The Amazing Lego DAT Tape Changer
lizardboy writes: "This is for the Lego loving computer geek with large backup needs. The Lego DAT Tape changer. It can be interfaced with any platform supporting Lego mindstorms. I have used it with OSX and Linux using dump and NQC with some custom shell scripts. It also works under a Mac OS 9 using Retrospect and RCX."
Lego is obviously good for prototyping these sorts of products, but it would be cool if there was a Lego compiler that would scan the completed model and produce parts by eliminating all but the minimum number of inter-connections required for efficient assembly, and replacing the Lego connectors with more permanent ones.
