Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The public tools repository preserves Python assembler and disassembler scripts plus pseudo-op support for writing Voja4 programs outside direct binary entry.
Badge context
Hackaday reveal source for the Voja4 front-panel concept, PIC24FJ256GA704 controller, simulated 4-bit CPU, tactile programming buttons, LED memory/register display, SAO serial behavior, save/load, and flash slots.
Repository directory preserving the user manual, instruction set, special-function-register, direct-mode, and hardware manuals.
Repository directory preserving the public firmware binary and firmware README path used as source evidence without treating repository images as rights-cleared media.
Hackaday.io starter guide for direct binary programming, PGM/DIR/SS modes, examples, assembler, emulator, and technical deep-dive links.
Raw README source for Voja4 naming, badge reveal links, Hackaday.io guide links, assembler, disassembler, emulator, examples, manuals, software, and tutorial structure.
Public Hack-a-Day repository preserving tutorial material, assembler/disassembler, emulator, examples, firmware, manuals, software, and the Voja4 badge archive.
Assembler/disassembler source for Python tooling, Mike Szczys documentation credit, serial save/load workflow, and pseudo-op support.
Voja Antonic's technical page for the 4-bit simulated CPU, 272 LEDs, instruction set, execution speed, memory model, stack, bootloader, IO port, serial save/load, two-AA power, and SAO serial I/O.
Source trail
Primary source repository for tutorial, assembler, disassembler, emulator, examples, firmware, manuals, software, and the repository image candidate that remains unpublished locally due incomplete image rights.
Raw README source for Voja4 naming, official links, tutorial sections, software tools, manuals, and repository layout.
Source for Python assembler/disassembler behavior, pseudo-ops, serial save/load workflow, and Mike Szczys tooling/documentation credit.
Documentation source for user manual, instruction set, special-function-register, direct-mode, and hardware manual artifacts.
Primary reveal source for Pasadena return context, Voja4 concept, PIC24FJ256GA704, simulated 4-bit CPU, front-panel programming, LED memory/register view, SAO serial behavior, and save/load slots.
Official guide source for direct on-badge programming lessons, assembler/emulator flow, and links into the repository and technical project.
Primary technical source for 272 LEDs, 31 instructions, speed control, program/data memory, stack, bootloader, 4-bit IO, two-AA power, SAO serial I/O, and owner support notes.
