I need lots of help.
I need your help to provide recommended parts, prices and books.
I am the leader of a kayak troop (a group of 30 people), the group is
usually spread out over 20 km distances eg around the bay Mornington to
I would like each craft to send an sms containing GPS data to my phone
or PC so I cam record the details & know their locations (and be able to
sms the sending phone and get the details sms'd back).
What I was thinking was...
Using a pic eg 16F84(What else is there?), an Motorola M12+ Oncore gps
board (What else is there?) and Antenna, an old nokia phone eg
I need to keep the device as small as possible but within limitations eg
below A$100 a piece including phone as each member will have to help pay
I am quite happy to learn to use a pic programmer and program in basic
or c (ex Swinburne bappsc(comp.sci.)).
Happy to write the code, solder the parts, test them myself.
What I would like is someone to tell me what parts I would need.
eg an pic16f84 programmer and 16f84 chips
some plastic board or pcb, an oscillator chip? a serial comms. chip?
Is there a pic chip with serial comms and oscillator built in,
and all I need to do is plug in the chip (use a resistor drop voltage to
3 volt max) solder some wire to the motorola board and modify the nokia
cable and solder it to the pcb.
Some sort of 12 v power supply for the pic chip? the motorola chip uses
2.85v to 3.15 volt power and outputs on the serial ports ttl of 0-3volts
I have no idea where to start.
