The problem at hand is a relatively accurate (1/8") measurement of a
cart's position for introductory level physics course. The sampling
rate would be in the area of 5 s/sec. The measurement will go up to
about 4 feet (no more than 5). After doing some googling, it seems
that the best options I have are:
--String Pot
--Laser Measurement
--Ultrasonic?
The string pot seems like the best approach, however, may be out of my
budget. I'm fairly electronically savvy and was wondering if it was
possible to build one of these myself. I figured just getting the
distance translated into a voltage would be sufficient for porting
into the data acquisition setup I have available. I saw Spaceage
Controls Series M Position Transducer looked pretty good, but I'm not
sure over how much one of these might cost.
