HOW TO – Rotary dialer PIC interface

Randofo writes –

I have found myself with an abundance of rotary phones. In fact, they’re everywhere I look. In hopes that I may someday see less of them, I’ve begun taking them apart and re-using the parts for other purposes.

For some reason I got it into my brain that interfacing the rotary control with a PIC chip would be a good idea. I can only think of a couple of vague uses for it at the moment and none are particularly useful, but I hope to do something cool with this in the future.

    This would be a nifty replacement for a standard home alarm keypad.

    Or, as a “numeric keypad” for a manual typewriter converted to PC keyboard.

    ooo I see a steampunk design coming up.

    Damn, yet another project I’ve been tinkering with for months, done to completion by someone else! My project was based around a little 8-pin PIC and only two of the dial’s wires (the one NO switch). I got as far as cobbling together some PIC assembly, but the reference material I had on hand didn’t cover interrupts well enough.

    I really need to stick with one project at a time. But every new idea seems so much cooler than the current one…

    What I wanted to use it for was a a steampunk MP3 jukebox. Well, not really steampunk… what would you call 1920s retro-tech? Macassar-punk?
