For my freshman design class, I am redesigning the goniometer. The goniometer is used by physical therapists to measure the angle in which a particular joint can move. For my design, I want to use lasers to help align the device with landmarks on the arms/legs to get a more accurate reading.
I don't know much about lasers and was hoping to get some help. Ideally, the laser I would get would be the thickness of a coin. It obviously does not need to be super strong or anything, just small and inexpensive.
