FREE and open-source Bitcoin mining hardware update: Prototype 2, revised S19j / S19k / S19 Pro single-hashboard HeatHarvest case, custom-built for a specific role in the HeatHarvest greenhouse and designed to be semi-waterproof.

Keep in mind, one of the primary goals of this design is to be modular and printable on a modest small-bed 3D printer, so the average pleb Bitcoin miner can make it at an affordable cost.

Made about a dozen modification notes, and now it’s back to CAD for the next revision. Stay tuned.

How it started, how it’s going. #bitcoin
