Hand-charger for Nintendo DS

The most frustrating thing about handheld devices with integrated batteries is that when they run out of juice you can't just run out to the shop and get a couple of AAs -- you need to have a highly proprietary charger and a wall-socket. That's why this hand-cracked Nintendo DS charger is such a cool idea. No idea whether it's available outside of Japan yet. Link (via Waxy)
