Hello,
I've had 3 year of electronics and always dabbled with circuits and the like, but I generally get confused with circuits that utilize transistors and transformers. These two circuits intrigue me, but I can't seem to figure out how current flows in each circuit (including back emf).
One is called a "joule ringer", the other a "slayer exciter". I successfully created the joule ringer, except I used a C9014 transistor and it can only be on for a few seconds before it gets too hot. I used a 2n3055 as it mentioned, but it wouldn't even light a small bulb (that's probably due to my poor transformer design, it was 15T primary, 203T secondary on a 3/4 steel bolt).
Super Joule Ringer:
Slayer Exciter:
So, here are my questions:
(1) What is the difference in operation between these two circuits?
(2) How does current flow in each circuit (including back-emf)?
(3) Which circuit is more power efficient (assuming both run on a 9V battery)?
(4) People have mentioned that you should "tune" both circuits, how do you do that?
Thanks,
- Ben
