Hi Guys,

Well I'm not having much luck with this... I had a transistor circuit all wired and soldered but soon blew all the transistors... I think neons might be a good idea with this circuit as well

Ran out of transistors so I set up a test rig to see how well it works in principle. I know this isn't the original circuit so I shouldn't expect the same results from it though I am still disappointed with the results so far.

This is the schematic for my test rig... there are 6 switches (if you ignore the bottom one). three are marked "a" and the other three are marked "b".

When "a" is open "b" is closed and vice versa so the capacitor pairs can be switched from series to parallel.

The bottom switch (marked "c") is actually 2 loose wire ends.

First I charge all the capacitors (12.78v - ish) and then very very breifly touch the wire ends together and then measured the voltage of the capacitors. Then I flipped the switches to reverse the circuit and repeated.

I tried it with three different coils (air core, iron filing core, bifilar) though the results were pretty much the same. I have also tried it without the diodes. I just added those as an after thought for the flyback voltage.

looks a bit of a mess with all the wires but this was just for preliminary tests.

the caps were 4 x 10,000mf rated at 63v each

Without the diodes in the circuit there would be a very pretty blue spark when I touched the wires together which wasn't present with the diodes.

Here is an example of the results

12.81 + 12.80 + 12.76 + 12.74 = 51.11v

12.48 + 12.44 + 12.92 + 12.91 = 50.75v

14.07 + 14.06 + 9.59 + 9.54 = 47.26v

12.35 + 12.28 + 10.54 + 10.54 = 44.87v

11.08 + 11.01 + 10.60 + 10.60 = 43.29v

11.45 + 11.45 + 9.59 + 9.57 = 42.06v

11.15 + 11.14 + 9.73 + 9.72 = 41.74v

This was using a single filar air core coil without the diodes in the circuit, though the results were pretty similar with every variation.

I have heard of a couple of successful replications and so I am not put off by this rocky start. Any input is appreciated so I can take this forward. Perhaps it requires instant swapping of the batteries... i don't know...

I played with it with transistors but couldn't get it to do anything other than loose.
I am trying it mechanically. So far just switching and collecting from 2 single batteries shows good results do the spikes. No charging of batteries yet but definant recycling of current.
The next phase I am switching between series and parrallel. The motor starts pulses out of the series batts at 24v then we discharge the coil into a parrellel set of batteries then reverse the proccess. We are using a camshaft and points from an older car to setup the circiut and fire it.

If its named according to its inventor thats what he would have to do. Mechanically that is.

Good luck
Matt

Use a 4pdt relay and wire the coil to one of the normaly closed contacts and the other side of the coil to ground. This will cause the relay to oscillate. Use the other three to do the switching. The smaller the relay the faster it will oscillate. Ken Moore had a diagram in the Eike Mueller report he did with Tom Bearden and John Bedini. Somebody put a copy of it on this board a while back.

That is VERY clever! Will definatly give that a go Cheers!
