What to do with a spare computer?
mixmax: I have an old IBM X21 that served me well for many years, and is now enjoying its retirement in a drawer. I'm thinking about bringing it back and putting it on the steering console of my boat (Live on a boat) where it should perform the following operations:- control lighting, I'm looking into installing RGB LED's and so it would be ultracool to be able to have a program that can actually control the LED's, with different shades of colors, turning down the light when the sun goes up, etc.-  monitor engine vitals. A friend of mine has done some really cool small wireless  data recorders that can be used (http://dzl.dk/projects/electronics/102logger/102logger.html)- power usage. When I'm sailing everything runs on batteries, so I really want to monitor how much power I'm using and how much I've got left.- Charts. I'. thinlking about a webbased application that shows the boat in the middle of Google maps, so I know what's around me when I'm out sailing. There's usually 3G wireless when you're close to land.- Music. Last.fm when I'm on the net, mp3's when I'm out to sea.
