DIY Electronics Guides

As part of our mission to help others build their own synthesizers, we have created a number of DIY Electronic Guides on a variety of subjects.

Eurorack Power Guide

Eurorack Power Guide Power can be tricky. Most of us come to modular having never used a bi-polar power supply, and now we have to measure and understand the dark art of power. To try to clear up this confusion, I've written this Eurorack power guide. That...

Resistors: DIY Guide

  Resistors are one of the most common electronic parts that you’ll use, and their primary purpose is to add resistance to a circuit. The higher the resistance, the lower the current will be in the circuit. Typically a resistor is used to either limit current or...

Capacitor Conversion Chart

Eventually in your DIY Synthesizer journey, you'll come across a situation when you'll have to convert between uF, nF and pF. Paper and electrolytic capacitors are usually expressed in terms of uF (microfarads). Mica capacitors are usually expressed in terms of...

How Potentiometers Work

Potentiometers are the components beneath the knob that actually do things. This article will teach you how Potentiometers work. A potentiometer, or pot, is a three-terminal resistor with a rotating contact that forms an adjustable voltage divider. In our AI002 DIY...
