My heart box is a play on the old game operation, except with this twist: you’re operating on yourself (or a friend). First, you place the heart rate sensor on your ear. Then you pick your instrument, and try to pull your heart out of the box. If you’re successful, the heart continues to beat pink. However, if you hit the side of the box, the heart turns blue and a small pancake motor (attached to the back of the heart) buzzes. I liked working on this project a lot. It would be fun to make a large box version with more than one body part and multiple kinds of sensors.
Here are some images of my heart box:
And heres a video of it blinking:
