You don’t need that iPhone pocket fan, but it’s nice to know it’s available if I wanted to get one. Same goes for laser pointer, thermometer, ECG receiver, condenser mic, stethoscope, and all the other wonderfully fun stuff available at hmb-tec.de.
Using the mini jack for both i/o and phantom power, most of the accessories are small enough to carry around with you. If you’re curious about how this is accomplished and would like to implement it in your next project, check out Chapter 12 of the book iPhone Hacks for more detail. [via Crave]
