The secondary winding is 48 cm long, 7.2 cm diameter, 0.3 mm wire (pipe is 55 cm long).
The primary winding has 8 turns of very thick coaxial cable.
The capacitor is made of glass planes, capacity 12nF.
Spark gap is static, made of 4 copper tubes (10 x 120mm).
This tesla coil is powered by two MOTs, current limited by additional two MOTs.
Sparks to the air are 35 cm. The next time I would probably use more input voltage and bigger capacitor :).
I found that the capacitor is the most tricky part of the Tesla coil.
!!! WARNING !!! Tesla coil is an extremely dangerous device!
Its supply voltage is deadly! Without knowledge of the principles of working with high voltage, you can not construct it.
Tesla coil causes a broadband radio frequency interference. Electromagnetic
radiation can damage electronic devices or storage media. The spark gap produces
ozone (O 3), nitrogen oxides and other toxic gases, they have to be ventilated!
Spark gap emits UV radiation. Current at ignition
discharge of up to several kiloampers. Capacitor can remain charged even after shutdown. The device is very noisy and can damage hearing. Everything you do at your own risk!
For any injury or damage I do not take any responsibility.
