BWJT

very kool! (er)

I would have put things in the wrong places.
Thank you,

PS
What is the actual resistance you have there?
I don't want to buy a pot and maybe I can get close if I try what you used.

jeanna
it really depends on the core you use..
if its a 1'' core from goldmine then i would say 1k resistor with a 0.1uf cap
i don't remember the ma's but it was bright light..
i had 8-10 leds in parallel..
i remember 5 months ago i was looking around some junk i have.. and found a center tap transformer it was a 110v to 12v at 500ma..
i hooked one of these circuits to it with a 9volt battery.. very strange.. haha

good luck

@Kooler and all !

I failed when trying to replicate Kooler's BJT.

Attached are three circuits:

- the one that failed, which is what Kooler suggested in his last post to this thread (Reply #9 on: September 13, 2010, 03:57:17 AM),

- a modified Kooler circuit which worked, but the inductor has no beneficial influence

- and a circuit based on an idea by Groundloop for comparison, where the inductor also has no beneficial influence.

I am not claiming that Kooler's idea does not work, my message is that I could not replicate it.

kooler have you posted the 16ua circuit? i would like to see it if you dont mind.

Conrad,

I could be wrong here, but I believe the inductors are immediately connected to the battery.
It seems to me that in every one of your examples the inductors are connected to something else.

Try to connect the inductor between the emitter and battery without a cap, , also, between the collector coil and the pos of the battery.
I think that is what is happening, or that is what made me interested. Using a series inductor to make a spike from the toroid, but have it right at the battery to influence the charge.

(maybe I am wrong)
I haven't had a chance to try this yet. I think I will need to wind my own 100uH inductors!
