Re: Range Finder
Well, these are the difficult questions to answer. I have been debating with them myself.
I would like to have something around 50 meter within 1 meter precison. But I'm on a tight budget so I think that laser is out of the scope.
I have been looking around for some technologies to do this namely:
Laser - Too expensive. Also I think that measuring 50 meter will be difficult to capture the reflexion.
Infrared - Good but only on the 10 meter range. Also, it gets very attenuated on reflexions.
UltraSound - It seems the best option, because of the budget, but not good enough for 50 meter because of ghost reflexions.
With all these limitations I don't know if this is really feasible. Am I right?
