The device is being tested in-house (on the balcony actually) while enclosure is being prepared. Enclosure is made out of an old wood found on the street.

Why wood? - because of the chosen location of installation (more on this soon). It must blend with its surroundings so it doesn't reveal itself on a first or even second glance.

It will be impregnated with primer and painted over, essentially making it water-proof.
