Breaks out AV signals from a PSX connector.
PSX Breakout is an open-source printed circuit board by arithmaldor, from the arithmaldor/PSX-Breakout repository on GitHub. It is a 2-layer board of 100 × 44.9 mm with 15 parts on 20 nets, routed with 148 tracks and 33 vias.
Its parts include 5 connectors, 3 capacitors and 1 switch. It belongs with the interfaces and adapters boards of this library.

Breaks out all of the signals from the PSX AV out so you can easily access them.
Plug in and go.
Located on the back left of the board, this switch determines which signal goes to the HD15 port - CVBS or LUMA.
Refer to BOM.csv for all components. For the support leg, use any appropriately long brass/metal m3 standoff/pillar and screw a rubber foot to the bottom. Solder a 5mm spring clamp to the bottom of the board to adjust the height. For the phat PS3, standoffs may need to be screwed into each other (stacked) to reach the needed height.
The incredible Magic Trashman was kind enough to design 3D printable cases for both my Nintendo and PSX breakouts. They are under the same license as the PCB and are free to use, but if you order through thingiverse you can leave him a nice tip. Current designs fit the height of the original PS1 and the original SNES, but can be easily adjusted for height if you have some basic 3D design skills. They are held together with 2x 14mm M3 machine screws.

It measures 100 × 44.9 mm and has 2 copper layers, 1.6 mm thick.
15 parts. 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.
From the arithmaldor/PSX-Breakout repository on GitHub, at the commit this page was made from: the board is PSX Breakout.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask arithmaldor before reusing the design.
