Looking for a bidirectional 2 pole rotary switch

<< < (2/3) > >>

drventure:
Hmm, So with a cheap rotary encoder and a couple flipflops, it's doable

Found this circuit...

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

Looks like it'll work. 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?

drventure:
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.

I'll have to check that site out.  :cheers:
