Hackaday Superconference
The November 4-6, 2022 return-to-Pasadena Hackaday Supercon 6 edition whose official badge was Voja Antonic's Voja4 front-panel 4-bit computer running on a PIC24FJ256GA704 with 272 LEDs, button programming, serial save/load, manuals, assembler, emulator, firmware, and SAO/IO expansion.
Pasadena, California · United States · 2022
The 2022 Hackaday Supercon 6 badge, also documented as Voja4, was a front-panel-style 4-bit computer badge designed by Voja Antonic and implemented on a PIC24FJ256GA704 with 272 LEDs, direct button programming, serial save/load, internal flash storage, SAO serial expansion, and a public assembler/emulator/tooling archive.
Lifecycle
The badge used a 16-bit PIC24FJ256GA704 to simulate a 4-bit educational processor with visible registers, flags, ALU, stack, memory state, and instruction execution.
The badge could save and load programs over serial to another badge or computer and store programs in internal flash slots for later recall.
The repository stores emulator, tutorial, examples, manuals, and firmware paths so the badge can be studied or programmed beyond the original event floor.
The public tools repository preserves Python assembler and disassembler scripts plus pseudo-op support for writing Voja4 programs outside direct binary entry.
Hackaday documented direct programming through tactile front-panel buttons and 272 LEDs that showed CPU state, data memory, opcodes, operands, and execution progress.
Operational history
The record treats manuals, firmware binaries, and repository artifacts as living owner-support evidence, not as proof that every recovered file represents a bug-free Pasadena production state.
The entry remains source-backed and image-free rather than copying public Hackaday media, Hackaday.io project media, or repository images without a complete image provenance record.
The catalogue cites the repository for source facts and tooling while withholding local image publication until a specific image license or permission basis is verified.
