Eurorack Modular Synthesiser

Modular synthesiser with a DIY VCO

My first PCB design project, pictured below, was a discrete analogue VCO for a eurorack-style modular synthesiser. I designed and constructed the PCB and front panel at age 15. This module contributed to a larger system pictured underneath, which was entirely soldered and assembled by myself from kits, and featured a custom power supply and laser-cut enclosure
