Flashing Instructions
There's no need for an extra flashing device, it has a bootloader so it can be programmed directly via usb. The only thing needed is the "dfu-programmer" software, more info: https://dfu-programmer.github.io/.
lsusbFind the Atmega device in the list. If it's already been flashed, it will show up as "dc24:1337". To get it into a mode to reflash it, follow the directions in the "Reflashing" section.
sudo chown 666 /dev/bus/usb/02/020
dfu-programmer atmega32u2 erase --force
dfu-programmer atmega32u2 flash --suppress-bootloader-mem blinkybadge-test.hexReflashing
Run the "reset_badge.py" script to temporarily enable flashing.

Questions
How big is the Blinkybadge PCB?
It measures 76.2 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Blinkybadge use?
51 parts, built around the ATMEGA32U2-AU, MCP73831 and WS2812B. 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 Blinkybadge KiCad files?
From the cryptovillage/badge2016 repository on GitHub, at the commit this page was made from: the board is hardware/blinkybadge.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Blinkybadge design in my own project?
Its repository states no licence, so its author keeps all rights: ask cryptovillage before reusing the design.
