Things are going ok with this project.
A reminder of requirements:
- Play on composite video screens using 4 wire connection (from RPi)
- Play DVDs from DVDs, using USB DVD player
- Web interface for controlling the gizmo
- Play stuff from Airplay or equivalent
- Provide an in-car wireless hub so it's easy to get into from phones etc.
What remains to be done?
- Attach DVD drive, check that DVDs play
- This might require purchasing an MPEG-2 key from RPi - £2.50 :-p
- Connect composite video screen, see how that works
- Fiddle with Airplay, but I suspect this is going to hard with Apple's proprietary protocol
- Do some power supply testing - I'm getting a lightning flash symbol on the upper right of the screen, which is an indication that the power supply is occasionally inadequate!
- This should include in-car testing from a USB supply thingy
Then package it all up somehow. Marv.
I recall reading articles about powering a Pi in a car. In particular how to handle power off when leaving the vehicle. Can wreck SD cards. Will try dig out some stuff, probably comes down to using a powebank thing and a simple circuit to detect power outage on cigarette lighter to trigger a shutdown. My biggest problem would be keeping it tidy!
ReplyDeleteGood point! I have a 10AH USB battery I can use to check this out, as a power buffer. However, the power loss detector is interesting... I guess it could be just 12V from fag lighter reduced to 3.3V, applied to a GPIO pin! Probably need some time function applied to smooth the on/off/on effect.
