Bedini replication in Germany

[Ren]

fair enough Zott we did kinda hijack this thread

I guess we should start our own hey.

Look forward to some more pics Albert

Hello,
why didn't you leave your messages in? We want to discuss things...and the replies are hanging in the air without your messages....

well anyway, here are new pictures:

The Batteries:

And a scopeshot....


Ren, I would like to know more about your machine- you seem to have followed the Bedini images exactly. I want to know what your input and output currents might be, and what it looks like on the scope. A shot from the coil side would also be appreciated.
I am not too happy with the performance of the third machine. Perhaps it is the printed circuit boards. I wired them together as shortly as possible, all on the back of the machine. but the wires from the coils have to be longer for this of course.
As you can see on my scope shot,  the "Radiant Spike" is well into the 120-130 Volt region here and goes up twice as high as on the other device. the big batteries charge dead slow nonetheless. RPM is 730 at full speed-one pulse per magnet. I am not sure about the little lamp in the trigger circuit. With it, i get 2.12. A input maximum and without it, about 3 A. Output current is between 800 mA and 1 A. Its clear that a 100 amp hour battery will charge slowly on that. Nonetheless it charges.
For longer test runs, I run at 3 pulses/magnet and about 1.30 A input. 540 RPM on the rotor. I still have vibration problems on this one.

Looks good Albert. I think the pcb boards may restrict performance somewhat. I also think your transistors may be too small for that sort of current draw. It works though so maybe Im wrong. I would be inclined to move towards a mlj transistor.

I havnt wired up mine yet and it still needs a core for the coil, getting that today hopefully.

I am attempting to create a pulsed discharge setup hence the fixed shaft for attachment of timing wheel. I would also like to try a back popping style to keep the primary topped up. So a few different tests to run on the same machine.

Try charging a slightly smaller battery. If your drawing 2.2 amps I would suggest a 40 amp hour battery, thats just under c/20. Are they deep  cycle lead acids? Or damaged? what is vibrating?

@Albert

Just read this thread from start to finish. I haven't been on this board for a while. Great work.

A couple of tips - if you can go to the MJL21194 flat pack transistors, especially if you are running at 24V. Lead acid flooded wet cell deep cycle batteries work better as secondary batteries. You can use your gel cells as primaries if you can keep them charged up with a conventional charger.

@Ren

Haven't heard from you for a while on the other lists. Looks like you're still hard at it! I'd love to catch up and compare setups, I'm in Melbourne too. I'd prefer a Heineken than a VB 

Cheers,

John

Hey John, hows life?

Ive been busy lately, mostly with work. Still building and close to completion. Still monitor other forums, only post when I have something to say. Been studying Tesla patents in an attempt to understand it all lately.
