Joule Thief

[jonnydavro]

Hi, :)I had a play with my jt pulse motor today and put another rotor on the unused end off the coil and now i have got 2 rotors spinning.I used 3v for this test and it was like a chinook helicopter.Here is a video off it.

The rotor off my jt pulse motor sits on a dc motor for a bearing.When the rotor is being spun by the coil,the dc motor is acting like a generator so i wondered if i could use this output to run another,completly seperate joule thief and the answer is yes.I only used one rotor for this.Here is a picture.
@pirate.Thanks Bill.I am following what you are doing closely and enjoy your vids.Keep them coming

nice video jonny...

got an idea for you 

take a bunch of those units stand them vertical form a ring of many of them   throw the ring of em inside 2 pancake coils ...

1 top 1 bottom

harness the extra flying feilds ..  but if you fed power into the pancakes would you not have and electron pump 

neat in the vid how your orange stripes at diffrent points sync with one another... and at other times do not ..  hummmm  unless it is my eyes but are they not pulsed at both the same time..................

@IST.Thanks.i might try your idea out on a smaller scale sometime in the future credits to you.Regarding The rotors syncronisation.They are in sync it's just that they are rotating in opposite directions,its not your eye's.

@All

Just a thought/question that probably has been answered in one form or another:
I'm winding a pickup coil over/between the windings of my current big toroid(1.125") using 22 or 24 gauge enamel magnet wire. Now, once I run that through a bridge and produce DC, is there any way to put that back into the JT circuit? I'm thinking past the battery(I'm using non-rechargeable and don't want it to blow up). Would it provide any boost whatsoever? I'm thinking(dangerous, I know) that maybe a good point for the + of the bridge would be on the + leg of the LED, between the diode and cap. Correct me, please, but  I'm thinking that the diode would keep it moving forward and just add it to the current going into and beside the cap. Then hook the - from the bridge to the spot on the - side of the LED between the light and the - side of the cap. That way the LED would be the diode keeping things in one direction and the cap would smooth out what goes through the rest of the circuit so I don't fry anything(just my luck).

try this (seen it in a video and its really cool) if you have a magnet that will fit inside a torrid put it in! free style, you will want it enclosed in a tube or something tho! if you dont, build an air coil transformer and try that too! there is a video on you tube of a guy using a bedini motor and had a air coil. he had a small neodinium magnet he put in a tube and placed inside the transformer it sounded horrible but the lights got brighter!
