Well, you could be like me & spend a small portion of your evening tuning the LED OCD that you installed a few days ago, because those yellow LEDs somehow behave differently from all of the others (come on much earlier & stay on much longer).
Hardware installation: easy
Software installation: trivial
Hook up laptop to LED OCD: easypants
Create a new profile, assign it to all yellow lamps, tweak its brightness values a few times & send the settings to the LED OCD until the yellows were behaving: not at all difficult
(& then play a dozen unimpressive games)
(& then crack a beer)
