<DIV>Dean / Ray </DIV>
<DIV> </DIV>
<DIV>Dean,Good point on Ray's project.</DIV>
<DIV>I guess the question is to find out what you are trying to do, Ray.</DIV>
<DIV> </DIV>
<DIV>That is, if you are attempting to measure time of flight of light you may
be talking an advanced project where specialized
hardware/ knowledge might be needed. </DIV>
<DIV> </DIV>
<DIV>Reference designs are a good place to start.</DIV>
<DIV> </DIV>
<DIV>Yeah, breadboarding in this range would be out.</DIV>
<DIV> </DIV>
<DIV>Might suggest playing with sonar first. You will learn a good deal and
sound's propagation rate is 1 millionth the speed of light. Master that first.
