GPS to cell phone output somehow ???
I did a few :search: s and didn't find any solution yet, but here is one project I have been thinking about and need help with:
GPS will provide NEMA serial data.
Pre-paid cell phone - provides transmition device (SMS, fax or data upload???)
Need to "hack" into phone to trigger phone to transmit serial data
Has anyone figured out a way to trigger something (like a basic stamp device) via alarm output and/or the cell phone (set to auto answer and with a hands free/serial data kit) to use the same cell phone (give it 2 min to hang itself up) to transmit text it sees on the serial output of the GPS (lat/lon position with some other "junk") out via the cell phone via
1. SMS message to preset addresses
2. Fax to preset phone numbers
3. Upload data to a website via modem protocol
Device would then be hidden really well into vehicle with a wire to charge up cell phone and GPS batteries. If you want to know where the vehicle is, you call the hidden cell phone (set to silent ring) and hang up. It will then output it's current or at least last position to you via one of those mentods. With lat/lon position you can map that via mapquest or something and determine location within a block or so.
