My most advanced version of the system to date is up and running. Now I have a webserver hosting a web interface on the Raspberry Pi that allows a user to connect wirelessly with a device and in a browser, browse through my record collection and select a record. I also started to play with the TouchOSC app and making an interface on an iPad more for busking along to music or making pretty light shows.
These new features were demonstrated in the first video I uploaded about my shelf. This is the first time I'd shared this much about the project with the public.
