Hi, all:-
So we have this 3-axis magnetometer kicking around - probe plus a benchtop instrument with multiple displays. It's good for measuring the earth's field. This one has the option to have the bandwidth really low, presumably to reject 60Hz hum, and they also made a high bandwidth version.
I asked the company what parts I would have to change to make it high bandwidth but they're ignoring me. So I took the cover off and it's a real horrorshow inside- fly wires, fixes, hot glue all over the place.
So should I do a tear-down page or video exposing their shoddy workmanship for all to see while reverse-engineering their design (their website looks like they have pretensions of being a legitimate company) or should I just forget about it?
Looks like it might take an hour or three to figure out what they are doing- it's got some OPAxxx op-amps and a bunch of other stuff (looks needlessly complex, actually).
I need to end up with a 3-axis magnetometer with analog outputs for a couple gauss. Preferably without spending too much scratch.
