Notes: Original 812x1200 repository JPEG photo downloaded from the official Fri3dCamp/badge repository and preserved in Public/images/source. The README embeds this photo as a Fri3d Camp Badge 2018 prototype image; it shows real Ph0xx prototype boards on a workbench and is not generated content, placeholder art, or an approximate render. The public WebP delivery asset is metadata-stripped and otherwise keeps the upstream documentary photo without retouching. 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

Ph0xx is a strong European camp example of a badge designed for children, families, workshops, and hardware extension at the same time.

Hardware

Hackaday.io documents ESP32-WROOM, dual IS31FL3731 drivers for LED eyes, capacitive touch pads, buzzer, 18650 holder, IR LEDs, battery charger, and add-on connectors.

Software & Apps

The project documents MicroPython use, badge programming, and robot/expansion directions.

Lore

The name Ph0xx follows the fox-board shape; the docs present jewel and robot ideas as part of the intended play surface.

Lifecycle

Add-ons & Upgrades

environmental hardware add-on historical

Air Jewel

The Ph0xx project describes an Air jewel that could interface with a dust particle sensor and GPS, extending the badge into environmental sensing.

Compatibility: Fri3d 2018 Ph0xx

Source

factory/test tooling historical

Mass-production programming script

The production logs credit a Christophe-designed script that scanned for new USB ports and programmed multiple badges, supporting the 650-board test and assembly flow.

Compatibility: Fri3d 2018 Ph0xx production batch

Source

field experiment add-on historical

Air Jewel weather-balloon flight

The Ph0xx logs record a Fri3d Camp weather-balloon launch carrying a Ph0xx with the Air Jewel to measure air quality; the dust sensor stopped working at very low external temperature.

Compatibility: Fri3d 2018 Ph0xx plus Air Jewel

Source

hardware add-on ecosystem historical

Jewels

The Ph0xx project documents jewel add-ons as part of the intended hardware play surface.

Compatibility: Fri3d 2018 Ph0xx

Source

mechanical expansion historical

LEGO Technic mounting grid

The Ph0xx logs document 4.2 mm holes on an 8 mm grid so the badge could mount into LEGO Technic-compatible builds.

Compatibility: Fri3d 2018 Ph0xx

Source

robot hardware add-on historical

Bot Jewel

The Bot jewel boosted power for four large servos and was documented as the building block for turning Ph0xx into a bipedal robot.

Compatibility: Fri3d 2018 Ph0xx

Source

robot/mechanical expansion historical

Ph0xx robot path

The Ph0xx documentation points toward turning the badge into or mounting it on a robot using its hardware and mounting holes.

Compatibility: Fri3d 2018 Ph0xx

Source

web-to-Arduino animation tool historical

Easy Animation eye tool

The logs describe a web tool from an Area 3001 member that let attendees define LED-eye animations and generate Arduino code for Ph0xx.
