While practicing Yoga on your own, it can be helpful to use an interval timer to let you know when you have completed a certain pose. While there are myriad apps that offer this functionality that play a sound when the time is right, there is something wonderful about the sound of a physical gong being struck.

This project uses a CLUE board to display poses, proximity control to start your pose timer with the wave of a hand, and a solenoid striker to chime a singing bowl.
