In what I have to say is an absolutely awesome looking effect, Everett Bradford, a mechanical engineering student at RPI (Rensselaer Polytechnic Institute in New York) went ahead and rigged up shoulder button lights on his PSP that are activated when you push them. Apparently he took the mod that had shoulder lights that stayed on all the time and changed it up a little.
He has put up a rather lengthy tutorial, complete with very large pictures, on how he managed to set up the lights. Again, due to my mechanical ineptitude, this is definitely not something that I would ever attempt… but if we have any readers out there with fairly solid soldering skills, feel free to try it out!
