Songbird - May 2023 - Silicon Chip Online
This ‘Songbird’ is quick and easy to build, with a simple circuit, so it is perfect for beginners and even more experienced constructors. It sports an aptly designed PCB, and once completed, will burst into song. It is powered via two AA cells and ‘sings’ via a piezo speaker. by Andrew Woodfifield
