Making a mobile phone from wood sounds crazy and under normal circumstance that would be true, but this low tech device is proof that under the right conditions and with the right tools available, you would be able to produce a mobile phone from what you have lying around in your lab! Of course, you are going need most of the part from a mobile phone, such as the SM5100B GSM Module, screen and other essential such as the keys. However, basically, it could be damaged and now here it is with a wooden casing and it is able to work.
According to a post on the MIT High Low Tech pages by David Mellis, this is what the wooden mobile phone is all about;
The initial prototype combines a custom electronic circuit board with a laser-cut plywood and veneer enclosure. The phone accepts a standard SIM card and works with any GSM provider. Cellular connectivity is provided by the SM5100B GSM Module, available from SparkFun Electronics. The display is a colour 1.8?, 160×128 pixel, TFT screen on a breakout board from Adafruit Industries. Flexures in the veneer allow pressing of the buttons beneath. Currently, the software supports voice calls, although SMS and other functionality could be added with the same hardware. The prototype contains about $150 in parts.
