Remember that PlayStation Portable mod we featured a few months back? We're talking about Acidmods' Razor Nub. We've got a new video straight from zbblanton and anteroom123 of AcidMods showing off their progress with the said mod: a self center razor nub.

In case you're wondering what this mod is all about - either you missed earlier reports or just forgot, Razor Nub is basically aimed at adding a right analog stick to your trusty handheld. Today's video just shows some progress on the idea. zbblanton and anteroom123 have built an analog nub that self-centers like the real thing.

The tutorial for the said mod is still in the works, and we're pretty curious about how cool it would be to have two nubs on the PSP. Anyway, check out video to see mod in question.
