        Ugh...There comes an old, long and sad history...

        Ok. Many of you know I live in Brazil. "News" like these are always=
 celebrated here. Not only for the ones who need this kind of accessory,=
 but for the ones who copy it and sell for a rip. And this is how this=
 history goes...

        I made it. It was just simple! A modified cellular phone, one TCM3105=
 (yep, that nice modem used in BAYCOMM), a GPS module and a 8751 processor=
 to control everything. The entire circuit was simpler than stole a candy=
 from a child. The 8751 took the NMEA output of the GPS (which is nothing=
 more than current-level RS232), processed it to get latitude, longitude=
 and speed, encoded it with the TCM3105 and sent thru the cell phone. In an=
 event of the car being stolen, or the owner sequestred (is it the right=
 english word? Or would it be "abducted"? Ah, I think "Rape" is the right=
 verb...Oh, 08:30am in a sunday, lemme sleep!), the car would open up the=
 cellular connection, and start transmiting the position, along with audio=
 - if desired - of inside the car and the "porta malas" (brazilian friends,=
 help me with this word, I think is "truck"). Of course, the reverse would=
 also be possible - you could dial in the system in the car, and get it's=
 position at any time. Since there was a password for that - which only the=
 owner would know - there was no danger of his wife "spying" what the hell=
 he was doing at 02:00a out of his home :o)

        No need to tell - Project ready to sell, the plans were robbed.

        I was planing an entire company - would provide the sales, installation,=
 maintenance, survellance, and help the policy in case of stealing. Almost=
 everything was done. But the project was robbed, and cannot protect itself=
 ;o) In less than a month, it was produced and sold here, and everywhere.

        Of course, I cannot prove this is MY project. Maybe just my idea. Maybe=
 just a coincidence.

        But here was my history. The project who almost was sucess ;o)

        Life is harsh sometimes...
