@Inquorate,

Take your time. :-)

I will solder the 555 circuit tomorrow and post the cleaned up drawing then.

Groundloop.

the capacitor is 0.22uF, the duty cycle pot between pins 7 and 8 is 5k, I had it set on 2.2k. The off time pot is 20k, I had it on 16k, to avoid boiling the charge battery.

I had it like this .  .  .  .  .  .  .
But it could also be like this ....    ....    ....
To avoid boiling as well, but a computer controlled pic chip would be better to investigate that.

@Inquorate,

Thank you for the information.
Attached is a cleaned up version of your circuit
and also the switch circuit.

Will be testing soon.

Hi guys any help please? I've biuld a bedini circuit but the thing is that the coil is only hissing no oscillations is happening. Someone had told me to lessen the resistance on the base but it's zero resistance on the pot.
Should I lessen the coil than?
Thanks

@guruji,

Post a circuit drawing of your setup and we will find a solution.
