DIY VCO - Shaping Sawtooth to Square

Learn how to build an analog Voltage Controlled Oscillator (VCO) from scratch in this 27-minute video tutorial. Explore advanced techniques for shaping sawtooth waves into square waves, adding variable pulse width output, and improving oscillator stability. Discover the use of thermistors, fine-tuning knobs, and how to achieve modular-conform volume levels. Follow along with a detailed bill of materials and step-by-step explanations of component functions, including temperature compensation, op-amp basics, and waveshaping techniques. Gain practical insights into analog synthesizer design and electronic circuit theory through hands-on demonstrations and sound tests.
