I guess you can consider this a mod. Someone took apart a PSP and installed a tiny motor, giving the portable system ghetto force feedback. It doesn’t look like the mod will be mass produced or anything and it’s more of a “look what I can do!” than anything else. Be that as it may, it’s good to see people “hacking” their hardware. If I had any technical skill to speak of, I’d be right there with them.
That reminds me of the time when I tried to mod an Xbox 1 and totally hosed the motherboard. Plug-in mods to the rescue!
