OSHCamp 2023 Badge

WiFi room-sensor name badge

A WiFi badge for Open Source Hardware Camp 2023, designed as a name badge, solder-paste workshop board, USB-UART adapter, qwiic/STEMMA QT sensor host, and post-event Tasmota room sensor.

Notes
Original 3072x4080 repository photo downloaded from electrolama/oshcamp23-badge, auto-oriented, cropped to the visible front of the OSHCamp 2023 badge, conservatively masked around the PCB and laser-cut wooden badge frame, scaled to the site badge canvas, and preserved as a transparent source cutout before WebP delivery conversion. The upstream repository is licensed under the Solderpad Hardware License Version 2.0; this is a partial documentary build/workbench photo rather than a studio packshot, and the source frame crops the very top of the wooden decoration while retaining some close workshop context where it sits behind the badge. 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.

Why It Mattered

OSHCamp 2023 adds a UK open-hardware camp badge record where the badge is deliberately practical: participants could build it during the workshop, extend it with add-ons, and keep using it after camp as a sensor platform.

Hardware

The Electrolama writeup documents a WiFi radio board with ESP8285H16 QFN or ESP-12 module population options, USB-C power/programming, CH343 USB-UART, pushbuttons, a qwiic/STEMMA QT compatible I2C port, topper/prototyping contacts, and sensor-device use after the event.

Software & Apps

The default lifecycle is Tasmota: after the event, attendees can attach a qwiic/STEMMA QT sensor and turn the badge into a room sensor. The repository also preserves design files and example code paths for further hacking.

Lore

Electrolama framed the badge as celebrating OSHCamp's return as part of Wuthering Bytes 2023. The board mixed name-badge identity, workshop assembly, Paul Downey artwork, oomlout laser-cut add-ons, a 3D name-plate generator, and a topper board for prototyping.

Lifecycle

Add-ons & Upgrades

I2C expansion documented

STEMMA QT / Qwiic expansion

The qwiic/STEMMA QT compatible port gives the badge a plug-in sensor ecosystem for post-event use and experiments.

Compatibility: OSHCamp 2023 Badge

Source
hardware expansion documented

Badge topper prototyping area

The badge/topper arrangement exposed prototyping and expansion space, making the badge a workshop board rather than a closed souvenir.

name-badge accessory historical

3D name plate generator

The badge decoration workflow included a 3D name-plate generator so attendees could personalize the badge object without changing the electronics.

Laser-cut badge add-ons

The writeup credits oomlout and Paul Downey collaboration around laser-cut badge decorations that extended the base PCB into a more complete name-badge object.

post-event firmware lifecycle documented

Tasmota room-sensor firmware

Electrolama describes flashing Tasmota by default so the badge could continue as a room sensor after camp when paired with an external sensor.

Operational history

Issues & Camp Impact

default-firmware scope caveat note

Tasmota is documented as the default post-event firmware path, while deeper Arduino/example-code use should be treated as an extension path unless traced to a specific published build.

The catalogue avoids overstating app-store-like functionality for a badge whose public record is centered on Tasmota and open hardware files.

image provenance upgrade note

The OSHCamp visual now uses an optimized WebP derived from a transparent cutout derived from the Solderpad-licensed `images/oshcamp23_badge_04.jpg` photo in the Electrolama badge repository.

workshop kit dependency note

The OSHUG event page framed the badge session as a solder-paste and reflow workshop and told attendees to bring their own tools and accessories for programming and use.

The badge experience depended on workshop readiness instead of only passive distribution; that is useful context for anyone comparing camp-badge accessibility.
