@ everyone

this is simple and i have decided to help as it seams you all can use it

the coil does not matter 50 turns that is all  make it short make it fat it does not matter the collector wire throught it agin it does not matter to a degree

the reasion im going to answer some of your simple questions is

it seams no one elese wants to step up

i will answer what i can as i have no scope but i have a verry good handle on this

otto is a busy guy and i will be helping him to the best of my skills

i was going to edit and repair my posts but i like it the way it is i may fix some that make me feel good but not many

a pic of what i posted with ottos test. wire it up as in his drawing

i used nothing to drive it but a 12v  dc adaptor  and manualy plused it and i hooked up my volt meter and as the pic shows the voltage increased by .20 volts or so in this test i used speeker wire and magwire as you can see  so when you hit the right freq for the size of coil it will ring and make the kicks

IS TEAM!!

@Otto, I recommend that you bring your pulse width way down from 50%. You can get better radiant results that way and use much less current from your power supply. Just a thought.

My second mis-replication of Otto's little coil on the Lords of the Ring topic agrees with you.  I was sweeping the pulse-width when I found the sweet spot.  Post frequency adjustments did not seem to move me out of this sweet spot, as I recall.

EDIT ONE: I just checked, post frequency adjustments did not move me out of this sweet spot.  In fact they seem to have little effect on frequency at all.

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.)

Just confirming this for you!

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?

Very good info on the variation of pulse width.  Otto showed a square wave.  what if you use another waveform?  What if you clip the wave , or clamp it, or differentiate it?  What if you use positive and negative signals?

I'm not bashing or flaming either, but a voltage increase and a brighter bulb is not enough to say you have something extrordinary.  No current measurements, no variations of the circuit - what if the lamp wire is outside the coil, across the coil, or far away from the coil? What if the lamp wire is ran through the coil - bifilar canceling?

Don't give me that "I am a simple person - I'm not an engineer" crap either - seek to understand what is happening - look at it from several angles - confirm your theories.

I will try to get it right this time.

The test a step towards understanding ...you will have to actually do it..Im sorry that I have to say that but surley ,at some point there will be something incomprehensible to you..because TPU's are impossible  right?
Please allow that some effects are not documented and are not in theory YET


Now bear with me  here, Please it is important.

Your first introduction to maths was not long division right?

Why not? You could count already..?


Those that actually do the test Might be on the same page.and ready for the next steps.
Otherwise there will  be misunderstandings.
I am not going to say "do the test again" and it is the last mention of it from me.
I am glad that some are actually doing it good for you!
Th onus of proof is not on the supplier of information..the ous is on you to do the simple experiment. Or not..please do not ask poeople to do things that you can do your self..it just shows that you have not done the test and it saddens me .

Im sure that there may be other ways to learn tpu art..its just not here right now.

I will bow out for a bit as If this has not made the situation more clear then it may be beyond my ability to convey it.

Take care of each other
