    Dongles Overheating When Placed Outside In Warm Weather.

    Dear all,

    Just to advise now that the warmer weather is finally coming to the UK and your Dongles are placed outside of your home. This can also assist others around the World in warm climates too.

    To keep my signal from any loss of dB. My Dongle is placed outside my home, in a little black project box attached to my mast to protect it from the elements.

    However, since our weather has started warming up, I have noticed over the past couple of days, that when the sun hits my project box (my project box is facing West), the inside of the box get to over 40 degrees Celsius and the Dongle stops working and when it cools down, it's fine again.

    I have made an adaption to my project box and so far, it has stopped it from overheating and continued working.

    What have I done?

    If you have an old Car Windscreen Sun Reflector that you no longer use. Cut a section of this an place around the project box but do not block any air holes you have created - my air holes are in the bottom of my project box.

    As stated, my Dongle is in a project box, yours may be encased in something different but the applied principle will be the same.

    However, please be aware, that as this is reflective material. Please ensure that any sunlight that gets reflected off it, DOES NOT flash your neighbours, their houses or drivers of motor vehicles, bicycles. As this could cause injury to their eyes, accidents on roads or even fire to their homes (magnifying glass scenario)

    If this doesn't work for you, you could always try white paint as suggested by Amper.

    So far, so good but I thought I'd share this with you all.

    Kind regards,

    what did you expect from black box. I have light gray electrical outdoor box. Inside i have fr24 box + some other equipment and no overheating whatsoever.

    I have wondered if people using project boxes could use heatsinks like these http://www.ebay.co.uk/itm/261258338799 for cooling.

    Mount a length inside the box connected to a length outside the box using thermally conductive bolts as heatpipes ... obviously seal the bolt holes with silicone to prevent water ingress into the box.

    Put the fins vertically for best airflow.

    Sounds a good idea Pete but wouldn't the reverse happen (the outer sink heating the inner sink) when hit by direct sunlight rather than cooling?

    My idea is working great, as the reflectiveness of the Sun Screen is keeping my Black Project Box cool. Besides, it's all I had at the time of build.

    Hey Pete, how did you get your Range Diagram off ADSBScope?

    Dump1090 on on the pi needs extra parameter "--net-ro-port 31001"

    ADSBscope on windows from http://www.sprut.de/electronic/pic/p...html#downloads (I'm running version 2.6, I see 2.7 is available)
    adsbscope network setup set to ...
    PortNumber: 31001
    URL: IP address of Pi on home network
    Data Format: Normal
    Start Raw Data Client (right hand button if the 3 network buttons)

    Yes but is overheating and you have to put mirrors on it?!?
    Why not paint the box white?

    Whilst you may call them mirrors. Agreed, they are reflective but it's like Solar Film you use on a Telescope to do Astrophotography but it also has a honeycomb centre to dissipate the heat.

    As my initial thread. The temperature was reaching 40 degrees Celsius inside my project box but with the near clear sky we've had today, with temps reaching 19 degrees, higher than previous days when my box was reaching 40 degrees inside. Today, with my cover applied, the inside of my box only reached 16 degrees Celsius. A vast improvement on previous days and my Dongle was working happily.

    However, painting the box white would also help too, I imagine.

    Why the interrogation Amper?? Are YOU the FR24 Police??

    Do YOU not think I would have taken that into consideration prior to installation??????????
