This is based on a TV flyback coil and a single 2N3055 power transistor and other on-hand components giving a 1/2 inch spark at 20 V 3 A input.

Don’t put your hand in this one! This uses a disposable camera photoflash running off 3 V using a BD140 and heatsink substituted for the main HV transistor so it can now run at 1.5 A.

This variable frequency flyback supply 4 kV AC was built after it was mentioned the Physics Dept needed a variable 50 -100 kHz sine wave supply between 1-2 kV.

These are odd little high voltage generators which are in principle, part Blumlein generator (like the nitrogen laser uses) and part induction coil. They are compact and easy to make.

This 300 kg x-ray transformer 60 kV DC at 300 mA has 3 phase 240 V 45 A input. It is capable of making an arc drawn out to 2 feet just on 1 phase 240 V so it is a serious piece of HV gear.

Expect an electro/experimental/ambient sound experience
Expect Half a million volts of Tesla coil goodness generating sound.
This is sound to make your ears bleed so it is woven into the music.
Don’t expect pop-tunes
