Build a Wi-Fi QR code in LEGO
A Wi-Fi QR code lets guests join your network by pointing a phone at it — no typing the password. brickcodes turns one into a build you can make from LEGO or 3D print.
Create your Wi-Fi codeWhat a Wi-Fi QR code does
It encodes your network name, password, and security type. Scanning it with a phone camera offers to connect automatically — handy for guest Wi-Fi at home, an Airbnb, a café, or an office reception.
Make one here
Choose the Wi-Fi mode, type your network name and password, and the code is generated on-device — nothing is ever uploaded. Then pick your colors and brick style, and brickcodes works out the exact plates on a single 32×32 baseplate. Start your Wi-Fi code.
Will it scan once it is built?
Yes. The symbol is re-encoded cleanly and centered with its quiet zone, so a finished build scans like any printed code — as long as the pieces and baseplate have enough contrast. brickcodes warns you if a color pair is too low-contrast to read reliably.
Build it or 3D print it
Export a printable PDF and a BrickLink wanted list to build it in real bricks, or download a 3D-printable model of the same code to print at home.
