Ultrasonic distance measure Answered
Hi eveyone, I'm an assistant cameraman in film and tv and sometimes I've hired in a professional distance measure device to help with really tricky shots. Trouble is, to buy one costs an arm and a leg, I was just wondering if anyone here had come up with an affordable version. The device sits on top of the camera and sends out ultrasonic pulses to where ever it's pointing and displays the distance in feet and inches on a LED display, that constantly updates. That's all it needs to do. Should have a range of 2' to 15' and be +/- 1" accuracy.
Any help would be greatly appreciated.
