Joule Thief

@Jeanna

I just realized something...I remembered you were having trouble getting the 3055 to turn on!  Was this a TIP3055 or a 2N3055?

I have 2 kinds
2N3055 - gift
2N3055HV - allelectronics

Why do you ask?

Remember I AM using a secondary/pickup.
I have only used a secondary for turning on lights since I discovered it was possible, I think , on Jan 5th, maybe before.

The basic joule thief uses more juice from the battery to power everything. The secondary does something other than that. It is not free, but it is not straight juice either. The bjt is not straight juice as it uses back emf and C-E amplification, but the secondary is all bemf and no C-E amplification. It relies heavily on the switching speed of the transistor.

Most of my experiments have been to investigate what happens to the circuit and its energy requirements when using the secondary alone to make the lights go on. Later I am hoping more than lights, but that will only come with much understanding of all the above.

@ Jeanna:

The ones I sent you were 2N3055's.  Just in case you were referring to them.

I just realised that there were multiple 3055's out there and maybe you are using something different then what other people are using.  I wanted to help because I have had my best successes with 2N3055's!
