Interesting experiment with an transformer, 2 lamps, diodes and an magnet

[GM]

Here is the diagram of the circuit.

Sorry, no infos about the core. But it is wounded with 42 turns of tesla wire each side.
This are "my" ferrit cores, not exactly this cores, but its the same seller and the same cores.

Bye, Markus


edit:
Sorry, there were two mistakes in the diagramm.

Here is the correct circuit diagram

(changes: freq. poti is 100K instead of 10K and the MOS FET is connected between + 9V and the load, not between ground and the load)

Hi Markus, thanks for the circuit diagramm.
Well without scopeshots one really could not tell much,
what is going on in the circuit.
Can you make some scopeshots and post them ?

Maybe you also just only alter the duty cycle of the frequency
generator, cause you have a 1 KOhm resistor in the
power supply line for it and there might be still some coupling
via the small diameter ground lines...

Without scope shots one could really not tell, what isgoing on there...

Well, then we have to wait until I own a scope (I am low on money) or someone who own a scope is willing to reproduce this experiment.

would this help?

There are lots more if you Google
I think this one is free. The other was free for 2 weeks
