A solid state teslacoil is a device that generates high voltages using tesla's resonance theory. basically its a transformer with a few windings primary and a very high number secondary. in my case 7 primary and 750 secondary.

This transformer only works when the right (resonance) frequency is applied at the primary. When applied correctly, a tremendous voltage will be genereted at the secondary coil (the 750 windings). which in my case has reached a maximum of 131.000 volts. these high voltages will couse the air to conduct locally, what you can see as corona. The electricity is actually coming off the tip.

When the air comes in conductance, it will heat up and expand rapidly like a ligtningbolt, but smaller. this generates vibrations in the air, also known as sound.

By switching this device on and off at the frequency of sound (20- 20KHz), you can actually make diffrent hearable tones on this device.

When an audio signal is used to interrupt this teslacoil, that sound will become hearable by the corona switchin on and off.

The sound you hear is actually comming fom the corona you hear!!

Have fun waching:)
