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.gitLicense

Questions
How big is the Psu PCB?
It measures 71.1 × 38.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Psu use?
15 parts, built around the NSD10-12D12. 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 Psu KiCad files?
From the shmoergh/hog repository on GitHub, at the commit this page was made from: the board is boards/psu/psu.kicad_pcb and its schematic boards/core/experimental/core.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Psu design in my own project?
Its repository states no licence, so its author keeps all rights: ask shmoergh before reusing the design.
