Rotary encoder success

Dec 01, 2008 23:14

I've been working on the little rotary encoder gadget that I took along to last month's Dorkbot Bristol. It's a CD-ROM hub/motor, stripped out of a broken drive and repurposed. I've wired up the three hall-effect sensors to give a signal that represents the rotation of the hub, and connected it all to an Atmel AVR ATmega8 microcontroller. I've ( Read more... )

Those displays are annoying. All those I've seen so far are strongly modal: they're either doing "display" or "talking to the interface", but never simultaneously and they aren't even switchable via the interface. Seems they were designed to be undorkable!

I found someone's web page where they'd hacked a keychain-sized photo display -- and it turned out to be a 6502 architecture CPU in there! He got about 8FPS, sending photos as fast as they'd go. But I've not (yet) found anyone who claims to have made a photo frame accept, say, RGB or composite video.

A *what* in there?

I thought those things were obsolete a squillion years ago when I was coding on an Apple II (Z80 geek at heart). Mind you, I'm well impressed with your UK109.

There's a bunch of interface boards around (try Adafruit) for putting phone displays onto Arduino. Really must try and have a go at that sometime.
