Open 7400 Logic Competition

at 12:50 am. Filed under Contests


The Open 7400 Logic Competition is open and waiting your creative entry. I am not even sure the last time I slid open my drawer that contains my various 7400 chips I did see my TI 7400 yellow data book the other day. The thing I used to love about troubleshooting a circuit built with 7400 parts is that you could easily confirm a bad chip hunch in about 5 seconds by swapping it out.

Judging criteria and categories

Entries will be judged for:

  • Originality. A smart new design that inspires
  • Documentation. Schematics, theory, pictures and/or video
  • (Mis)use of 7400 logic. Show us what 7400 logic was (never) meant to do
  • Technical prowess
  • Build quality
  • Imagination and creativity”
