We recently remodelled our kitchen and dining area, and I wanted some art piece on the wall but couldn’t decide what. For months the wall was a little bare and we were having a lot of dinner guests. I realised our WiFi password was too complicated to keep reading out to family and friends so I built a QR code in Lego that automatically connects you to our guest WiFi. It looks good, and it’s Lego so it was a fun project with the kids. It took about 4 hours to build. The only problem was having enough 1x1 tiles to put on a 37x37 matrix.
The best part is that you can generate the QR code from your phone. It's a button in the wifi settings. Really easy way to share it from one phone to another.
