Experimenting With Light On Apple Notebook Computers

John Gruber:

Amit Singh — who first published example code showing how to use unsupported APIs to use the motion sensors in Mac notebooks — now shows how to get readings from a Mac’s ambient light sensor and how to get and set the brightness of the backlit keyboards.

How long until someone writes a hack to use the keyboard backlight as a CPU monitor?

This particular Linked List entry is pointing Amit Singh’s experimentation with the Light Sensor API. The API allows access to the readings of the ambient light sensor, the LED brightness value of the backlit keyboard, and the display brightness.

Gruber’s CPU monitor could happen. Parhaps somebody could link brightness to system temperature? In either case, there should be an option to make the keyboard (and/or screen) throb the warp core on the Enterprise as CPU usage temperature increases.

Of course, I could see this eating into the PowerMate‘s market. I mean, who needs a flashing knob to notify you of email when you can have a flashing keyboard?
