How to Make a Lightsaber with NeoPixels #ElectronicHalloween

We posted about this tutorial back in January and thought it would be a great halloween project! From instructables user caitlinsdad:

So I was reading up on the Adafruit blog and came across Gewfy’s make of a mini 3D printed lightsaber . So I says to myself, “That’s not a lightsaber, mate. This is a lightsaber…” And I have a bag-o-Trinkets, 5v and 3v ones and I am not afraid to use them.

Well, time to investigate further and read up on what he had to offer. I always wanted to make a lightsaber and with the technology available today, it makes it easy to recreate things. I know enough about electronics to be dangerous so this project might not be too hard to tackle. I wanted to make a full size one. Besides, I nae have a 3D printer.

He offers the code for the Attiny85 which he used to build his Neopixel wand. Hmmm, I think I should be able to pull that over and use it in the Adafruit Trinket which I have. I also have some Neopixel strips from my Halo Cortana LED scarf. I’ve got some experience with soldering and working with those Neopixel strips.

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
