This is so f'n cool! I'm running a single S19j Pro hashboard on an S9 power supply on a standard US 120V outlet!

All possible thanks to Zack Bomsta's Loki board!

A used S19j Pro feels like a sweet spot right now for a modern-enough miner at a relatively cheap price (~$8.25/Th; mines at break even around 11-12¢/kWh). But it pulls 3000W from a 240V line that most US households don't have.

But with the Loki boards, you can DIY one S19j Pro into three separate miners / space heaters. Each running on their own old S9 power supply which won't overload the typical 15A household circuit.

So now I can just plug in a ~35+Th/s miner in the coldest room of my mom's house!
