Joule Thief

[jeanna]

Gadgetmail, I rated it and commented. I finally got through. I guess I had clicked deny one too many times to youtube cookies --- and gmail too. I found it. OK on both counts. what a trip.

@Bill, don't you have a very IN focus pic of the fuji circuit that gadgetmail could use to show the place where he added the cap?

I just cannot see it. I haven't pulled out my fuji boards for more than a half hour, I admit. I am seriously trying to do this with the little toroid, but, I am sure I will learn a lot by getting the fuji board figured out. That is why I am asking.

@GM if Bill doesn't have a good in focus shot of the part you modified, I will take a pic with the xo cuz the pics from that xo are really good. Please, I am still not sure of the cap placement on that transformer.

(I loved your video.)
thanks,

I wound another toroid today.
The joule thief was the same but the pickup coil I made biger.
This one was eight layers thick.

I didn't make a video of it but it does light the cfl a lot brighter.
So I guess you should try to make your pickup coil as big as you can.

Jeanna:

You mean these?  This was before I cut the diode and also mounted my other lead to the pin on the transformer and the trigger coil.  I think these are the most clear shots I have though.

Here is one after my other modification.  This should be better.

@ all the world.

Bush Fire toll in Australia is at 181 dead and climbing, Police Commissioner said there were about another 15 bodies, she said the coroner has been advised to have at least 300 places avaliable, awful this.

They found a hall filled with bodies, several towns been obliberated, wiped out, nothing but ashes and cinders, this needs to be confirmed.

Funerals are going to be hard going.

So many countries have offered help, makes one feel so humble, so good knowing there are people out side of Australia who care.




@ Bill
I see someone has posted a photo of the geranimum diode, Bill, this diode is a glass encapusalated device, you can even see the "cats whisker" inside it. These can be found in transister radios, look in the IF section, around the tuner section.
