Flickr member kc6qhp created this impressive enclosure for an Arduino Pro -

I made this housing for an Arduino Pro that will control my waveguide relay in my 47 GHz radio. This housing is made from 6061 billet aluminum. The cover is held on with a dozen 0-80 screws. There i a cutout for the programming connection and a filtered DC feedthrough. Later I will add other connectors for the servo and transmit/receive switch, etc. 

Sturdy! – more pics on Flickr.

    Not only sturdy, but also screened against all that high-intensity 47GHz microwave radiation that the thing generates. That’s probably the reason why there are so many screws holding the lid down, to maintain good RF-tight grounding all the way around the lid.

      Actually the 47 GHz signals are very well contained in waveguide and are of relatively low power, so the Arduino is safe from EMI. The reverse is of more concern though, noise from the Arduino getting into the 47 GHz by means of modulating the power supply voltage. The housing might help a little, but the filtered DC feed through will probably take care of it. To really isolate the Arduino I would also have to shield the servo control cable and servo motor itself. The good news is that everything else in the radio is in boxes like this with even better shielding.

    Nice work as usual, Tony!

    What made you decide to use a cutout for the Arduino interface pins instead of a shielded connector?

    How do you plan to get other signals in/out of the box?
