I've added white LED light to to my existing UV box, so there is now a good back light to work with. And mounted the nano, power supply and touch screen to the enclosure (quite rough, but get things out of the way and more useable).

I need to find some time and head space to find a start on programming a application in Qt. Not something i'm looking forward to, as background has been command line or more recently MCU embedded.
