The new oneTesla interrupter can be used without a MIDI input in standalone/fixed frequency mode. A toggle switch changes between standalone and MIDI mode.
The MIDI interrupter is no longer available because we now sell an SD interrupter, which does everything featured in this video and more! The SD interrupter has everything you need to control your oenTeslaTS DIY Musical Tesla Coil Kit or tinyTesla! Check it out: http://onetesla.com/products/kits/int...
