My low tech, low budget headless car PC
I've been lurking here for a few years and had orginally wanted to build a car PC for my hot rod. The longer I planned the more the technology changed and I came to the conclusion that a smart phone would do 90% of what I wanted anyway so I picked up a Droid X. It's been a good phone and came in handy quite a few times but have never followed though with the application in my hot rod other than using the car dock for GPS.
I really was resisting the idea of a built in head unit or touch screen as I like the simple look in the interior and the dash is already cramed w/ engine and transmission computers / wiring. So I came up with hair brained idea of using the Droid as the music player and a Bluetooth reciever for a source for the stereo amp. I could have just used the audio jack on the Droid, but I would have to plug and unplug everytime and I didn't want to do that.
I got a bluetooth headphone set for $50 and disected the guts so I would have speaker outputs to run to the amp. One of the speaker pods has on/off, track, volume controls so I'll use that as a small hand held control.
I know there are probably a lot of much better ways to acomplish this, but I was getting really lost with all the high tech jargon and software being tossed around online and my head just hurt trying to sort through it all.
The right side had the controls and the left had the internal battery.
I hardwired the speaker outputs. The Bluetooth unit still needed the internal battery connected to work even with external power connected. I'll hook up a 12-5vdc power souce so it will get power from the car battery. I extended the leads for the battery so it can be concealed under the dash.
