New Jewel Thief "Resonate LCR Circuit" Much less energy draw....

[sirmikey1]

Hi Guys,

   Slayer sent me a link to purchase the little cell phone charger joule thief thingy. This is one of the better ones, comes with 12 adapters. 

Slayer Recommended buy two and running them together 12volts...

sirmikey1:

Thanks, that is a great price for those.

sirmikey1, the transistor base, unless it has been severed and insulated, will pick up transient voltage transmissions from the other part of the circuit, even though it appears 'loose' it's still there.

If you try the circuit, try insulating the base lead, with a bit of electrical tape or shrink tube you may notice it stops working as well.

... Tried the  car coil; takes the AA battery out fast. 

    @jeanna; Agreed, hard to compare.  The JT, the BEMF, would think that every flashlight and portable electrical device on the market would soon have one of these.  $...   Chilliqueen NPN never hot with right resistor.  Open circuits, CQ may outrun the JT.  How long before science catches up to this stuff? 


  Meyers forbid resistors/shorting, used chokes instead...   Anyone tried triggering the transistor base with a choke instead of resistance?  That and/or maybe an ultra sensitive NPN base? 

sirmikey,
These are very interesting ideas.
Is a germanium transistor really that available?
It only needs 0.3v to start,
I like the idea of a choke to start it. It is in the arena of the mag amp, which I try to get started on every once in a while, but never get very far, because it seems to need a pulsed power source....

About the amps draw, I think that whatever you find out for amps draw needs to be backed up with how long it takes to drain an AAA battery. And I tend to believe that you have just shown this to yourself.

...And anyway,  if anything can run on less than 1 volt then even my EB can run it and it doesn't matter about battery life.

It was a pm from cq about the overheating, and I never went anywhere with it except to note it.
Because it exceeds my personal limit of 1 transistor, anyway.
If I ever were to make one of them, I would only do it one time out of curiosity.

thank you,

jeanna

This will run on less than 1 volt and I am sure your EB will supply enough current to run it. You may want to change 2M resistor to lower value to increase brightness of LEDs.
