Ulrich Habel shared his implementation of BlinkStick API with jRuby.
The working processing example for the blinkstick, however, was working without
any driver installions. This implementation uses the
hidapi library as driver. I looked through
the processing sample applications and rebuilt the BlinkStick.jar from it with
out any modifications. I gave jRuby 1.7.3 and jRuby 1.7.11
a shot and it worked. Most of the tricky work to find a proper way to access
the Java classes and how to set it up.
