I'm really excited about this and just cannot wait for the device to arrive. I plan to install this into my car as well as my motorcycle as a monitoring gadget.
I do have a mobile mount in the car and will get a (waterproof) one for the cycle as well and will be using my android phone as a vnc client to control the r-pi. I am not entirely certain of this yet, a terminal might actually work, too and would be much leaner on the PIs limited hardware.
I am also thinking of disassembling a very cheap mouse to strip it down to the PCB and use the left/right buttons as switches. The advantage of this over custom switches is that there's no extra driver nessecary to connect it to the pi, jut hook it up to the USB port and things should work and make for very easy to use user-interface. Should also help avoid police tickets because here it is illegal to handle a mobile in any way while on the road (except for voice commands, which i really dislike and which wouldn't work in a noisy environment anyway).
As for the PI itself, it would be connected to a flow meter, put into the fuel line (for the motorcycle) or to a fuel injector, which kinda raises a few questions.
1) Is there an ADC or will i need to use an external controller (AVR Atmega32, 8 bit Microcontroller, got some experience here)
2) Can any of the GPIOs trigger an interrupt and will there be a kernel interface for this?
3) I believe the current sitation is that the r-pi should be available from Nov/Dec, is this still up to date?
4) Will the R-PI support suspend/resume (for power-saving as it would be connteced to the vehicles battery), going to sleep while ignition is off and resume quickly when it is turned on. Otherwise, leaving it running and entering some kind of sleep mode would be nice if it were possible.
I have until now only played with a few AVR Atmel 8 Bit microcontrollers, but i have 2 recent degrees in computer science and just thinking of the possibilities this device opens up is mouth watering... The R-PI could be hooked up to the radio in the car as an external source and would enable me to have access to a much larger music library than otherwise possible. The device would also be able to access the internet through the USB tethering, i might even be able to track the GPS location using the phone (custom app which makes it available over a tcp connection).
Just writing about it makes me come up with so many additional ideas, can't wait to start tinkering
Love the community here, btw, and i second the call for a library of cheap and compatible add-ons, such as gps/wifi/bluetooth/screens and touch-panels. Tutorials and how-to's will be very important once devices become available.
Any chance to have java on the PI? In more recent times, this has been the language of choice in many computer science courses and having it would enable more people to work with the device.
Anyway, I'll have to start making some plans as for what features I'm aiming for
I'm looking forward to any news on the project and am following your progress very closely!
