Creating an animated LED light wall with Raspberry Pi, Python, and APA102

This project was another large window installation for the Urban Art project in Great Falls, Montana.  I wanted to create something with LEDs that would have visual impact similar to the 1 meter POV displays, but with no moving parts.

First attempt to display a PNG image.

I set out to create a large POV display for a local quarterly art installation called The Urban Art Project, in Great Falls, Montana.  The space is 8 feet wide, 5′ 8″ tall, and around 17 inches deep.  Two 1 meter rotors fit nicely in the space.

LED Light Suit

This LED light suit was created for Halloween, 2014, and was developed over a period of 2 weeks.  6x 5 meter waterproof white LED strips were used, along with an Arduino Pro Mini, piezo microphone and amplifier, all running from a LiPo battery.  The strips were sewn onto track pants and jacket, and worn with snowboard boots, gloves, and goggles.

Custom Arduino firmware offered several modes of operation, including sound activated, pulse, steady on, and off.  A remote in the sleeve allowed control of mode, brightness, and sound sensitivity.  The firmware was created in the Arduino IDE.

A custom PCB housed the Arduino Pro Mini and 6 Mosfet transistors to drive each of 6 PWM channels at up to 2 amps.  A custom case was 3d printed for the electronics which fit into the front pocket.
