I am sorry I have to ask this but, Do you really have a working device or is GK just blowing off at the mouth again?

It would be great if there is something out there or at least some progress in the right direction.
Hat's off to all involved (I hope)

Hello All,

GK was right. We did all work together tonight and we accomplished a lot. But just to be thurough, I have documented, in detail, the simple circuit I ?accidentally? discovered tonight while playing with Otto?s circuit setup. I have attached photos of the actual setup along with scope shots and a circuit diagram for your replication pleasure.

What I basically discovered is a way to make the IRF840 MOSFET switch itself on and off in a circuit without the need for a constant input frequency!

This happened when I was playing with the gate of the MOSFET in my rendition of Otto?s circuit. He had the output of the frequency generator going straight to the gate of the MOSFET. Traditionally, a small resistor is usually placed there to drain off some of the charge so that the gate can properly be switched on and off. So I simply grabbed a 2KOhm resistor that I had handy and slapped it onto the gate. Unfortunately, the function generator I was using couldn?t pulse the gate hard enough to switch the FET on fast, so I went for a smaller, 200 Ohm resistor instead. When this didn?t work, I had a thought to grab a random capacitor and place this between the Gate and the Source pins. When I fired up the circuit, the MOSFET immediately raced up into the MHz range, and I saw these ginormous spikes showing up on the screen. But I was further delighted when I shut off the function generator and the MOSFET condinued to switch completely on it?s own!

I even completely disconnected the leads from the function gen and the circuit continued to sing happily away?. This was the start off all that GK mentioned above? I?ll give more details about those tests some other time since it is 4:32AM and I haven?t gone to bed yet .

But just think! With the proper tuning, we can create the frequencies we need in our TPUs without the need for 555s or function gens! Just a simple Cap and tuned coil is all you need!

I need to make one quick note about the circuit diagram posted below. You don?t need to use a cap at all across the main pulse coil. I just used it because I could, but you at least need a segment of wire there so that the BEMF from the coil will circulate when the MOSFET is switched off. THIS IS IMPORTANT or else it will not work!

To start the circuit, you merely apply a single pulse to charge the gate. Once this happens, it will immediately take off by itself! Don?t believe me. Try it for yourself! You will be quite amazed at the result!

God Bless,

P.S. There are some other interesting factors about this circuit that you will notice after running it too .

EDIT: Fixed the circuit diagram, which was drawn incorrectly

Thanks for having me there for this. I'm not sure how much I contributed, but It was thrilling night of discovery. Very exciting indeed.

To be fair, I still think we need to reproduce Ronotte's experiments in order to suss out what's going on, he's got some very promising and exciting results as well.

SM said there could be many ways to wire these things up, and it seems the universe is lining up right now, and giving several people results at the same time.

Oh, and no coast to coast AM stories. I have to agree with Mannix that that would not be a prudent maneuver.

Also, GK, I have to say, you seem a lot saner when I'm actually talking to you (not to single you out or anything, we're all a bit nutty). Seems much of the silly you put on is just in your posts, I'm glad to have worked with you last night, and everyone else, nice to have met you and worked with you. Hope to do it again soon.

Rich.

if i could add ......

this is the device of a 1000 styles

@ everyone who has not  DO OTTO'S TEST so you  can move on to the next step

the "GAME"  is .....

right hear this thred LOTR  read and reread agin until you understand

@ all the thinkers out there PLEASE PLAY THE GAME


one more thing LET US ALL THANK HIM

@ Rich.Nice to work with you too .

@All. Be careful doing any of this. It can get real bad real quick! To those who know you know to those who dont, dont mess with it.

@Ronnotte,

will you Come play with us? Your sand box or ours?
