Selfcharging cap circuit from Larskro fake or real ?

Just for you Synchro, here is a "big relay vibrator/oscillator" I made using car points as more or less a reed switch, it's action was surprisingly rapid if it was adjusted to the smallest workable gap. The points could do with some snubbing maybe. At the end running the motor the points look like a true spark gap but it's powered by only 12 volts. There is a lot of heat loss there.

It was a good and simple vibrator magnetic switch, quickest I've made.  I'd like to see a reed switch take what I did to those points.

Big relay clip.

It worked well enough to practice Morse, I attached a speaker as well as the light. hahahahhaha The message is factual.

Lidmotor gets rid of the magnet motor altogether:

The fly back voltage is higher voltage then the power pulse, so it can overcome more resistance in switch gap. That's how the "Reed Switch" can disconnect from the circuit to cause the coil field to collapse , but still have it's electrodes in close enough adjacency to allow the higher voltage fly back power to jump the gap as a connection! The overall greater inefficiency and retarded speed of the "Reed Switch" are behind it's secret strength.

Take a look at Igor's schematic in his "REED SWITCH" II video:

Igor just jumps his magnetc switch with an LED anode to positive, and gets a self runner!
