Joule Thief

[innovation_station]

ill just laugh at your stupidy !

ist

lol

does anyone think a motor can be used as a transistor .. as a replacement

perhaps one could harvest from the motor coils to ADD to the jt input ..  just a 1.5 volt motor

Hi all,

Just thought I might throw my ore in here and pass you all an idea I just had, and maybe it will settle the forum down a bit.

Has anyone ever made a Joule Thief using a copper wire and a Iron (uninsulated) wire as the bifilar windings?

Has anyone used just iron wire as the secondary windings? (use insulated garden tie wire)

I was thinking the extra iron of the iron wire should add to the magnetic fields produced in the toroid's, thereby making a higher magnetic field when energised, upon collapsing, it should give out a higher energy!

If you wind "over" the top of a previous bifilar winding, then you will need to insulate the layer beneath it with tape to prevent short circuits.

2599 = just one of my coils of tiny iron insulated wire.

i once done a secondary winding with steel wire that was insulated over a ferrite toroid it cut the noise of the toroid down a bit but it give a lower volt output.. and lowered the feq alot.. but didn't change the input draw..

@ Kooler,

Now thats interresting, it is for me anyway, cuttting the rf noise down is something thats needs doiing, and you noticed the current draw wasn't affected with your JT. Actually your reply has given me one of the answers I have been looking for in the Stubblefield forum, and that is frequency.
Iron is more resistant to electrons than copper, and it seems to retain its magnetism for a short time after power is removed, depending on the type of iron used, it now seems to me it is used for the frequency control also, might be a valuable key.

Thanks Robbie.

Please stop insulting other people and only
post in your own threads.

Otherwise I will set you on read only again.

Many thanks for your understanding.
