I found the mint tin limiting though if you’re adding wires & parts to your circuit, plus I have always felt a little iffy about putting prototypes in metal enclosures.
So here’s a printable case for mint tin-sized circuits like the Menta. It has openings for the DC power jack and the FTDI cable.
Included is a 25mm high version and a 35mm high version. For larger or smaller sizes, it’s pretty easy to stretch the case bottom to fit your size. Also you can design in some holes for pots & switches on the top.
The case top has little clasps that grab onto the small nubs on the case bottom to securely keep the case on.
Adafruit MENTA – Mint Tin Arduino Compatible Kit, Includes Mint Tin. Introducing the MENTA, a portable minty Arduino-compatible project that fits into a common mint tin. We took our super popular Boarduino series, and wrapped it with a prototyping area into a rounded PCB that slots directly into an Altoids-sized metal tin. We included everything you expect to jump-start your project:
DC power adapter jack with polarity protection
Beefy 1 Amp 5V regulator and 250mA 3.3V regulator for 3.3V devices
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
