Create Your Own Auto Dimming Lamp With Sleep Timer
Sometimes when you are going to sleep it is nice to turn on the light, but having full brightness is not good. On Make, they show you how to build a self-extinguishing lamp with a built-in sleep timer.
The idea here is pretty simple: turn on the light and over time it will start to fade at a given rate. It takes a little effort to create this for yourself, but the end result is a rather unique little fixture that you can tweak however you want.
