Here’s how to make a fuzzy heart that purrs when you hug it! Rachel writes –
This project is a pillow, which I’ve chosen to make in a heart shape, with a secret surprise inside. When you hug it, squeeze it, sit on it, whatever – it purrs to you!

I have made a couple of these and I leave them on the sofa for unsuspecting visitors.

I’ve been interested in touch and pressure sensors in soft toys for a while now, and this pillow is about the simplest sensor/motor combination you can do. It consists of an outer fabric shell, a battery/motor assembly, and two fabric switches that act as pressure sensors.

I will be showing these and some other variations off at the Maker Faire this May 19th and 20th with my collaborator, Annie Shao. Come see them in person!
