⚡ DIY: Making 2000 Instant Volts Using a 18650 Cell Have you ever wanted to generate a high-voltage pulse (like 2000V) using just a simple 3.7V 18650 battery? It’s possible with basic components by applying step-up (boost) circuit techniques. Here's how! 🧪 What You'll Make A small circuit that gives ~2000V pulses , useful for: Electric lighters Bug zappers Ignition sparks Small stun circuits ⚠️ Caution : High voltage can be dangerous! Only for educational and safe usage. 🔧 Components Needed Component Description 18650 Cell 3.7V rechargeable lithium battery Push Button Switch To control pulse manually Transformer (Ignition Coil / Joule Thief coil) For step-up voltage NPN Transistor e.g., 2N2222 or D882 1K Resistor Base resistor for transistor Flyback Diode (optional) For safety Capacitor (1nF–10nF) For pulsed discharge (optional) Wires & PCB/Perfboard For assembly 🛠 Circuit Diagram (Concept) less Copy Edit [18650 Battery +] --- > [Switch]...
