Hi Guys, Just a little something I whipped up with parts from both Dick Smith and Jaycar. Scrolling displays are nothing new, but hopefully some of the demos shown here have not been done before. Sine Wave Message Scroller Demo: http://www.youtube.com/watch?v=Q_pF8WSTVGU Three Part LED Display Demo: http://www.youtube.com/watch?v=tIhrOQJ8j5g I'd like to make a much bigger one with port expander chips, but LEDs are so expensive. I'm thinking on expanding on the idea of a playable game, and maybe making a duplicate of the circuit with different colour LEDs. Cheers, Art.
