I keep seeing these spiffy Olympia InfoGlobes, and wanting to hack them into a display for my computer. If you're not familiar with them, they're a neat little globe, with a spinning "persistance of vision" blue LED array, which lets them display messages that appear to hover. Now, I've done some searching, and I've only found one article on hacking this thing - it's remarkably complete, and they decide to use a TIGER computer for "pressing" the buttons. This is a pretty good solution, but I think that there may be a better one. http://www.wilke-technology.com/applications/appn_071e.zip is the zip archive with a PDF with pics. What I'd like to do, is take full control over the LED array (it's only 8 LEDs), to do other effects. There are several POV plans out there - most of them handheld, and run by PICs. Ideally, I'd like to hook it up to a serial/parallel port, and have the computer display things on it, like a 1x30 LCD. Preferably, any solution should be as low-cost as possible - the TIGER, for example, is $49. Without a programmer. Ouch.
