Mutable Instruments' Eurorack Modules.

Forked from pichenettes' version and identical except:

  • Eagle brd and sch files converted to XML (making possible import into KiCad)
  • For some modules, KiCad versions have been added

I have updated this repo to reflect upstream changes, but I am no longer able to convert the Eagle files, so not all are available as XML.

  • Blades: Dual multimode filter.
  • Blinds: Quad VC-polarizer.
  • Braids: Macro-oscillator.
  • Branches: Dual Bernoulli gate.
  • Clouds: Texture synthesizer.
  • Ears: Contact microphone.
  • Edges: Quad chiptune digital oscillator.
  • Elements: Modal synthesizer.
  • Frames: Keyframer/mixer.
  • Grids: Topographic drum sequencer.
  • Kinks: Utility module - rectifier, analog logic, S&H, noise.
  • Links: Utility module - buffer, mixer.
  • Marbles: Random sampler.
  • Peaks: Dual trigger converter.
  • Plaits: Macro oscillator.
  • Rings: Resonator.
  • Ripples: Liquid 2-pole BP, 2-pole LP and 4-pole LP filter.
  • Shades: Triple attenuverter.
  • Shelves: EQ filter.
  • Stages: Segment generator.
  • Streams: Dual dynamics gate.
  • Tides: Tidal modulator.
  • Veils: Quad VCA.
  • Volts: +5V power module.
  • Warps: Meta-modulator.
  • Yarns: MIDI interface.

Questions

How big is the Volts v01 PCB?

It measures 21.6 × 25.4 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Volts v01 use?

4 parts, built around the OKI-78SR-5/1.5-W36-C. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Volts v01 KiCad files?

From the jonstapleton/mutable_eurorack repository on GitHub, at the commit this page was made from: the board is volts/hardware_design/pcb/KiCad/volts_v01.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Volts v01 design in my own project?

Its repository states no licence, so its author keeps all rights: ask jonstapleton before reusing the design.
