- Simple and fun DIY tesla coil. The voltage is boosted to tens of thousands of volts and powerfully discharges through the air between the two high-voltage plates.
- The circuit uses a 3.7v battery, you can use a voltage greater than 20v and replace the 500ohm resistor. To be higher voltage, strong heat. The circuit uses transistor NPN D718, resistor 100k, pulse diode 4007.
