Hi guys,
I don't know much about actual circuitry, I can solder, desolder, run some wiring etc. But major building I am no good at.
On to my question(s).
I want to build two parts. I want a main box, can be most any size,has to be easy to wire into say a computer power source, a vehicle power source etc. I want it to send a signal to a much smaller and preferrably thin as possible. secondary part. The signal it sends needs to be nothing more than a Hey you there?
The second part, needs to be small as possible, able to cover with plastic to make it water proof. I need it to have a gps module like a jupiter 32. The module has to be able to recieve GPS signals when indoors and blocked. The jupiter supposedly does that in parking garages, canyons etc.
It also needs to be able to transmit a SMS to ,at a minimum, two phone numbers.
What I am looking for is, the main box sends a signal to the secondary one. Hey you there? Yeah. Secondary stays in idle mode(battery power is a major issue. Want to use a little as possible on the draw until they are seperated. ) Once the secondary doesn't pickup a signal within a given time frame say every 15minutes. It powers on and starts sending its GPS coordinates and an ID# to two phones via SMS.
That is the basic idea, again my knowledge is limited. If it is something you think I should take to a prototype builder, that is fine too, but I'd need to find a good legit one around chicago.
Any help and or part lists would be greatly appreciated. I'll pickup some books when I get a chance.
Budget I'd like to keep within $100-150 range.
project time asap obviously But in reality 6 months- year a complete product ready to send out for a small production run into a mass production run 2-3years down the road.
