Well, the electronics bit will probably be more or less the same as the mayhew-labs ledring. My idea is to have a ~270 degree arc, aprox. 5mm wide cut out in the panel, and then insert a piece of cnc-cut plexi. that will serve as "lightpipe" and diffusor (if wanted) Most helpful. I've realised that 16 leds obviously makes it impossible to have 9,12 and 3 o'clock positions. So either I skip one led or makes the arch having one extra led on one of the ends.

The idea having a color of the cap as indication of where you are seems a bit.. odd. For personal use. Ok. But how to describe for others where, say 50% is? For led-rings the now discontinued http://mayhewlabs.com ledring, using a tlc5925 would be a great start. With some redesign you can get a boardlayout that is not even near the " bulkyness" of the original. I My self started to layout a board with a couple of encoders and surrounding led-rings. Guess what takes the most of the PCB-space? The leds of course. So the obvious soulution would be a slimmed led-ring PCB mounted to the "main board"
