypt for that). However, GUIMiner will let you connect to a Dogecoin pool and even report acceptedshares all while running on the SHA-256 algorithm, which is useless for Dogecoins. I'm still not sure exactly why this happens, but it led to me wasting about a day of running my GPU with nothing to show for it, since I was convinced that if shares were being accepted, it must actually be doing something right.
cgminer can take a LOT of work to set up. First of all, there are several versions of cgminer, each with its own quirks, some with windows binaries available, and some you have to build yourself. Also, GPU mining is not supported past version 3.7.2. It took me a while and several failures at building/setting up different versions before I noticed the link on the right side of /dogemining that goes directly to a windows binary of cgminer 3.7.2. Much easier. I've heard that many consider cgminer to be superior to GUIMiner-scrypt, but since I can't get GUIMiner-scrypt to run, I can't say for myself.
Much of mining seems to be trial and error: finding the software and configuration that works for your specific setup. Every card will behave differently, and even though there's tons of information out there to help, it really just comes down to trying a bunch of things and finding out what works.
I'm happy to say I've just seen my first hundred Doge from mining, and I'm excited to see how far I can go (to the moon?). I'm sure I'm still mistaken about lots of things, and if I missed anything here, let me know.
Sup fellow reddit members! Today I'm here to give you guys a long introduction about bitcoins. Intro to bitcoins: Bitcoins are the first decentralized digital currency. Bitcoins are basically digital coins that you can send through the internet. Some advantages of bitcoins:
It can be transfered through other people without a bank having involved in the transaction.
The transaction fees are much lower.
You can use them in any and every country.
Your account (explained later) can never be frozen.
How it works: There are several online bitcoin currency exchange where you can exchange bitcoins for money and vice versa. Bitcoins are kept in a digital wallet on your computemobile device. coinbase.com is one of the most trustworthy online bitcoin wallet, IMO. Sending bitcoins is as simple as sending an email, and you can purchase ANYTHING with bitcoins as long as they accept the currency. The bitcoin software is completely open-sourced, so anyone can review the code. Bitcoins are easy + free to setup, and there are no chargebacks! How to obtain bitcoins: There are two ways to obtain bitcoins:
Mining them using applications. Miners solve math problems/bitcoin algorithms (which takes computing power) and are rewarded bitcoins for doing that. This is the one that I'm going to focus on, as it is pretty hard to grasp.
Mining bitcoins: Using special software application, you are able to mine bitcoins. Mining means to solve math problems/bitcoin algorithms using your computing power. Blocks are a chunk of 25 bitcoins, and if you solve one math problem you automatically get a block. The speed of mining bitcoins is measured in Hashes/Second (KH/s, MH/s, GH/s, TH/s etc.) The difficulty of the problems gradually increases as more bitcoins are found. Now, it is almost impossible to find bitcoin blocks by yourself, as more than 10 million bitcoins have been mined. Using special hardware (ASIC, Application-Specific Integrated Circuit chips) that specifically is aimed to mine bitcoins increases your mining speed by a lot. You can buy these hardware anywhere online/offline. amazon.com has many ASIC hardware on sale. But even ASIC mining can still take a long time to find a block by yourself. That's how the pooled mining began. Pooled mining basically combines the work of many miners toward a common goal. Pool of miners find the solution of the math problems faster than individuals, and they share the block equally based on each miner's hash rate. There are many pools right now that are pretty trustworthy, but that one that I use is triple mining: http://evilbeans124.triplemining.com Mining bitcoins on a Mac: This part is only dedicated on mining bitcoins for Mac users. If you're a PC user or a Linux/Ubuntu user, skip this.
Go to asteroidapp.com and download the latest version of Asteroid
Under the workers tab, add a new worker (on the right side)
Go back to GUI miner, enter in your worker username/password
If you have any hardware, then select them in the device tab. If not, skip this step
Mining bitcoins on a Ubuntu/Linux: This part is only dedicated on mining bitcoins for Linux/Ubuntu users. If you're a Mac or PC user, view above. Unfortunately, I have no experience in how to install any miner on Linux. The following website does however, so just follow it http://www.distrogeeks.com/install-cgminer-3-7-2-ubuntu/ The end I think I covered most of the points on bitcoins. However, if there is any mistakes/stuff that I should add, please put a comment below or PM me! It will be greatly valued! I spent sometime doing this, so some donation will be very appreciated.

