Want to replicate the Apollo Guidance Computer that first brought man to the moon?  Want to do in your basement?  In your spare time?  This original took the best engineering minds in the US in the 1960s.  Now, for your do-it-yourself pleasure, the complete plans, along with helpful guidance, can be found at http://starfish.osfn.org/AGCreplica/ .  Have fun! 

Great news!  Yahoo! has licensed the X1 desktop search engine for free download.  I've used the Google Desktop, Lookout (free from Microsoft), and X1, which used to cost $99 for a personal license.  X1 was by far the best.  It's search was blazingly fast, the index was small and the UI was the simplest.  Plus, it doesn't have the security issues of Google Desktop or the Outlook start-up time impact of Lookout.

I'll be downloading it as soon as it's released, comparing it to the full version of X1.  I'll let you know how it looks.
