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
- Green power LED, red blinky LED on pin 13
- ISP-6 standard reprogramming header
- FTDI interface plug to connect an FTDI Friend or FTDI Cable
- Female header set so you can plug standard Arduino-compatible shields in.
- Theres four mounting holes if you want to attach it permanently to a box or plate
- Massive prototyping area so you can have the finished project all fit together in a protective box.
- Four rubber bumpers to protect your table from scratching, and the PCB and parts from the metal tin
- This pack even comes with the mint tin itself!
Comes as a kit of parts, this is an excellent beginner project, with step-by-step instructions even for someone who has never soldered before. A soldering iron, diagonal cutters and solder are required to complete the project. Youll also need an FTDI adapter such as the FTDI Friend or FTDI Cable to program it via the Arduino IDE.