I have looked over google for some help but im obviously not looking in the correct places because I did not see what i need. Hopefully someone here can point me in the right direction. Here is whats going on. I started off with 1 asic block erupter (ASICMiner Block Erupter USB 330MH/s Sapphire Miner) and everything was going fine. i added another one to the setup and everything was still going fine. (this is all being done on USB ports that are on the back of my PC, no USB hub, yet) I then aquired an antminer (BITMAIN ANTMINER U2 2Gh/s USB Bitcoin ASIC Miner. Overclockable) and plugged it into my PC as well. I am using BFGminer 3.10.0 currently and everything was running fine. all 3 miners were mining. I went ahead and ordered a usb hub because i figured if i was going to keep adding miners that my computer would not be a good place to put them all. well a day before the hub got here, i noticed that one of the miners (the saphire one) was not mining. i looked at my device manager and only saw 2 of them. so i rebooted, messed around with some different ports but nothing made that one work. i figured it was broken for whatever reason and assumed it was because it wasnt suppose to be on my mother board. thing is, it works on another PC. so i waited for the hub to come in to see if it would work on there but it still does not. Im thinking its a driver issue since its not showing up on this computer but it will on another. Any idea or suggestion on how to get my current PC (windows 8.0) to run it? Should i try a different version of bfgminer, or maybe cgminer? im fairly new to all this so i dont really know where to go with it.
Help with getting things to start mining scrypt currencies (using raspberry pi 2 , gridseed asic miner , & cgminer) . . .
Here's what I have & will be using (I already have the cables & power) : raspberry pi 2 Gridseed ASIC Miner for Litecoin and Bitcoin Mining --- 4 of these cgminer [ I followed this example for setting things up : https://www.reddit.com/defcoin/comments/23nvs1/raspberry_pi_asic_defcoin_mining_guide/ it is my understanding that any altcoin you wish to setup mining for , is done in this similar fashion ] I want to do scrypt cryptocurrency mining , I just want to understand how this is done .... ( I know there's a lot of tutorials out there & great vids , and I've done a lot of reading on all this matter , but I can't seem to get things working right , please help / advise ) Questions:
if I solo mine , what is the correct port # to use here (and is the below command formatted correctly more-or-less) :
sudo ./cgminer -o stratum+tcp:localhost:#### -u Username.Workername -p yourworkerpassword --gridseed-options freq=850 ( I understand I need to create my own pool , a pool of 1 , is considered to be solo-mining , correct ? How do I do this ? )
also , before I can solo-mine , I need to have downloaded & install the wallet for the cryptocurrency I am going to mine , correct ? And I understand there is some kind of Config files relevant that I should modify accordingly to set things up with my mining solo , right ? How is it done & where do I find this config files ??
I tried connecting my 4 gridseed(s) to my raspberry pi 2 , via the 4 usb ports it has , but it seems like it can't handle the 4 of them , so I have to deal with only using 2 of the gridseed(s) connected to my raspberry pi 2 at a time .... does this seem right to you ? And so , what work around do I have for this poroblem , I want to use all 4 of these gridseeds connected to my raspberry pi 2 ,,, I'm guess a usb hub is needed for this right ?
Setting up solo mining just targeting USB erupters? PC/Mac?
I am having trouble trying to get solo mining started on either my PC or Mac. I have a PC set up that is using three 7950s that are mining Litecoins. I'd like to have my 2 USB erupters solo mining Bitcoins for fun on the same system. I have the drivers installed for the USB miners and my system recognizes them. I am starting Bitcoin-QT as -server My bitcoin.conf looks like this: listen=1 server=1 rpcuser=user rpcpassword=pass I set up a BFG .bat like this: bfgminer.exe -o 127.0.0.1:8332 -O -u user -p pass When I launch that, BFG just crashes. I have also tried it with CGminer and that crashes also. I'd like to keep CGminer on the cards Litecoin mining and use BFG for the USB miners. How do I get BFG to work just with the USBs? Also, do I need to input a Bitcoin address somewhere so if I did solve something I get the payout? Sometimes, I do more work on my Mac and am also trying to set up the USBs to mine on a Mac using Diablo miner. Will that work the same way as the PC setup once we get it figured out? Thanks for any help.
