Could you build one with an old Bitcoin miner?
Discussion
Probably, if I knew enough about them. I'm a DCA stacker. Not a techno miner unfortunately
DCA is the way to go. Haven’t gotten to the mining part of my journey but I’ve seen enough S9 heaters to think if all you need is heat and you were already thinking about needing a kiln then IF you don’t do it a competitor WILL.
FYI I tried to zap your note and it failed. 😞
