My goal is to somehow nerf a antminer s9 harshboard to only use 1-5 asic chips using the standard control board. Anyone know how this could be done?
I don't think that's possible. I'd recommend selling that S9 (they're worth around $500), and getting the
R909 for $600. Great little machine.
It runs off of 12V, but I doubt that a solar panel of the size you need only outputs 5V. They are usually 12V or higher.
