NeoPixel 60 Pixel Ring Sci-Fi Visor

thingiverse

I finally decided on something to make with Adafruit's 60 pixel rings I bought a while ago. Designed over a weekend. MADE TO FIT OVER GLASSES! Added a new half piece for smaller print beds, or beds that don't handle big prints well. This is a very simple build! Takes less than an hour to print, next to no touch-ups are needed. Just add the neopixel rings and an arduino and your good to go! Some simple soldering required. https://www.youtube.com/watch?v=loCIGUPjD60 This project has an optional addition of an encoder to the arduino which lets you change the speed and brightness of the visor on the fly. I measured the current of the default speed/brightness to be about 150 mA, so most batteries will last a long time with this. Build materials: 2 x small rubber bands 4 x NeoPixel 1/4 60 Ring (https://www.adafruit.com/products/1768) 1 x 3d printed white plastic visor 1 x portable battery-pack or MintyBoost pack 1 x micro-controller, I am using a teensy 2.0 1 x adjustable eyeglass strap (http://www.amazon.com/Chums-Universal-Eyewear-Retainer-Black/dp/B003CJSE5O) 8-10 x small zip-ties 1 x Perma-Proto Quarter-sized Breadboard PCB (https://www.adafruit.com/products/1608) Optional: 1 x rotary encoder w/ push in button (https://www.adafruit.com/product/377) 1 x 3d printed rotary encoder knob (http://www.thingiverse.com/thing:51020) Total cost is about $100 if you are buying everything from scratch. (including the neopixels, battery, arduino, eyeglass strap) Resources;https://learn.adafruit.com/larson-scanner-shades/softwarehttp://www.thefrankes.com/wp/?p=2660http://www.pjrc.com/teensy/td_libs_Encoder.html Instructions Printing: Print either one full piece or two halfs Print it with 2 perimeters an 0% infill No supports are needed I used sharpie to block the light from shining into my eyes on the inside of the visor, but chrome or shiny paint might be better, maybe even silver sharpie. Electronics: See the gallery for wiring diagrams in the gallery for the neopixels with or without the encoder. I sawed off the power rails of the perma-promo board to make it the height I wanted, then soldered everything together and zip-tied to the side of the visor. NOTE: Follow exactly the wiring diagram in the fritzing pictures, the picture of my circuit has been modified so that I could mount the encoder on the underside of the pcb Arduino code is in thing files, all dependencies included.
