LED Helmet

This cheap and cheerful LED matrix helmet was loosely based on the masks worn by Daft Punk in the music video for the track titled “Something About Us”.

A Johnson decoded decade counter (4017) was used to cycle through the columns of the matrix, while 2 shift registers allowed individual LEDs to be illuminated in the column determined by the counter. An Arduino Uno was used to control the counter and shift in the desired pixels to form an image. These images can be played in quick succession to create the illusion of motion.

The LED matrix on the right is driven by the same chips and is there for a duplicate of the left hand matrix.

It is hard to make this look pretty, and it is even harder to look through.
