Update your files soon as new changes have been made. The LED ring features 40 NeoPixels controlled by an Adafruit Trinket powered by 4 AAA NiMh (or 3 AAA) batteries and printed using a Witbox with 1.75 PLA filament at a layer height of 0.2mm or less without support, and with 2 perimeters and 20% infill. It is inspired by a tutorial on the Adafruit website. You will need an Adafruit 16 NeoPixel ring, an Adafruit 24 NeoPixel ring, an Adafruit Trinket 5V, an Adafruit PowerSwitch, three 40cm lengths of small wire (1.5mm diameter max), 30cm of heat shrink tubing, eight M3 nuts, and two M3 x 6 hex screws. Additionally, you will need four M3 x 10 hex screws, a soldering iron, a hex driver, wire stripping tools, super glue, and to follow the Adafruit tutorial for installing software on the Trinket. First, cut the wires as per the instructions, being careful with the soldering behind the rings due to limited space. Connect the wires according to the diagram provided in the tutorial, making sure the connection is compact. In Arduino IDE, copy and paste a specific sketch while changing a line of code. Connect the Trinket to your computer and download the modified sketch. Disconnect the USB cable and unsolder the wires. Next, attach the LED rings to the front piece by drilling eight holes for cable management. Arrange the rings and install the small ring with cables going behind the headpiece. Glue it in place and create a "U" shape with the wires under the front piece. Solder the wires to the outer ring and glue the outer ring in position, ensuring the wires do not cross each other. The installation is ongoing, so stay tuned for further steps.
