For anyone looking at the Galileo I’d suggest looking at the Arduino Yun as well. I found the Galileo to be quite a chore to get working including having to make the special serial cable, getting the better linux distribution, buying the usb/serial cable, the challenging performance of the arduino side. On the other hand I had the Yun up and going in no time at all. In conclusion, unless you have a compelling reason for using the Galileo I’d suggest you consider the Arduino Yun.
Is there an RDS library or sample code around? I don’t want to re-invent the wheel.
I paired one of these with a Arduino Yun to get http (Web Service) access. It worked great. It was a bit of work sorting out how to route it all through a level matching circuit but it works great. If you have a web page to access the tuner you can change the radio settings from the browser on your phone (or another computer, of course). I only needed one of the level conversion boards to get it to work.

BTW, I see detailed documentation someone has posted:
This thing really does work quite well and you have access to all the cool camera stuff like exposure, white balance, sharpness etc. The software does NOT allow you to composite any text onto the image which is too bad because sometimes it’s handy to put a time stamp on images. The circuit board is pretty small and the mounting holes are small as well. A bit of a challenge getting this mounted to anything and the ribbon cable is not as friendly as a non ribbon cable would be. You can’t really drill the holes much bigger because some are close to traces and/or components. I mounted mine to a piece of acrylic and tapped a hole for a tripod:

The simplest thing to do might be to use a relay to energize your solenoids. That way you don’t have to monkey around with electronics. The relays from SainSmart don’t require any special wiring and can be powered from an arduino or RaspberryPi. If you’re just using the solenoids for a quick on/off you can wire the solenoid through the relay to the power source without any other wiring. If the solenoid is going to be “on” for a while you will probably need a resistor in line to dissipate some the power. You can probably find a relay board (e.g. SainSmart) that can control 8 things for under $10. The problem is that a relay makes a small click sound, but a solenoid does as well. If you listen to the video below, you can here the relays/solenoids in the background. I’m currently using the Sparkfun 5V relays for a music projects, they’re pretty small but work quite well. “Push” type solenoids are often easier to use for music stuff.
Here is a project I did using a RaspberryPi, relay board, solenoids and a Korg Koass Pad. This would work just the same with an Arduino. I’ve used various solenoids as percussion sources, they work very well.

If you want to get really simple, scrap the arduino and get a doepfer midi to gate, then you can get a usb to midi and camera connection kit and run the whole thing from your iPad! No software to write, just midi (you can sequence your solenoids using Ableton Live or MaxMsp. I have this setup working with the 5V sparkfun relays.

What should the SD card have on it (besides mp3 files)? Does it need the patch files as described in Bill Porter’s documentation?
Is there a way to access the MIDI capabilities of the VS1053B chip?
-The amplifier can really generate some volume, you may want to put a control on the amplifier ( e.g.: MP3player.setVolume(vol, vol) from a potentiometer on A0; Indeed, as the notes say, bigger speakers to generate bigger sound. I connected this to a pair of 6" automotive speakers and it is definitely loud enough for a ‘room level’ listening application.
