I now have this working completely including the HT16K33 7-segment display.
Turned out that getting the display to work was a lot more work than simply changing the I2C address as it uses a totally different controller chip to the Sparkfun 7-segment display used in the original samplerbox project.
I had to write a new driver for the display, I have created a pull request into Hans' github repo as this might be useful for others (this 7-segment display is a lot cheaper than the Sparkfun one).
Also added a comment to the configuration.txt file to remind people to enable the UART in the BCM chip's config.txt file as it's not obvious.
I have to say, this is one of the coolest uses for a Raspberry Pi I've ever come across and I've been using them since they first came out and own most versions.
