Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

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.

Today I learned you can generate a QR that connects to WiFi.

Android has this feature for a long time. Share the QR code even with iPhone users. And it will add them to the wifi

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.
