I found a source for cheap arcade buttons and went on a kick of adding them to everything I could. I started by slapping this box together with and arduino and bluetooth module I picked up from sparkfun
The first thing I used it for was to control itunes playlists on my music server. Each button sent a control character of a serial connection to the server via the bluetooth module. A script living on the server triggered the appropriate applscript actions.
- battery powered
- arcade buttons that can be arbitrarily mapped to various script actions
- easier access for battery replacement
- battery save mode and/or power switch
- convert to sending osc messages
- publish code to github
