What is this?
A virtual piano keyboard that generates precise audio frequencies for your Tesla coil. Each key produces a tone that drives your coil's interrupter, turning key presses into lightning arcs at specific musical pitches.
Controls
Tap the on-screen keys or use your computer keyboard to play notes. The keyboard supports multi-touch for chords. Adjust the octave range to explore different pitch registers.
Use with a Tesla coil
Connect via Bluetooth to your coil's interrupter. Each note you play creates electrical arcs at that frequency — higher notes make shorter, snappier arcs; lower notes produce longer, more resonant ones.
