My first post here; I thought you might like to see my Volumio project.
(apologies for the somewhat messy installation of the parts in the blue case - the next stage of the project is to fit all the parts properly into a proper high-tec enclosure with a custom built loom to tidy it up)
For a long time I have wanted an HDD based high quality audio player for the car. I wanted a system that could be remotely powered up and controlled from home, a system that held a mirror image of all my home music collection, and a system where I could send new music files to the car via wifi without ever having to use physical media (memory cards) again. I wanted multi-format compatible audiophile quality music playback. I also wanted the system to be able to run in the car on its own power without draining the vehicle battery. I couldn’t find anything off the shelf that met my requirements so I built one myself based around the Rpi and Volumio. I’ve had it working for a few months now and it works great. I don’t like messing about with smartphones or tablets to select the music to play once I get in the car, I like to be able to do this from the comfort of my home. So my normal routine prior to starting a journey is:
Look out of my house window at the car in my drive
Press the key fob to boot up the system. Look for the led to light up in the rear window which tells you that the system has powered up.
wait for arrival of “carlink” wifi hotspot to confirm that system has booted
connect to “carlink” hotspot with tablet or home network pc then connect to “volumio” player
browse files or playlists ans set them to play.
(whilst system is powered up and within range of home network new files can be sent to the car wirelessly)
press play and the system is set. As soon as I get in the car the music is already playing!
I have had the system working from a hotel room where I could see my car in the carpark.
As well as ‘pushing’ files to play in the car via volumio, you can also ‘pull’ files from the car and play them on your tablet or smartphone provided you are within wifi range of the “carlink” hotspot.
I’ve included a ‘system diagram’ at the end of the photos.
RPI B+ with HiFiberry dac
5v & 12v voltage regulators
TP Link MR3020 travel router
Seagate 2TB HDD
433 mhz remote control system and keyfob
12v battery pack (ups) - allows system to run on its own for about 2 hours, and/or charges via cigar lighter socket.
maintains power during engine stop/start preventing system crash.
The system is very easy to install in the car - I fit the blue player box underneath one of the seats and the battery pack goes in the glovebox. The only connections to the car are the ‘cigar lighter’ 12v outlet and the car headunit audio aux in input. I just push the cables underneath the mats. What do you think of my system? There are several enhancements to the system that I am planning, but my programming skills are very limited. What I would really like is bluetooth control of the volumio system track advance/reverse/pause/skip etc on my tablet via a little steering wheel bluetooth transmitter. So as I can control the system whilst the car is being driven - playing with a tablet whilst driving is obviously not practical! Hopefully somebody here may be able to help me
