Macro Fab Design Contest Useless Machine

MacroFab Design Contest: Useless Machine Sponsored by Mouser Electronics

By The MacroFab Team  |  May 31, 2019

Welcome to the MacroFab “Useless Machine” Challenge, sponsored by Mouser Electronics. The contest is all about creating the most useless machine – we want to see some amazing useless machines and for you to document it all. Include lessons learned during experimentation, design challenges, and more. You need to build something that is completely useless to society. How you design, power it, and program (or not) it is entirely up to you.

You can do this in several different ways, here are some examples:

  • A device that sends tweets of the temperature of mars for tourists
  • A clock that isnt even right twice a day
  • GPS that tells you where the furthest bathroom from you is
  • Kids Toy where a button press makes an animal noise but none of the sounds are right: The cow says woof

We will also have guest judges to determine the fate of the contestants. Judges will be announced via social media. Be sure to follow @MacroFab & @MouserElec for more information as it becomes available.
