@btentzer

Regarding your barium ferrite coil (antenna) here is a very nice page that may provide some great ideas.

hi guys,

I made some changes to my setup:

1. changed yellow leds for blue ones (now i get much brighter light)
2. connected circuit to a little dc motor with gear transmission and crank which acts as a generator
so i don't use battery to charge cap any more I just turn handle few times and it starts blinking

cheers,
s.

Bruce,

When you hookup a diode in reverse it can act as a varicap depending on the reverse bias, so you will have resistance and capacitance as well depending.

@ starcruiser

What I actually did was place the diode in the same line on the bread board as the power.  So the power kept flowing, right under it.  A novice's mistake!     LOL

@ All

Testing resistors and looking for results.  I love Plengo's idea.  We need a way to add that idea to this circuit.

Holiday Cheers,
Bruce

That will do it

I have posted in youtube (http://www.youtube.com/watch?v=Gk5VB2g5vOk) another video showing the proof of concept from Tesla 4 switch battery. I think it is very similiar to what this mini-TPU is. If you look at the picture you will notice the coil at the base of the transistor and its emitor.

I left this baby running for over 24 hours now. The starting voltage of the battery was 6.16v. The brightness of the LEDs are 3/4 of its full potential (at least in my perception). If I disconnect the battery it will show a voltage of 6.30v and after one minute it will go to 7+volts.

I think this switch from Tesla/Kromrey really works. Interesting that trying to see the signal on the base of the transistor on an osciloscope seams to be very difficult. Very, very faint signal.

I will also later test the input/output using my new toys: Power Analyser PRO from West Mountain Radio (http://www.westmountainradio.com/Whattmeter.htm) and the Cmputerized Battery Analyser (http://www.westmountainradio.com/CBA_ham.htm). Them I want to see of this will demonstrate OU or not.

Now, here is the resemblance to mini-TPU: look at the transistor in my diagram and what you guys have on the toroid! If we could somehow use a small battery or something similiar it may work. Here is the bad thing: changing the battery with a Cap did not work. Something about the variable impedance or the battery that makes it work!!!


Fausto.

ps: the second battery on the right is NOT connected. It is there just to show the complete "should be" setup.
ps2: photo edited to show correct PNP transistor.
