This is my take on the Arduino platform.
It plugs directly on to the side of the breadboard bringing all the data and analog pins directly on to the board with the 5v and ground rails.
Its my first home made double sided board and in fact only my second home made pcb using the toner transfer method. There are a few bits I can improve on the pcb layout such as movong more of the traces to the top side of the pcb. It took two attempts to get the top and bottom mask aligned but finaly I got them almost spot on.
