Unveiling the Project’s Core At the heart of this project lies a carefully designed 3D printed robotic arm, brought to life by the synergy of Arduino and servo motors.

In this case, the 3D printer used by the Nixie clock project is a Prusa i3 (which is the same printer used to make the original Nixie tubes).

This design features a 3D-printed cube that balances using reaction wheels. Utilizing gyroscopic sensors and accelerometers, the device adapts to shifts in weight, enabling it to maintain stability.

It costs just a few bucks to print, making it an affordable and accessible option for young learners and classrooms. Dr. Mary-Elizabeth Brown is a concert violinist and the founder and director of the ...
