{{Project
|shortDescription=Display where a user pulls a handle on a rope and one random sound is played
|longDescription=The [[Selkirk Marine Museum]] asked us to build the electronics for a display where the visitor would pull a rope, and one of four steam whistle signals would randomly play. The physical part of the display would then help the visitor to understand what the whistle signal meant.

We set up the mechanism to pull the rope to trigger a switch and the programmed and installed the electronics to play the sound.
