I added the limit switches to the mouth. I managed to find 2 identical switches with long levers which made them easy to install. A dab of superglue gel, and tada! I now have feedback whether the mouth is open or closed. I am holding off on installing the speaker yet. I stopped at a thrift store and found a pair of USB powered speakers for $5. It would cost that much in parts to make my own amp. I may just gut those and use them. Not sure yet, they also make handy prototyping speakers as I can power them right off my breadboard.
Anyway, attaching pictures of the limit switch upgrade.
