Joule Thief 101

[Magluvin]

One can imagine a reedited Dr. Strangelove where a few times in the film they cut to some freezing sailor standing on watch on a navy ship way above the arctic circle.  The freezing sailor doles out some quixotic "pearls of wisdom" that add to the whole unreality of the scene.  Blame that behaviour on the effects of the chemtrails.

Thank you for your cameo.

Lately there has been a steady increase in 'mercury' being found in west US. Not just in rivers and lakes but on the land. Mercury is pretty heavy. There is not that much westerly wind to say its from power plants, even if it were, the concentrations found it could not possibly be. I study this stuff. You dont.

Besides, even though you dont believe and have always 'denied' chem trails to exist, the gov has already admitted it but claim other reasons for it, like trying to reflect the heat of the sun to try and cool the earth down.  And that clumsy admission is fact that they do spray, not assumption. Even Hawaii has had court battles to keep the chem trails from being dropped over their land.  I can pull the documentation of that if you like. But you will just say its bogus spaghetti what ever. But at least the readers can investigate themselves and see what garbage you post.

Tired of it all, for some time now.

I don't post garbage but speaking of garbage, how is the "resonant Joule Thief" cumming along?  Anything exciting to post?

I have a new one going together this evening. Just spoke to Brad about it. Im using a 6mm OD ferrite toroid(input choke off a small cfl circuit board) and starting with 2t by 2t and will step up the turns if necessary incase of operational issues. The reason for beginning with 2 turns is to try and get the operating freq up to where we would need to be to get the core freq to resonate. The 3904 will operate up to 300mhz. Smoky said in a recent post about getting the core into saturation. So smaller core, easier saturation. Especially with the small amounts of power we are dealing with.

Windings will be 30awg. Very short wires so low resistance. Putting on a square of RS circuit board.

Great so post it on your thread when you are ready and we will see if a pulse switching circuit takes wings and really flies when you convert it into a resonant circuit.

When it becomes a resonant jt it will get its own thread.
