About this model

A fun 3D printed Useless Box with a countdown timer and a fully functional alarm clock. Flip the switch and a countdown begins, accompanied by beeps that get faster as the timer approaches zero. Just before the countdown ends, the box opens and a mechanical arm comes out to flip the switch back off! Besides the classic Useless Box behavior, this project also works as a real digital clock and alarm clock. You can set the current time, program the alarm time, and use it as a unique desk clock. This project combines 3D printing, electronics, Arduino programming, servos, and a bit of humor. ▶️ Watch the project in action on YouTube: In the YouTube video description you can also find the Arduino source code and the complete electronic schematic/wiring diagram needed to build the project.
