Product Description

The Conehead is the next series of our critter based PCBs (past ones are The Lady, The Gent, and The Monarch). It's an audio circuit that synthesises the sound of a cricket. It uses three oscillators interacting with each other to create the distinctive sound. Using a small speaker and a phototransistor, the cricket will change its chirping frequency depending on the amount of light it 'sees'.
