Homebrew PCBs

I often use .1" pitch Berg connectors as test points. Very convenient. I 
use a flexible wire with a Berg connector on one end (shrink tubing 
around it to prevent shorts) and bare wire on the other that I grab with 
an alligator or other clip.

In fact when I put together my M128 board from http://www.bdmicro.com I 
put headers in that are long enough that the bottom part fits in a 
breadboard and the top ones accept connectors. Sweet.
