PIC badge with LED matrix, IR, and open firmware
A slim open-hardware conference badge designed around a red 8x16 LED matrix, PIC18LF25K50, IR send/receive, USB bootloader, tactile controls, and attendee-written demos.

SourceIt brought serious badge hacking to Hackaday's first European conference and made the badge an explicit demoscene target instead of a passive souvenir.
Public sources document a 48 by 176 mm PCB, two Kingbrite 8x8 red LED modules forming an 8x16 display, PIC18LF25K50 USB microcontroller, SCT2024 constant-current sink driver, IR LED and TSOP6240 receiver, five tactile keys plus reset, two AAA batteries, USB Micro-B, ICSP, and optional accelerometer/hacking pads.
The badge used a Microchip USB bootloader and a small kernel for display refresh, key scanning, brightness, pause/sleep, and optical serial communication; public C framework and firmware files supported custom demos without owning a hardware programmer.
The intended event ritual was a demoparty: attendees could write code for the badge, push moving messages over an infrared terminal, play with Tetris and accelerometer demos, and show their hacks at the conference.
Lifecycle
The badge records preserve Tetris, moving messages, accelerometer readouts, and a planned demoscene contest as first-class badge activity.
SourceThe 2016 badge documented 9600 baud optical serial communication and IR terminal messaging between badges and from a universal remote.
SourceOperational history
The Serbia record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
The badge was open and hackable, but the entry path was more firmware-oriented than later MicroPython or app-store badge lines.
