Hi all,
I want to share my idea for a self made enclosure for my netduino plus.
I took the container of an old 8mm video tape and with an utility knife heated over a flame I cut off the excess plastic shaping the shape of the connectors (power, ethernet, etc ...), then with a file I finished edges. Found space in the container also an Xbee radio module and the wathdog circuit (thanks to Mario Vernari who shared the circuit here on the forum).
I hope it can be helpful to someone else.
