Erica Synths DIY Kits Go Open Source

via Erica Synths

"We created Gerber files for PCB-made front panels and did slight changes in module design in order to get rid of custom and rare components, however some modules still require rare ICs which are available here.

Projects are available on Github and each project folder contains complete information and files to build a module: schematics, Gerber files for a front panel, Gerber files for PCBs, BOMs, component placement with values and designators and assembly manuals (please note that some manuals are designed for older module versions). By making these projects open source Erica Synths accepts third party use for personal, educational or commercial purposes.

Erica Synths will not provide any support for these projects so please refer to forums (Muffwiggler) for information on build nuances, troubleshooting, part availability or alternatives.

Open source projects are:

Bassline – all in one synth voice for acid basslines and drones

BBD delay/flanger – all analogue effects unit based on V3205 BBD IC Delay – tape and digital delay unit with tap tempo, tempo sync, reverse, hold and add functions

Dual VCA – Polivoks architecture inspired dual VCA, rare Russian differential op-amps are now replaced with AS3330

Envelope – recreation of Polivoks envelope generator with loop and end of attack functions

MIDI-CV – Polivoks functionality inspired dual MIDI-CV converter with glide function

Mixer – simple 3 chanel audio mixer

Modulator – Polivoks functionality inspired LFO, noise and S&H module

Output – Output module with headphone amplifier

Polivoks VCF – authentic recreation of the Polivoks VCF

Swamp – our take of Wogglebug module with lots of unique extras

VCO3 – Polivoks inspired VCO with nice extra – VCO Sync input

Thank you all for your ongoing support!

In collaboration with Riga Technical University we are now working on educational DIY kits for simple and affordable eurorack modules. The announcement is scheduled for Autumn 2020."
