MacroFab Design Contest: Blink an LED Sponsored by Mouser Electronics

Welcome to the MacroFab “Blink an LED” Challenge, sponsored by Mouser Electronics. This design contest is all about blinking an LED or LEDs. Build something that blinks an LED or LEDs on command. How you power and program (or not) it is entirely up to you. We want to see some amazing blinking LEDs and for you to document it all. Include A-Ha moments, lessons learned during experimentation and more.

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

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.

We have prizes for four different categories:

  1. Pragmatic Blinky – Useful ways to blink an LED(s) – example projects could be roadside assistance lights, camping lights, or some other project that using a blinking LED(s) is practical and useful
  2. Most complicated blink – Can you build a Rube Goldberg machine that blinks an LED?
  3. Wearable blink – A Human (or other animal) wearable device that blinks an LED
  4. MacroFab Engineering Podcast Favorite: Podcast co-hosts, Stephen and Parker will discuss and pick their favorite project on the podcast
