Bitcoin Home Mining - Upgrade your miners!

This is how you can improve efficiency, reduce noise and overclock your S19 jPro Antminers. Here I have added Zack Bombsta's Njord board fan controller, an AC Infinity 800 cfm fan, a 3D printed duct from Fruits & Associates and BraiinsOS firmware.

This machine started as a 92Th miner and is now producing 117Th more efficiently and with less noise.
