NASA's Spirit mars rover was supposed to have a 90 day mission, and has gone for over 3 years.  It's currently running over 13 times it's
lifespan.  How does this happen?  It's because their engineers are insanely OCD about building their stuff.

While the limit of my electrical skills is pretty much swapping batteries, reading this is amazing.  It's a handbook of the techniques that have produced some of the most impressive tech of the 20th century.
