Stacking Arduino Shields

So what if you need two shields on your Arduino?  Try using wire wrap sockets.  The wire wrap bit will fit into the socket below (snugly), and the socket bit will serve as a socket for the next shield up.

From Digikey, I picked up two SAM1125-06-ND (CONN RCPT .100" 6POS TIN WW) and two SAM1125-08-ND (CONN RCPT .100" 8POS TIN WW) to replace the standard header pins in a SparkFun Protoshield.  That is where I will be placing the support circuitry for the "Breath" project.  On top I will have a LadyAda Ethernet Shield.

Here are the results:
