  • Input power 10V - 35V from 5V USB powered step up converter or notebook 19V power supply.
  • Frequency 2Mhz - 4Mhz
  • No special components, just red LED, BUL45 transistor or another, and 82K resistor

It is very simple device but require precise PCB board manufacturing

You can experiment with different transistors, voltages etc...

It is not making sparks but can light neon tubes ... check on video
