Mobile phone signal Booster for home

Mobile phones are a modern staple of most people’s lives today.  Social media and technological innovation have made them crucial to corporate and private life, so when you lose signal on your device, it could throw your entire day off.  WiFi isn’t always available in the workplace.  Sometimes architecture of a building or a campus thwarts signal coming from nearby. Sometimes an individual lives in a community primarily rural, and may only have several towers servicing several thousand.  It’s easy to fall through the cracks in a world of seven billion, and though cellular companies work round the clock to increase signal, sometimes there’s just no way to ensure all constituents in all areas will be able to have stellar service all the time.  The solution is to give clients the power to boost their signals personally.  Mobile phone booster technology is a great way to bring signal to rural or industrial areas where it just can’t be found, and there are many reasons it could come in handy.  But just what is it?

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 from USB. 5V boost circuit ensures right voltage to power the phone. Phone software runs a custom python soft called TYOS which gives easy way to make calls, display info like battery level, time, cell connection status, send SMS, etc. Continue reading

Redesigning mobile phone with rotary dial

Rotary dials are long gone since everything went digital. Now every device is equipped with keys or touch sensitive input interfaces. But if you feel a little nostalgic about old times you may find this project really interesting. This is a custom made mobile phone with rotary dial for input. We already know that building mobile phone isn’t that hard when you already have GSM modules around. All you need it so hook everything to microcontroller and LCD and you are up to go. jaromir instead of adding buttons or touch sensitive LCD went with simpler but yet interesting solution – a rotary dial. The phone is controlled with 8-pin DIP NXP LPC810 ARM Cortex-M0+ microcontroller. He had to squeeze everything to fit 6 IO pins. Shift register solves a lot here. No matter if it looks cool, making calls, entering PIN numbers can be real pain, but it works. As a phone it has huge enclosure due to large rotary dial size. You will definitely amaze your mates when taking calls. More pictures of it at Picasa. Continue reading
