I've been approaching this from many angles and contacted dozens of people. I'm going crazy. I'm getting bloodied. I can't believe it's this difficult.
I'm going to back up to the very beginning and just pose it as a simple query. Maybe I'll get lucky.
Is there an ultra sensitive gauss meter circuit/schematic anywhere that constitutes a simple indicator? No measurement. No scaling. No accuracy. Just hall device/ic on a board with power supply inputs, a bit of signal conditioning of maybe a dozen more parts, and a little relay.
Tiny bit of gauss detected, little buzzer or light goes off. That's it. That's all!
Anything?
