In the Spring of 2017 I started researching how to build my own unique and interesting electronic sound-making devices. There are many DIY circuit schematics out there but I was particularly drawn to the CMOS-based circuits for my creative work. CMOS-based synthesizers or Lunettas are chaotic sounding in nature which is great for improvisation. They provide a node-based approach to building complex systems and interactions. They are fairly inexpensive to make and provide a nice platform for teaching basic electronics, synthesis, and sound design. The links and pages below document some of my experiences exploring CMOS circuits.
