For giggles and grins...

Light travels at about 1 foot per nano second.

Kick a PIC at say 50mhz (skimask says it's "ok")

Tcy is 1/4 clocking speed or 12.5 mips or 80 nano seconds.

One Tcy = 80 feet or 40 feet out and back round trip, so 40 feet would be the step resolution using time counting.

Now, clock that PIC at 4 Gigs and you can be down to 1 foot resolutions (just before that billionth of second when the PIC releases its magic smoke).

At 50mhz, it could be interesting to see just how high that airplane is flying (NOT!), give or take 40 feet. Kids, don't try this at home. We are professionals.

Thanks BrianT,

Your link is great, especially that one:http://www.acroname.com/robotics/parts/R11-6500.html.

As almost always, particular modules and parts exist but finding the correct wording for a good web search is sometimes the most difficult thing to do - Ranging Module was the key.

I already ordered one part - getting ready to play with it
