After a brief respite at the bottom of his wardrobe, Neil dismantled the laptop looking for useful spares and maybe some inspiration. He hit upon the idea of building a desktop computer that would fit in with the surrounding furniture, rather than being yet another drab black box. 鈥淲hat do you do with a 17-inch LCD panel? Put a frame round it,鈥 he says. 鈥淚t鈥檚 got to be different, so wooden鈥 pine to be precise. Add a Raspberry Pi 3B+ and my love of awful puns gives us Raspberry Pine.鈥

9. Singing Toilet

Hardware Components:

路 Raspberry Pi 3 Model B x1

It may be the ultimate bathroom experience: wall-mounted toilet rolls that 鈥榮ing鈥 various notes when the paper is pulled, thus creating an extremely pleasant and calming trip to the smallest room. But how did this very novel idea come to fruition?


Maker and artist Max Bj枚rverud explains that this custom installation was born from a request from a client: 鈥淔redrik 脰st at Snask (a creative agency) here in Stockholm wanted something for the toilet. I don鈥檛 remember how our conversation really panned out, but a week later I presented the first prototype. The build itself was quite quick, but it needed some iterations to find the best holder and roller. The most difficult part was to make it usable. They need to be able to switch toilet paper without a technician.鈥
