Build Your Own LED Glow Poi

Spinning poi is an entertaining pastime, and LEDs can make a great addition to the experience. MilanDer built some LED poi of their very own, using a few maker staples along the way. A 3D printed enclosure is first created, using “clear” PLA that in practice produces translucent white parts. This acts as a great diffuser for the APA102 LEDs inside. The LEDs are driven by an Arduino Pro Mini, which is fitted inside the enclosure along with a buck-boost converter, lithium battery and charge board. Finally, a strap is added to allow the poi to be spun easily by the user.
