“That is the answer I am looking for. This feedback problem has cost me a small fortune.
- Agree; the same here.
It will stay a toy forever till another system will be involved. And that’s exactly what Richard did, he used oscillation circuit for triggering the back emf system (feedback) which gives enough power (juice) to charge bttry and give some more to load.

good for him .....

lol

i hear he cant stop blowing sh!t up ........ LOL!!!!! ;D

damm   silicon ..... :)

ist...

too bad you dont understand  what i have showen lol

what is the relationship between copper magnetics and steel?

just standard generator action here ...  POWERED BY  A JOULE THIEF   THAT NOW CONSUMES VERRY LITTLE ... ;)

i took a few pictures ...

what!?!?!?!?!    plastics become magnetic at high freq....
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?!?!?!?!

I have a quick question, because I see something bright!

My newest shipment  ;) of various things came yesterday. more 3904's etc. I got a 2N2222 transistor housed in a small metal can. It looks like the one gadgedmail is using.

I know his is germanium. Is mine also when the housing is in the can?

I tried both ways, and the first way, no lights, but the other way around it became REALLY bright. I have some other 2222's and when I tried one of them the light was very dim. It/they were all housed in the little plastic half can.

Does anybody know if the housing says it is germanium?

=====
@Gadgetmail,

I also tried the only PNP transistor I have in the same ckt and there was no light either way.. :( so, I am still curious about your PNP transistor...

More later, but I wanted to get the answer on this germanium question now if I can.

Thank you,

jeanna

You shown nothing yet, but “him” did ;D.

It “consumed a little” only because it needs a little; u can’t beat a school’s physic ;D; “him” did…

@Jeanna
No the metal can is just a different package . I have Lots of silicon Transistors that are "Canned" Look up the number on the transistor to be sure . If you need one (Germanium ) Give me a Pm . Also i used the PNP germanium because it had High gain for this circuit . I haven't tried to replace it yet but i am in the process of Building one more and getting read to solder it up . I should know in a little while if the .20ma is good on silicon too ...

@ist . Wow .. Answer What Is a TPU .  ;D
