NodeConf EU 2019 NodeWatch

A NodeConf EU 2019 attendee smartwatch badge built around the NodeWatch/Bangle.js open-source JavaScript watch platform, with Espruino programming, nRF52832 BLE hardware, colour LCD, sensors, GPS/Glonass, app loading, and TensorFlow Lite gesture experiments.

Lifecycle

Add-ons & Upgrades

Operational history

Issues & Camp Impact

NodeConf EU 2019 NodeWatch note

TensorFlow Lite memory caveat · NearForm technical article · documented

NearForm's TensorFlow Lite writeup describes constrained RAM and model-loading tradeoffs for gesture recognition on NodeWatch/Bangle.js.

The machine-learning feature is documented as an experimental constrained-device implementation rather than a broad general-purpose on-watch AI platform.

NodeConf EU 2019 NodeWatch note

attendee-distribution evidence boundary · attendee report plus badge-site trail · documented with limits

An attendee report says the open-source smartwatch was handed to conference participants, while NodeWatch.dev and NearForm document the badge platform; this pass did not recover official registration or fulfillment terms proving exact distribution scope.

The record treats NodeWatch as the NodeConf EU 2019 attendee badge without claiming exact batch size, every-ticket entitlement, or post-event availability limits.

NodeConf EU 2019 NodeWatch note

image reuse boundary · local image policy and source review · left image-free

NodeWatch, NearForm, Flickr, Cloudinary, Hackster, and article media were not copied because this pass did not establish a complete reusable image license, attribution, source URL, and processing-provenance chain for a specific badge photo or official upstream raster.

The NodeConf EU 2019 page remains source-backed and image-free instead of publishing an unclear or synthetic watch image.

NodeConf EU 2019 NodeWatch note

missing rights-cleared image · local project policy · needs licensed original replacement

No NodeConf EU 2019 NodeWatch image is published because the current public source trail has not been paired with a reusable original badge or artifact photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.

The Ireland record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.

NodeConf EU 2019 NodeWatch note

repository-license boundary · repository metadata · documented

The BangleApps repository is MIT licensed, while related runtime/workshop/model repositories have mixed or unspecified repository-license metadata in the recovered source trail.

Software-resource links are preserved, but this record does not convert repository assets into local image or complete hardware-license claims.