So I've recently gotten into mining via PTS but I've quickly become addicted to it, now owning a 4 GPU full time mining rig. :P I have linux mint 16 running on it currently (my linux distro of choice) and drivers, overclocks, and the clpts miner have been working flawlessly. I'm not going to mine PTS forever though so getting cgminer for scrypt (and keccack) is a must. That's where I'm running into issues. I have done tons of research and have yet to come across an answer. I'm using cgminer 3.7.2. First and foremost I see is to extract the file and then cd into the directory and use ./cgminer -n to see if it detecs the GPUs. When I do that I get back... ./cgminer: -n: unrecognized option Okay, so that's a no go. How about I follow the install readme and compile it like instructed? So i run ./configure which does it's thing then prints out only a few lines of information. The last is as follows OpenCL................:Detection overrided. GPU minning support DISABLED configure: error: No mining in Now somebody else suggested maybe that I didn't have OpenCL setup correctly. This doesn't sound correct becuase whenever I run the clpts miner, one of hte first things it references is that it's pulling something from OpenCL. I also followed this guide... https://coinaxis.com/index.php/news/entry/how-to-configure-linux-and-build-cgminer-for-bitcoin-and-litecoin When I got to the compile part, I typed in everything as noted except my SDK was in a folder name AMD-APP so I changed it accordingly. Again I get the same message about GPU mining support DISABLED. Any suggestions? I'll tip you a PTS if you can help me figure this out.
Seeing how this Subreddit is lacking any sort of info on Feathercoins and the lack of community support we have, I have decided to start a post that would inform newbies about Feathercoin and seasoned vets on the best places to trade. Feathercoin: It is a Crypto Currency that was started by Peter Bushnell. It is a clone of Litecoin (This coin was inspired by Bitcoin). The Feathercoin network generates coins at a decreasing rate. It will generate about 336 million coins which is 16 times more than that of Bitcoin and 4 times more than that of Litecoin. Currently about 25 million coins have been generated. Network hashrates, Pools, Solo mining: Currently a mid end system comprising of 7870 or 7970 will get you abot 400 to 700 kh/s. That means that in a given day you will be mining about 7 to 13 Feathercoins on current difficulty level. However If you mine alone that is solo mining, the probability of you finding a block is hard and it may take a while before you make a coin. To counter this people have started making pools to increase the chances of finding blocks. There are many pools that allow you to have multiple workers so you can setup multiple systems and mine at your leisure. Currently some of the popular pools are: http://www.fcpool.com/ http://give-me-coins.com/ http://www.wemineftc.com/ http://fc.ltcoin.net/ https://ftc.d2.cc/ For a full list of mining pools: http://coinpools.sdfg.org/ftc It is highly recommended to join a pool to make mining profitable. Look at the pools posted above, look at their fee structure, their payout and make an informed decision on which pool to join. Hardware and Mining: Feathercoin utilizes scrypt based mining that is you can use your GPU (the Graphics card inside your system) to mine them. AMD Cards are highly recommended as they output higher hashrates as compared to Nvidia. To give you an idea of the difference a 7870 ghz edition mines at about 375 kh/s whereas a Nvidia 780ti would mine at about 224 to 300 kh/s. If you are seriously considering in investing in this venture it would be best to buy a rig that supports 6 GPU's and buy either the 7950 or the 280x as they have considerably higher hash rates and are affordable to say the least. Something one should be aware of is that mining produces a lot of heat as your system is basically running at full capacity and therefore needs a lot of cooling. People usually build rigs in the open (no case) and use household fans to cool them. Also another thing that is common is to use PCIe risers as they allow greater spacing between GPU cards and effectively help in dissipating heat. Mining uses a lot of electricity so it is best to use a schedule to mine or if electricity is cheap then 6 7950's running 24 hours a day would cost you about 12 to 18 dollars in electricity a month, maybe more depending on where you live. The software to use for mining are Cgminer (https://litecointalk.org/index.php?topic=6925.0), guiminer scrypt (http://forum.feathercoin.com/index.php?topic=961.0) and cudaminer for Nvidia cards. I would advise against Cpu mining as that is not profitable and will simply weigh you down. Invest 250 to 350 dollars in a good AMD GPU and you will be mining much more effectively. Trading: There are many places where one can trade Feathercoins but only a few of them offer FTC/USD exchange. Btc-e (https://btc-e.com/exchange/ftc_btc). Is one of the biggest cryptocoin trading exchanges, it does not offer USD exchange for Feathercoins as of yet but allows you to exchange for Bitcoins. Crypto-trade (https://www.crypto-trade.com/trade/ftc_btc), this trading exchange allows you to trade against the USD making it more favourable to miners however there is currently a lack of volume for FTC as of writing. Other exchanges like Cryptsy, Bter and coins-e are all good but they are heavily dependent on Bitcoins and Litecoins for now. My thoughts Feathercoin is fairly new and its gaining momentum, once big exchanges start listing it against the USD, the venture will become more