Ringing a magneto phone bell with a motor driver, but volume too low

[didg]

Ah, a fellow escape artist!

@SteveMann

The two windings on the ringer were connected in series and in phase. Just experiment with various combinations until you find the best arrangement.

What does "in series and in phase" mean in this setup? (Im still learning)

Thanks for sharing your circuit! Ive seen quite a few transformer circuits, so this might just be the way to go. Got some orders to make.

I’ll update when I’ve got some progress to share.

Thanks all!
