The machine is already complete.
It has been aesthetically pretty well.
Lighting quality is not bad. No lights as much as a direct light but enough to read (looks better in reality).
Much light is lost by side to scroll horizontally without illuminate the page. Testing, I've seen hitting a plastic sticker as a broadcaster following a lighting and perfect. Pity that the adhesive prevents the reading with quality.
At the moment I leave him well. I can read perfectly well without the diffuser calm and get some stuff that makes diffuser without loss of quality for the next version of the device.
