Transformator Tesla Na Ne555

PDF The Tesla coil, invented in the 1890s, has found applications in areas as varied as radio-technology. This essentially short circuits the transformer and capacitor bank through the primary. 100kHz 29.3m na*. Are created with a NE555 astable square wave generating circuit to allow precise tuning via a 10 turn. Sony content browser 2 serial.

Here I've used two separate power supplies-a 6V powering the NE555 and a 12V powering the 2N3055 and the flyback.I've also used a COSMO 1010 (C1010) photocoupler to make sure that the NE555 doesnt blow from the 12volt supply. The coil The secondary coil has about 400 turns of 0.4mm magnet wire wrapped around a 3cm paper roll.The primary is 5 turns of speaker wire. The spark gap Just two screws not attached to anything facing each other.

The calculations were wrong -this was too much capacitance.I've replaced this chain of capacitors with a single DIY aluminum foil and plastic sheets as dielectric capacitor.I am not aware of the capacitance value of this though.I do not own an LC meter. Here is how I made this homebrew capacitor. Maybe the bank is not good enough for spark on top.Maybe the bank is the culprit.

How to get the constant spark on top? I know it has something to to do with resonance.Obviously there is no resonance here.
