Badges
Battery-less ZBD shelf-label badge with per-attendee firmware images
PhreakNIC 26's official electronic badge reused dead-battery ZBD 55c-RB electronic shelf labels as 3D-printed pager-styled badges with static 240x96 one-bit displays, QR-code-backed attendee customization, and on-site reflashing.
Pre-event recycled shelf-label badge in a floppy-disk frame with a LEGO-compatible shutter
A pre-event record for the PhreakNIC 27 badge ahead of the November 6-7, 2026 conference in Murfreesboro, Tennessee. Tyler Crumpton's PN26 writeup announced a cooler MK.II electronic shelf-label badge, and the official PhreakNIC site now confirms it: a September 30, 2026 sneak peek describes a new frame, wireless features, a disk slot, and a LEGO-compatible customizable shutter slider; an October 9 schedule entry for his talk Shelf Label 2: Electric Badge-a-loo says the badge is built on the same recycled hardware as PN26's with conference customization, wireless communication, and battery-less operation; and an October 21 Badge Customizer lets attendees design and download STLs for their own floppy-disk shutter. Final electronics, firmware, and handout are not yet documented.
