TinyQR

Repository: github.com/Meandmybadself/tinyqr

Static client-only page: enter a URL, render a small QR code on a canvas sized for your Niimbot label, then print over Web Bluetooth using @mmote/niimbluelib (pinned in index.html).

Requirements

• HTTPS (e.g. GitHub Pages with “Enforce HTTPS”). Web Bluetooth is only available in a secure context.
• A Chromium-based browser with Web Bluetooth (Chrome, Edge, etc.). Safari does not support Web Bluetooth for this use case.

URL query parameters

• ?url= or ?u= — prefill the URL field and generate the QR. Encode the value, e.g.
  ?url=${encodeURIComponent('https://example.com/path')}

YouTube: Watch, Shorts, embed, music.youtube.com, and youtube-nocookie.com single-video URLs are rewritten to https://youtu.be/VIDEO_ID. Timestamp t / start is kept when present; other query params are dropped.

GitHub Pages and custom domain

1. Push this repo and enable Settings → Pages (source: branch or /docs as you prefer).
2. Add a CNAME file (already present) with your hostname: tinyqr.meandmybadself.com.
3. In your DNS provider, create a CNAME from tinyqr.meandmybadself.com to <your-user>.github.io.
4. After DNS propagates, enable Enforce HTTPS in the Pages settings.

See GitHub: custom domains for Pages.

Niimbot / label sizing

Pick the printer model (fallback if auto-detection fails) and set label length (mm) along the feed axis to match your roll. The canvas uses the library’s printheadPixels and printDirection for the other axis. Wrong dimensions will stretch or clip on the physical label.

Remembered settings: localStorage keys tinyqr.printerModel and tinyqr.labelMm store the model dropdown and label length between visits. Bluetooth auto-detect updates the model and saves it when it matches a known option.

Printed label: The URL is shown in small monospace text without the http:// or https:// prefix, with a line break after the hostname (path/query/hash on the next line). It is truncated to 25 characters total with an ellipsis when longer. The QR still encodes the full normalized URL. On wide canvases (width ≥ 140px and width ≥ 1.12× height, e.g. B1-style labels), the QR is left and the URL is drawn in the strip immediately to its right (not flush to the far edge) so the QR can grow with label height; narrower labels keep the URL in a band below the QR.
