Light Painting Sash

This is a piece of wearable technology that I dreamt up on a cold and wet Saturday in February to use in my electric unicycling light painting projects. This project made use of my programming, electronics and sewing skills. The garment consists of a 144 individually addressable LED strip with a controller and 5 volt portable power source. The sash is designed to be worn over one shoulder.

The garment has been programmed with the following modes:

  1. Variable speed with automated hue cycling
  2. Variable speed with variable hue selection
  3. Variable speed with variable intensity
  4. Comet effect with variable speed and variable hue selection
  5. Rainbow comet effect with variable speed and variable hue selection
  6. Single position two LED effect with variable hue and variable positioning selection
  7. Single position two LED effect with automated hue cycling and variable positioning selection
  8. Twelve position two LED effect with automated hue cycling and variable positioning selection

The different modes are cycled though by pressing a momentary push to make switch. The speed, hue and positioning and intensity are controlled by two rotary potentiometers. The battery pack and pattern controller have reasonably long leads allowing them to be hidden away in pockets when riding the electric unicycle. The material in which the LED strip is housed was selected due to the way in which it diffuses the light.

A quick photograph as below – I’ll add some light painting images/video at a later date.

Light Painting @ Clapham Common Skate Park

This evening I headed out for a light painting session starting at Westminster, before moving on to Clapham Common Skate Park.

Neopixel Strip Light Painting Wand

Continuing my fascination with light painting, this weekend a strip of 144 neoPixels arrived in the post so I followed several tutorials to create two different light painting wands.

The first tutorial was on the Arduino Basics website:

The second was from the Adafruit Industries website:

Photographs of the results to follow…
