r Set the red light brightness, values are 0 and 128. b Set the blue light brightness, value range is 0 to 128. It comes with both the source code, and a pre-compiled binary. The result is “rslight”, which you can download here. And after ripping the USB HID code out of Audio Hijack Pro, that’s what I built. For this I just wanted a simple command-line tool that could be invoked from a shell script. So with that problem tackled I moved on to the next one, actually controlling the RadioSHARK’s lights programmatically. ![]() You can get a third color, a weird shade of purple, if you turn both blue and red lights on at once. The RadioSHARK is a USB-controllable light! It’s a bit expensive to use just as a light bulb, but if you already have one, why not? It even supports does two colors, blue and red. But then while working on RadioSHARK support for Audio Hijack Pro 2.5, it hit me. They make USB toothbrushes, but not USB lights. The hang-up I always ran into with this was finding a USB-controllable light. In fact, it’s been done many times before, and for things other than software projects. ![]() Once something like this is set, knowing the status of the source tree is a simple matter of glancing at the light. ![]() If everything was ok, the light would stay off, but if something failed it would turn on. All the projects would be automatically built, and their unit tests would run. The setup would be fairly simple: whenever a change is checked into the source code repository, an automated build (and test) would be triggered.
