Raspberry Pi 3 Cluster for Mining Steem

<html>
<h1><strong>Building a Mining rig with 40 Raspberry Pi 3</strong></h1>
<p><img src="https://s32.postimg.org/6sc2dz1yt/PI_2145.jpg" width="800" height="600"/></p>
<p>List of items:</p>
<ul>
  <li>40 Raspberry Pis</li>
  <li>40 3ft Ethernet Cables</li>
  <li>48 Port Switch (Rack-mountable)</li>
  <li>Bitscope Rack 40 (Rack-mountable)</li>
  <li>2 Adjustable Power Supplies</li>
  <li>40 Pi Heatsink Kits</li>
</ul>
<p><strong>Gather some Pi, collect SD cards and heatsinks.</strong></p>
<p><img src="https://s32.postimg.org/qulqwls51/PI_2151.jpg" width="800" height="600"/></p>
<p><strong>Add heatsinks to the Pis.</strong></p>
<p><img src="https://s32.postimg.org/mmqynuqph/PI_2152.jpg" width="800" height="600"/></p>
<p><strong>Add Pis to Bitscope Blade. Screw in.&nbsp;</strong></p>
<p><em><strong>Note:</strong></em><em> You don't actually need to take the blades out of the Bitscope Rack 40 if you have nimble fingers. I only did so for the photos.</em></p>
<p><img src="https://s32.postimg.org/cdyhi12np/PI_2153.jpg" width="800" height="600"/></p>
<p><strong>Fill the Bitscope Rack 40 with all your Pis.</strong></p>
<p><img src="https://s32.postimg.org/bpu8cttbp/PI_2159.jpg" width="800" height="600"/></p>
<p><img src="https://s32.postimg.org/lqz2m56et/PI_2162.jpg" width="800" height="600"/></p>
<p>See the one missing? Its going to be the head node. We will cover that in the next post.</p>
<p><strong>Close up the Bitscope Rack 40 and start wiring all the Ethernet Cables. Make them look good.</strong></p>
<p><img src="https://s32.postimg.org/5h8wj8vqt/PI_2163.jpg" width="800" height="600"/></p>
<p>Connect the Cables to your Switch!</p>
<p><img src="https://s32.postimg.org/5iiucnxkl/PI_2164.jpg" width="800" height="600"/></p>
<p>Now we wait for the next post where we will cover software, the head node and adding mining tools.</p>

That's a pretty cool cluster!

If you get bored in the future, there's room for your rig over at <a href="https://www.gridcoin.us">Gridcoin</a>, you could crunch SETI@home, Einstein@home, Enigma@Home and a couple others.

Hell yea!  This is the kinda of stuff I like to see.  Just curious are you building the STEEM wallet and then installing CPU miner?  I've seen several toturials and my mining operation has failed.  I'm running a droplet on digital ocean and have an instance on AWS both running Ubuntu.

I'd be happy to get the wallet compiled for straters.

I don't really know how yet. I will figure it out for the next post! :) I am pretty sure I will be using CPU miner, but might modify it to use the GPUs. We will see... The next post will have a lot more information.

Very cool.  I wouldn't mind getting in touch with you whenever you have things up and running.  I have a RPI 3 myself collecting dust and wouldn't mind putting it to use.

How to config the config.ini files between machines ? I mean the miner and witness section.

Yes learning a lot. Learning also that mining steem is not worth it. Good thing this rig is good for so much more. Installing spark on it.

So,  I think this is sadly impossible.  

Did you ever get it to work?  Reason I think it's impossible:  RAM.

I ran into some issues but not that one. Unfortunately, the project is on hold for now. After looking into the mining of Steem more and looking into Steem more in general, I don't think it is worth it. Good thing that equipment will serve a lot of other purposes.
