Self Running Micro TPU, with closed loop.

Good idea for later but right now I am trying to stay above water, let alone change my life jacket. I think I need a little more time to work this.

But here's another question added to those above.

3) When I look at EMs diagrams 1 to 3, the step 3 shows the led being lit. But since the led is going through the brown coil straight from positive to negative, is'nt the large capacitor the one driving the led directly, and not really through the transistor section?

Hello all,

Perhaps a minor little discovery.  I reversed the transistor, leaving the base the same, but changing the emitter wire to the collector and the collector wire to the emitter.  It made the LED much brighter, and doubled the run time. 

EM or Duff, perhaps you can try this and verify.  Thank you.

Cheers,
Bruce

Is very nice experiment, in an other post you tell that the LED blinked 4 minutes and 36 seconds, the blinking time is cange ?

Is it possible make this simple test:

Replace the condenser from 1000 mF with a smaller, for instance 500 mF, so that to verify if it varies the duration of operation on the device and than it varies.
The test can be repeated reducing the condenser more and more.
Is possible to repeat the test with a bigger condenser.

With this test it is possible to clarify the origin of the energy of operation, if the time of operation tightly depends on the consenser capacity, it is evident that the condenser from 1000mF plays a fundamental role. Otherwise it is very probable that energy comes indeed produced by the spool.

I will try that when I have more caps.  I only have 1000 uf electrolytics that I bought for this experimental circuit and a ton of tiny ceramic caps that I had.

What I have just done is put two transistors in parallel, hooked up the original way that EM drew the circuit.  My time is at 8min 19 sec. and still going.  Wattsup had this idea and posted it earlier.

I will post the final time.

Cheers,
Bruce

EDIT:  I miswrote, I have both transistors hooked up OPPOSITE the way drawn on the schematic.  I am at 12 minutes 18 seconds and still going.

2nd EDIT:  15 minutes 30 seconds and still going...

LAST EDIT:  Final time 18 minutes 3 seconds.

Yet another member I and many others will never trust or take seriously again.

If anyone else is considering a hoax to prove a point, try calling the topic something like "How easy it is to fake a TPU"
This might actually be productive. Otherwise, please don't bother. Every day the current power brokers of this world are in power is another day one of my brothers is murdered in wars for oil, another day our home on this planet is raped, another day a family member is diagnosed with an incurable disease caused by environmental toxins.
Nice job.

Pardon my venting
