Tesla coils are pretty awesome, but they tend to be big, unwieldy, and kind of difficult to seriously consider as a purchase. The Tiny Musical Tesla Coil however is only 6 inches tall when assembled, and can easily do its magic on a countertop. The best feature of this particular kit however is its ability to play music. With a USB cable and your laptop, you’ll be able to play MIDI tunes by controlling the pressure waves generated by the 4 inch sparks. Some assembly is necessary, so you’ll need at least some basic soldering knowledge, as well as access to a soldering iron, paint-on or spray-on varnish, and hand tools. It’s a single-resonant solid-state coil (SSTC Tesla Coil), which is great because it’s reliable and safe. You’ll be learning about alternating-current electricity in a very hands-on, and let’s face it, pretty cool manner. And you’ll only have to pay $229 for the privilege.
