MintyBoost made a smart little DIY USB charger for iDevices. Housed in an Altoids gum tin, the cool factor was automatically high.
It was cute, it worked great, until the folks from Cupertino changed the way it charged devices, thereby gimping third-party chargers.
But the MintyBoost team did not give up. What they discovered is that Apple puts unusual resistor values on USB data and power lines. The result is a near DRM for hardware. This is why third-party battery chargers don't always work the way they should.

If you'd like to order your own kit, it's available for $20 here
Mad props to the folks at Gizmodo.
