  • DIY: Waterproof and coldproof box for raspberryPi

    Hi there,
    I'm running on a raspberryPi 3b with the FlightAware Pro Stick Plus dongle connected to the SIRIO SPO-1.09-6 antenna.
    I was wondering if any of you folks built a waterproof case for the above.
    I live in Poland so in winter there is a lot of snow and rain, temperature can be up to -20Celsius (even for a few days in a row). I live in a flat and have a storage box outside which can cover the set from the rain/snow but I'm not sure how it looks if it comes to the high humidity and minus temperatures. I believe that the raspberry and dongle can produce some heat which in the closed box can keep the temperature around 0 Celsius.
    If you have any tips or maybe created similiar box I'd love to see it.
    Thanks!

    Do not go for totally hermetically sealed box. Because any cable can bring in moisture, and than you will get this:

    Therefore, leave some small holes, and bring the cables inside from the bottom, not above like in this picture.

    Furthermore, I just posted the graph of my Rpi, on similar location, but with a bit warmer climate (-10 to +40 C):

    So, you see, even when I have two 3mm holes in the bottom of the box, and cables are a bit loosely going through the holes, it still manages to be quite warm. Works for almost a decade now.

    The box above is Gewiss watertight box, pretty common. I think it is this one: https://www.gewiss.com/ww/en/product...000088.GW44236
    Feel free to use whatever you like or have on hand. This one is a in the middle of price range, I am using them for 20 years now. There are other products with similar quality and even better price. Of course, if you go for all-metal, the price will be way higher, but you do not need all-metal case.
    Anyway, IP55, and sometimes, if location is under some cover, even IP45 can be good enough.
