How to: hook up a hard drive to your Nintendo DS

We'll forever be in awe of people like Alexei Karpenko, a modder who one day "decided to do a quick IDE to GBAMP hack". That's right -- as a casual aside, Alexei hooked up a hard drive to his Nintendo DS via a GameBoy cartridge originally designed to play short movies from a CompactFlash card. The hack is apparently possible due to similarities between the CF interface and that of standard IDE hard drives: Alexei simply soldered the correct pins onto a 40GB disk and connected it to a 11.1 volt battery and 5 volt DC-to-DC converter. As you can see, the unwieldy setup isn't much of a PSP rival (remember, that second "P" stands for portable), but the mere fact that it's at all possible will undoubtedly impress your inner geek.
