the 2N3440 is a high voltage low current NPN transistor good for
switching
I think pretty soon I'm gonna have to order some Neon bulbs since I
fried them all and now my 3-pole is acting funny. It's gripping the
magnets tight and humming a high frequency tune and the transistors
heat up super fast.
So, I'll just get extra bulb and have them available for you guys,
just in case.
As far as overunity goes, I recommend just getting this unit going,
then figuring out how to tune it (I have detailed instructions) and
then doing the perscribed battery charge and discharge COP
calculations. By that time you'll be ready to put an attachment on the
3-pole which will turn it into a self running unit, this is what I'm
working on. As it stands the primary battery gets drained from running
this machine.
Also, I recommend getting some 12V Sealed Lead Acid Batteries if
possible. You can probably get the smaller/cheaper type.
