I picked up my magnets at Radio Shack. $2/5. PN 64-1883.
That's after buying a pack of "fridge" magnets that DIDN'T work either!
They seem to work fine, doing a brief test. I used a "thick" drop of RTV to secure them. They seem to "stick" decently, but I think a hard jolt may dislodge them.
I found a spot to mount the sensor on the down tube, basically butted up against the BB.
I still have to lengthen the wire though so I can mount the head where I can see it with my bad eyes. Waiting for a friend to stop by that does electronic assembly, since I don't have a soldering iron.
BTW, I used 3 magnets and set the computer to 5555. Gotta save weight!
