RE:hand jive

Brian and the list,

The Pulse generators look interesting (but expensive)! Would there be
an advantage to having a shaft encoder to spin rather then a pair of jog
buttons? Would the shaft encoder just provide pulses, or would it be
"calibrated" like a real hand wheel? What do the big machines with this
(electronic handwheels) do?

I interfaced a shaft encoder through a spare pair of bits in a parallel
interface to my RDF (Radio Direction Finder) hardware (Stepper spins
antenna, A/D sync'd with antenna direction takes signal strength data).
I didn't have all that smooth a motion, probably due to overhead of
reading the encoder. I want to try it again with something like US
Digital encoder interfaces (like DRO). I guess one could interface the
encoder and simulate keyboard codes? Or if you're writing your own
program... Any thoughts writers?
