As many of you have mentioned, there are a lot of projects that are built with their own microprocessors, and are simply overkill. Here’s a reminder that we can do some pretty fun stuff light synchronized light shows without going overboard. This light show is controlled directly via the printer port on a computer. Sure you can’t un plug it and run it free standing, but you can build it for roughly $20.
[Asier] pointed us to this video of his PC-PIC II acting as a peripheral to his EEepc. You can see him playing pong, using it as a musical input, and even a video game controller. This project seems pretty nice, though we would like some more information. We tried digging around in the “projects” area and couldn’t find anything.
