LayerOne 2024 POV Spinner Badge
The LayerOne 2024 POV Spinner Badge was an electronic fidget-spinner conference badge that displayed words and patterns through a 12-LED persistence-of-vision strip while spinning.

Lifecycle
Add-ons & Upgrades
LayerOne 2024 POV Spinner Badge
source-backed
ATTiny4313 POV spinner core
The Makefile, project files, and flashing command target an ATTiny4313 AVR powering the spinning POV badge firmware.
LayerOne 2024 POV Spinner Badge
documented
1-bit image asset pipeline
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.
LayerOne 2024 POV Spinner Badge
source-backed
Hall-effect RPM timing
The firmware documents a hall-effect sensor interrupt, RPM calculation, and timing loop used to align the POV output with spinner rotation.
LayerOne 2024 POV Spinner Badge
documented
AVR flashing workflow
The README documents Microchip Studio or avr-gcc build paths, `L12024POV.hex`, avrdude flashing to `t4313`, and Kraken or Arduino ISP programmer options for attendees.

source-backed
12-LED POV display strip
`main.c` maps 12 LED bits to AVR ports and the README describes words and patterns displayed through persistence of vision while the fidget spinner turns.
Operational history
Issues & Camp Impact
The LayerOne 2024 visual uses the MIT-licensed `docs/spinner_photo.png` repository photo embedded in the public README for the POV Spinner badge.
The public badge page, image archive, and API can show a real repository badge photo with source URL, license, attribution, local source preservation, and optimized WebP delivery rather than synthetic or unclear imagery.
Changing badge firmware requires an AVR programmer path such as the Kraken programmer, Arduino ISP, or another compatible programmer plus avrdude or Microchip Studio workflow.
The catalogue presents the badge as hackable and source-backed while preserving the practical hardware access needed to modify surviving units.
The repository preserves firmware, board and schematic files, documentation images, and workflow notes, but this pass does not claim a complete BOM, production package, attendee count, or final manufacturing audit.
The record keeps hardware and firmware statements tied to the recovered public repository and avoids unsupported production-scale claims.
