A dynamically programmable 4 digit combination lock. All in one chip.

Archive: 7 posts


I have to be honest though, it could have been a lot simpler (90% less work) if I would have used selectors for everything, but I wanted it to be pure logic. Not to mention I could have used toggle chips for memory and a single binary decoder with a 4-way switch. It ended up being a lot of fun to make, aesthetically pleasing, but overall useless and overly-complicated .

Sorry, but the best I've got is an EasyCap, and even that is at my parents house (in another city). I have some more interesting stuff laying around, so I promise I'll post similar creations with either more snapshots or even video, but this one is not worth that much hassle.

A'ight. That's cool. You seem to be pretty dedicated to logic. I'd love to see what else you've got. 2013-08-09 03:03:00

This is a proof that logic has real aesthetics! I've always been fascinated from pictures like yours, though my logic skills are lousy!^^ Its somehow like a painting!^^

Thanks,

I'm happy to know others appreciate aesthetically pleasing circuitry There is indeed a magic to it, it wow's you with it's complexity, yet manages to present itself beautifully in a comprehensive manner. I'm such a dork -.-
