Overview
SHO is an open-source printed circuit board by eric-wood, from the eric-wood/SHO-PCB repository on GitHub. It is a 2-layer board of 52.1 × 25.9 mm with 20 parts on 11 nets, routed with 56 tracks and 0 vias.
It is built around the 1N4739A and BS170. Its parts include 3 connectors, 1 capacitor and 1 diode.
Main components

README.mdSHO Boost PCB
This is my first go at doing any sort of PCB work, so I picked a simple boost circuit: the Zvex SHO. To make it more usable for my use-case, I included the master volume control mod you've probably seen elsewhere.
Getting it made
For Oshpark you can upload the KiCad PCB file directly and it should Just Work. For other fabs grab the files in the gerber folder.

Questions
How big is the SHO PCB?
It measures 52.1 × 25.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SHO use?
20 parts, built around the 1N4739A and BS170. 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 SHO KiCad files?
From the eric-wood/SHO-PCB repository on GitHub, at the commit this page was made from: the board is SHO.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SHO design in my own project?
Its repository states no licence, so its author keeps all rights: ask eric-wood before reusing the design.
