A nifty computer vision application by Tom Wyatt of London Hackspace keeps their space tidy with Open Source Hardware boards BeagleBoneBeagleBone and ArduinoArduino:
BeagleBone project spotlight: Dirty Dish Detector
Dirty Dish Detector to help keep the hackspace sink clean. The system alerts users when a dish has been left in the sink for too long, ensuring you’ll get all of those dishes cleaned up before napping ensues. The Dirty Dish Detector uses a webcam above the sink, hooked to a BeagleBone open-source computer, based on TI’s Sitara AM335x processor. The computer runs the HoughCircles function in OpenCV to detect circle-shaped items like plates, classes and bowls. BeagleBone then sends a signal to an Arduino, which deploys different alerts (based on how long the sink has been full) to remind people to clean up their dishes.

What other clever computer vision projects have you seen that run on a Single Board Computer?
