Currently, I'm building a new bed for the wife. To pay homage to the great Tim Allen, who some would say is the original hacker, I'm not stopping there... The style of bed I'm building is a platform bed with a ledge that goes around the foot and sides. I'm going to put LEDs under that ledge and turn them into a "smart" night light. The idea is to have some pressure sensors on either side of the bed that will detect when someone gets up. The system would then check the ambient light to determine if being on is necessary. I plan on using an arduino to control everything. This also opens up the possibility of monitoring sleep patterns and logging the data.
