DIY Magneto Ignition Timing Buzzer

My magneto timing buzzer build, with LED indicator and output jack for headphones.
Includes a wiring diagram so you can build your own!
This is a standard buzzer circuit adapted for headphones rather than loudspeaker.

cool project, looks like the camera picked up the LED pulsing from the 555,

Fantastic. New subscriber here and I am going to build one of these as soon as I get a chance.

My morris mag won’t work with a conductivity tester because it senses conductivity the entire time. Will this work on induction?
