Joule Thief

Hi E2 good to see you . I saw in my small town post office while i was there the fex ex man was dumping many many large bags full of packages to the post office to help them out So Fedex is using USPS right now because they are swamped ..  .

  Ok, thanks for the info.
  I removed the 10 led bulb, and added resistance to a single led to avoid it blowing. I'm looking into the diode(s). I feel that any resistance on the led is just waisting energy, though. The diode on the primary will not light the tuning led without the cap, most any cap works with the diode to brightly light the led, but I'm trying to tune the circuit now.

NickZ . yes that is what i also see . the second diode will not lite a load without a cap . BUT once it is lit that cap will need to be adjusted by paralleling caps . i saw a point with the cap box . that even the cap that makes it dim is not necessarily the right balance . i can see sometimes on the others that i am messing with sometime the wrong cap there can make it discharge faster than without any diode there at all . I had to gang three 76pf together the first one . two wouldn't work 4 wouldn't work but  three would  make it charge .. .So i am using that method to replace the cap box when i find to correct balance.

  Ok, got that.  My battery and cap now are showing 0 volts.  You're right about the wrong cap value can discharge the battery and input cap. Now I know why. I'm using the .0001 (102) capacitor, and 1n4148 diodes.
  So, now I've got 0 volts input, BUT, the led indicator light is still on, ferrite rod is still ringing. 
  Plengo is right,

Plengo knows his stuff . so does Fausto . You all see a little of what i am seeing . I am not using an led as a diode but i did put one across a diode and it does light however it eats the charging so i removed it on the second one i made. Also the circuit will oscillate all but it self and i believe this is purely from the diodes and wire ,maybe picking up one of the millions of radio and microwaves and making Volts or ............

Even if the led is only slightly lit on the LOAD  when ran but 1.2 volts you know it is oscillating .

Been working on another circuit using a fuji transformer and i cannot get this one to charge . It works good but can't get a balance as everything is one wire light . So Bad fuji for crossover no good..
