Automatic harmonica plays simple tunes

An engineer by the name of Jon Sorkin has come up with one of the coolest ways to play a harmonica – by not playing it. He created a contraption that allows you to play songs on the harmonica with the push of a button. Just select a song, and press play. The machine was made by a handful of electronic parts, a couple of harmonicas and an air compressor. One of the harmonicas even has had its reeds reversed so the machine doesn’t need to suck air to play a different set of notes – it only needs to blow air into the right holes to play a song. Admittedly it won’t replace a human harmonica player (at least for now) but it does a decent job. The instructions have even been posted online if you’re interested in building one for yourself.
