These days, a lot of phones don’t have audio jacks anymore. It can make it hard to listen to music if your favorite headphones aren’t already wireless-enabled. Minty Tunes solves that problem, combined with a little Altoids tin flair.
Yes, the long and the short of it is that this is a Bluetooth audio receiver built into a tin of mints. The build is relatively simple, hooking up a cheap Bluetooth audio decoder module to a lithium-polymer battery. This is paired with a TP4056 battery charger IC to allow the battery to be topped off easily. It’s all then wired up and stuck in everyone’s favorite hacker electronics enclosure.
For those who aren’t fans of wireless earbuds like AirPods and the like, it’s a useful solution for listening to music from a smartphone. As the builder notes, it’s also a great way to play music over a hi-fi or car stereo with an aux port. Alternatively, you could always build your own pocket MP3 player from scratch.
