Our major project for Maker Faire this year is an overhead matrix of Chinese lanterns, lit by new versions of our Satellite Modules and a new controller. There will be 128 lanterns laid out in a 16x8 matrix, inside a 20x10 foot canopy. The lanterns will react to music and we'll let the audience select visualizations and hopefully interact in other ways. It's going to look awesome!
However, we're really busy just building the thing. I've gotten the LED code working well, and have tested up to 25 frames per second streaming pixel colors from Processing to an Arduino to control everything, but coming up with neat effects takes more time than we have. Here's one I have made so far:
Therefore...I'm hoping that a few helpful Processing dabblers could download my existing code and try making some new effects. I've wrapped it all up in a matrix simulator as you can see in the Youtube video. Simply draw the effect in the upper 320x160 area, and it will be pixelized in the bottom half. The pixelized area is what will be sent to the LEDs, so I need effects that look good in the pixel area too. I have FFT and beat detection all set up, you just need to hook your ideas into that. Stuff with bright colors, simple shapes, and computationally forgiving will work best. Easy!
Once you have some neat effects working, just send the functions you created and any new files you added to . Try to send by May 19th...earlier is better. Make sure to add a comment crediting yourself! I'll figure out how to integrate everything. Then I'll release the full application, and LEDs will be on display at Maker Faire Bay Area on May 21st and 22nd. Stop by to admire your coding handiwork if you're in the area! We'll make sure to take video and post it later.
