This Pong clock displays the time and temperature in score-like fashion
If you need to get creative with something useful, clocks are always great objects to hack together. One idea, in particular, is this Pong Clock from Brett Oliver.
Oliver’s Arduino-powered device is based off of a similar project by Nick Hall, and plays itself in Pong, winning and losing to show the correct time as the score. This version adds a temperature display, countdown timer, and an excellent enclosure made out of what was once a cheap jewelry box.
The results are excellent enough to place in a stylish kitchen or living room, and looks like an approachable build. You can check out the project in the video below and find more details Oliver’s write-up here.
