Circuit sculpture uses soldered brass rods as components in electronic circuits.

This project shows you the tools and techniques you need to get started through a simple touch-reactive heart that uses an Adafruit GEMMA M0 and CircuitPython.

While this project is deliberately simple, the things you can create with Circuit Sculpture are limited only by your imagination & patience. For more inspiration, consider taking a look at some of Mohit Bhoite's works.

Are you new to using CircuitPython? No worries, there is a full getting started guide here.

Parts & Supplies

Please be sure you get two CR2032 Lithium batteries for the battery pack.

In addition to the parts shown below, you'll need some double-sided foam tape and hot glue for assembly.

The brass rod is available at many hardware stores. This project is designed to use just one 1' brass rod, leaving you with extras for experimentation.
