Any plans or pics for rotary interfaces.
Lilwolf:
You will not be able to build one for the price/time it will take. He has dropped his board price a LOT over the years hes selling them (and started gettng the board printed in mass).
So don't expect it to be cheaper... Or easy...
He does (or used to) sell a kit that you build your own. It saved 10 bucks or something and you do all the soldering.
Also, consider hotswappable control panels. Then the 24 inputs aren't the problem (the connection type is).

The interface is cheap to make. The most expensive part is the microprocessor which costs $3.50. I already have resistors, capacitors, connectors and a perf board. The total cost should be under $10. The whole project should only take a few hours.
SirPoonga:
BTW, the mk64 encoder does ls-30 also.

You need to get the PIC programmed as well. They are $3.50 like you said, but without the programcode AND the programmer device you won't get something that works.
rdagger:
I already wrote the code for the microcontroller. It is only about a dozen lines of high level and it took under an hour. Still, I wont know if it works until I get it into a chip.
I'm trying to decide now between Atmel AVR and PIC. The costs of both chips are now in the $3-4 range (for this project). I probably will go with the AVR because there are some very powerful free compilers and the chips supposedly run faster.
Building a programmer will take a few hours and probably cost $10-15. However, I will be able to use it in many future projects.
