tinyTesla is a Solid-State Tesla Coil (SSTC), which has a non-resonant primary and a resonant secondary. Because the feedback loop locks on to the resonant frequency of the secondary, not the primary, tinyTesla is insensitive to its surroundings, allowing you to safely pull arcs off the coil with a metal object (pulling an arc with your finger will result in a nasty burn and is not recommended!).
The tinyTesla interrupter connects to your computer via USB and can be controlled using our own software or many other MIDI playback programs. tinyTesla can also be controlled through a MIDI instrument (such as a piano keyboard) using a USB to MIDI adapter and our software, which allows the input from the adapter to be passed through to the interrupter.
