Tricoiler, are you trying the french pat?

i am replicating this one using wood instead of plexi.

but i only have 3 coil mounts made and enough wire for 3 coils instead of six.
all my others have been pretty sloppy and ugly, rollerblade wheel for rotor, bike wheel for rotor, no real adjustment on coil to rotor gap, etc. i need a better platform than that to do tests from.

@ MK1:

Yes, there are many way to jumpstart this thing I believe.  I was even thinking of precharging a cap to 1.5 vdc or so and going from there.  That should run the JT circuit without stressing the transistor and heck, if we need heavier duty transistors to do this...I will get them.

@ Wilby:

Hey, I really appreciate your saying what you did about the 2 floro tubes but it is not necessary.  At about the same time you said that, if you told me you could light 400 leds with an AA battery I would have (politely) said you were full of crap. Ha ha.  We are evolving here and what might seem crazy one week, someone does the next and we keep having to raise the bar.  I believe this is a good thing.  As for the 265,000 MCD LEDs, electronics goldmine has them for a little over $2.00 each.  You will not believe how bright they are.  They are the large 10mm size and I think I read on their site that they are actually made with 4 chips.  They don't appear to draw much more juice than my other "ultrabright" 10mm leds which are rated at 2,600 MCD.

For about $3.00 bucks, I can get a solar cell at electronics goldmine that is about (if I remember right) 1.3 vdc and 1 amp output.  My question is this......will that 1 amp fry my caps or transistor?  I doubt the leds will drive it at 100% anyway but.......would I be better to get a cell with lower amp rating?

I want to order this stuff tomorrow.....I can't wait.  check out those high output leds, they were on special when I ordered some last week.

@bill
i think the 1.3v 1amp solar cell should be fine. it shouldn't fry your cap and the transistor should be 'protected' by the base resistor.
2 bucks... i might just go order me some of those.

I see bediniesque , Very good , every one seems to be missing how much more that charging battery this thing dose. Its also free movement
maybe 1/10 actually use it. I am completing one my self , lets say the pickup coils (30 selenoid coils stator) on a ssg fan rotor 10 magnets n/s stator up and under the disc , it gives me about 12 volts per selenoid coil on a 9 volt load.

I cant wait to share pictures with you guys.

@ Wilby and all:

Below are some links.  The 265,000 MCD LEDs are still on special!!!

http://www.goldmine-elec-products.com/specials.asp  About halfway down the page....265,000 MCD LEDs

http://www.goldmine-elec-products.com/prodinfo.asp?number=G14741 .5 volt 1 amp solar cell $2.49 ea.  I was wrong, I would have to get 3 of these but....so what?

I am going to try this!!!!!!!  Wilby, thanks for the info about the 1 amp and the transistors.
