A PS/2 data tap over audio line in.
Why?
I thought it would be a fun thing to do.
How?
PS/2 keyboards transmit data at between 11 and 16 kHz, which is easily within range of every modern sound card. This board and software allow a user to tap a PS/2 line and read the transmitted keyboard data via the line in socket on the host.
The data could also be transmitted over a radio link, although loss in quality would hamper decoding of the data.

Questions
How big is the Dual channel ps2 tap PCB?
It measures 61.3 × 19.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dual channel ps2 tap use?
12 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.
Where can I download the Dual channel ps2 tap KiCad files?
From the dominicgs/PS2_tap repository on GitHub, at the commit this page was made from: the board is hardware/combined_tap/dual_channel_ps2_tap.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dual channel ps2 tap design in my own project?
Its repository states no licence, so its author keeps all rights: ask dominicgs before reusing the design.
