Bought a whole bunch of led panels and built myself another useless gadget just for fun
There is a link to the project wiki in the video description for those interested. It's all open source, open hardware. I hope it will inspire or help other hobbyists looking to do similar things.
Gonna have two game controllers, audio in/out (amiga compatible audio core and visualization fun), midi in (for using as a visualizing synth) and ethernet for streaming video and madrix control (or network gaming with a sister project? wink wink). Software will be on an SD/MMC card.
So... yeah... that's a bout it - have a great day!
