I need help on my joule thief circuit that won't function. Answered
I've been attempting to construct a Joule thief circuit but it appears the circuit won't function, even with the essential parts that I scavenged from a CFL bulb. The parts are: 112dl transistor, LED, ferrite core, 1K ohm resistor, 1.2volt rechargeable AA battery and magnet wires, 14 turns on the core and I attempts to switch the connections on the wires, it appears no hope. I've watched all the tutorial videos on YouTube but appears to be failure. If you found a solution to resolve this issue, please explain it specifically. Thanks !
