While there are many ways to produce audible sound, Plasma Speakers have to be one of the coolest. Usually very complex and expensive, we received a tip for a beginners guide to making one of these impressive novelties. Handily included are a set of schematics (one very simple schematic, the other with a few artistic illustrations). There are also a set of warnings, which include sound advice to mind the heat generated by the MOSFETs, as well as making sure that your input signal isn’t too strong. The finished product is fun to listen to, so be sure to check out the example video after the break.
