@ kooler

very nice
did you check your amp draw.. i havn't tried a 3v on the unmodded board

you know the bulb i lit in the video had 356 ohms
and the one you did is 3-4 ohms
i wonder what else we can light...

good job

robbie

The TDK board had blue caps removed. It was hard to measure amps, but they seemed to be aout 400 ma.

It seems to work very well.

it is amazing how the secondary puts out on this..
but i couldn't find the bemf on this circuit....
my whole ideal was to run this circuit with negative energy thru the coil..
and it seem to work..
if you notice the scope showed 4.00 volts on the secondary and lit 9 leds.. i didn't have any more to put in so it might burn more..

Wow good job! Can you please give a more in-depth example of what you mean by negative energy or provide some links?

Thanks!
