user TURBO?s replication of Steven Mark?s TPU ?

[CTG Labs]

Current input is not relevant here.  Some of the devices had one or 2 9v batterys in to power the oscillators and later some were start by a few swipes of a magnet because certain investors couldnt see how the the bulbs couldnt be powered for that long by a 9v battery alone, all they could see was "well, it has a battery running it so whats so special".  Ignorance is bliss!

The key is the right mix, pumping high current in is not the answer, it implys magnetic induction where none can take place.  The key is the right mix and then the feedback.

Hi Alex,
with my TPU tests with the 0.47 uF cap in parallel at the collector coil output
I got about 80 to 90 % of the input at the output I would say.

And I used only milliwatts to drive the control coils...
so next time I have time to experiment with it,
I will try to drive it with at least 5 Watts per
control coil to see, what is coming out...

But if nobody sells me a 3x frequency square wave generator,
I have to build it myself, which costs more time to complete..

Regards, Stefan.

Stefan check out that circuit I posted, if your gonna build a frequency generator for testing a TPU this may be the way to go instead.


BTW, Merry Christmas!
