These QR codes are great. Discovered that the free scanner I have on the iPhone has a creator as well. The QR codes themselves look cool so thought it would be fun to create some and use them as graphics on the board. The QR codes can containn text or direct you to a website and an number of other things. I though it would be cool to have link to the construction photos of the board and also a write up on the board details.
Just scan it with you QR scanner
