Open 7400 Logic Competition

The Open 7400 Logic Competition brings awareness to open hardware and software, and fosters understanding of the building blocks of modern integrated circuits. What can you build with logic chips?

Build a kooky, intriguing, or over-complicated project that makes use of a discrete logic chip and you could score some of the sponsor swag below.  Get inspired by last year’s entries.


This is an open source, crowd sourced contest. More prizes will be announced every day as new sponsors join the contest. If you’d like to sponsor the contest, please drop us a note via the contact form.


Call for sponsors coming soon!
