Joule Thief

[Pirate88179]

  Hello Thanks everybody for help, has anyone come accross this.........

     I have a joulethief  with just a small toroid with secondary, and I have an enhanced bridge  on the
     output of the secondary, my DMM reading on this JT was  109.1 volts.

     Then something I tried (which I was told to try) was putting a CAP in parallel with the Base Resistor and
     then I retuned my 1K pot and I now got  110.4 volts.

     Then I tried something more interesting by adding a 5 foot wire antenna to the Collecter of my
     Transistor, and lo and behold I now get  114.1 volts.

     I have not tried a long antenna as yet, but what does everyone think about more volts with an antenna
      ??

Very interesting discovery.  I wonder where the extra juice is coming from?  Radio/tv stations? Atmospheric energy?  Both?  This opens up some new experiments to try for all of us.

Excellent job!

Interesting, and strange!  this gives me lots of ideas

Interesting experment
I don't remember anyone  trying that before.
How is the wire arranged in relation to the JT?

can you try  wrapping the wire  around  maybe 3 fingers to form a loose coil? then place the JT in the center of this coil......I am guessing it  will act like a secondary and pick up  a little more voltage.

i played with this type setup 6-7 months ago..
putting a wire on the collector side is basic radio transmitting..
so it transmits from the collector to the secondary..
cause the secondary is at the same freq as the ant.
so it just pulls a little cemf from the ant. to the secondary..
below i post a pic of a setup i used..   at a certain freq it will double the volts on the secondary but will pull more from the battery also..
i may have the wires crossed on the setup but you need to run your ant. on the pos. of the output of your secondary..

later..

Talking about radioes.
I finished my variable capacitor, only need to add the connection posts somehow (one of the parts moves).
