This DIY cell phone created at MIT manages to have something for just about every major contemporary subculture or hipster subset I can think of.
Nerds and tinkerers? Check. Wooden case for the steampunk set? Check. Huge antenna for the retro, skinny-jeans-wearing set? Check. Big buttons for the fat-thumbed and Luddite crowd? Check. Rugged design for outdoorsy types? Check.
The folks at the MIT Media Lab created this prototype with an SM5100B GSM Module that takes a standard SIM card and a custom circuit board. The screen will take you back to the last century at 160×128 pixels and the laser cut wood and veneer enclosure is just one of many possible exteriors, given the availability of 3D printing. While far from a smartphone, voice, texting, and other slightly old-school functionality is possible. All told, the parts cost between $100 and $150.

While books of phone schematics are common place in Shenzhen (and probably throughout China),an interesting website came up in my search results for something completely unrelated. Ever wonder how mobiles phones are designed to pack so much functionality into increasingly smaller packages? Have a look at cellphonediagram.com and you should find a lot of interesting material to learn from.

You used to have an Ericsson Cell Phone GA628 and you also loved it very much, however after few years of using, you’ve decided to change a brand new cell phone and you just threw it inside the drawer and never touch or look on it after that?
Well, instead of leaving it in the drawer, why don’t you reuse it and give it a nice little modification here?
This project wouldn’t cost you too much, as it is a cheap and power saving simple display for battery powered, thanks to the help of Ericsson GA628 display. Since it’s a readily available and the I2C interface allows the connection to a very small microcontroller as well! [via]

Embedded web applications are always exiting. Once device is connected to internet, you can have access and control from anywhere including cell phone. Weather station is a modular structure which consist of AVR based web server and sensor board. There are two LM335 temperature sensors and Freescale MPX4115A absolute pressure sensor attached. There is also a wind measurement sensor planned.
