For those of you fascinated with electronics and big sparks, you might want to consider making yourself (or your friends) one of these vacuum tube tesla coils. Not only are they great conversation-starters, they can be great for parties at your home, just make sure to put some protection around it so people don’t get zapped!
Can’t find a neon sign transformer? Don’t want to face the complexity of building a Solid State Tesla Coil just yet but want big sparks? If so, then a Vacuum Tube Tesla Coil might just be the right thing for you. You can build this relatively simple little coil in a weekend and throw roaring sparks several inches long!
