Selfcharging cap circuit from Larskro fake or real ?

It's a slide switch. It connects the battery's positive to the reed switch in the loop off position.

I may have found a possible "Tell" in the video below. If you play the video from 1:00 minute when he says "loop on" the camera goes to the meter then we can hear an audible click in the background (like the sound of a switch) the rpm increases. Then at the end why does he say "stop" ? Is he telling the machine to stop or his assistant ?

Geeze, this sounds really familiar...does anyone remember....

"You can turn it off now Tony..." from the Mylow saga?

Nice catch Farmhand, that went right past me.

That's a pretty good trick... since the battery is _unplugged_.  Can you tell me where I can find such a slide switch?

Meanwhile, here's MiniPulse II, with bipolar transistor instead of mosfet, running down to the limit of the Hall sensor's switching at just under 2.4 volts. Runs well on supercap, makes spikes 3x input voltage but still no voltage climb effect. I can't find any reed switches in my stashbox....

OK can anyone give a fairly accurate approximation of how much "energy" can be stored in 20 mAh NiMH battery as compared to a 0.47 Farad capacitor both at 3.7 volts.

A 0.47 Farad cap has 3.22 Joules according to the electronic assistant app.

A 20 mAh battery at 3.7 volts should give 20 mA for an hour at about 3.7 volts ? about 266 Watt seconds ?

Clearly I've confused myself. I think. 

Tinsel, another cool little motor. Strobe attack is neat too.

Maybe I should try to test the battery and see what I can get out, try to plot a curve or something.
