A quick Weekend Project https://alainsprojects.com/pssp-pi-single-song-player/ And the whole thing in german http://awallelectronic.blogspot.lu/2016/12/pssp-pi-single-song-player.html
2 years old project. Still annoying ;)
I've built this to make people in my office happy 🙂 The idea is to build something like this "days without accident" panels. Each time somebody will push the button, the counter resets and Last Xmas will play. All the details can be found @hackaday.io
Metalwork
Working on a new project. Found a solution, to attach a hexagonal metal distance sleeves to a motor axle.
