Mini Tesla Coil Schematic
Primary Circuit:
– 9-12V DC Power Source
– R1 (1kΩ, 1/4W) – Base Resistor
– Q1 ( TIP41C/ BD243 ) – Transistor
– D1 (LED / 1N4148) – Diode
– Primary Winding (18-gauge, 5-10 turns)
Secondary Circuit:
– Core Rod (1cm wide, 5.5cm long)
– Secondary Winding (28-gauge, 150-250 turns)
– C1 (10-22nF, 1-2kV) – Capacitor
Connections:
– Power Source (+) to R1, then to Q1 (base)
– Q1 (collector) to Primary Winding
– Primary Winding to D1 (anode), then to Power Source (-)
– Secondary Winding to C1, then to Ferrite Core Rod
Optional:
– R2 (10-100kΩ, 1/4W) – Additional Protection Resistor (connect in series with Q1 base)
Remember to follow proper safety precautions when working with high-voltage circuits.
