SHA2017 Badge

A Badge.Team-supported Dutch camp badge with ESP32, e-paper, WiFi, Hatchery apps, WebUSB install paths, production lore, and a lasting role in European badge culture.

Lifecycle

Add-ons & Upgrades

SHA2017 Badge historical and partially live

app-store ecosystem

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

SHA2017 Badge historical

browser install workflow

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

SHA2017 Badge historical

firmware source lineage

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

SHA2017 Badge historical

hardware expansion

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

SHA2017 Badge historical

post-camp app hack

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

SHA2017 Badge historical

software add-on ecosystem

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

SHA2017 Badge historical

software platform layer

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

SHA2017 Badge major

production crunch · team retrospective · historical

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.

SHA2017 Badge moderate

manual assembly load · team retrospective · historical

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.

SHA2017 Badge note

documentation fragmentation · primary docs · historical

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.

SHA2017 Badge note

e-paper app constraints · app writeup · historical

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.

SHA2017 Badge note

image provenance upgrade · licensed source photo · licensed original replacement applied

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.

SHA2017 Badge note

web installer dependency · primary docs · historical

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.
