My next project has now started as until i find out what is causing the pi errors, I consider the basic qr reader stuff to actually work. Hopefully someone can read my blog post and test / help out by testing on the pi.
I have now combined zbar with turtle in python so that scanning in a qr code can control a turtle. Spent the latter part of yesterday evening 14/1 and this morning 15/1 creating printing then laminating small cards with various qr codes on for the new project.
Work will be put on github
I need to work out how to use arrays properly first.
