Citizen Engineer is an online video series about open source hardware, electronics, art and hacking by Limor (Ladyada) Fried of Adafruit Industries & Phillip (pt) Torrone of MAKE magazine. The first video debuts at "The Last HOPE" conference in New York City.

Volume 01 - Phones: SIM card & payphone hacking
Learn how a SIM card works (the small card inside GSM cell phones) make a SIM card reader, view deleted messages, phone book entries and clone/crack a SIM card.

Modify a "retired" payphone so it can be used as a home telephone and for VoIP (Skype). Then learn how to modify the hacked payphone so it accepts quarters - and lastly, use a Redbox to make "free phone" calls from the modified coin-accepting payphone.
Length: 30 minutes

    The video ends rather abruptly at 23:40 for me.

    this now fixed (for folks who do video, vimeo seems to like 44khz sound vs 48 khz sound, otherwise the video might get cut short, weird - but confirmed)...

    That's really cool! I'm a software engineer, but these vids make me want to get into hardware.

    This is very, very well shot! Good angles that make understanding what you need to get a LOT easier than many tech videos out there. =D Very well done! I'm impressed!

  • Great!
    I think that Opensource is based on Knowledge Sharing and you have represented very well my idea!

    Great Job!

    Thanks a lot.

    Very nice video, but I need to know something. At 25:00 does someone say "shit"? Or am I just hearing voices?

    Where was I 8 months ago when this was posted, under a rock!?

    This is so much cooler than what they put in those Hollywood Action Movies. Big ups for your contributions to the hacking community at large.
