As promised, the foam board construction – well, a first step anyway:
The “folds” are a bit ugly this way, I’ll hide them on the inside using V-cuts in the next version.
Room node and battery pack included for size comparison. You’d think they fit easily inside, but the battery pack is surprisingly tricky, given that the room node needs to stick through the slanted side facing outwards.
The “walls” are also a foam mockup I’m using to avoid having to use an actual ceiling corner :)
Here’s how I intend to to place everything inside:
The battery pack will be attached to the top, i.e. flat against the ceiling. The room node will be mounted such that the PIR sensor sits in the middle, sticking out.
