Easy dial telephone

[Taufeeq's] Grandmother needed to be able to call her family members but due to ailing eyesight and memory this was a difficult task. He decided to help her with this by building a telephone that will auto-dial a number at the push of a button. [Taufeeq] built a case to hang on the wall which houses a hook for the receiver and two auto-dial buttons. The buttons are lighted and loosely based on the LED push buttons we covered in January. Housed in a separate box are a microcontroller and a dual tone multiple frequency IC used to dial the numbers. These are patched into a PCB from a standard telephone.

The result looks great and makes using the phone much easier with the simplified controls. We’ve included the demonstration video after the break.

Go there and see video...
