Catches with the laser? You'd probably need to lift an SBC
(gumstix/beagleboard), although you might get away with a CMUCam. Not
sure of the range, especially in bright sunlight over non-reflective
surfaces, like grass. The ham radio one looks more promising, but
difficult and heavy. Incidentally, I looked at the laser range-finder
idea quite a while ago after I saw a documentary on the Dam Busters!
