Another successful implementation of Raspberry Pi cellular phone

There are many implementations of DIY cell phones based on Arduino and Raspberry Pi, so if you want something different than market can offer, you can start working on tour own version. Tyler lately introduced pretty slim version of RasPi phone called tyfone. Here raspberry Pi interfaces FONA – cellular module and 3.5” touch LCD display. Feature list extends with RTC and 5MP camera which enables taking HD photos. Raspberry Pi interfaces LCD module via SPI interface so, there are plenty of GPIO left for other periphery. FONA talks to Raspberry Pi via UART. Since Pi is a Linux driven board it easily houses other standard interfaces like WiFi. By default it comes with USB, and other RasPi interfaces. Typhone is powered with 1200mah LiPo battery which can be charged… Continue reading

Forget about Weak Signal with Mobile Phone Signal Booster

Have you ever had the situations in the office when you desperately needed to call your client and agree on a deal, but your mobile phone kept breaking saying that there was not connection? The Old Story of the Old World The story when people complain that their mobile phone is always out of coverage is not new and quite typical all over the world.

Mobile Phone Signal Boosters – Make your signal always accessible!

Signal reception on your mobile phone is weak? Do not worry! There exist certain appliances which help to amplify GSM or 3G signals in an easy way.  It’s possible to get rid of all problems with poor cellular signals and scarce coverage with the help of a special device – mobile phone signal booster. This equipment has the ability to improve weak signals of a mobile phone and fill in the lack of coverage. Mobile repeaters which intensify GSM signal or calls are called GSM boosters, those ones which stabilize 3G internet data transmission have the name of 3G boosters. Cellular repeaters improve the signal at any place where mobile phones may not work well:  at home, in the office or car, in areas such as parking lots, subways and… Continue reading

Easy to build DIY cell phone

If you are looking for a new phone with a modern looks as well as modest price tag a DIY cell phone is just the right thing for you. It features a 1.8-inch, 160×128 TFT LCD black and white display, and works with a standard SIM card any almost all GSM networks across the globe. It can make and receive phone calls and text messages, store names and phone numbers, and display the time. The hardware and the software are built on the Arduino GSM shield but with extended features.  The display is available in two version, one with the old black and white display that used to come with the old Nokia phones, while the other version is build using eight-character matrix of red led’s. It also has a… Continue reading
