It's a special day when hardware guys recommend something that is software. I apologize if this sounds like a bad infomercial at 2AM. Dropbox has completely won me over. If you are like me, and have multiple computers that need to share files, Dropbox solves the file sharing and backup problems. I installed Dropbox on my home PC and a little icon sits in my task bar. I've got files on my home PC like my Eagle projects, my excel files, my docs, and my various collections of C code. So I drag and drop these into a folder on my C: drive, a folder called 'My Dropbox'. Simple enough. Then I go into work and install Dropbox. A couple minutes later I've got a folder on my C: drive called 'My Dropbox' and it's got all the files that my home PC had. I've got 2GB free, to

Oh PCB layout. How you spite thee. What's a coaster you ask? A <a href="http://en.wikipedia.org/wiki/Beermat">coaster </a>is something that sits under a coffee mug (or beer glass) and prevents the vessel on top from leaving a visible ring on a table. It's also a name for a completely screwed up PCB.
