Need help with the idea, alternate perspective!
Ok, the Apple TV in car project created more problems than it solved. I had to have the ATV, and a wifi router, and the original PC, and I still couldn't get the connections to work for everything so I'm scrapping that plan :) ATV is going back in the house where it belongs and works so well. I can also remove the HDMI switch and wiring from the glovebox as well (it was VERY crowded in there).
I have an Airport express on the way, which I will also hack to run off 12V (quite easy) and has the optical output I didn't know it had so I can integrate with my audio system in the car. Airplay should work fine through it from both Itunes and the Ipad.
Quick breakdown of what is in my car. Car PC runs media storage, itunes (now) and controls the car functions through Fusion brain (once it works). Airport express, connected via ethernet to the PC. Ipad 2 connected via wifi to Airport. Iphone 4 running MiWi to serve internet access to these things. That last part is my problem.
For Airplay and the apple itunes remote to work, the ipad has to connect to the airport express wifi, not the iphone wifi (internet access). Can I share the internet connection from the iphone, through the computer to the airport, to the ipad, and still have airplay work? I couldn't get this to happen using the netgear router (which wouldn't bridge wifi OR create an NAS from a USB drive, both reasons I bought it). Am I missing an easier solution?
I want to downsize the car PC, to something that uses very little power and only runs the fusion brain and related car / security functions. The current one uses too much power to stay running 24-7. I think even a small pandaboard running linux could handle sharing the internet connection, from the phone or any stable wifi connection it could find, but I'm not sure.
Is anyone running a similar setup?
I just want to get in the car, and be able to airplay audio from the ipad or iphone or friends iDevices, without hassle (or wires)!!
