Slayer Exciter Tesla Coil – Minimalist Fun! ⚡ I just built a Slayer Exciter Tesla Coil, and it’s amazing how much it does with so little! This simple self-oscillating circuit uses only three main components to generate high-voltage, low-current sparks. Added a blue LED with a 5.6 kΩ resistor for a visual indicator—it looks awesome when it’s running. Such a tiny setup, yet so satisfying to see in action!
