Overunity motor, part3, all 4 recharging bats reading at 1.400 volts now.

On mine, I get a doubling of voltage at the Collector with no LED load, from 6 volts peak with LED to 12 volts peak without the LED. This is with about 1.5 volts at both supply sources. I still have the 220R resistor in place. With the resistor shorted I see very little change.

Going from one to four LEDs to open circuit with the 120 Ohm resistor:

1 LED 4.88V peak, 2 LEDs 6.96V peak, 3 LEDs 9.04V peak, 4 LEDs 11.1V peak, open 19.2V peak.

With the base resistor shorted, the open voltage increased to 22.2V peak. 

I went back and retested with the 1812 chokes and found that the circuit will oscillate with those like the others given a kick to start.  I short the collector to emitter with tweezers to genrate the kick.

The one difference may be that the probe I am using on the collector is one of the 20X probes our mutual friend made up for me.  It has pretty light capacitive loading.  This is all running from 1.3V for the source battery B2.  The recharging battery B1 was about 1.2V for all the tests with an LED.

It would be great to see at what efficiency the device is running at.
I must say Mark,i am most happy that you are experimenting with this setup.

Thanks

Do you have a darlington transistor you could try-i have none ATM. Just interested in what may happen?.

I tried a TIP-102.  I could not get it to start.  The base - emitter resistors are likely damping out the tank.  I did manage to find a 2N3055 in my junk box.  It runs much slower than the 2N2222A which is quite understandable given the lower gain.

The efficiency is very low, around 1.2%:  2N2222A circuit 0 Ohms base resistor, 2 shielded 1mH 2.9 Ohm inductors:  4.2uA average current into two red LEDs in series and 1.3V average voltage for 5.5uW output, versus 1.29V in at 153uA for 458uW input.
