What This App Does:

In short, QR-2-Brick takes this:

And turns it into this:

QR Code Source Image

It also presents a large grid pattern that you can download and print (PDF file) for building a QR Code mosaic that fits neatly on a 32×32 baseplate.

Then at LEGO shows visitors can use their smartphones to scan the QR Code mosaic and visit your website.

Notes:

Due to the way data is encoded in QR Codes, the URL can not be longer than 32 characters in order to fit on a 32×32 baseplate.

Try the following to make the URL shorter:

  • Remove the "www." portion (check the URL works without it first).
  • Remove the trailing slash '/'.
  • Use a URL shortening service such as TinyURL or Bitly.

After submitting the URL, you will get:

  • A grid pattern of the QR Code mosaic, where each square is a single black or white 1×1 brick/plate.
  • A downloadable PDF (*.pdf) file for printing (will fit on A4 or US letter paper)
  • A downloadable LDraw (*.ldr) file for loading into a CAD app (such as MLCad).

The QR Code will fit onto a standard 32×32 baseplate — technically it only covers 31×31 studs, one row and column is left uncovered (just add another 63 studs' worth of white plates).
