I just bought an electronic tape measure(ultrasonic) from Radio shack for $25.
For the price it seemed to be a cheap ranging unit for my robot. I've taken
it apart(partially) and the transmiter/receiver section appears to be made
up of three 555 timers and an op-amp. I have not looked under this board
which I belive will be the logic chip for the display/keyboard.

Has anyone interfaced to this thing?

This would be alot cheaper than the Polarod board.
