I agree that it works well. A couple years ago my then 13 yr old son, Jonathan kb3rli, and I used it as a chance for him to learn some electronics because he wanted to key the rig with it. We used 2 op amps from a quad op amp chip to make an amplifier and a comparator. The ipod audio was amplified and compared to a voltage. Output of the comparator went to the gate of an npn transistor to key a rig. So he used his jail broken ipod (no iphone for a 13 year old!) to key the rig. We also used only one value of resistors so he could learn about series and parallel'ing them to get an equiv value. Maybe overkill to use an ipod as a key, but it was a fun project!
