Hackaday Belgrade 2018 Badge
Retro-computing BASIC and CP/M badge
A battery-powered retro-computing badge with 55-key keyboard, 320x240 RGB TFT LCD, PIC32MX370F512H, external flash, speaker, BASIC interpreter, CP/M/Z80 emulation, and expansion-header hacking.

SourceWhy It Mattered
It is one of Europe's clearest examples of badge-as-computer: a conference badge that shipped as a programmable handheld, attracted demoscene entries, spawned modem and multiplayer-game hacks, and influenced the later 2018 Hackaday Superconference badge.
Hardware
The Hackaday.io project documents a PIC32MX370F512H with 512 KB program and 128 KB data memory, 55-key keyboard, 320x240 RGB TFT LCD, 2 MB external flash, audio circuit and speaker, AA battery power, and expansion header with serial and GPIO access.
Software & Apps
Jaromir Sukuba expanded an Adam Dunkels uBASIC base into Hackaday BASIC with badge-specific words for screen, color, LEDs, music, serial, keyboard, expansion IO, save/load slots, and CP/M/Z80-oriented workflows; firmware was published under MIT license.
Lore
Badge hacks included full-color demoscene work, a WiFi-to-serial BBS modem using a NodeMCU, serial multiplayer games, image-compression challenges, BASIC music, and post-event firmware flashing guidance.

Hackaday BASIC, CP/M, and Z80 emulation
The 2018 badge software turned the device into a BASIC and CP/M/Z80 playground for demoscene entries, games, music, serial experiments, keyboard apps, color-display work, and flash-storage hacks.

Expansion-header serial modem and radio chat
Post-event hacks used the expansion-header serial pins with a NodeMCU to create a WiFi/BBS modem and badge radio chat path.

Issues & Camp Impact
missing rights-cleared image
note
No documentary photo of the exact historical PCB has been cleared for public reuse.
Original Hackaday.io or event photos should be added only after license and attribution are cleared.

source-lineage caveat
note
The 2018 Belgrade badge evolved directly into the 2018 Hackaday Superconference badge, so searches often mix the European event artifact with a later US conference badge.
The compendium keeps the Belgrade event page separate while linking firmware lineage through the shared BASIC badge repository.
