Mark,

nope. Mag's are on the waiting list here for quite some
time. I'm more into radiation detection now.

But when I finally have the time and motivation, I'll
try your circuit that I also included on magnetometer.org

I'd love to build a (working) proton precession mag -
I actually started one a while ago - but that one never
worked since I don't have a powerful enough power supply
to drive the coil. And then the readout circuit is very
critical - high gain, loves to oscillate!
But one day...
See there comes my passion for particles into the game again.
Spinning protons and magnetic fields... WHOOOAAA :-)

Yours,
Hannes.
