Quite possible to do with existing off the shelf ultrasonic or diode
laser telemetry being used for DYI robotic range finding. In fact you
can get ones that use i2c for data acquisition.I could probably mock
something up with an arduino unit to do the measurement. Though I'd
need some help getting a projector to use the calculation and hand it
back over the wire to the computer.
