Life is interesting sometimes!
When I started this, after quite some research I discovered these LED driver boards that are controlled entirely by means of the I2C bus. These were designed and offered for purchase by another hobbyist and I bought 6 of them. 5 for the project and one as backup and for testing. I acquired these through his blog neuroelec.com and hoped that I would be able to do so again for the next project.
Unfortunately it seems that he has abandoned his blog, however, it being an open source and open hardware project, another user pulled over much of the information into another blog so as not to loose it and invited me to co-host the blog https://ledshield.wordpress.com.
I have mostly completed a redesign of the board with a few small improvements. We intend to get 50 of these manufactured as some people have voiced interest in this product and then I will be able to continue on my next lighting system project.
