The latest “Gadget Freak” from design news shows you how to make a remove telephone ringing indicator –
You leave your cubicle to get a cup of coffee. You get a few feet and hear a phone ring. Is it yours? You dash back and nope, not yours. You head back for the coffee and hear a phone ring again… Alan Vogel has a gadget that solves that aggravating problem. His Remote Telephone Indicator turns on a light above the cubicle when your phone is the one ringing. While employers may not look kindly on opening up phones and adding wires, the gadget is relatively simple. It senses when your phone is ringing and sends a signal to the light posted high above your cubicle. Even from a distance, you can see that your cubicleâ€™s phone is the one thatâ€™s ringing.
