Desk panic button to get rid of annoying coworkers

Workplace is a jumble of many different personalities and we all find some difficult people to deal with. If you are often annoyed by your coworkers who just walk over to your desk and rope you into long conversations that never end when you’re on deadline, Randy Sarafon’s (from Instruclables) desk panic button will help you get rid of them without hurting their feelings. Unlike other panic buttons, this one does not summon for help in emergency. The idea is when it is pressed it calls your own phone so that you can tell your coworker that you need to answer to this very important call and he may leave. The key components to build this desk panic button are an Arduino board, a GPRS shield and a sim card.

This instructable describes how to make a DIY GSM phone using Arduino Uno and GSM/GPRS shield. The project uses a TFT LCD with touch screen to provide an user interface required to operate the phone. This Arduino phone can receive & send message, dial & answer phone calls, and display real time clock.
