The Useless Machine Kit

Build your very own useless machine. Switch it on and watch it automatically switch itself off. On, off, on, off — get hours of entertainment!




What's a useless machine? It's a machine that you turn on and it turns itself off. Why on earth would you want one? Because it's so darn entertaining! The Useless Machine started out as a simple Instructable with a video, which quickly went viral. Since then, the video has been viewed over 8.4 million times and the machine has been featured in Make: magazine and on the Colbert Report!

Now you can build your own Useless Machine with the Useless Machine kit. It features a laser cut acrylic case with a black acrylic "finger" and four metal hinges. The kit was designed with beginning makers in mind and features a custom circuit board to make soldering the electronics a breeze. Expect the assembly to take about an hour, and the fun to last indefinitely!
