First full power test of the Tesla coil playing music 'Popcorn' - single MIDI channel.
The sparks are producing the music, as we space the time between sparks, ie 260 sparks per seconds you get a middle c sound. Speed up the rate you get higher pitch sounds. Do this dynamically using a MIDI (musical instrument digital interface) and it plays music.
Bridge: 2x Eupec BSM150GB1200DN2 IGBT's in full bridge configuration
Supply: 240V. 10A rectified bridge, 3x1800uF 420V capacitors in parallel
Primary: Inner diameter 15cm, 4.5 turns, 6mm copper at 6mm edge to edge spacing. Currently not water cooled - this will need to happen as it gets pretty hot.
MMC: 8 Dawncap DTR 0.44uF 6000V in 2P4S configuration
Secondary: 1500 turns of 0.31mm wire, 11cm diameter, 62cm long
Secondary Resonate Frequency: 138kHz Primary at 130kHz.
Topload: 3d printed 15cm x 55cm covered in foil tape
Driver: UD2.7C. OCD set at 400amps
