I just got the acceptance letter for RD a couple days ago (proof
, I'm also sure a member of the developer committee could confirm this), but it's not set on my profile yet.
What I'd like to try with the box is getting an interface set up on it to use it as a car stereo with a touchscreen mounted in the dashboard. I've set up a similar system with an old netbook I have, but power requirements for the netbook raise some issues, mainly with draining my car battery. A lightweight ARM system could largely mitigate, if not completely solve this issue.
There are also space issues. I would like something that I can mount to the back of an LCD and have in a contained easy-to-remove unit, instead of having to run power and VGA cords through my dash.
I also would like to use it as a system for managing my door locks, with a USB keypad possibly stuck in the back of my truck bed, where I can enter a pin and have it lock/unlock my doors. I would also like to try to use a fingerprint scanner to unlock the doors.
Here's some pictures of what I have now:
Don't worry, I've cleaned the wiring since then
XBMC with a modified Xeebo skin. This is the best media player I've found for the job. I was using Winamp at first, but XBMC has cool visualizations and whatnot.
Closer up, I've since filled in that top metal bar with a sharpie
Cleaner wiring, though still a bit messy. Note that my truck is old enough that I don't have a passenger airbag.
Not shown: I've got an acutator in the driver-side door, and a circuit that I built to accept TTL-level voltages and trigger it (essentially two relays making an H bridge
, powered by two transistors that get set high by the TTL input. Both relays are ground open and charged closed, so I can set either one high and control the actuator)
Edit: Just to note, I had previously designed this to work with a RPi, but I found it a bit lackluster and not fast enough for what I wanted. Not to mention it inexplicably died one day.
