I was browsing YouTube and decided to do some searching on the SX microcontroller to see what videos existed. I love to use YouTube to see the projects that others have created, especially for robots. Still images can only tell you so much, right?
Here is one project that looks neat. It is an array of LEDs for scrolling text and graphics, similar to the Robolympics medal sold by Parallax in the SX Tech Tool Kit.
There are many other great videos as well, just search around. Benjaminshinobi looks to have a set of videos based on lessons or experiments he was performing with SX.
