@Eldarion

This is EXACTLY what I found!  As soon as I decreased the pulse width to less than 10% (I have a custom crystal-controlled pulse generator that can generate an exact frequency with an exact duty cycle) the MOSFET stopped heating up and the light was as bright as it was without the oscillator connected.  (On my setup, as soon as I turned on the oscillator the light actually dimmed.)

Eldarion, I'm not bashing or flaming... but maybe you can elaborate on if the Oscillator was not connected, then it would not heat up... So reading between the lines you got the unit started with 10% less pulse width, then .... disconnected it and the tpu continued on it's own? Thus sustaining itself?

Art,

No offense taken.

If this thing was sustaining itself, I would be shouting it from the mountaintops, not making one little post and dropping it!   There is another source of power in Otto's diagram (the 12V source); that is what is lighting the bulb when the oscillator is disconnected.

Sorry for the confusion!  I will continue to experiment with this stuff, and if I find something noteworthy I will post explicit instructions on how to achieve the effect.

Hello all,

@Jason,

I already know about pulse width. Come on guys, Im working without a break.

When you change the pulse width you get bigger kicks....  I dont have to change my pulse width!!!

Yes, Jason youre right when you say the kicks are changing into sine waves, yes.

To all,

I have a question for all of you: why are you all trying to get sooooooo big kicks?
What will you do with so huge kicks???
I can make kicks that can blow my oscilloskop and then what???
You mean if you have mega kicks you would have mega power???

Eldarion, place a small cap from Gate to Source pins.
Tap the frequency gennie to give the circuit one pulse to start oscillation.

You might have to play around with cap values a bit to get it to sustain oscillation.

Enjoy

Jason's kicks are no bigger than your Otto.

He was inspired by you, and accidentally found another way.

I see no reason for vitriolic responses. And labels, as you have done in your new thread. We're all trying for the same thing. Are we not?

I think that Otto is trying to make a point.

7 months ago he asked us to do his little test..

He is raising the questions because there are answers.

He knows how hard it is to get points across and is learning to be a teacher.

His primary language is not English
