really?

i have a few fugies... i will find them and take a pic

let me know if you modded the one i have ....

thanks gadget...

ist!

just finally got the mk2 6 divider mounted ..  i may cut back on the recharge batteries ...  so they charge higher and quicker ... might just have 2 of them insted of 4

i was thinking of adding a tiny jt as a indicator light 1 for each input  battery ...  and mounting the switch and indicator light jt on the other side of the supply battery ...

ok

Thanks guys for the information on the transistors, much appreciated.

@ Gadget

I don't doubt that all of what you say is true, in my case however, no go.

The CFLs are different wattage and without the circuits from 5 to 65 Watts equivalent but the only way they light is using the circuit mod from josepino.com which isn't worth it as it drains the battery too fast.  I doubt there's any difference in the CFL gasses wether they are from US or Canada.

So the next step for me is to take the components to a separate breadboard and start over one component at a time 

It probably doesn't help that my hands are too big for the Fuji cct, my index finger covers over half the board!!!  But I did manage to solder the connections as neatly as possible and checked for shorts which there were none so I have no idea why it isn't working out for me.
I know we discussed the transistors before but even the board with the 2SD1960 transistor didn't work, I tried with just the potentiometer and with or without the caps so I don't know what's going on.

Anyways, thanks for the input.

Regards,
Paul

Not sure if anyone else has tried nanocarbonised paper to transmit energy it works well but it wouldn't make my JT light!  Has anybody tried this or know why it wont work?

@all,

Sorry, i think the discussion was briefly turned to coil over coil - but there is another three wire setup out there.  In any event, the thread has leaped two pages ahead so no worries.

My bridged version was working right, but then went out over night.  It may be the result of using a dead battery .

In any event, all the designs I've posted recently work.  Now - it's on to larger things, CFLs or Neons.
