Issue dossier
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
The record treats the badge as an optional workshop purchase and does not present it as the conference's admission credential.
Evidence
October 29, 2026 firmware release with a factory image, based on Meshtastic 2.8.0, adding the USB Canvas page, screenshots, flash-streamed sprites, and USB console fixes.
GPL-3.0 Meshtastic fork with the badge_jscon2026 target: mesh messaging, name tag, axolotl game, JSConf artwork, flashing and build instructions, pin and source map, and hardware test status.
July 6, 2026 release with the board and accessory BOMs as CSV files.
Electronic Cats' KiCad 10 project for the badge, revision v1.0, with schematic, PCB, custom footprints, a component table, and KiBot fabrication workflows. The README credits the hardware design to Lizeth Gallegos Martínez and states no licence.
Electronic Cats store listing at USD 50 for the board alone, with access to the workshop and open-source materials; it showed the badge out of stock on October 30, 2026.
Official agenda listing Controla hardware con JavaScript (W-01) on October 29, 11:00-13:30 in Taller B. Its prep note says the workshop needs the JSConf MX badge, sold on the day by the instructors for USD 50, plus a USB-C cable, a laptop, and a Web Serial browser, and links both Electronic Cats repositories.
Official site for the October 29-30, 2026 community-driven JavaScript conference at Jardín Americana, Guadalajara, with the speaker line-up, including Andrés Sabas of Electronic Cats and his W-01 workshop.
Electronic Cats' 41-slide workshop deck on LoRa and Meshtastic, Badge Studio for uploading images and controlling the badge over USB, and a Claude Code skill for writing badge-control web pages.
Source trail
Maker store listing for the price, the bundle of board and workshop access, and the out-of-stock state on October 30, 2026. It does not give a unit count.
Primary maker source for the hardware: ESP32-S3-WROOM-1-N8, VGdd79S915N0S1 915 MHz LoRa module with SMA connector, 428x142 colour display on a 10-pin FFC, four user buttons and a power switch, USB-C power with fuse and 3.3 V regulator, no battery or GPS, and a two-layer KiCad 10 PCB. It names Lizeth Gallegos Martínez as hardware designer and Andrés Sabas and Heikki Isa Perea Esparza as workshop presenters. No licence file or statement is present.
Primary maker source for the firmware behaviour: Meshtastic fork, US region and SHORT_FAST preset, name tag, 11-axolotl game with MAC-based starter and -80 dBm double-hello unlock rule, page list, flashing with esptool 5, LLCC68 radio, NV3007 display, and the hardware test status. Its screen images are labelled as computer-drawn mockups, not photos.
Primary official source for the October 29-30 dates and Jardín Americana venue, the W-01 workshop slot and instructor, the JSConf MX badge as a workshop requirement, its day-of sale by the instructors at USD 50, and the two linked Electronic Cats repositories. It does not say the badge is issued to every attendee.
