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).
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…
