Build Your Own Mini Tesla Pen: Easy DIY Electric Experiment 🖊️

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.
