Build it Yourself: Internet Speedometer
Track the speed of all the bits and bytes that pass over your local area network and transform that data into blinking tricolor LEDs, powered by the BeagleBone Black.
There are plenty of ways you can go about monitoring your network performance, but this setup using a BeagleBone Black is always running and visualizes your speed in a fun, colorful way.
