Announcing the Open 7400 Logic Competition 2012

Posted on Monday, September 3rd, 2012 in 7400 contest, contest by DP

By popular demand the Open 7400 Logic Competition is back! Build a kooky, intriguing, or over-complicated project that makes use of a discrete logic chip and you could score some amazing sponsor swag.

7400 TTL, 4000 CMOS, logic built from discrete transistors, or logic implemented in a CPLD – it doesn’t matter. Just have fun and impress the judges with your logic-themed creation. Get inspired by last year’s entries.

This year kicks off with a fantastic prize: 2 Analog Discovery mixed signal tools from Digilent:

Analog Discovery is a 100 MSPS twin channel oscilloscope, 2 channel function generator, 16 channel digital logic analyzer, and 16 channel digital pattern generator with a USB interface.

The competition runs until October 31, 2012. Submit your entries and get more info here.

Like last year, the Open 7400 contest is an open source, crowd sourced competition. Every day we’ll announce new prizes and celebrity judges. If you’d like to get involved please drop us a line.

Good luck on your project!

What’s this 7400 logic stuff all about?

The 7400-series and similar families are logic chips that contain the individual building blocks of digital electronics:

The 7400 series contains hundreds of devices that provide everything from basic logic gates, flip-flops, and counters, to special purpose bus transceivers and Arithmetic Logic Units (ALU).

    mmm, what to build… Will have to go see what 7400 chips I have, but last year’s competition seemed tough, how on earth do you compete with entries such as that…

  2. Matseng says:

    Haha :-) I’ve already got an idea of what to do. But unfortunately I don’t think it will be worthy of the first prize…

    That is an awesome prize. I love competitions like this because they show me that there are so many real thinkers out there.

    I need to rethink my idea because I am wondering if it is much more common knowledge than I realized.

    So cool! I’m really excited about this year’s competition and I already have a couple of ideas of what to enter.

    I really appreciate the sponsors and their adding of incentives to this competition. The more sponsors and more/better prizes there are, the more participants there’ll be, and the more fun this will be. A personal shout-out goes to Tin Can Tools, the sponsor that provided the prize I won last year. Thanks Tin Can Tools!

    Many thanks in advance to this year’s sponsors for helping bring excitement to the competition!

    My workplace just threw out an old AMPEX ADO 1000 system that had a 5V 200 AMP (yes…200 AMP power supply) to run a huge amount of logic. All that was wrong with it was an old 7404 gate gone bad. $250,000 (back in 1984) became my source of fresh 74xx and 4xxx logic. Now what to build…hrrrrm. Any ideas? I’ll send some chips your way and share the prize (if any). ;) Good luck!
