Citizen Engineer is an online video series about open source hardware, electronics, art and hacking. The first video debuted at "The Last HOPE" conference today in New York City. Volume 1is about 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...
Around the 12 minute mark it gets really exciting.

Want to build your own SIM card reader? The SIM card reader/writer is available at Adafruit Industries, it is for experimentation and investigation of SIM & Smart cards. Once the kit is built, accompanying software can be used to read and write from the card. Together they can be used to backup stored SIM card data, recover deleted SMS's and phone contacts, examine the last 10 phone numbers dialed, etc. (Despite being called a SIM reader, it can also write to SIM cards). Source, schematics and software included.





































Very good video! However, the audio is quite loud and quiet in some places, which makes it hard to hear ladyada and pt speak.

I thought that RS-232 ran at 5V as a norm.... On a quick check I'm seeing 3.3 - 12V.. That's one hell of spread...

I thought Red boxing was dead. Anyways, why not just by-pass the money to dial tone circuit?

1) Why is it SO INCREDIBLY HARD to log in here? Why can't I use my Make subscription ID thing?
2) I tried to subscribe to the citizen engineer RSS feed and got some physics/math forum. ???

LadyAda you rock - great video. Wow it's been a long time since I've seen the old radio shack tone dialer. I still remember buying one along with some crystals at the local radio shack and making up some lame reason for getting both at the same time.
