How-to build your Telephone Recording Circuit

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!
