Re: look at this

Hey those are cute for $1.50 unbelievably cheap. I'm putting one on my variac's output, add a third wire to it for mains power+sense, as it supposedly conks out below 110V.

Second video Big Clive reverse engineers it (don't watch the second part hydrogen-filled condom lol)

Thanks for the heads up