profitable. For now it is advisable to mine as many as you can and sit on them till value improves or if you have a mining rig that is mining at 22000 kh/s (this will get you about 500 feathercoins a day) then mine the shit out of them and trade them for Btc for profit although I would recommend against this as it it reduces the value of feathercoin. Many exchanges allow you to deposit money via international wire transfers however the minimum is 2000 dollars so keep that in mind before investing real money into this venture. There are alternatives like paypal and okpay that are also accepted but not a lot of people have accounts on those so signup for a website that suits your situation. One last ting we all need to do is spread awareness about Feathercoin, It is a miners coin and the difficulty right now makes it so much more interesting to mine. I will update this page with more information and will answer questions if any to the best of my knowledge. Happy mining My FTC wallet deposit thingy address : 6v1VuL41xGuLG1Bd8usJsuUEkZyac8jKbe EDIT : I realized some of you might have NVIDIA GPU's and are hesitant on getting AMD. Never fear for there is a solution. If you have a motherboard that supports two or more GPU's that is you have more than one PCIe slots than follow these instructions: If you intend to game on your system while you are mining then put the NVIDIA card in PCI slot one and buy an AMD card and put it in slot 2. Now install the drivers in the order Nvidia first reboot and then Amd second reboot. You do not need to plug in HDMI to your AMD card just leave it as it is. Now download gpu miner scrypt and select from the list your AMD card and start mining, its that easy. At night if you want to squeeze in more kh/s then run cudaminer and let it mine alongside your AMD. The best part about this is that you can be mining 24/7 on your AMD card and you will not experience any system slow down while gaming or watching movies. Remember to have atleast two workers workers created so you can mine parallel. If you already have an NVIDIA card then just install your AMD card and install AMD drivers and reboot and run guiminer scrypt. At times you might run into the issue of guiminer not starting, just delete it and re install it and it should work fine in 98% of the cases. This is for those who do not want to invest in a completely new system and would rather use their existing system. You can use cgminer as well but remember the order in cgminer starts from 0 not 1 so if NVIDIA is in slot 1 then it is -d0 -g0 and AMD will be -d1 -g1
[modpost] Possible wiki page, something I call "All about miners," covering things from basic terminology to miner config files and overclocking.
What is a miner? A miner is a computer set up to solve cryptographic hashes in the litecoin network. Once a clump of these hashes, or a block, is mined, litecoins pop out! It's like opening a box of chocolates, except you know what you're gonna get :) Miners also handle transaction confirmations, making sure no single coin is double-spent. Setting up your computer to be a miner What kind of computer do I need? Optimally, you'd have a good power supply and a couple decent Radeon/ATI/AMD graphics cards. Because of litecoin's hash algorithm, the gap between mining with graphics cards and processors is less than with most other cryptocurrencies, meaning that mining with some desktop processors may be worth it after electricity costs. Note that mining with laptops is not recommended because of the heat generated by mining, and mining with NVIDIA graphics cards may not be worth the cost. How do I know if litecoin mining will be profitable for me? First, check how fast you'll be mining with your hardware, how many litecoins you'll mine in a day, and how much litecoins are worth. Now, multiply the number of litecoins per day by their worth. Then, find out the power draw of your hardware, and calculate energy cost. Then finish by subtract energy cost from your daily earnings. If your number is positive, you're making that much money per day. If negative, you're losing money. Keep in mind that the worth of litecoins goes up/down, and you have to earn the cost of your hardware before you churn a profit. Mining difficulty also goes up/down, depending on how many people are mining how fast in relation to how many litecoins are supposed to be generated how fast. See the economics(coming soon) post for more info. Okay, I did all that. How do I start? All you have to do is download a program and change some settings (later in the guide), and you're ready to go. If you're comfortable with configurations and the command line, Reaper and cgminer are your best friends. Otherwise, GUIMiner-scrypt is right for you. If you want to mine on your processor, download the "batteries included" miner via this link and setup should be relatively self-explanatory. Do I mine alone? Due to the difficulty of mining, we recommend that you mine with a pool where multiple people mine together. Visit your pool's about or help page for proper miner settings, which we're about to get to in-depth! Under the hood Configuring your miner (aka the hard part) Before we get started, you should become familiar with these terms:
host: Your pools website
port: The internet port your computer uses to connect to your pool
worker: Anything that mines is a worker. Just a way for you and your pool to keep track of what's mining how.
user: In mining programs, the user is the name of your worker, which by default tends to be poolusername.1 or poolusername_1, _2, etc.
pass: Password for your worker, NOT your pool password. This can usually be anything.
