The St. Andrews Heritage Centre asked us to build the electronics for a display where the visitor would be able to listen to the awful noise the ungreased wheels of a Red River Cart would make as they turn.
To make it a bit more interesting, the noise would be triggered by turning a model wheel mounted to the physical display, as supplied by the museum. We set up a hall sensor circuit to detect the wheel turning, and an Arduino to detect the hall sensor signal and use this as a signal to start playing a the squeaky wheel sound on an MP3 player.
During the initial discussions about this display we also built the prototype of a wooden, analog foley device to make wooden squeaks. The museum ended up building one of these as well for the display.
The museum has a virtual tour of this display.
