I used to love playing with the Tesla Coils at the mall but never wanted to fork over the cash for one. Now this helpful guide will show me how to build my own Tesla Coil right at home. However please be careful:
Bring it outside for its first run, as it really isn’t safe to run anything this potentially powerful indoors, there is a high risk of fire. Flip the switch and enjoy the light show. My NST, at 9Kv at 30mA, makes the coil give off 6 inch sparks.
