Joule Thief

Paul,
I have suggested this before, but maybe you didn't hear it.
I assume you are using firefox with adblock turned on, because those ads take a long time to load each page.
Beyond that go to your profile page and find the setting that changes the number of posts per page.
Mine is set to 50 posts per page, and it really helps. It is one page instead of 5.

It is up to you, of course.

@ Paul:

I agree with MK1 and Jeanna...the first 150 or so will give you a good solid foundation on our progression here.  I believe I made it up to about page 600 in the Joule Thief diagrams topic where I posted the schematics and referenced the page they were posted on in this topic.  But, I will say that, since things were progressing so fast, some of those may be outdated now by newer and improved circuits.

I went back the other day and read the first 50 pages over again (I guess I was bored and could not sleep) and I was amazed at how far everyone on here has come in that short time.

Gadget,

Would you please help me with the thermostat thing?

I see it is a switch.
Is it a standard switch I can buy at the hardware store?
I think it is unusual voltage, and I bet it has more than 2 wires in it??

thank you,
I am so glad you saw this!!!!!

We can have that cuppa tea soon.

Great Paul!

I am so glad it has helped.

Jeanna it can be several types of switches . I like the Bi metal contact . it can also be a thremal cutoff . you can find these in almost and device that heats . hairdryers , irons dryers . Its a matter of just moving it closer or further away for these and as far as the bi metal you just bend the metal to meet the heat needs . I hope this helps . There is also the old thermostat that have a tilt mercury switch in them so when a given temperature is reached it tilts the mercury and either breaks or makes the connection . agree THIS IS VERY HIGH AMPERAGE AND
THERMAL CUTOUTs are probable what  i will use other  wise i just use a switch

@paul thank you for your Interest . If your replicating then fine .I think thought you need to start on page 1 or go to evilmadscientist.com  and learn how to make one there before drafting up someone elses work ..

I will re-post this here:

This is what I used to make my first working basic joule thief.  Very good, clear instructions.  The Evil Mad Scientist labs version was fine except, they were not clear, at least to me, on tying the two end wires together from the bifilar winding.

The corrected circuit is here.
