How to Create Minecraft QR Codes #piday #raspberrypi @Raspberry_Pi

Pasted Image 12 22 14 3 51 PM

Adventures in Mindcraft author Martin O’Hanlon shared some tricks and some code tweaks to script a handy Minecraft QR generator:

I saw a tweet from @ImmersiveMind (aka Stephen Reid) linking to a new blog post about creating qr codes in Minecraft as a way of showing how to link the real world with the digital.

That afternoon I had 30 minutes to wait before I was picked up to be taken out for festive activities; could I code a Minecraft QR generator in time? It turns out I could!

I used the fantastic python module qrcode to create the QR, which has a useful function, get_matrix(), to allow you to get the QR as a 2 dimensional list of True and False’s.  I then used this matrix to create white and black wool – dead easy! ….

Read more about the route he took to create his qrcode generator as well as links to try it out for yourself.
