Joule Thief

I am not sure which way A go. Just reverse one set of leads if it does not work. I have not measured current but it is high. I gave up using phone charger because the batteries would only last less than 1/2 hour.

Nice job Xee2.

But you need to make a bigger L1 coil.The L1 coil I'm using is 3.25" diameter x 14" long 23ga. mag wire 4.80mH.
You should also make the L2 adjustable so you can move it up or down the L1 coil to find the sweat spot.
The L2 coil I'm using is a pancake coil 21ga. plastic coated wire 9 turns .05mH

Thanks for the info. This was just to see if I could get something to work. I will try some other coils. I also need to experiment with field detectors and this will allow me to do that.

I was able to light a fluorescent tube wirelessly using slayer007 circuit. But tube ends need to be less than an inch from the metal plates.

Good job xee2!!!!! I have been so busy with work I have not had anytime to post pics. I switched over to using a different transformer and will post some pics tonight or this weekend.

Take care,

I wanted to post a new picture fixing my old picture so I didn't lead anyone astray. This is the one you said would work (and wouldn't blow up capacitors) yes?

Your picture looks  great except  for one thing.
JTs don't provide high amperage  output

I don't  think  think that as a group that  we  have ever came up with  a description or name for their output.
Maybe the  best description is  that it is spikey
It is my opinion that  the spikes  are a mini version of what  Tesla called a disruptive discharge.
In  the circuit that you have drawn  the LEDs are lit up  by the spikes......not by  normal current .

About blowing up  your cap .

This  circuit  will not  blow  them up with normal operation .......but  it can  blow them up  by building up to much  voltage.
So watch  it closely ........or make  a voltage limiting  circuit  of some kind

oh forgot to mention it is running on 0.80 ma's
