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

[Grumpy]

"otto" has had success.

Dave shared all that he has.  Simple enough to follow.

Turbo took a more direct approach, the direct route.

Hi Mrl,
Yes but I would drive a MOSFET from the TPS2812.

I have just found a ICM7556IPD in component box.
I will try this device out if its not blown.

I would like to take the direct route also but I don't think I could duplicate Turbo's work from the information posted here. (maybe I missed something?)You seem to be following in his footsteps, do you have additional info not posted here? Any help would be greatly appreciated.

I copied everything that Turbo posted right after all of the talk about shockwaves came out - this was started by someone mentioning ultrasonic flight - this led to Tesla's RE.  Turbo made some very good comments and then posted his work shortly afterward.

His comments and manerisms were not that of a "faked display".

After wasting effort on the mysterious 3 frequencies - I took the RE clues along with several others, re-embraced the shockwave talks, and formulated a concept of what Turbo had shown.

It all boiled down to this:

very short positive pulses - no reversal (might trigger a mosfet with a UJT relaxation oscillator - very simple - hell I'm going to try that - could just use cap and resistor relaxation circuit with suitable load)

Turbo's red wire may be a signal from the oscillator that he mentioned or static DC - I do not know yet.  Marinov mentioned that having a static field prevented the field from relaxing - I'll try both.

Wow! There sure is a lot of discussion on drivers here anymore. I searched down X's 8038's  and the rest of the components that I didn't have so that I could build the generator that he showed in his PDF file. I ordered and paid for the parts about 2 days before he came back and said that the circuit wasn't stable enough. I can't blame him as he didn't know at the time or I am sure he wouldn't of posted it. At least he said it wasn't good enough and it will save me time in building it.

I have been watching this thread carefully to see what IC setup would be best for this project. I guess it is pretty hard to come up with a consensus when you have multiple professionals with different backgrounds working on it. Hell, I can't even get my wife to agree with me and she's not even a P.Eng.

Anyways, I decided to try what we were told to do first. Try it with tube/valve generator first. So, I went to Ebay and purchased 3 old tube sine/square wave generators. I just bought the last one tonight. Hopefully, I will have something to show in the new year.

P.S. If anybody wants some ICL8038's PM me.
