Discosaurus | RGB dinosaur costume

This is a remix of the spikes by metalnat and adafruit I saw the LED spikes a couple of years ago and I knew I wanted to make something out of it. But I also wanted to modify th design to hide the wires, put in some powerful addressable RGB leds and have them controlled by an arduino. This can be installed on any type of clothing (but be aware you will need to put holes into it). You can get very creative with the arduino code, make it react to music, have it cycle a rainbow and all kinds of other stuff. You can print everything out of white or translucent PLA but if you are able to I would suggest printing the spikes out of both PLA and flexible.The bottom houses nuts and needs to be rigid but the rest of the spike will be more resilient if it is printed from flexible filament. In terms of hardware you will need : - two M3 nuts, two M3 screws and large washers for every spike - a ws2812b RGB LED strip (or anything similar) - a 300 ohm resistor (to smooth the control signal) - an arduino nano (or other small micro-controller) - a bunch of cables - a 5V PowerBank to power the system (6000 mAh gets me over 5h of continuous use) The standard scale has a 0.4mm wall thickness (single extrusion), I've also added a 0.8mm version Big thanks to Loïc Jumel for the pic
