3 Pole Kit from Rennaissance Meeting

I hear you Kippered
I think you're preaching to the choir on this forum.
I patiently await LaserSaber's step by step vid on the JouleRinger as well as anyone else's on this subject here.
we have had many instances of good luck w/ this tech, and we have one build that puts out more than it takes. however we can not replicate it, so it sits in a box, batteries and all - we dare not touch it until we can replicate and learn how and what we did.
so the hope that someone will be able to teach this is high.

Came across this design while playing with cap-dump circuit ideas on the 3-pole kit, reminded me of the Bedini circuit but with a companion circuit through the looking glass:

Electric Heart!
Electric Fish!
Electric Turtle!
Electric Butterfly!

Designed a PCB for this kit - you want one?

This helped me a bunch. I got a bit frustrated trying to build the circuit on a piece of 1/4" plywood so I looked around and found Pad2Pad - which seems to have decent pricing and tools.
Here is a picture of the PCB I designed for the monopole motor kits:

I contacted RickF about this design and he says he has a design he is working on but it will be a few months before its available. I don't want to wait, and at the same time I don't want to spend a fortune ordering a single board (about $65!) but if I order even just 10 the price/board drops below $10 - so how about people replying to this if they would pay say up to $15 (with shipping) for one of these boards? Then I can have an idea of how many to order to get the cheapest prices and pass them on to you guys. (you would order from me via email later)
The design is for both the old and new kits so you can use either the big transistors or the small ones.
Also I am not an expert on PCB design. It could be that my hole sizes or pad spacings, especially for the potentiometer, are wrong - please review as able. I have also uploaded the .pcb file here which you can use pad2pad.exe to inspect the design. Any comments or suggestions would be great as well before I have this manufactured. (I'll give you about a month from this post date to let me know your interest.)
My design goals were low cost, flexibility with kit components, and clearly labled for easy and unconfusing assembly. It also contains places to put your load LEDs if you like.

Sandy,

That's pretty cool! Wish I had the means to do etching, though I might be able to use Wire Wrap with the image as a template =][

Do you have a way specify bigger traces and special placement/adjacency for components which will be most subject to transient effects and/or high currents?

Also maybe a variant of the PCB layout for center-collector transistors?

That's a nice clean board
it can get a little tricky but once you do a few of these, it gets easier.
very easy if you are using only 3 jumbo MJL's. And, you do not have to worry about the impedance of the board.
