Util lfo stripboard
Util lfo stripboard is an open source PCB design by nickajeglin: a 2-layer, 27.9 × 47 mm board with 21 components (18 distinct parts). It is built around the TL072. Filed under audio.
A collection of easy to solder DIY eurorack PCB's
VCO: ready to build, digikey bom provided, minor rework needed for V1.0, V2.0 ok.
Mult: Super easy first DIY project no surface mount parts. Ready to build, see interactive BOM for parts list, there's only like 3.
Mixer: Update 2019-04-28: prototypes built. I reversed the supply rails on the TL072 in the kicad schematic lol. That means I need to flip the power header, and change some silk around. Let me know if you want V1.0 and I'll email it to you
Built around
