Now that’s just cool. This is a tiny black briefcase, with working hinges, and slide switches on the front like a real briefcase.
It’s the perfect size for a battery board and a few smaller circuits parts. You could fit an accelerometer and logging circuit, and toss one in the ocean… but then you’re probably going to waterlog the circuit and fry the battery.
So it’s probably a good idea to leave this case to in-pocket, on-desk type circuits that you just really want to cram into small spaces.
