Candy Plastic Cartridge Reuse As A GoPro BacPac

MewPro PCB is sold without casing. We describe here how to make an attractive enclosure from “Frisk” by yourself.

Parts List

Frisk breath mint candies in plastic cartridge
This is sold at any convenience stores found across Japan. Unfortunately, Frisk packages in other countries are different from ones in Japan, so you might want to import them from Japan.
MewPro w/ SMD parts and Herobus connector (soldered)
In order for MewPro PCB to fit in Frisk, Arduino Pro Mini must be soldered by yourself.
Arduino Pro Mini 328 3.3V 8MHz
Genuine Pro Mini or any clone will do.
Wires and solders
and some skills…

The essential part is the Frisk plastic casing. Its depth is 10.5mm and this is almost the same as GoPro BacPac’s 10.0mm!
