I have been wanting to do something special and different as a display. Last year I did a lot of looking and found something I thought I could achieve, Peggy 2.0 from Evil Mad Scientists. This is a 25x25 monochrome LED matrix that is powered by an Arduino and the LED's are driven by 2 LED current sinking IC's. I like this for one simple reason, a user figured out how to display a video feed at a good frame rate on this device. As this is an open source system I downloaded the schematic and built one myself (on veroboard) and created a small (3mm LEDS) matrix to test it on. I am now testing different LED types to figure out the ones I will use in my outdoor display matrix (1m x 1m). Turns out that getting the video to run on this setup was a lot more difficult than I thought. The person who did it originally, did it on a Mac and the software they used had no equivalent on Windows (which is what I have). But by looking at heaps of examples I have designed a processing script that will work. Now I come to my dilemma. I want this video display to be part of a standard light string display that is controlled by a computer. Am I going to have to write my own sequencing system to use the video? Or can the sequencers control other programs? Or do they have a scripting language that would allow me to run my video from inside the sequencer?
