Whatever kind of maker you are, whether you’re a baker, a mathematician, or a hardware aficionado, Pi Day is a fun opportunity to do a themed project. Our Pi Day contest just came to a close, and we got a ton of clever, creative entries. Although we could only choose one grand prize winner, we want to take this opportunity to highlight the batch of awesome runner-up projects that made our decision so hard.

Count to Pi
Kirby G made a fun wooden enclosure for his Raspberry Pi Zero-powered memory game. The premise is simple — the player enters as many digits of Pi as they can remember until they enter the wrong digit, at which point the display will read “Game Over” and tell you your score. What a fun way to practice your memorization skills! Nice job Kirby!
