The ability of the
Optimus series to display the correct symbols, for each layer you're on, is intriguing
but the price and other problems are too big downsides for it to be a viable option.
But what if you could create a similar albeit a lot more restriced effect with a simpler method than lcd displays for each key.
Using per key programmable rgb lighting, (partly) translucent (
relegendable) keycaps and light filter gels, one could create a keyboard that can display the correct symbols for 3 different layers per key.
So I wondered if anyone on this forum ever tried to do this or if someone would be willing to try it?
What are your thoughts on this?
Edit: Found this
https://geekhack.org/index.php?topic=48584.0;nowap same idea but also no final conclusion only some additional problems were pointed out.
Edit2: Another similar disscussion
https://geekhack.org/index.php?topic=66953.0 with no conclusion.
Edit3: Did some research since the disscussion from the first link mentioned the potential problem of the filter gel blocking to much light.
After looking at a few wavelength-amplitude graphs of rgb leds and wavelength-transmission graphs of filter gels and I think you should at least be able to get ~50% of the original brightness of the led.
