When its time to select a new phone we start looking for different brands with different features. And it is truly hard to find what you need or what you want. We don’t argue with the fact that for everyday use it is best to select a manufactured phone which is small sized, tested and reliable. But for sake of curiosity why not to build another one to play with.
The following project is a cell phone prototype developed by check guy Adam. It is based on Atmega128 microcontroller featuring 128kB of flash and 4kB of SRAM. Barebones cellphone is is equipped with nice big LCD touch screen driven with 16-bit bus. GSM SIM100S module made it possible to make calls and send SMS. Phone is powered with 1000mAh LiPo battery. Probably more fun in it is a software. It seems that Adam spent some time on it to make it convenient and easy to use. It has nice user interface controlled with touch screen. Settings are accessible using icon based menu. You can store contacts so as you would do in a regular phone.
