Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The README says image-folder artwork is 12 pixels high and 1-bit, then converted into C headers for the firmware's bitmap display routines.
Badge context
Primary repository documentation for the POV Spinner purpose, LayerOne 2024 badge context, Kraken AVR programmer path, Microchip Studio and avr-gcc build notes, image conversion, and flashing workflow.
Firmware source for the ATTiny4313 LED mapping, hall-effect sensor interrupt, RPM timing, sleep behavior, button handling, and POV drawing routines.
Exact upstream `docs/spinner_photo.png` badge photo used for the local optimized WebP; the repository MIT license and README provenance provide the reusable image basis and attribution trail.
Official LayerOne post source for the May 25-26, 2024 Pasadena Hilton event context.
Official HHV page linking the 2024 electronic badge to the public LayerOne_2024 repository and describing electronic badge assembly in the village.
Public source repository for the badge README, AVR firmware, board and schematic files, image assets, documentation images, and MIT license.
Source trail
Firmware source proving the 12 LED outputs, hall-effect sensor timing, RPM calculations, sleep behavior, button-driven mode changes, and POV drawing implementation.
Primary technical source proving the POV Spinner was part of the LayerOne 2024 Conference badge and documenting LED POV behavior, Kraken programmer context, build paths, flashing, and image-header workflow.
Public badge source repository preserving the README, firmware, Eagle board and schematic files, documentation images, image assets, and MIT license.
Image and license trail for the selected repository photo: the README embeds this exact PNG, and the repository LICENSE is MIT with copyright (c) 2024 charliex.
Official village source linking the 2024 electronic badge to the LayerOne_2024 repository and documenting electronic badge assembly support in the HHV.
Official event source proving the May 25-26, 2024 Pasadena Hilton LayerOne conference context.
