Self Running Micro TPU, with closed loop.

I only connect probes when I need to see the wave and the voltage meter is off all the time and on only when I take the voltage.

Looking at your design I see you use a ultra bright LED red, in my design I only use the 3mm LEDs (the two in parallel) because they give a nice voltage drop that helps regulate the power consumption. It seams to me that there is a balance of how much power can I use and how much power is restored in the battery.

Is it possible that the coil is receiving energy from sameplace and recharging the battery?

@Fausto, Groundloop,

I have tried with the following MOSFETs.

IRF510, IRF530, IRFZ44, FQP50N06 and this is what I learned.

All of them will start with drain i.e. running the battery down. Some of these MOSFETs only require a 'touch' of the gate in order to put them into 'charge mode' but some requires more than a touch. The 50N06 requires touching the gate and the drain (tab) simultaneously in order to light up the LEDs. Once lighted up, I'll 'prick' the gate wire with my finger and each time I do that the LEDs will reduce the brightness a tad and hopefully, it goes into 'charge mode'.

My best performer so far is the IRF530. So, I suppose your mileage may vary.....

Cheers, sanmankl

I did not have a 3mm LED but I found one 3mm DUO LED (Red/Green) so I soldered in that LED in parallel.
Now I have a week glow in the ultra bright leds and a week glow in the duo led. My NiMh battery is drained down
to 4,5 Volt. The battery is now so drained that I'm having problems starting the oscillator.
Attached is a drawing with the type number on the LEDs I'm using.

The attached picture is called"Tesla Switch", and, as far as I can see, it isn't a Tesla Switch

I wonder if there is a place in your work for a Tesla Switch which seems to extract radiant energy.
