Spirit Halloween Proton pack Neopixel LED holder

thingiverse

I wanted a brighter Large bar graph for my proton pack, which I purchased from the Spirit of Halloween store. https://youtu.be/_dIlRnc0tK0 The design fits neatly into the existing space - it's a press fit that is very snug, so no glue is required. Simply pull off the old lens and LED, and insert this new one. I used a blue plastic duotang, which cost under $1, for the lens. The electronics I used to power my 12 neopixel strip (144/meter is what I used) are an Arduino Nano. Unfortunately, the Neopixel strips consume too much processing time on the processor to have a continuously changing display, so I'll be using three processors in the pack. One for the bar graph, one for the power pack lights, and one for everything else - including other LEDs that monitor and sound out alerts.
