Espruino device casing / presentation

Which country are you in?

I recently discovered electrical 'Junction Boxes':

• 65x65 http://www.screwfix.com/p/4-entry-junction-box-with-knockouts-grey-65-x-65-x-45mm/63295
  
• 88x88 http://www.screwfix.com/p/7-entry-junction-box-with-knockouts-grey-88-x-88-x-53mm/30356
  
  

They're cheap, nice-looking, mountable, and relatively waterproof. The fronts also just ping off if you need to get access to the innards (but you could probably screw into the side with a strange-headed screw like a pentalobe/torx if you wanted to stop people getting in)

For the sensors it might be worth making a rain shield to go over the top and protect them - I guess either 3D printed or just bent metal. You might also find that you can use the cloth they use on speaker fronts to help to protect the sensors a bit.

Otherwise companies like Farnell/RS/Rapid Electronics have a very good selection of tough boxes, but you usually end up paying a lot for them :)
