Lockout left you with too much spare time? Why not take on this project from Engadget: How-To Build a Telephone Recording Circuit from an Old Modem. I've used Skype and Audio Hijack Pro to record telephone conversations before, but I've always been disappointed with the audio quality. I'd love to own the RemoteMix C+ I used to borrow from Ryerson, but it's just too expensive for how much I'd use it. Anyone with a soldering iron want to help me out with this?
