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

You can believe that capacitative coupling crap if you want.  Turbo understood what he was after and achieved it.  Until everyone acused him of trickery and then his identity was exposed, he was telling you all about radiant energy.


As for winding of the coils - who cares?  If you are not kicking them right then it makes no difference - just a roll of wire and sore fingers.

Rob,

Yes! :-) I have a O-scope. I also said in a post that I got much of the same osc. mixed signals as Dave did. Remember?

I have not had any failures!  My circuit worked perfect the first time I switched it on. It was the TPU method that failed.

Alex.

Hi Alex,
you were the one with the professional done PCB board with the 3 x 555 timers.

With waht current pulses did you drive the coils ?

What frequencies did you try and what were the exact waveforms ?
Maybe you can post a few scopeshots of what you have done ?

Many thanks.

Regards, Stefan.

Guys,

Here is a schematic I found on the net ( http://home1.gte.net/res0658s/fatman/4046pll.html) that can be modified with a little work that will provide a frequency multiplier to do our bidding.

The VCO source can be a 555 circuit, a AD654 VCO chip (I included the spec sheet) or your favorite signal generator. This circuit will give us a stable 3 frequency (or more) outputs from a single oscillator source.

My issue has been getting the 3 frequencies to line up properly due to drift of the 3 seperate osc. So this one looks relativly cheap and should give us what we need.

Highlites:

multiple harmonic outputs

included mixer (if you want to try it that way)

PLL source (for stability)

can be modded to provide other harmonics

Squarewave output.

Micropower consumption  (should be able to run this off a 9vdc source)

Check it out it might help you.

Merry Chirstmas to all!
