Designed by artist Néill O'Dwyer, the prototype for Megapixel has now been built by revolver.
We have built a low-budget prototype of the video wall using an Arduino board and a small array of RGB LEDs.
The video files are processed using open source tools such as Processing and the Java programming language. The images are deliberately pixelated. They are broken into a grid and the colours within each box are averaged.
This array of colours is fed into the Arduino board which allows us to address each LED directly via a custom built on-board C++ program. The system is not scaleable because of the limited outputs on the Arduino board, but the concept is proven.
We now seek opportunities to scale up Megapixel.
