Joule Thief

[jeanna]

@xee,
What about when it WAS working (I assume the 2AAA gave it what it needed since they turned on the bjtl -- they certainly gave it the current it needed. The proof is that it went on) and there was absolutely nothing at the secondary. A secondary that is very strong with the 3904.

@ AK...re: your Tesla Doc.

Thank you...that was very enlightening.

"The primary circuit's frequency is determined by the frequency and voltage of the source "

Would the joule thief be suitable 'source' in its present stage, or are more amps needed ?

I will let AK answer you also, but I can say I tried it. It is what I used to turn on my 2 Tier circuit. It made the second joule thief work without any additional transistor. The pulses from this as source were able to turn on another joule thief.

If you have been following you might remember other more exciting things followed.

Hey Jeanna,

You guys are hard to keep up with...between that and the Black Hawks on TV while I am catching up is affecting my attention span.

In case you didn't know...the last time they won the cup was in 1961...and they are close again for the first time since 1992.

I even plan on giving the screen a good cleaning if they reach the finals, so you know its big.

So needless to say I am a little distracted at times.

I do recall your 2 T j/t though.

I hadn't considered your application yet...I was just theorizing more along the lines of the single j/t providing the amplified voltage to the Tesla air coil transformer.

Your double toroid advancement would probably have dawned on me somewhere down the road.

I must say, you guys are in danger of doing significant things the way you're going about things.

Regards...

Cap:

I love the way you put this......

I agree 100%
