Joule Thief

have you hooked up another 4 watter in place of the soup can?

That's a cool idea.

-----
I found a switch that cuts off the power completely.

(You might remember if I use the unmodified LoA light in a jtc/secondary, the lamp switch is not able to cut the power completely when I wish to turn it off. I have hypothesized that the caps etc in the protective circuit are sending waves back through the toroid just enough that the battery keeps being used to turn the transistor on until the battery is 200mv below the turn-on voltage of the transistor.)

The solution is a standard AC wall switch.
I also bought a plastic wall switch box which will hold both the switch and the battery.
Perhaps/probably I can get the whole jtc plus battery into this box and use the switch.
Switch- $1.00, plastic switch box = $0.39 all in all a cheap and easy solution.
I will make it look OK and possibly post a pic later.

i have been diode hunting ...  lol

and i yep im guessing i found better ones ... 

in my 3 turn jt that charges a tonne of things ... 

i used a CRYSTAL DIODE BOARD .....   lowest resistance is 6.xx kohm   ...  i just found 1.2kohm.... 

any ways it is the one that pumps the hardest...  so if i lower my diode resistance will it give me higher rectified volts...  lol

?

ist!

i found many high mega ohm  doides as well   

this plays the largest roll  ........ 

as i have seen ...   
   
guess i pull some out and see what the results are ......  : )

Xee2

If you reversed the connections on the second trigger would you then have -HV or are they polarity sensitive. If you could reverse it, you might double your high voltage.

that is funny you say that and ill tell ya why ...  some diodes give me same resistance both ways ... otheres block it .....  and i have pairs of them ....  still same 1.2kohm but do not pass other way ....  lol 

probally work well for my use .... 

what ya think?

W

in tests i did and shared public ...  i found the 6.xxkohm ...  to charge higher in volts from my supercaps .. to the second super cap ....  long b4 the supercaps was full ..... 

makes ya wonder ....  lol  ; )

hence why i used it to recharge the gel... 12vdc ...  and it charged verry well ... : )

so now i cut it in 4  the resistance....  what will be the result?   

im still hunting ... as i dugg those out there restiance is diffrent then mesured in board ...  lol

i have qutie an assortment of diodes ... 

and i know i need a better one ...

As far as I know, when you check a diode you should get a high resistance in one direction and low resistance in the other direction. This is using the resistance reading on the meter. Now that they have a diode setting on most meters, I'm not really sure of the meter circuitry that gives you the reading. I would think that the diodes that give you the same reading both ways are questionable.
