It would be helpful for me (and others too, I imagine) to have a schematic for the IR-to-microphone circuit described in Hack 12.20.

The text explains what to do, but the risk of blowing out my iPod touch microphone circuity makes me hesitant.

Working with the description in words and deciphering row values on the Fig 12-135 breadboard photo is error prone. A nice schematic diagram would be better.

Thanks for your support, and clever projects.
