Joule Thief

[poynt99]

This is a rebuild of the JT topic after Stefan messed up and merged this original thread and one that was started afterward because I did not allow the whining and BS for which Wilby is famous and evidently has a real knack for.

(In case anyone missed this in my edit of the first post)

So, poynt99,
where are the tips how to measure the Joule Thief ?

MH,

I agree with most of what you're saying.

Back to the cap. Yes, the now infamous Mr. Gadget doesn't quite understand the implications of what he is doing by discharging that huge cap into that poor AA battery. Not only is he stressing Mr. AA to pieces, but he's wasting a great deal of energy by doing so. But alas, it will only end speculation that much sooner, and as I said before, I give the GJT device less than 10 hours of operation at 1W. But then again, the entry for the OU prize won't be official until Stefan receives one to test. Will it make it to that stage? I am doubtful.

Maybe it's possible to discharge the Ultracap through a suitable transformer and dump the charge into a lead acid battery at the correct voltage...And then power the load from the battery.
Lead acid battery's are quite good at regulating and if the transformer steps up the voltage, current will automatically drop.

This way there are no small battery's to fry, and it'sa good way to see how long things last...

Marco.
