If you're interested, you can dig through the list archives (I don't
have a good enough memory to summarize it all ;). I can answer the
encoder question though. The board will work with rotary or linear
optical encoders, and will support backlash compensation for rotary
encoders in the near future.

As far as building my own encoder, well, I've got exactly zero
experience with this. If you can come up with the strip, the
electronics aren't too bad. You'd also need to make a mask for the
reader head, but if you can handle the strip, the mask is about the
same. Boy, build the card, build the encoders... just build yourself
a mill and you'd be the king of the DIY crowd! :)
