Thermal Sensor and Load Sensor

[Dave Williams]

-> but you can make one from 2 magnetic sensors at opposite ends of the
-> shaft the phase difference between the 2 sendors will change with the
-> amount od load on the shaft

 That'd be some bitchen sensors; you'd need accuracy down to some
fraction of a degree.  Then there's the problem of mounting the pickups,
considering both ends of the shaft move vertically, the if it's a live
axle, there's a horizontal component on the rear joint too.

 Once you get all that you can start writing some fancy filtering code
to smooth out the torque variations from the U-joints, the gears in the
trans and rear end, and the pulses from the cylinders, plus harmonics
thereof.
