This week’s How-To comes from our newest contributor: Logan Williams. This simple guide will show you how to build a digital synthesizer that generates and manipulates square waves. Your synthesizer will have one oscillator, which produces a variable pitch controlled by a potentiometer, as well as an LFO which modulates that pitch at a variable frequency.
The part count for this project is quite low, and it can be built for under $20. Finding the Parts The first step in building this digital synthesizer is to procure the parts that you will need. Not Pictured Tools Note: The potentiometers and audio jack must be either taped or soldered to 22 AWG solid core wire. Creating an oscillator Before we can begin with the digital synthesizer, we must generate the correct voltage. The most basic circuit in any synthesizer is the oscillator. The problem is that it oscillates much too fast. To build the oscillator, assemble the schematic below on a breadboard. Controlling the oscillator Creating an LFO.
