The Screech Owl is based on a new custom shield for Arduino Leonardo which provides connections to a linear potentiometer for position layered with a thin film pressure sensor for aftertouch. This approach has previously been used to create a couple of DIY designs that have been described online, but nothing that is commercially available either as a complete product or in kit form. The new shield design and open-source software makes it simpler for non-electronics-enthusiasts to build and understand.
