Have you ever planned to record your phone calls? Then let’s do it! Engadget has the solution for all of us who still obtain an old modem: How-To Build a Telephone Recording Circuit from an Old Modem!

What you’ll need:

  • an old modem with an audio transformer
  • a soldering iron
  • a throughhole circuit board
  • a computer with mini jack audio in (and a Griffin iMic for older macs)
  • an extra telephone cable

I just have to find the old 28.8 modem somewhere in one of the boxes, or it is perhaps hidden at my mother’s place. Give me a month and I’ll be Mr. Big Brother!
