Hello Bill

It looks like he is collecting the negative BEMF allso.
It can be done with the JT allso.

Just turning a diode around on the 2222 transistor with the circuit I'm using.

You can hook your meter or leds or what ever to the backwards diode.
then you can connect it to the negative side or positive side of your source battery.

That way you can collect the positive BEMF and also the negative BEMF.
Hello Slater . I know what you are talking about but could you post your schemitic with the double BEMF for others to Follow . The Search on the site is Not very User Friendly when it comes to searching for post with attachments..Thanks . Greta job on that 480 primary . i bet you double that and you can loose the darlington .

jt 600 turn secondary wound with mk2 feedback wind 22 ga

done

ist!
To understand the action of the local condenser E in fig.2 let a single discharge be first considered. the discharge has 2 paths offered~~ one to the condenser E the other through the part L of the working circuit C. The part L  however  by virtue of its self induction  offers a strong opposition to such a sudden discharge  wile the condenser on the other hand offers no such opposition ......TESLA..

THE !STORE IS UP AND RUNNING ...  WE ARE TAKEING ORDERS ..  NOW ..   ISTEAM.CA   AND WE CAN AND WILL BUILD CUSTOM COILS ...  OF   LARGER  OUTPUT ...

CAN YOU SAY GOOD BYE TO YESTERDAY?!?!?!?!

@ all:

Above is a link to a video I made on the JT Coil Light.  I tried an experiment while making this video.  Since I have a good supply of the 3904 transistors, I decided to up the input power to see if it can take it.  I used 3 AAA bats to drive the jt toroid circuit and the output light is very very good.  Better than it shows up on the camera even though it looks pretty good there too.  So, it did not hurt the transistor or anything at all.

I know I can use an MK1 style toroid to achieve even better results using an AA battery, but I just want to see if the transistor would handle a bit more input power....and it seemed to.

@ IST:

Very nicely wound man.!!!

nice video bill  :)

thanks for the complement  :)

im just whipping up a solar supply  useing a ramma solar light unit   but i bought some aa solder on batteries a while ago just dugg em up 

i will use 1 of those and 2 solar chargers ...  for a supply jt to power this 600 turn unit ...  ;D   the battery im useing  SAYS AVALANCHE!!!! LOL  NI-MH AA1600MAH 1.2V

SHOULD MAKE A GOOD SUPPLY

ist

this one shouldnt take long ...  8)

@ slayer007

Congratulations. I think you are the first to light a CFL from a 1.5 volt AA battery using a transformer you made yourself.  I made a schematic that I hope is correct.
