Here's a new video of our LED cowboy hat, showing the layout in RocketLife LightDesigner. The first shot shows the LightBoard Mini LED controller, which was small enough to fit in the groove at the top of the hat. A "lipstick" USB battery powers everything. View on Twitter »
I used the circle drawing tool to create the layout. (Notice the option in the ••• menu to reverse the LED direction.)
Here’s a photo of the inside. The battery and LightBoard Mini are Velcroed to the top of the hat. I bent the Dupont pins at the end of the LED wires 90° to save space. For the power wires, I used slightly thicker header pins, which should grip even better.
