Stop-Light Alert with Arduino

OK, you may have noticed I have a bit of interest in the arduino platform.  So what the heck can you do with this.  Well the link below has an interesting write-up of one gent whom uses one with a GPS setup to alert him when he comes upon a red-light camera.  Not a bad idea since these cameras seem to be springing up everywhere these days.  Even in Rochester, New York they are gaining popularity (and a new source or revenue).  Want to make your own, check it out at the link below:
