However, there seems to be a few problems. 1. The Icom PCR1000 receiver display shown was set to 433.125Mhz, which is the same frequencies used by a zillion weather stations, key fobs, remote controls, and other unlicensed wireless devices. Ignoring the interference, just hearing the beacon more than about 20ft away will be a challenge. Driving all over the town looking for the beacon xmitter is futile. 2. The Google Earth display zoomed in to the Street View and showed the specific automobile where the mouse was hidden. Google Earth is not real time and will only show a car that was parked there when the Google camera van drove past, perhaps months previously. 3. The SIFT-III GPS receiver mentioned is probably a SiRF Atlas-III receiver. <http://www.sirf.com/products/multifunction2.html> These are quite sensitive, but doesn't work inside the vehicle trunk unless the body is fiberglass. 4. Assuming luck is with you, and you perform an amazing feat of tracking the perpetrator to a parked car, what are you going to do next? Break into the car to retreive your stolen laptop? -- Jeff Liebermann jeffl(a)cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558

Aw man, you're no fun at all. Besides, you've already got the check from the insurance company, you just torch the car.

One of my favorite sports is to watch disaster movies and find all the violations of basic fizzix for which such movies are famous. I started this long ago, after watching the original Poseidon Adventure movie with a large mob of students from the Naval Postgraduate Skool. The class assignment in marine engineering was to to watch the movie and find all the screwups and impossibilies. They were rolling in the aisles, while I slowly began to catch on. Since then, I've expanded my bad habits. I consider it great sport to deflate movies, great new ideas, patents, product announcements, government programs, and usenet postings. During the late 1990's, I was making good money doing the same to science fiction business plans. I've also played both sides of the fence and perpetrated a few hoaxes of my own fabrication. >Besides, you've already got >the check from the insurance company, you just torch the >car. Presumably, it's the correct car. Wanna try direction finding on a 433Mhz transmitter that belches short bursts of NEMA 183 every few minutes? It can be done with proper DF hardware but it's not easy. I probably wouldn't torch the car. However taking the air out of the tires might suffice. Eventually, I want my laptop back because like laptops everywhere, it's not backed up. Ummm... what insurance company pays in less time than the battery inside the GPS Mouse will last? >Jeff Jeff, the first. -- Jeff Liebermann jeffl(a)cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
