Joule Thief

Goldmine has a package deal where you get 10 of these boards for $5.00 (US), fifty cents/board.  I just ordered 10 more boards.

What a deal that is.

Hi there, I am a big fan of this thread - currently up to about page 300 odd - bookmarked on my laptop. Amazing source of information that gave me the will to make my own flash joule thief.

I'm not trying to step on anyone's toes here but I've made a website about the joule thief - http://joulethiefcircuit.com .

So far I have just given a basic overview of how it works, a picture of the stock JT schematic, a link to this thread:)

I know this forum is one of the main sources for JT & other energy device research but if anyone here wants somewhere personal to talk/blog about their experiments, theories & research - you are welcome to have a blog/page type thing at joulethiefcircuit.com.

I will support this website by putting a advertisement on mine.

Once again, this is an amazing source of information. Thank you, all the best & keep it up.
Hopefully I'll catch up one day

G'day Bill,
Just thought I'd drop and see how you were going. Always good to see lotsa progress.
I'm not dead yet LOL and still boiling up crystals. Latest effort sitting in front of me at work.
I'm modifying a JT to act as an exciter for a crystal cell but achieving resonance with the matrix is a bit tricky.
Anyway good to see you are all doing fine.

Ian:

It is great to see you again.  How is your crystal cell research going?  I am still messing around with building little lights.  Hopefully, they will be good for something someday, ha ha.

If you have a link to where your crystal cell work is going on, I would like to see that.

Take care,

Bill

Another JT light made using an LED bulb made by Phillips.  This bulb was expensive and the light output from the mains was not that great.  So, I gutted the bulb, mounted another surplus flash circuit in a box and placed a small mustard jar over the LED.  It is brighter now then when driven by the mains and their driver circuit.

I just got a great CREE 800 Lumen LED bulb and I love it.  I will be converting all of my house light bulbs to these.  I will make a video of them soon.
