This is another secret project that I can now write about. At the EuroPython I have been approached by the organizers of a Polish event Noc Informatyka (https://nocinformatyka.pl) and asked to prepare badges for the event. I agreed, and we produced 150 custom units.

Electrically it's identical to the PewPew Standalone, including the voltage regulator that is optional for Standalone, but included by default here. Mechanically, I used the same large LED matrix as in the EuroPython PewPews, but this time with a vertical arrangement of the device and with quiet silicone buttons, same as used in #µGame. The connector header has been moved to the bottom, to make room for the lanyard hanger, and there is a place for writing the participant's name. The battery holder for two AAA batteries is on the back, which is otherwise empty.

The units were produced and tested by @Makerfabs, and it all went very smooth.

I can't wait to see what the participants of the event will do with them!
