Hello,
Looking for some advice on this one. Background - I have a car that has a swapped engine and will soon have a Teensy 3.2 installed that is helping with some of my integration work. I would like to add a few features going forward to the car in general:
- Android based radio
- Wifi Hotspot/Data stream of sorts to run that radio
- GPS or any style location tracking (seems to be worth $50-75/year on insurance! At least when using an Agreed Value plan)
I have two ideas on how to do this:
-
Use an Android radio with a sim card with some sort of Android app that does tracking. Use the Teensy to intermittently turn the radio on to update location, etc, when the car is off. Seems like this could be a little power hungry on multiple week stints where the car sits.
-
Use the Teensy with a sim card, and GPS shield and have it do the location portion. However, I would like to use the same sim card to get internet provided to the radio, most likely though wifi hotspot or similar. I'm not sure of a good way to do all this from the Teensy... Or if it's even feasible.
The GPS tracking might be helpful in the event of a stolen car, but I also know the good thieves are not going to easily be tracked by a simple GPS. It's too bad LoJack is out of the business now! It would be cool to make a similar device with an Arduino that could broadcast on the Police bands like LoJack.
EDIT: Came across something that might work... There is a device called the Harmon Spark, I'm sure there are other similar devices. Provides a wifi hotspot, etc for a car. I could use the Teensy to turn that on and a GPS shield on the teensy, covers all options I believe.
