Yes i always have ran it at 9 volts and have ran it for more the 2 hours at 9 volts powering a tube and a least 50 leds via wireless or SEC works perfect and never had an issue.

Thanks.

I think that the cell phone charger is providing about 200 mA at 5 volts (1 watt). The TDK board requires 1 watt. So there is just enough power. Note, that I could not power the modified TDK board with the cell phone charger because it required more input power to work. My best single coil JT only puts out about 1/8 th watt, but it is able to increase the voltage to over 1000 volts. Each circuit has advantages and disadvantages, you need to pick the appropriate circuit for what you want to do.

Please post more info on your wireless test results.

Dark pic I know but this is from my wireless pick up from the tdk. Working on running a JT I am reading over 5 volts!

WOW

16  micro amps

You could probable power that with an am radio circuit.

Very nice, kudoos indeed.

This is a great idea using the path from the emitter to the toroid, allows further harnessing of the EMF present in that area of the circuit.

Thanks. What were the distances?

This is a wireless project I am working on that is using the TDK board. I am only getting about 5" so far.

hey
i should have said something sooner but if you put a inductor between the two emitter wires it make it alot more adjustable and more powerfull..
i built this circuit trying to improve the gadgetmall design.. only to find the secondary is more powerfull than the
c-e connection and i think we can light jeanna's loa bulbs with alot less ma's..
i want to thank you for duplicating this..
