DIY System — Combined Bill of Materials

Compiled from the eight mki x es.edu manuals in this directory. The Output Mixer manual is deliberately excluded. This is for a no-kit build: the manuals' kit-supplied items are included below where their specification is stated.

Combined totals

Boards, panels, and assembly items

Part Qty Notes
PCB 8 One each for VCO, VCA, VCF, EG, Mixer, Sequencer, S&H/Noise, and Wavefolder. The manuals do not provide manufacturing files.
Front panel 8 One per unit; dimensions and fabrication data are not specified in the manuals.
Eurorack 2×5 keyed male power header 8 The manuals identify this connector, but do not give a part number.
10-pin Eurorack ribbon power cable 8 One per unit; supplied by the kits, so exact cable length is unspecified.
DIP-8 IC socket 8 For TL072s.
DIP-14 IC socket 8 For TL074s and CD40106.
DIP-16 IC socket 1 For CD4017.

You will also need knobs for all shafted pots, plus the panel-mount nuts/washers supplied or specified by the chosen pots, jacks, switches, and LEDs. These mechanical details are not specified by the manuals.
