Christoffer Jarnaker writes “Have an old wireless phone collecting dust in the cupboard? Have some spare time? Do you use Skype, MSN or similar to Voice chat?
Then have a look at this page, http://www.jarnaker.com/siemensskype, where I describe how to convert the wireless phone to give an line in and out to connect to your computer. The sound quality is perfect and I can walk about 300m from my house and still talk for free over Skype.

Cost $0.
Material used: one wireless phone, and one 3.5mm to 3.5mm plug (cut in half).
Tools used: screwdriver, knife, soldering iron.”