None of those will have any affect on how fast you mine. The settings that we'll be focusing on are:
worksize: Exactly what it sounds like
thread-concurrency: Setting that involves computations happening simultaneously
vectors: Involves how memory is used
aggression/intensity: How aggressively your computer mines
threads_per_gpu: How many threads of data to process on a GPU, like threads of a CPU. Anything beyond 1 usually doesn't increase hashrate on modern cards.
device: First GPU is device 0, second is device 1, etc.
If you're using GUIMiner-scrypt, there are default settings for different cards (lower right dropdown). I'm mining on a 7870. Here is what it looks like for me. You can follow along with the rest of this guide to optimize your settings. GUIMiner-scrypt is just a GUI to cgminer and reaper anyways. If you are using a command-line miner, like reaper and cgminer, I recommend you download and isntall Notepad++ or SublimeText if on Linux. Reaper is currently considered to be the best tool for mining. After you unzip your downloaded file, in the folder you'll find reaper.conf. It should look something like this:
As you see, my thread concurrency is slightly different from the default of GUIMiner-scrypt. I found that this concurrency gives me the best hashrate! NOTE: I do not use cgminer to mine litecoin. If you plan on using cgminer, which offers more hardware-controlling settings, in the cgminer folder you will want to create a text file. Then, open that text file w/ Notepad++ or SublimeText, then Save As > cgminer.con > file type > all. This will save the file with the proper name and as the proper type. Note that cgminer does not support high concurrencies. For me, cgminer.conf would look something like:
You saw some settings similar to what we saw in Reaper's litecoin.conf. The other settings have to do with my card's clocks, voltage, and fan. This is covered in the overclocking section right below! Overclocking (aka the risky part) Okay, first off I'm not responsible if you cause damage to your parts. Please research safe overclock settings for your card. Second, don't be afraid. Modern hardware has many safety features in place that help prevent mayhem like me...lol jk this isn't a car insurance add. For your better understanding, become familiar with these terms:
Voltage/vddc: Amount of electrical current supplied to your card
Power Limit: Determines at what temperature your card throttles itself
Core Clock: Speed of your memory's core, similar to CPU core clocks
Memory Clock: Speed of GPU's GRAM, similar to RAM speed
Fan speed (%): Determines the RPM of your fan once your card reaches certain temperatures.
No one setting controls how effectively you mine; what matters most when it comes to clocks is the ratio between your core/memory clocks. Generally, a ratio of 0.7 or below is best. You will need to experiment. If you're using cgminer, you can control card settings from the conf file. However, if you aren't, I recommend using MSI Afterburner as your overclocking tool. You will need to unlock some settings. Using my cgminer settings, MSI Afterburner looks like this. I have found these settings to be the most stable while bringing me a high hashrate. Other people's optimum settings You can check the sidebar for the hardware comparison chart, but it is rarely updated and has huge sways in results. It is a good starting place. The mods of this subreddit will be putting together an updated, more accurate list in the near future. END I hope all things go smoothly for you and that you've learned a lot!

