Neopixel ringlight with cold shoe mount

This is a bit of a tweak to the Adafruit Neopixel ringlight project that can be found at https://learn.adafruit.com/3d-printed-camera-led-ring/overview

I liked the idea but I wanted to change the way the light mounted on the camera. I wanted to move the control box away from the lens and switch to a end-of-lens mount for the light. I wanted to add a way to switch colors, as using neopixels only for white light seemed like a waste. I also wanted to build-in the battery charger so that charging was easier.

So, I redesigned the housing and added a color select button and a USB li-po charger. All of the parts are friction fit, with the controls in stacked boxes within an enclosure with a cold shoe mount.

The parts used for this were:

24 LED neopixel ring: https://www.adafruit.com/product/1586

500 mAh Li-po battery: https://www.adafruit.com/product/1578

Mini li-po charger with usb port https://www.adafruit.com/product/1905

5v adafruit trinket: https://www.adafruit.com/product/1501

Small slide switch: https://www.adafruit.com/product/805

6mm button: https://www.adafruit.com/product/1489

Code is at https://github.com/jwitting/ringlight

I used a cat6 cable to connect the box and the ring. It was 4 conductors but i only needed 3. Any 3 conductor wire would work great. The wiring for all of it was a little tight in the enclosure but I managed to get it all fit in.

You will also want to flush cut your solder joints on the micros so they fit flush against the bottom of the enclosure.

The light is designed to friction fit onto a 55mm UV filter. If your lens has a different size it will not fit.

Print the front piece of the light with clear or translucent filament. All parts should print flat with no supports and reasonably quickly.
