American engineer invents rotary dial-up mobile phone ring Internet magic device can only make phone calls.

[gearbest News] although today's smartphones have countless functions, as a portable mobile phone, its most essential function is to make calls. The term "telephone" has a history of more than 100 years. During this period, the telephone has experienced numerous iterations and appeared numerous forms of design, among which the rotary dialing phone is a kind of charming design. Recently, according to foreign media reports, Justin Haupt, an engineer at Brookhaven National Laboratory, has developed a rotary dial phone, which combines the new and the old concepts.

The core of the phone is based on customized ATmega2560v motherboards, Adafruit Fona 3G cellular devices and the rotary dial of Western Electric Trimline phones, all of which are stuffed into a 3D-printed shell. Its 2.1-inch electronic display displays missed calls and other important messages, while shortcut buttons allow you to quickly dial a contact. In addition, the display screen can also be used to check battery life and signal strength.

Haupt developed the phone to keep users as far away from the touchscreen as possible, but the question is, why do you have to have a rotary dial if you want to eliminate complexity? Nowadays, there are many mobile phones on the market that can't watch videos and play games, and the rotary dial seems to be making a mountain out of a molehill.
