Hmm, So with a cheap rotary encoder and a couple flipflops, it's doable Found this circuit... http://basicelectronic.blogspot.com/2006/08/rotary-encoder-converter-circuit.html |

maximic.com has tons of chips. one of over 9000 of them has to be a rotary encoder interface... and free samples to boot! ;D |

Your low time is a little long so you'll end up turning the knob further to get the pulses you want. Watch your signal inversion. If whatever you're hooking up to wants a LOW signal to indicate a button press such as the iPac, you need to pull the signal off of pins 6 and 8 instead of 5 and 9. But never mind that, doesn't the iPac support rotary encoders directly? |

Doesn't look like the IPac would, but the Optipac would. It's 40$, but I'd need to get an IPAC or hack a keyboard anyway, so the optipac just might be the ticket. |
