Given Daedalus/Ch_123 argued about backlit keyboards and cited a glowing model M as extreme case of blasphemy, i promised that sooner or later...
Today i received an M2 bought from Ascaii and I decided to recycle my old experiment on it (the qzerty layout was a partner in that decision )
Firstly I dismantled and cleaned the keyboard that was (obviously) a little dirty/yellowed
Then I used a set of recycled stickers, they are meant for black boards, but all in all the final effect on lit environment is not that bad.
Then I modded my USB rope light with an UV led, and although is impossible to get the idea in a foto (because the cellpone's image sensor is UV sensitive) the result is really nice in the dark environment: unlike the photos only the legends are visible to the naked eye.
BTW this is the final effect
This is how compare with a real backlight keyboard (105 blue leds @the maximum output v.s. a single UV led barely lit)
I must say that a 15€ board + 4$ spent on the stickers + 10 cent spent on the LED, are more than worth the result.
