I just wanted to try out burning wood with electricity, using my DIY zvs driver,. All you need is a high voltage source, some wood, and tap water. Oh and some common sense, that always a good thing.
Be careful if you want to make your own. This set up can kill...
What type of wood did you use? Have you tried that out in different kinds of wood?
Im not sure, I used the left over wood that I bought from Lowes. I think the denser the wood, the better the figures come out. If it is soft you, may get the arcs to form internally. But I havent tried it on different types of wood.
