I converted the LEGO NASA Artemis Space Launch System (SLS) set into a fully functional alarm clock powered by an Arduino Uno R4 WiFi. A stepper motor drives the original launch mechanism so the rocket physically rises at alarm time, and a hacked megaphone plays rocket launch sounds instead of a normal buzzer. The clock runs on a custom web interface for setting alarms and syncing time. The whole project is open source, and I made a full YouTube video explaining the design, electronics, and...
