There are plenty of ways you can go about monitoring your network performance, but this setup using a BeagleBone Black is always running and visualises your speed in a fun, colourful way. It lights up a tri-colour LED strip based on the current speed of your network.
The strip will light up partially with red lights for slow speeds, go about halfway up the strip with orange lights for moderate speeds, and light most of the strip with green lights for higher speeds.
All you need is a computer, a BeagleBone starter kit, a special LED strip and a few other components to get the ball rolling. No soldering or modifying of electronics is required to put it all together, and the step-by-step guide explains the minor programming necessary to get your speedometer running. You can also modify and adjust everything in the code provided. For more information on how you can build your own, check the link below.
