LayerOne 2024 POV Spinner Badge
ATTiny4313 POV fidget-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.

- Original 800x335 repository PNG photo downloaded from the public charlie-x/LayerOne_2024 repository and preserved in Public/images/source as `layerone-2024-pov-spinner-photo-mit.png`. The README embeds this exact image as the L1 Pov Spinner photo and states the spinner was part of the LayerOne 2024 Conference badge. The repository LICENSE is MIT, copyright (c) 2024 charliex; this is a real repository badge photo, not generated content, a placeholder, or an approximate render. The published badge.gallery delivery file is an optimized WebP generated from the rights-cleared local derivative/source with metadata stripped, WebP quality 82, and a maximum side cap of 1600 pixels when the source is larger; upstream source URL, license, and attribution remain unchanged.

SourceLayerOne
Official LayerOne pages establish the Pasadena event context and public HHV link trail for the 2024 electronic badge.
SourceWhy It Mattered
It extends LayerOne's North American badge lineage before the 2025 GLiTCh BadgE with a compact soldered Hardware Hacking Village artifact, public AVR firmware, board files, and a rights-cleared repository photo of the real badge.
Hardware
The public repository documents an ATTiny4313 AVR core, 12 LED outputs, hall-effect sensor timing, button input, spinner PCB, programming pads, Eagle board/schematic files, and a Kraken or compatible AVR programmer path. The LayerOne Hardware Hacking Village page links the 2024 electronic badge to this repository and says electronic badges were assembled in the HHV.
Software & Apps
The README, Makefile, and `main.c` document Microchip Studio and avr-gcc build paths, the `L12024POV.hex` firmware artifact, avrdude flashing to `t4313`, 12xN 1-bit PNG image conversion into headers, hall-effect interrupt timing, RPM calculations, sleep behavior, button wake/mode changes, and draw routines for text and bitmap effects.
Lore
LayerOne's HHV page links the 2024 electronic badge to the public repository, while the README describes the POV Spinner as part of the LayerOne 2024 Conference badge and notes that attendees could obtain a Kraken AVR programmer for flashing experiments.
Lifecycle
Add-ons & Upgrades
badge controller
source-backed
ATTiny4313 POV spinner core
The Makefile, project files, and flashing command target an ATTiny4313 AVR powering the spinning POV badge firmware.
Source
firmware asset workflow
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.
Source
motion sensor timing
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.
Source
programming interface
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.

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.

note
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.

programming-access caveat
note
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.

source-depth caveat
note
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.
