Nokia Schematics Via Shenzhen

The silicon hacker behind the Chumby, [bunnie huang], was browsing through the Mobile Phone Megamarket in Shenzhen, China and stumbled upon an unusual repair book. It turns out the book had the schematics to hundreds of Nokia phones. It’s hard to tell if they are legitimate, but the amount of information makes them seem so. [bunnie] claims that the book is a learning experience because it shows how some sub-circuits are implemented. Also, it can be a good reference for sourcing parts. Since Nokia buys millions of each component, the supply of parts they use are stable. There are also editions for other brands, such as Motorola and Samsung.

Antique Phone Doorbell

[Bryan] sent in this cool doorbell he made out of an antique phone. After seeing similar phones for $150 to $399, he picked one up on ebay for $10. After some cleaning and polishing, it was looking fantastic, but fairly useless. At this point, he broke it open and started hacking to turn it into a wireless doorbell. He picked up a cheap wireless doorbell and proceeded to gut it. The transmitter side got an aesthetic overhaul, a big fancy button and nice LED in a 50’s style  were added. The receiver side got hacked up as well. It was incapable of pushing the required voltage to ring the phone’s bell, so he had to do some searching for a better circuit. Since his knowledge of electronics was limited, he was looking for something that could be plugged in and work without much modification. Eventually, he found the Silvercom AG1170-s5. At $7, he swiped it up quick. It may be a bit of overkill, but he’s using an arduino to trigger the whole thing when it receives the signal. You can download the Arduino sketch on the site.

RFID Controlled Phone Dialing

In an attempt to create an easier to use interface for the elderly, [Stephen] has put together this phone prototype which uses RFID tags to dial. It is common for our motor skills and eyesight to deteriorate as we get older. There are special phones out there, but generally the only changes they make are enlarged buttons and louder speakers. [Stephen] had the idea to make a system where an elderly person would hold up a picture of the person to the phone and it would dial. He picked up an RFID card reader and an Arduino. The code for the RFID reader was already available, and with minor modifications to prevent multiple swipes from hand tremors or slow movements, he was able to get it working pretty fast. The Arduino then sends the data to an ioBridge to make the call.He’s using Google voice to physically place the call, so you could probably adapt this to other services as well. You can see a video of it in action after the break.

Hacked Cell Phone Blood Analyzer

Lensfree Ultrawide-field Cell-monitoring Array platform based on Shadow or LUCAS for short is an amazing new hack by a researcher at UCLA. This quick little hack involving only some wire, a filter, and an LED might revolutionize blood testing. This hacked camera replaces a unit that is usually the size of a refrigerator and very expensive to run. This is a pretty amazing achievement and should serve as inspiration for hackers all everywhere.

FEMA Phone System Hacked


Over the weekend, a hacker broke into FEMA’s new PBX voicemail system, made over 400 overseas phone calls to Asia and the Middle East, and ran up a $12,000 bill. The low tech hack took advantage of a “hole” that was not covered when a contractor upgraded the voicemail system. FEMA is currently conducting its own internal investigation, but FEMA spokesman [Tom Olshanski] did not have any information about the contractor responsible or what specific hole was the cause of the breach. Ironically, Homeland Security, of which FEMA is a part, had issued a warning in 2003 about the very same vulnerability.

Engadget Goes In Depth With The IPhone 3G


Over at Engadget, they’ve taken some time to completely review the iPhone 3G. Take a few moments to stop reading about all the trouble activating them and read about the phone itself.

In short, they hit the following points:

  • The case feels thinner than it is.
  • The shape of the case makes it wobble on a hard surface.
  • Call quality is greatly improved.
  • Speeds are greatly increased.
  • Battery life is underwhelming.

They seem positive in their conclusion, we’ll have to wait and see how they feel after a little more time with it.

Neo FreeRunner Software Review


A first look from Ars Technica at the newly released Neo FreeRunner phone by OpenMoko reveals some interesting information. There are three different software stacks available to use; the Neo FreeRunner will ship with the GTK-based stack, referred to as om2007.2. It offers conventional smartphone applications, but most importantly, it includes “full root access to a Busybox shell with all of the standard scripting tools like sed and awk”. The ASU stack is what OpenMoko developers are currently working on; there are promises of a more user-friendly experience. The FSO stack, also currently in development, aims to resolve the issues brought up by having different software stacks for the same phone. Since none of the stacks are considered “fully functional”, OpenMoko may have a difficult time attracting a mainstream audience. Hackers may be hampered by the lack of available documentation, although there are resources for OpenMoko enthusiasts, if you just search hard enough. The final conclusion? While OpenMoko may be difficult to use, it compares favorably to competitors such as Google’s Android platform, which is less flexible.
