Santa Cap

A Santa cap is perhaps one of the easiest wearable blinky-flashy items because the cap has ample space to hold the controller while also offering a highly visible piece.
Materials in this build:
- Inexpensive felt Santa Cap purchased via eBay
- HeadBlinker wireless controller with 9-volt battery
- 12 RGB LEDs, wired in parallel so that all red, all green and all blue on on their own circuits. This requires only 3 channels to control all the leds, reducing some current draw and helping the battery to run longer.
- 12 RGB led carriers.
Assembly:
- Assemble the HeadBlinker controller, attach battery to bottom with double-stick foam tape.
- Solder the LEDs to the led carriers.
- Solder the carriers into a strip long enough to fit around the cap's white headband. Connect the strip to the controller and test.
- Poke holes for the Leds in the white fur headband; poke through from behind, tucking the connection wire down near the bottom of the headband.
- Drop the controller into the inside of the cap. When wearing, the top will be flopped over to the side and gravity will keep the controller in.
