I've been away for a few days and it's been great to come back to a few new bits and pieces! The Raspberry Pi 3 is here, as well as the lights. I completely forgot that the new Pi only takes a micro SD card, so I'm moved all my pics and vids from my phone SD onto the computer so I can format it!
Sadly no sign of the components for connecting the 2 together yet, but over the course of the weekend I've managed to rig up the Raspberry Pi with a some test LEDs (one of dubious brightness) and played around with various software to get them to work in a sound activated way.
The best I've come up with so far is Lightshow Pi at http://lightshowpi.org/ which does most of the stuff I was interested in programming - hopefully there will still be some room for customisations! That software will control a ridiculous number of channels though. Here's a little demo of it in action...
I've also embarked on a crash course in graphics programming (and C++ come to that, it's been a while) - looking at the SDL library but might need to go into GLES programming for better speed on the Raspberry Pi. I also need to work out how to get both Lightshow and whatever graphics routine I come up with to both listen to the same piece of music and be reasonable in sync and responsive.
I've also got a car stereo to wire in (but no speakers yet). It's one of those Chinese import ones but it'll play video, does Bluetooth, and has a composite video out, so hopefully I can use it for something useful that isn't just making noise - perhaps a second projector source? I spent some of this afternoon fitting it (well, attacking one of the cupboards with a drill and a saw until it fitted) and started replacing some of the ancient 12v striplight fittings with warm white LEDs. They give a much nicer light at a lower power rate, but it's highlighted that we really need a new leisure battery in the caravan :-(
Don't forget there's still time to donate to the project over at http://www.crowdfunder.co.uk/sensory-caravan
