Post a video if possible, this looks interesting!

CD yes that will lite a bulb for a few seconds as you built a Tesla feedback transformer and tank circut. the transformer will triple the voltage and the cap will hold the volatge for a short time and needs to be regenerated. I belive Tesla used thih to bleed off power so not to over load a circut we call this a soft start for motors today Greenly sells a circut that has on of these in to to control large machines to lower in inrush current.

Hello Macedonia CD,

Have you tried to replace C2 20000uF electrolytic capacitor first with a 4700uF to see the charging time can be reduced? If time gets reduced, you may find ways to reduce the inner impedance of the rest of your circuit that charges up the capacitor.  The RC time constant!

My questions:

P1 is a MOSFET switch?

What value has got C1?

The speed  diode is again the double diode from a PC supply but only one half of it is used?

Regards
Gyula

How long does the bulb stay lit after you wait until the cap is charged? If its only a short while or a mere flash than this is no more than a simple transformer similar to that found in portable cameras for the flash bulb (which store a higher voltage charge in a capacitor and discharge it when needed).

If I understand his Reply #4 above correctly, the bulb is lit for 2 seconds, the charging time is 10 seconds...
