BalCCon Mini Cyberdeck 0o00
MC-0o00 CH32V003 mini cyberdeck badge
The BalCCon2k24 MC-0o00 badge scaled the cyberdeck idea down to a CH32V003 RISC-V board with LCD, six buttons, buzzer, GPIO/power interface, and the ability to connect to BCD-0o27.

SourceCH405 Labs
Project owner and documentation source for MC-0o00.
SourceWhy It Mattered
It shows BalCCon treating badges as a multi-year hardware ecosystem: the 2024 mini badge can interact with the 2023 cyberdeck rather than replacing it outright.
Hardware
CH405 Labs documents a WCH CH32V003F6P6 RISC-V microcontroller, ST7735 LCD, piezoelectric buzzer, six buttons, 2.7 V to 5.5 V power interface, and four GPIO lines.
Software & Apps
The documentation covers CH32V003 development context, demo behavior such as Pong-style interaction with BCD-0o27, and the broader BalCCon cyberdeck firmware path.
Lore
The MC-0o00 entry explicitly connects itself to the BCD-0o27, making the two badges part of one continuing BalCCon cyberdeck story.

BCD-0o27 companion mode
The Mini Cyberdeck documentation and firmware notes describe interaction with the earlier BCD-0o27 badge.

Hardware test firmware
CH405 Labs provides an MC-0o00 hardware-test binary that walks through display, button, and buzzer checks with user confirmation for pass/fail states.

CB Pong
CB Pong can run as a simple two-player Pong game or, when connected, as a game against a BCD-0o27 cyberdeck through the external interface.

Space Invaders

Melody Maker
The MC-0o00 Melody Maker firmware by Miaou lets users compose 48-note melodies, adjust tempo, move through notes, change note values and durations, and manage simple melodies on the badge.

Issues & Camp Impact
cross-generation dependency
note
MC-0o00's lore and demos depend partly on BCD-0o27 interaction, making it less complete when documented in isolation.
The page should cross-link both BalCCon cyberdeck badges as a multi-year hardware story.

manual self-test caveat
note
The MC-0o00 hardware-test firmware can check display, buttons, and buzzer behavior, but CH405 Labs notes that the simple cyberdeck cannot diagnose itself and needs user confirmation.
This keeps the production and repair story realistic: test firmware exists, but hardware validation still depends on human observation.

missing rights-cleared image
note
No BalCCon Mini Cyberdeck 0o00 image is published because the current public source trail has not been paired with a reusable original badge or artifact photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.
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.