Hey all! I setup CGMiner on a RaspberyPI with a ASICMiner USB miner (330MH/s) with the intent of setting it up in my office as a talking point/cool display as we love bitcoin. I installed a number of libraries, CGMiner, plugged in the miner, got a wallet, joined a pool... Ya know... All the good stuff. The only bummer is that when I start up CGMiner, it looks like the miner is failing to start:
Hello i am new here and this is my first post. So please don't hesitate to say if i have put this topic in wrong place or formated it wrong. So i recently to get in to bitcoins and alternative cryptocurrencies and i thought i might give VertCoin a shoot. I have mined some coins before as bitcoin, FlutterCoin and DogeCoin. Just for fun and not for profit ^ I used Cudaminer beacuse i have A nVidia graphic card. As usual i downloaded the wallet and registered to a pool this https://vtcpool.co.uk/index.php I did as the instruction said and setup the url and pass and so on ... "To get started, point your miner at stratrum+tcp://p2pool.vtcpool.co.uk:9171 with your username set to your VTC address and any password." But i thought it was wierd to use your VTC adress as username. I have never seen before that you should use your wallet adress as username. But i thought what ever i am just noob and followed the instructions.I saw that the pages said i should use cGminer but for nVidia user Cudaminer is better so i just adjusted the code so it worked on CudaMiner. Code looks like this cudaminer.exe -o stratum+tcp://p2pool.vtcpool.co.uk:9171 -O VbcqKse4rxU5FTsZNaxLsV8ht421WurSB3:123 I know it is not anything fancy but i am new here so whatever. However when i use this in the run.bat i get crazy amount of shares like 20 "good" shares in 10 seconds. Think i got like 4000 shares in 10 hours is this normal in VertCoin? i have a Geforce 550 ti graphic card. My question is am i doing it right? When do i get my VertCoins? I have also read that only cgMiner can mine Vertcoins, but then how can my CudaMiner work? I would be very happy if i could get some anwsears. Source: http://p2pool.vtcpool.co.uk:9171/static/
New CryptoCoin launch preperation guide; I've created this short guide for new users who want to jump in on the mining of a newly launched coins. Being prepared and getting on the network immediately will lead to you finding the earliest blocks (some coins have block rewards that are higher in the beginning) Step One - Prepare the Data/Wallet directory The first step in this guide will be to setup the directory that will hold your wallet data, config file and blockchain store. We want to set this up first so we can immediately start solo mining without screwing around with settings that are common across all CryptoCoin wallets. Windows 7/8; C:\Users\YOURUSERNAME\Appdata\Roaming\COIN_NAME Windows XP; C:\Documents and Settings\YOURUSERNAME\Appdata\Roaming\COIN_NAME Linux; ~/.coinname/ MacOS X - ~/Library/Application Support/ Create a directory in one of the above directories that will match the name of the coin (ie: Bitcoin). In this directory we are going to make the default .conf file; Default options listed in the COINNAME.conf will be as follows; server=1 listen=1 daemon=1 rpcuser=YOUR_DESIRED_USER_NAME rpcpassword=YOUR_DESIRED_PASSWORD rpcport=NUMERIC_PORT_TO_LISTEN_ON rpcconnect=127.0.0.1 Change the rpcport parameter to a generic port # if you plan on only having one batch file to start solo mining. WARNING, this method will interfere with mining if multiple wallets are running using the same port number. If the launch forum post lists default rpcport #s, use them instead of one generic port. (cryptocointalk/bitcointalk). Pay attention to the original launch information forum post, adding nodes with addnode=ipaddress, can help speed up node discovery and wallet sync. You can add these options fairly quickly with a cut and paste. If you have multiple rigs and plan to throw their hashes at the wallet if it's not on the same machine, use the .conf option rpcallowip=your.network.address.* (eg: rpcallowip=192.168.0.*). Step Two - Create your .bat file If you've been mining for awhile, this should be a simple step, otherwise, it is beyond this tutorial on how to fine tune your mining software. The .bat file should only be a few lines long; setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_USE_SYNC_OBJECTS 1 cgminer --scrypt -o http://127.0.0.1:WALLET_RPCPORT_PARAM -u YOUR_USERNAME -p YOUR_PASSWORD the_rest_of_your_miner_config_here This is the default for scrypt mining. Always pay attention to the announcement post for specific mining options (CPU only, keccek, scrypt-n, etc). Change the IP address in -o option to your wallet machines ip address, should be you mining from a different machine. (making sure to set the above rpcallowip= correctly) note: adding gen=1 to your config file will automatically start the wallets internal block generation routine, by passing the need to start your mining software. Just remember to edit this option later if you run the wallet continually and do no plan to directly mine. Step Three - Mine! Download and install/extract wallet, run the wallet. If everything is set correctly, you should be ahead of the game and finding blocks very quickly. If you've found this post informative, I'm never opposed to receiving gifts of Litecoin :D LXFE81zFSTkzsV1TrRCtdy781F1aiEfYHe also: If you have any additions to this guide, please PM or comment, so that I may correct any errors I may have included. edit: formatting.
