Pro tip for anyone who is trying to mount an Arduino Uno project inside an Altoids tin: put it in upside down! The centre point of the power socket is quite tall on the board; mounting it upside down allows you to bore the hole toward the bottom of the tin and thereby avoid needing to gouge a chunk out of the lid to allow it to close flush.
You can see my first attempt in the background, before I clued in to the fact that a little patience with the tapered reamer goes a long way. I’ve lined the bottom of the tin (and will line the lid) with cardboard so it doesn’t short and I might even stuff a couple of sheets of bubble wrap in to keep everything snug.
Now what the hell am I going to do with all these Altoids?
