Since this post, of course, I've gotten (only slightly) fancier. I've got a set of eight LEDs, driven directly from eight GPIO lines (plus ground :) ). Fun only. And Perl driven. But my goal now is to hook up photodiodes so I can read my old paper tape reels I've had sitting in my house for 40 years...
