Please, when you do in PCB post a picture for us. I am glad you like the little toy. It is fun for me too.

And just for the fun, some still running pictures...

Fausto.

Hi Plengo...
Are you planning to build a bigger version ?? Scaled up for a normal lightbulb...

The topis of this thread is "Self Running Micro TPU, with closed loop."
But I can't see any signs of successfully closed loop TPU:s here.
I'm afraid all of you guys are just running your leds at a very narrow duty cycle and this
requires very low current. But eventually all of your batteries or capacitors are getting drained.
It's more obvious on a capacitor than a battery. It seems to me that the Micro TPU is nothing
more than a self oscillating circuit at very low power consumption.
Perhaps I'm wrong here, but I belive you could accomplish the same timeframe using a
self oscillating 74HC14 logic inverter set to very short duty cycle.

I know where i was on Christmas do you?

     Thanks for the quick replies and the interest.  Ive learned too many times not to pass by the simplest of observations.

Here's an idea, what if you could incorporate a Crystal Radio type setup
to the circuit? Crystal radios have some power but require no input power.

No batteries or anything. And it's tunable. Maybe you can step up the power
using the toroid's your already using. An adjustable capacitor might also work
in tuning in the devices resonant frequency?

Just a couple of thoughts.
