I'm going back to extending the original hat project. Among other things I will be using an LED Matrix (8x32) rather than try to wrap a Neopixel strip around the hat.
Modficiations/extensions to the original project:
- RaspberryPI 3+ or maybe a Pi Zero as the core processor as both support Bluetooth AND WiFi.
- Plastic cowboy hat that is lighter and more comfortable (temperature wise)
- Inverted lampshade as the base for the matrix.
- Camera (front- or back-facing or both)
See BOM for some of the materials.
