Personal (IR) Radar

[chris] sent in this inexpensive personal radar project. It uses a servo mounted IR range finder to locate and display the distance to an object. (Lake a parked car as shown in the demo video) The project is destined for some robotics projects – and who doesn’t love LED display proximity sensors. It makes me think of the direction finders in every other 80’s action movie. It’s gotten some attention on Digg, but I like it for the inexpensive build and the excellent use of a PIC 18F452.
