Accidentally making a Lightsaber instead of a Glowstick

Over on the facelesstech blog, the project concept was a glowstick with LEDs. Things turned out a bit different:

So you know how you have an idea for a project but you don’t quite how to execute it. I wanted to make an electronic glow stick using ws2812, I wasn’t sure how I was going to do the ws2812 part because normally they come on a PCB or in a 5050 SMD package. This is when I found the ws2811 8mm LED’s. Follow long with me on how I came to make a light saber and not an electronic glow stick.

An excellent post on going from concept to design and build with software on GitHub.
