While waiting for parts to come in for my ZE swap, I did some serious work on my carputer setup. Here's what I've got so far:
2ghz VIA C7 w/1GB ram, 120GB disk running Debian Linux (sid)
USB GPS with accelerometer (for HP estimates, skidpad, etc)
USB OBD-II link
7" double-din SVGA touchscreen
Mini USB keyboard and Logitech SpaceNavigator (volume/track selection)
7 channel homebuilt Tripath amplifier (6x100 watts @ 0.1%THD, 1x200 watt @ 0.1%THD)
12->24VDC SMPS power converter/regulator for amplifiers
8 channel USB soundcard (Gigaport AG)
USB ground loop isolator with external battery pack/relay activated charger
Infinity Kappa 60.7CS components (front)
Infinity Kappa 63.7i (rear)
Generic 2x10" sealed subwoofer (soon to be JL audio)
All audio channels are independently driven using a Linux ALSA software crossover (ladspa butterworth filters). The crossover points and Q value are controllable on-screen in realtime. Also has a 16-band graphic EQ.
I developed the interface software myself in perl (yeah, yeah). Here are some screen shots:
Main interface, with options menu open:
Track/Album selection window (buttons at top act like Sony T9 input):
Crossover configuration. Those graphs are all accurate btw.
For GPS, I suspend and resume a vmware session running iNavigator. It shares the sound card with my media player perfectly, so gives audio directions as well.
As my system is linked to the engine computer with an OBD-II USB interface, I've also got ScanTool installed to monitor engine conditions and read trouble codes. I'm currently working on a perl module to read the information directly and present it on the main interface, as well as using vehicle speed to dynamically adjust volume.
It detects my phone via bluetooth and logs on the 'net when I get in the car. No call answering yet (I use BT handsfree for that).
The SpaceNavigator is a USB HID device that I mounted on the dash. I removed the right center vent (plugging it with a rubber stopper) and made a custom mount for the spacenavigator (metal base removed). It looks very cool and stock.
It performs tons of actions, such as volume control, track forward/back, fast forward/reverse, mute, playlist manipulation, etc. In fact, I use the touchscreen very rarely now.
Unfortunately I don't have a pic of it installed, but here's the device I'm talking about:
All and all, it's coming along nicely.
