Alarm clock shades – Automatic window shades

Automatic window shades, Anupam writes-

It is nice to wake up from natural sunlight (instead of being jarred awake by a loud buzzer). While there are alarm clocks out there that do this with an artificial lamp, I thought it would be cooler and much cheaper to make my own. Also, instead using artificial light, my alarm clock will open my window shades letting in natural light.
