I made a spinning LED sphere that has 72 addressable RGB LEDs on a 3-spoke "propeller" that spins on 2 axes. This is still a work in progress, as I need to design the final control board PCB so that it's not a bunch of breadboard wires, but the main physical assembly is complete.

* Got and learned how to use a 3D printer

* Learned parametric CAD in Fusion 360 to design the main assemblies that the motors, slip rings, and propeller attaches to.

* Learned how to design PCBs and had them made

* Re-learned soldering and did SMD soldering for the first time

* Learned some ESP32 programming to control it with bluetooth (I have plans to have a robust live-editor so you can control the light patterns from a tablet - currently on pause)
