I think it will have an nice glow under everything. Here's what ended up with, by accident (apologies in advance for the terrible quality).wcass wrote: ↑Not per-key lighting. The LEDs will be in the frame of the case and my hope is that the case will funnel the light to the barrel frame (under the key caps) and the case edge around the key caps. I will be using just a few bright LEDs so it is quite possible that the light will not be evenly distributed. The only way for me to know for sure is to test. Just for this test i will be using adhesive vinyl to make temporary reflectors to try to channel the light where i want it to go. Once/if i find something that I like, i can replace the vinyl with thin acrylic for a more professional look.
To illustrate what i am going for, consider this side view of the front edge of the keyboard. Grey lines are clear acrylic, blue lines represent a thin reflective covering. A red LED on the PCB shines up in a 120 arch. The top and front edge of the case (top and left side in this view) reflect the light so that the only place light can escape is under the key caps.
So that's an SMD RGB led mounted to the surface of the PCB, just below the acrylic. I do have a hole drilled through the acrylic just where the LED is, which I think helps the light enter the edge of the acrylic and spread it around. That wasn't my intention, I just wanted somewhere for the light to shine through in case I didn't go with clear acrylic. I get light all around the edges of the acrylic. I imagine the effect would be intensified if I had a white PCB instead.
Also, I kind of like the Model 'W' suggestion.
