Hog

Fully analog two-voice monophonic synth for live performances.

hog-4

Details and user guide: shmoergh.com

Latest revision: rev #3.

Build

The HOG is a very fun but equally advanced electronics project. It's fully open source and we've put together a build guide for the brave ones who decide to build one. Let us know if you have questions and definitely share some pics of your builds (follow Shmøergh on Instagram).

BOMs

The HOG consists of 5 separate boards which you can find in the boards folder. Each board has it's own gerber files for JLCPCB PCB and Mouser BOMs in the board's production folders. The Core and Filter boards have SMD components too for which you can find JLCPCB assembly files (BOM and position) in the production/jlcpcb folder.

Cloning

The MIDI2CV module uses pico-lib submodule. Make sure you clone the repo like with its submodules:

git clone --recurse-submodules git@github.com:shmoergh/hog.git
