Free Modular
This project is an attempt to make Eurorack modular synthesis affordable and accessible to everyone.
This repository contains open source software and hardware schematics for Eurorack modules which are designed to be assembled easily and cheaply without any technical knowledge. Every module should be able to be assembled for around $20 in about an hour of work, even with limited experience.
To get started, check out some of the links below.
Happy travels on your modular journey!

Modules
Clock
An 8-channel clock source with adjustable pulse width, phase shift, and swing
Envelope
A simple but powerful envelope generator/LFO with 4 modes
RNG
The Random Number Generator -- A module for creating semi-looping, randomized CV and gates. Inspired by the Turning Machine
Offset/Atten
A utility module to scale, shift, and invert signals
Mixer
A 5-channel active mixer for audio or CV. Can be daisy-chained together for larger mixes
Output
A stereo line out and headphone amp with VU meter
Drift
An organically moving, never repeating modulation source with 4 different algorithms
Boost
26db of overdriving, tone-controlled gain to boost outboard gear to synth levels or Eurorack audio into distortion
