Thread-topic: | COIL WINDING THOUGHT |
> If I see smoke and hear a bang I will know that you mean business. You could also put a small steel plate in line with the coil to monitor current - the mag field will pluck it like a speaker. Tune for maximum sound rather than maximum smoke! (It would be worth putting a small permanent magnet on it, or it will be pulled by both half cycles and will sound at just under 18kHz, higher than most adults can hear.) 73, Chris G4OKW |
