CPX-1701

This is the adventure of the United Space Ship CircuitPlayground. Assigned a five year galaxy patrol, the bold crew of the giant starship explores the excitement of strange new worlds, uncharted civilizations, and exotic code. These are its voyages and its adventures.

Explore exciting new modes of propulsion by creating a really big vibrating motor. This Crickit project attaches a bunch of CD's to an up-cycled CD-ROM motor for a cool looking warp drive. Some popsicle sticks, NeoPixels and sound effects complete the space craft and it's now ready for your command, captain!

CircuitPython Code

This project is pretty simple, it plays some audio clips, and then lights up the built in NeoPixels and powers up the motor in time with the effects.
