800W Tesla from $30 ZVS Driver

In this video, I’ll show you how to make an 800 W continuous wave tesla cool starting with a cheap $30 ZVS module. These modules are readily available on EBay. The main thing to get this to work is to have a tuned system. If the primary and secondary coils are not in tune, then it will not work.
Here is a way for tuning without signal generator or oscilloscope:
The best way is to use a neon bulb. You need to start with a low capacitance for your tank circuit. Something around 150 nF. The tank circuit should use a polypropylene capacitor such as MKP that can handle high frequencies and high current. With the secondary centered in the primary. Ground the lowest turn on the secondary to earth ground. Then make sure both coils are wound in the same direction. Or reverse the connections on the primary if they are not wound in the same direction. Use a moveable tap point on the primary. Place neon bulb close to secondary. Apply low voltage around 12-15V to ZVS. Keep neon bulb at fixed distance from top of secondary. Then change tap point position until neon bulb lights the brightest. Then move neon bulb away from secondary. Then move tap point until it lights again and adjust for it to be brightest. It helps if the terminals on the neon bulb are grounded. Maximum brightness means secondary and primary are at the same resonant frequency. For fine tuning, adjust the size, length and shape of the breakout point. Sharp point is better. This setup will not work with a toroid.
