Default Re: A home brew meter re-magnetiser.

Stupid sideways thought....

If you can wind some turns around the Avo's magnet, you could sneak in a regulated low voltage power supply to provide a bit of extra mains powered field. It could even be adjustable for future re-calibration.

A different approach to adding a little PSU and an opamp!

Can't afford the volcanic island yet, but the plans for my monorail and the goons' uniforms are done
