[sdiy] Eagle footprints

[Tim Ressel]

I have been burned a few times using downloaded library parts only to 
find they are wrong. Found out by burning PCBs, which means lost time 
and money.

If you download libraries ALWAYS check them. IF you are lucky enough to 
have a part that the manufacturer provides a .bxl file, you can use a 
program like Ultra Librarian to create an Eagle symbol. It may still 
need editing but the basics should be correct.
