Can you make a Jacob's Ladder into a speaker? Answered
So Information Unlimited has a Jacob's Ladder that apparently generates not just crackles but high fidelity music or whatever sound you pipe in.
It looks fascinating, and I would love to buy a kit, but apparently they only sell the finished version.
I wounder if anyone here has the know how to reverse engineer such a thing, or perhaps knows how to make one already.
Really, $169 for the completed thing seems reasonable to me. I have nothing against buying one exactly, I just want to build it.
