2001 Acura CL-S T-Mobile Springboard and a good use for a 3d printer
So, my third car pc setup. If you count an Android tablet as a car pc. So in my previous build I used a Samsung Galaxy Tab as my head unit. This went pretty well except there was one irritating problem I just couldn't seem to fix; connecting the hdmi out would kill the gps signal. So I decided to upgrade to a T-Mobile Springboard. And to make a new bezel I decided to try to figure out this 3d printing stuff. It came out pretty good. I the closest I've come to that factory look I've made so far.
In my old setup I used a McIntosh 6 channel amp. It sounded great but it wasn't very good at powering a subwoofer. Since I didn't want to have a second amp taking up space I thought I'd try one of these fancy new class d amps. I regret selling the McIntosh but I have to say I'm impressed with the JL audio. It has no trouble powering the sub plus it sounds just about a good as the McIntosh.
Originally to power on and off the screen and to start and stop music I'd use Tasker to read the charge state and switch off of that. This approach has a number of problems though. Sometimes I'd leave the car in the garage long enough for the tablet's battery to run out. Also Tasker doesn't have a way to actually pause and play music, it has toggle pause. So the play state would occasionally switch for whatever reason. So one other change I made was using an Arduino BT to read the ignition state of the car. The tablet is linked to it through bluetooth. An app called Amarino reads what I'm spitting out of the Arduino and an app that I wrote called Dreambar reads that and turns the screen on and off. It also uses Poweramp's API to pause or play the music. One day I'll get around to interfacing the steering wheel buttons and whatever else I feel like through the Arduino.
