No time to hack? Don’t know which end of your soldering iron is hot? Well, check out Limor Fried and Phillip Torrone’s fabulous new video series, Citizen Engineer, a fun and thought-provoking show about hardware hacking.
In Volume One, Fried (also known as Ladyada) and Torrone demonstrate SIM card and pay phone hacking. For the former, Ladyada shows how to decode the cards and even decrypt the secret code that authenticates the call. (Not coincidentally, she offers a SIM reader kit in her online store.) The second part shows her popping open a Western Electric payphone to make it work with Skype, and playing around with the payment system. She even adapts the phone to allow her to red box it.
