The “Final Exam” Box Prank – Rick Roll your classmates with #CircuitPlaygroundExpress from #Adafruit

Via Reddit, u/gbh218 describes a prank box they made for final exams using two Adafruit Circuit Playground Express boards:

We decorated a box with “Final Exam” and “Do Not Open” explicitly written in the front and side. This is to encourage any tempted students to look inside the box. Once the box is opened up, a written sign reading “You’ve been De Vinck’d” will flag up with a “Rick Roll” loop playing until the box is closed again. Any student who decides to open it will become victim to our version of being “Rick Roll’d” – what we like to call: “De Vinck’d” (Our professor’s name).
