i'am fairly new here.
I have a little bit experience with the arduino now.
But now my Question. I have an old Google G1 (handy) laying around.
It is fully functionable. Is it possible to use some of the parts of the G1 for the Arduino.
Maybe Display, WIFI module, Bluetooth module?
The simplest way to reuse is probably to buy some bluetooth for Arduino and let them send data to each other.
There are Android Bluetooth terminal apps that can be used to control the Arduino.
Don't know the G1 but I imagine that it will be quite a challenge to harvest the chips in the first place, and reuse them from the Arduino without having datasheets (assumption)
But the proof is in the pudding test, so hack the device and give it a try
