Mint tins can be used for a lot of great projects. They are just big enough to be stuffed with some great electronics. This Mint Tin Alarm by Aaron from x2Jiggy is a great example of this. The video has a great beat and check out the cool schematic, no hard to read symbols here! Check out the Instructable Article for more details.
“Combine a mint tin, piezo siren and some basic components into a personal alarm that’s both functional and visually pleasing. This design involves connecting a 12 volt A23 battery to a piezo siren through a toggle switch and a tact switch. The toggle switch is used to arm the device (preventing accidental activation) and the tact switch activates it.”
