24 LED (2.1") Neopixel Glasses for Arduino nano by Fer451

Last crawled date: 3 years ago

This is a remix of 4 existing files in order to make a pair of self contained Neopixel glasses using two 24 LED Neopixel rings, and an Arduino Nano processor. Updated Lenses File 2019-12-27
Hopefully I fixed the broken polygon issue that some people's slicer's didn't like. It's the "Fixed" file. I also included the .3mf file in case that can help.

I realized the lenses file started the print off the heatbed, and it made the front of the glasses "less attractive" since the supports needed to be trimmed off. That s now fixed. The new file has holes on both sides for the wiring as well in case you'd like to put the processor on one side and the battery on the other. The centre hole is also larger to accommodate the ribbon cable. I also updated the firmware, it does what the video shows and more.
I tried to hide the wiring inside the frames as much as possible, the bridge between the two rings is hollow for that purpose. Unfortunately one side is heavy, so I added an elastic to the back to keep the glasses on securely.
If you decide to use a different processor, you can mirror the left arm and add what you need instead of trying to remove the box on the right arm used to house the Arduino Nano.
Needed to build:
3D printed parts, - Print one -Glasses new, one left arm, one right arm, and 2 pins
2x 24 LED Neopixel rings- by Adafruit or on Ebay
1 foot - 3 conductor ribbon cable
1/8 inch drill - to clean out the holes in the arm for the arduino wires
3/16 inch drill - to clean out the holes for the arm pins
7.2v LI battery, or a battery of your choice that will run the processor and LEDs (I used 2 3.7v 180mah batteries in series)
connector for the battery
Nailfile emery board - to sand the edges that will be close to the face, and to round the pins so they are easier to move.
soldering iron
hot glue gun - to secure the rings in the glasses
Arduino Nano with no pins.
You will also need to program the Arduino Nano with the source code. You will need the Adafruit_NeoPixel library. I reduced the brightness in the code so that you don't burn out the Arduino 5v regulator. They are still bright enough. Solder the tx wire to pin D3.
The code is from Adafruit.
