life TINYenormous – Build it up to break it down again arduino, robots, cameras, and life part 2 – how to log in to your amazon ec2 dogeminer In part 1 we covered the groundwork you need in order to get a miner instance up and running on amazon’s servers. Now we are going to log in and put your info to work. Before we log in to your instance, we need to set up a worker in your pool. Most will set one up for you by default, but you want to double check. Log in to whatever pool you selected. I suggested doge.hashfaster.com. Go to the worker section on the left side of the page. you should have a section that has worker configurations in it. It will have your username followed by a box, and another box for a password. Make easy to remember, short entries. The general practice is to use numbers in the first and a single character in the second. The only harm someone could do with this info is that they could mine for you! Make it simple. You don’t want to mine and have it not get credited to your account. Look at the worker info again and remember it. It should be in the form of username.1:password for instance, mine is tinyenormous.1:x In order to log in to your instance you need -your key (from amazon) -the ip address of the instance There are a lot of ways to ssh, but I’m going to use the terminal. First I’m going to change the permissions on the key. chmod 400 /path/to/your/key next I’m going to wait until the instance shows up in the dashboard and copy the ip address. Then I type ssh -i /path/to/your/key ubuntu@PasteYourIPRightHere and you should be in! On log in, the first prompt will ask you for your pool server address. This will look like stratum+tcp://stratum-us.doge.hashfaster.com:3339 note that it begins with stratum+tcp and ends with :3339. Those things may change from server to server, but it’s important to have them in there and correct. Next up is your WORKER username and password. Enter it exactly as I showed it above username.1:x Hit return and your miner will spring to life! In order to check on it’s progress type cat minerd.log and it will read the log that your miner is writing. After a few minutes your pool dashboard should show your speed on it. The pool dashboard number is often off, and should only really be used in order to see if you have successfully connected. This is obviously just the beginning of cloud mining, so feel free to poke around, fire up more instances, or tweak the settings!

Mining in the cloud! I’ve seen a few tutorials out there showing how to mine dogecoins, bitcoins, or litecoins in the cloud. None of them were as complete as I wanted them to be, so I’m putting this post together. WHY mine using amazon’s servers? Good question. Generally setting up a mining computer will be cheaper in the long run, but it involves more technical know-how and it involves a lot more money. You have to pick out the ‘right’ motherboard, graphics card, hard drive, a case, and then you have to put it all together and get it to work. With Amazon’s servers, you could be up and running in 20 minutes. Using your own hardware also means that you are capped at a certain rate. If the price of dogecoin increases 200% tomorrow, then you could simply fire up more servers. It would take a lot longer to order up the parts for more mining computers. The downside is that amazon’s prices fluctuate, and amazon will rent you a computer that will barely break even, or not make a profit. That onus is on you in order to do the math. HOW to mine dogecoins on amazon. 1 – Download the dogecoin client – from here . Run it and let it sync. It will take a long time (days!) but it will run in the background and you don’t need to wait for it to finish in order to continue on. 2 – Get your dogecoin address – In the dogecoin client go to the third tab in. Much Recieve” Select the only entry and hit the copy Address” button. This string of characters is similar to your checkbook routing number. This is where you will get paid for your mining. Save this number somewhere, you will need it later. 3 – Join a pool – Mining is a lot like playing the lottery. You try and try and eventually win. If you have an underpowered machine, then it may take a VERY, VERY, long time for you to ever find a winner. Consequently, people have created pools” where everyone mines together and then splits the winnings based on how hard they worked. This is generally the better way to do it, as you will be paid more consistently. My current favorite is hashfaster . 4 – Join an exchange – Cryptsy will allow you to trade your dogecoin for bitcoin, litecoin, or a lot of other coins. This will let you hedge your bets and give you a place to swap one coin for another. Join here , we’ll come back to this in step 2. 5 – (finally!) Set up an ec2 account – Sign up here for the ec2 free tier. Don’t worry, they won’t charge you for anything until you start renting servers. 5a – Create an instance – Once logged in to ec2, click on Instances” on the left side, and then on Launch Instance” on the top. 5b – Find my AMI – On the left side click on Community AMIs” and then type tinyenormous into the search box. I should probably explain what this means. I have configured a machine image so that it will start mining as soon as it starts up and is configurable. You could do this if you wanted to, but it is easier to simply use the one that I have already set up. Search for TINYENORMOUS” and you should find mine. Just to be safe, here are the specific ID numbers of the authentic ones. ami-2b5f6242 – east coast ami-8ae4d6cf – california ami-eaddbcda – oregon ami-f3ac32c9 – sydney ami-e60553b4 – singapore ami-a3a4cda2 – Tokyo 5c – Choose an instance type – In this section you will pick the computer” that you will be renting. This AMI is going to be cpu mining, so the number of vCPUs is the most important thing. Generally you will get ~4.5k per cpu. Amazon has configurations that run anywhere from 1 to 32 cpus. It doesn’t matter if you have one machine running 32 cpus or 32 machines running one, so check the prices and find the sweet spot. In order to find the prices you can do two things. The first way is to select a configuration and hit the next button. Then hit the show spot prices” radio button on the next screen. This shows you the current pricing for that configuration. The other way is to open up a new ec2 tab inthat has been a good thing. I had to set my bed size, x,y,z, max length, nozzle size, filament, filament size, and possibly a few other things. There is a first run wizard that guides you through the things that you need to change. The one big sticking point is that you (strangely) need to put your extruder steps per mm into cura. I’m not sure if it was in the wizard. If it wasn’t then you can find it under preferences called steps per E” SLICING & PRINTING – The slicer in cura is well laid out and labeled. It is a little slower than slic3r, but gave me better results. It also allows me to tweak things like speed (by a lot) and have much more consistent results. COOL THINGS ABOUT CURA – There is a project planner feature that is pretty awesome. It is a plater, in that it allows you to gang up multiple pieces in one print but it allows you to apply different slicing settings to each piece. Being able to print a wade’s extruder at .2 layers and the gears at .1 on the same bed is really awesome. The coolest thing about project planner is that you can control whether the separate parts are printed individually or all at the same time. I can’t count the number of times that a 3×3 grid of gears will have one gear come up...
