Badges are to hacker conferences what fashion is to the Hollywood red carpet:

The platform used for the Hackaday | Belgrade badge is the creation of Voja Antonic. It is a single PCB with 8×16 LED display, four directional buttons plus a fifth user button, and an IR receiver with IR LED for transmitting. The PIC18LF25K50 (which were donated by Microchip for the event) is running a bootloader that allows the badge to be programmed using a micro-USB cable. Programming options were many, using the abstracted C code to tinker without intimate knowledge of the underlying hardware, drilling down to the memory mapped electronics handled by Voja’s ‘kernel’, or going beyond to overwrite the bootloader using a programmer to run your own completely custom code. We saw every level of hacking this code, as well as a custom hardware hack. Much of this code has been posted to Hackaday.io
