Overview
Repauser is an open-source printed circuit board by doihaveto, from the doihaveto/repauser repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 40.3 × 39.8 mm with 16 parts on 13 nets, routed with 61 tracks and 0 vias.
Its parts include 8 resistors, 2 diodes, 1 IC, 1 connector and 1 switch. It belongs with the AVR (ATmega, ATtiny) boards of this library.
README
README.mdRepauser
USB-HID device based on attiny85.
The intended use of this device is to pause movies (press the space key) when the user rises from his chair, using a force-sensing resistor connected to the chair and the device.
Schematic
Included in this project:
- Source code
- Kicad project files
- Fabrication-ready board image files
Flashing instructions
I used USBASP to flash the code the attiny85, and AVRDUDE. The makefile included in this project uses AVRDUDE.
Default fuses (required for reflashing):
avrdude -p attiny85 -c usbasp -U lfuse:w:0x62:m -U hfuse:w:0xdf:m -U efuse:w:0xff:m
Reading fuses:
avrdude -p attiny85 -c usbasp -U lfuse:r:-:h -U hfuse:r:-:h -U efuse:r:-:h

Questions
How big is the Repauser PCB?
It measures 40.3 × 39.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Repauser use?
16 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 Repauser KiCad files?
From the doihaveto/repauser repository on GitHub, at the commit this page was made from: the board is kicad/repauser.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Repauser design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
