@all

Try it but honestly , that shit don't work , i made 4 of those but fell free to try.

Really?  Crap!  I thought we might be on to something.  I don't mind trying it anyway but it calls for germanium diodes....these are hard to find these days are they not?  I know Radio Shack will probably not have any.

If this works off of radio signals in the air as this fellow suggests, then it seems to me it would be good to have a way of "tuning" to receive whatever frequency is strong in a given area.  I guess the antenna length would be one variable.  I wonder if the tuner out of an old am or fm radio would help?

I really hope this is not another one of those fraud videos we see from time to time.  You know more about this stuff than I do....is there any reason it should work according to the schematic?  Or is it all just a bunch of hooey?  Thanks.

geraimum diode ...  hummm 

i have bout 5 000 diodes ..   i bought up a bunch of radio shack surpluss a while ago

call me stupid ... but are thease the clear ones?  diodes that i can see through if so i have a few hundred of them ... 



ist!

@pirate radio shack has them 1n34a germanium diode, yes they are clear,form what i can see is they work better in the sun, they are photo sensitive. there is inventor3 on you tube that still say it works but really i don't see how i replicated his experiment , got close to nothing.

So Gadgetmall,

i AM RIGHT ALONG WITH YOU  50 T x 50 t  WITH A SECONDARY OF 30 TURNS . WITH TWO TANK CIRCUITS AND A RESISTOR ON THE BASE . .81 MA TOTAL DRAW WITH 4 WHITE LEDS . i WOULD KEEP THE TANK CIRCUIT TAKE YOUR BEST IDEA AND INCREASE THE TURNS  TO YOUR BEST READINGS .

OK, so

You have the 2 tank circuits inline running between the base of the transistor and the coil, do you need both variables?

I am about to see how many turns I can fit on my newer largest toroid. Maybe it is big enough for 100, though I doubt it. Anyway I am mostly wondering about the double tank.

Any advice?


OH YEAH,
@anybody,
this newest biggest toroid says high permeability on it. Is that what we want? or don't want?

thank you,

jeanna
