gdsports:
Google for "laser range finder arduino" or "laser tape measure arduino". People have been hacking consumer grade laser range finders/distance meters for years with some success. If you want one intended for DIY/hobby use, search for "lidar light" but this only good out to 40m.
Tried doing that, couldn't find much really
And yeah the lidar light was the best but its only for 40m, I need it for at least 80m range
CrossRoads:
Lidar-lite 3 on sale now for $119 for those interested in lasar distance measuring, to 40m as mentioned
