As the holidays approached and I was wearing my LED'tennae, folks complimented on them but identifying them as antlers. They just assumed it was somehow a Rudolph hat of some sort. That got me thinking, can I build antlers using the same technique? The answer is yes, with some modifications.

The build is basically the same. A little bit more material. A little bit more patience. The significant difference is with power. Since each antler has 3 LEDs, one CR2032 doesn't provide enough power. Two seems to work pretty well. However, this means the battery holder has to be thicker to hold the 2 CR2032 batteries.

I recommend reading the build for the LED'tennae. This Instructable will focus primarily on how to wind the wire around the antlers and then power them.

Step 1: Parts and Tools


This is the parts list for 1 antler. Double it to make two (a left and a right).

  • Chenille stem, qty 2 1/2
  • 2-pin Dupont connector, qty 3
  • wire, 22awg, red, ~2 ft
  • 3mm red LEDs, qty 1
  • 3mm green LEDs, qty 1
  • 3mm yellow LEDs, qty 1
  • double-stick foam tape or stick-backed Velcro
  • CR2032 battery, qty 2
  • Cap with 2 venting holes in the front

I chose to use 3mm LEDs instead of 5mm. They seem to consume less power. Having to already double the power and thus the thickness of the holder, anything bigger inside the cap would be a pain to wear.
