License: Creative Commons Attribution-Share Alike 4.0 International
Attribution: korrupt, Wikimedia Commons
Notes: Original 3264x2448 Wikimedia Commons field photo downloaded from File:Sha2017-badge.jpg, conservatively polygon-masked around the visible board outline, scaled to the site badge canvas, and preserved as a transparent source cutout before WebP delivery conversion. This is a close-up documentary badge photo, not a studio packshot; the original image crops the lower board edge and partial background remains where visible 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

SHA2017 helped establish Badge.Team as a durable European badge platform and volunteer network, bridging event identity, MicroPython-style apps, web installation, and post-camp reuse.

Hardware

Public docs describe ESP32-WROVER, a 296x128 e-paper display, six RGB LEDs, MPR121 touch controller, joystick, USB-C, LiPo charger, MicroSD, 6-pin SAO header, IRDA receive/transmit, audio output, and CC BY-SA 4.0 hardware design files.

Software & Apps

Badge.Team documentation covers drivers, WebUSB installer paths, Hatchery app installation, appfs, OTA updates, a menu/launcher, REST-style APIs, IRC/game/social apps, and a firmware/software repository trail.

Lore

The team credits list reads like a who's who of later Dutch badge work, including people who shaped MCH2022 and the wider Badge.Team ecosystem. Production retrospectives remember hundreds of PCB revisions, a PCBWay scramble after a first supplier failed, and tens of thousands of LEDs placed by hand.

Lifecycle

Add-ons & Upgrades

app-store ecosystem historical and partially live

Hatchery app store

SHA2017 used the Badge.Team Hatchery path for discoverable badge applications, and the current Hatchery index still exposes SHA2017-compatible project records.

Compatibility: SHA2017 badge firmware and Badge.Team Hatchery

Source

browser install workflow historical

WebUSB installer

The SHA2017 docs and Hack42 WebUSB installer preserve the browser-based badge installation path used by the Badge.Team platform.

Compatibility: SHA2017 badge over supported browser USB workflows

Source

firmware source lineage historical

ESP32 platform firmware

Badge.Team's ESP32 platform firmware repository anchors SHA2017 in the reusable firmware lineage later Badge.Team records build on.

Compatibility: SHA2017 and related Badge.Team ESP32 badges

Source

hardware expansion historical

SAO and IR expansion surfaces

The hardware docs record a 6-pin SAO connector and IR receive/transmit hardware, giving SHA2017 both badge-add-on and badge-to-badge interaction surfaces.

Compatibility: SHA2017 badge hardware

Source

post-camp app hack historical

Gameboy emulator on e-ink

Sprite_tm documented adapting a Gameboy emulator to the SHA2017 badge's e-paper display, preserving a concrete example of post-camp app hacking under unusual display constraints.

Compatibility: SHA2017 badge

Source

software add-on ecosystem historical

Badge.Team app and firmware ecosystem

SHA2017 sits in the early Badge.Team lineage where apps, contributed code, documentation, and post-event platform work became central.

Compatibility: SHA2017 badge

Source

software platform layer historical

appfs application filesystem

The event wiki links appfs as the way applications were stored and loaded on the badge, making installable apps part of the platform instead of just firmware demos.

Compatibility: SHA2017 firmware and MicroPython app storage

Operational history

Issues & Camp Impact

production crunch major

Niek Blankers' retrospective describes a production crunch with hundreds of PCB revisions, a first supplier that could not deliver, and a rapid PCBWay rescue to get boards made before camp.

SHA2017 is remembered as successful, but its production story still shows the logistics risk behind ambitious camp badges.

Confidence: team retrospective
Status: historical
Timeframe: pre-event production
Source note: Niek Blankers SHA2017 badge retrospective.

manual assembly load moderate

The retrospective says the boards used 30 SK6805 RGB LEDs each and that the team manually placed roughly 105,000 LEDs using laser-cut mylar solder-paste stencils.

The badge's visual polish came with substantial volunteer assembly effort that belongs in the compendium's production history.

Confidence: team retrospective
Status: historical
Timeframe: pre-event and camp preparation
Source note: Niek Blankers SHA2017 badge retrospective.

documentation fragmentation note

Key SHA2017 information is split across Badge.Team docs, the original SHA wiki, GitHub repositories, Hatchery, Hack42 WebUSB, talks, and retrospective posts.

The page should keep multiple source links instead of pretending there is one complete canonical source.

Confidence: primary docs
Status: historical
Timeframe: post-event archive
Source note: Badge.Team docs, SHA2017 wiki, GitHub, Hatchery, WebUSB, media.ccc.de, and retrospective sources.

e-paper app constraints note

The Gameboy emulator writeup highlights the challenge of adapting fast interactive graphics to an e-paper badge display.

This is useful lore for app-store records: the badge could run surprising software, but display technology shaped what was practical.

Confidence: app writeup
Status: historical
Timeframe: post-camp app hacking
Source note: SpritesMods e-ink Gameboy writeup.

image provenance upgrade note

The SHA2017 page now uses a licensed original Wikimedia Commons documentary photo cut out to a transparent derivative and served as WebP.

The badge facts and visual provenance are now aligned: the image record preserves source URL, CC BY-SA 4.0 license, attribution, and cutout-processing notes.

Confidence: licensed source photo
Status: licensed original replacement applied
Timeframe: current catalogue build
Source note: badge.gallery image provenance record for sha2017-wikimedia-korrupt-cc-by-sa-4.webp.

web installer dependency note

The WebUSB install path depended on browser USB support and a hosted installer, which made setup easier for supported environments but added platform and link-lifecycle dependencies.

The install workflow was accessible for many users, but the compendium records it as an ecosystem dependency rather than firmware alone.

Confidence: primary docs
Status: historical
Timeframe: badge install workflow
Source note: SHA2017 wiki and Hack42 WebUSB installer.
