The Useless Machine is a gizmo that turns itself off when you switch it on. But how? Is there a little stubborn person in the box playing a trick on you? Is it magic? No, it's a set of switches with a small motor and you get to put together! By building the kit yourself only you will know the secret of how it works. When you show it to your friends and co-workers, keep them guessing - after all you built it, it's your secret!

Invented in 1952 by Marvin Minsky at MIT. The useless style boxes, in various forms and with different names such as "ultimate machine" and "Leave Me Alone Box" have inspired curiosity and fun for more than half a century. Popularized in recent years by Frivolous Engineering, Solarbotics as well as many DIY versions on the internet. The SpikenzieLabs Useless Machine is our take on the basic concept, designed from the ground up in style, mechanism and ease of construction.

After many months of design, we are really excited about the clean look and ease of assembly of this kit. We received a great number of requests for a DIY soldering version for our original Useless Machine (no soldering required)
This one is identical to the original and you get to solder our unique PCB as well.

The Useless Machine has these great features:

  • Easy to assemble
  • Soldering required - Easy through hole parts
  • Clean laser cut acrylic design.
  • The motor and switch assembly is one piece (The motor, arm, both switches, LED lights and screw on battery terminals are all part of the same activation unit.)
  • Two color LED arm lighting (Green LED while the arm is going up and red while it is going down)
  • Robust and smooth hinge design

What's included in the kit?

  • Laser cut acrylic case, arm, and motor mount.
  • Motor
