There is a bit more to LED(s) than meets the eye. Yes, size is important, but, my first question is what forward voltage can be tolerated? The second is; if the LED brightness actually a current controlled loop what is the forward current set for? I have not sat down and done any detailed circuit analysis on the ergo infinity, but I didn't see any thing that was obviously a SMPS so I am assuming a pretty low forward voltage is required. The third is; can anyone who has built one in the past tell me if the LED brightness is adjustable? Regards, Deadline

The LED brightness is adjustable, there's built-in bindable keys for control. The board has appropriate resistors and a controller pre-soldered to the board. Based on the info found in this FAQ(http://people.eecs.ku.edu/~tlindsey/ErgoDox_FAQ.html), which references posts to this page from the first drop, the LED controller spec sheet is here: http://www.issi.com/WW/pdf/31FL3731C.pdf
Hopefully that gets you at least to some of your answers.
