The Useless Machine - With Counter


Elmwood Electronics has stopped accepting orders. This product might be available at PiShop.ca. Please check this blog post about our recent team merger.

This version is just like other Useless Machines, but with an added bonus. It's two soldering kits in one!

Solder The Useless Machine control board, then go on to solder the counter circuit. When you've finished construction, you've got a Useless Machine, that can count exactly how many times it's been Useless!

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.

  • Really cool on board counter that counts to 9999 uselessnesses.
