The next step in my Mardi Gras hat is to create a layout of the mask to determine how much wiring I need for components and the sizing on the circles. I'm going to be using silicone coated wire from Adafruit to connect my NeoPixels and other parts.
I used a 2D CAD program (QCAD) to lay everything out virtually. It's a lot easier for me than pencil and paper. I can play around with ideas until I get everything the way I want it.
This video shows you the layout process and my conclusions. I've ordered all the necessary parts from Adafruit based on this layout and they were very inexpensive. I'm looking forward to working with the electronics in my next post.
