Self Running Micro TPU, with closed loop.

the thinner wire is at the base of the transistor.

Thought so.  Thanks again, plengo. 

The coil is  air core  wound on a spool.

I am confused.  What about the bolt in this image;

did you insert this after winding your wires on a hollow spool?

Oh, and did you twist your wires together before winding them on the spool?

It looks like you have inspired folks here to test your design.  Why else would we be asking so many specific questions.  Thank you for keeping up with us.

@Plengo

Is very important that you public a table with battery tension and time, in this way is possible to do a cleary evalutation of the real system performance.

not very professional but I have these numbers but no timeframe - 6.16, 6.80, 717, 5.83, 5.78, 6.11, 5.64, 5.91, 5.63, 5.68, 5.73. Those numbers are since when I posted the first version. When the number get high I tried different designs including the one on the last picture. Than I put it back to the best version (number 5.64 and on).

I will start tomorow a new test with a real computerized power load tester (Power Analyzer Pro from WestRadio). This way I will be able to publish the real data sample collected to everyones scrutinity.

@Rosphere
I think you are looking at the wrong coil. That coil is from another older experiment. For this pictures that I posted I use the coil on this new picture below.
Look at this video: http://www.youtube.com/watch?v=Gk5VB2g5vOk


Fausto.

ps: Second picture is the running circuit. Dont pay much attention to the mess of wires and extra components not in use. Most of the wires are to connect to the osciloscope and two multimeters that I use. I keep all off and only turn them on when I need to take measurements. I also replace some of the LEDs with new white 15000mcd LEDs and removed 2 other ones.

Notice on the gate of the mosfet (the one on the bottom) a red wire that I use to touch with my fingers to get the transitor on the top to oscilate to the correct frequency. It is necessary to touch many times until the right brightness and energy consumption happens otherwise it will only drain the battery. Yes I know, it is a little trickier than you think to get this baby running just right. But that science isn't it?
