Uno R4 Wifi I Turned the LEGO NASA Artemis SLS Set Into a Real Alarm Clock With a Motorized Launch Sequence
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 build process — https://youtu.be/Qg7JDSrsakI?si=kV0Cu2O6Z9C5bAoE

You should take some government money that I have set aside and let me pay you to develop arduino projects for my high school classes.

Hahahaha, this is fully open source! So if you wanna recreate it, it shouldn't be too hard!! Love sharing projects like this in hopes of other people making them as well!

If you don’t have the time that’s fine but i’m looking for a microcontroller/PCB enthusiast to help develop projects for middle and high school robotics classes.
