Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The next-version plan keeps the self-service update-station idea that was not fully reliable enough for PN26 field deployment.
Badge context
Official browser tool added on October 21, 2026 for designing a custom floppy-disk shutter for the badge's LEGO-compatible 2x4 socket: marker drawing, text in Osifont, Overpass, Orbitron, OCR-B, or Eat Fruits, SVG import, multi-colour inlay depth, and print-ready STL export. Its preview mesh is credited to a pn27-badge project file named epop55-cassette-stl-socket-4.stl.
Official PhreakNIC website for the November 6-7, 2026 event at the Clarion Inn & Suites, Murfreesboro. Besides preregistration and challenge coins, its news feed carries the September 30, 2026 PN27 Badge Sneak Peek post by tylercrumpton (new frame, cool wireless features, a ka-chunk-y slot for the disk, and a LEGO-compatible customizable shutter slider bit) with an official reveal video that is not reused here.
Official PN27 schedule entry, added October 9, 2026, for Tyler Crumpton's 11:30-11:50 talk on November 6: the badge is built on the same recycled hardware as PN26's, with conference customization, wireless communication, and battery-less operation.
Public source of the official site, including the September 30, 2026 badge-post commit, the October 9 schedule and speaker data, and the October 21 badge-customizer commit with its font and third-party notices.
Primary project-owner writeup that documents the PN26 ESL badge and explicitly says work was already underway on a cooler MK.II version for PhreakNIC 27, scheduled for November 6-7, 2026.
Source trail
Project-owner source for the public PN27 MK.II planning statement, future date, and expected follow-up direction from the PN26 ESL badge.
Primary official source that the PN27 badge has a LEGO-compatible 2x4 socket on the front where the floppy-disk shutter would go and that attendees may print their own shutter; it documents the case, not the electronics.
Official website for the November 6-7, 2026 event. Its September 30, 2026 PN27 Badge Sneak Peek post is the first organizer source for the floppy-disk frame, disk slot, wireless features, and LEGO-compatible shutter; it gives no electronics specification.
Primary official schedule abstract stating that the PN27 badge reuses PN26's recycled electronic shelf-label hardware and adds conference customization, wireless communication, and battery-less operation. It is a talk announcement, not a hardware release.
