Meet tinyTesla: a mini musical Tesla coil kit for makers that shoots sparks up to 4″. You can control your Tesla coil from your laptop and make music using the sparks. The kit doesn’t have too many components, so you can build it quickly. By putting your singing Tesla coil together, you will learn a few things about electronics.
The kit comes with a driver PCB, USB interrupter, spun aluminum toroid, pre-wound coil, screws, and other hardware components you need to get started. The above videos cover what you get.
