Arduino hacked Ericsson T65 mobile phone GSM remote control. By Konstantinos Kokoras @ youtube.com:
Accepting incoming call from predifined caller and after 2 rings hungs up and turns on a device through a relay.
Also accepting incoming SMS’s from predifined caller and depending from text tuns on or off a device through a relay.
After each command execution it sends back a confirmation SMS.
Unfortunately Ericsson T65 has only PDU mode for SMS.

Timofte Andrei wrote this instructable detailing the build of his Arduino home automation system:
For this project I’ve used:
1. An Arduino clone
2. SIM900 GSM SHIELD
3. Relay module
4. 2×16 LCD Display
5. DS18B20 temperature sensor
6. Push button
7. Some Dupont wires
8. A led module (this is optional, if you have a chinese relay module with built in LEDs)
9. Some nuts and bolts to mount everything in place
10. A wooden chopping board or other kind of wooden board for propper display of the components

Track and Trace anything with the Arduino AnyTracer of only 25 x 25 mm! It is the smallest, complete GPS GSM tracker in the entire world.
A movie is not necessary here! The photos speak for itself. Together with the best Italian and Russian GPS specialists we managed to make the smallest complete GPS GSM tracker in the world. This tracker is only 25 x 25 mm! With the onboard STM32 microcontroller you can program it yourself with Arduino or online (!) with Mbed.org or in C using Keil or the opensource CooCox IDE. Almost anybody can do the programming with their own beloved platform.

New antenna 2J620P will provide you a high quality GSM and GPS signal at once, moreover with a very simple assembly.
Tracking of vehicles or goods is still more used what naturally results into a requirement for a suitable antenna. One of them can be the 2J620P. It offers a very simple and elegant solution, as in fact it is “2 in 1” – two antennas in one enclosure, each with a separate RG174 cable and SMA connector. Assembly is absolutely simple – by means of included double-sided foam pad. Also supplied is even a small towel filled by isopropanol for cleaning of a place of assembly as well as antenna itself.
2J620P has a 2.14 dBi gain for GSM and 26-28 dB for GPS. The GPS portion is equipped by an active amplifier, that´s why requires 2.7-5.5V/15-25 mA power supply. In many applications can be also advantageous a flat shape without any nibs.
Detailed description of the antenna can be found in the 2J620P datasheet.

New GSM/GPRS/GPS/GNSS modules Quectel offer also special functions, able to make your product exquisite.
Development in the field of communication modules is fast and there are still more segments for their applications. That´s why company Quectel always comes with novelties or at least with enhanced versions of existing modules. This is also the case of two novelties M95EB and UC15.
Module M95 is certainly familiar to you from several our articles like for example Even the Vodafone confirmed quality and reliability of Quectel M95 GSM module. M95 belongs to a TOP in the segment and recently we announced you an eCall support. Meanwhile, this version came to a mass production and we can easily differentiate it by the „EB“ suffix. New version M95EB also supports Dual SIM function (DSSS), what makes it extra reliable even for emergency systems and similar applications. A previous M95 as well as new M95EB are compatible and they will be on the market in parallel, that´s why company Quectel recommends to use the new version (EB) only for applications where you plan to use these new functions.The second novelty is the UC15 module (UMTS/ HSDPA), which is similar to UC15 in many respects, but it´s smaller (29x29x2.5mm) and it has only 66 pins. The main difference is that UC15 doesn´t support GPS/ GNSS and it´s also somewhat slower (upload). UC15 is cheaper than UC20 and in many applications it can represent a very interesting alternative for a very attractive price.
A comprehensive description and comparison of Quectel modules can be found in the Quectel brochure as well as in the datasheets in particular types.

UC20 module already provides besides a high speed UMTS/HSPA+ data transfer even the reception of data from GPS/ Glonass satellites.
When company Quectel launched on the market the UC20 3G module a few months ago, they also announced a forthcoming enhancement of functionality for reception of GPS/Glonass. We can unveil with pleasure, that reception of GPS/ Glonass signal via the UC20 module is already a reality and so this module has become one of the most versatile communication modules on the market. Combination of GSM/GPS/Glonass enables for example to design a device for monitoring of position of vehicles, goods, etc, by means of a single module.
At the same time, we also incorporated into our standard stock offer a miniPCIe version – UC20-E-MINIPCIE, increasing flexibility of usage of the module. All further information can be found in our recent article: Quectel 3G modules of UC20 series will ensure a fast transmission even on 900 MHz.

The highest communication speed UMTS/HSPA+ and an easy communication via USB make the new module ideal for M2M applications.
Fast data transmission is becoming an inseparable part of devices for automotive industry, measuring, tracking, security systems, wireless terminals (POS), mobile computers etc.
When we´re choosing a module for above mentioned segments, it´s surely worth if the module also offers somewhat so to say “extra”. In case of the UC20 module it´s true, because there´s probably no parameter, which would the UC20 not meet and when you look closer at the datasheet, you´ll also find another functions like for example 2x 15 bit AD converter and other. A big advantage of the UC20 is, that it supports a fast transmission even outside of the 3G networks thanks to a dual mode (+ Multi-band) for WCDMA but even GSM with a support of GPRS/EDGE Multi-slot Class 12. A considerable benefit are also the Windows USB drivers (Linux and Android drivers are in development).
UC20 can air itself even with a high sensitivity and a high integrity of transferred data even in adverse conditions. For a development support, there are also available reference examples – UC20-reference design as well as UC20-Compatibility design regarding HW compatibility of UC20 with the M10 module.
All package (12x pdf) of software user guides can be downloaded on this link (11MB). Detailed information will provide you the documents UC20-Specification, UC20-Presentation and UC20 Hardware design.
For many applications can be beneficial the UC20 module on a PCB in a form of the Mini PCIe card. Also available is the UC20_EVB development board.

jechavarria build a breakout board for the SIM900 GSM module. He writes:
Hi! I want to share with you my last design. It’s a breakout board for the SIM900 GSM module. Fits in a 50×50 mm board, and has an IO connector with many of the signals you need to control it. Also, as the board is designed to work with a battery, it also includes all the necessary components to charge and manage it. The internal power supply is 3.0V, so external controller must be work at this voltage. Here’re a couple of photos of the board

For a little over a year, I’ve been working on an open-source, DIY cellphone as part of my PhD research at the MIT Media Lab. The current version of the phone is based on the Arduino GSM shield and Arduino GSM library. It sports a deliberately low-resolution screen (8 characters, each a 5×7 matrix of LEDs), a laser-cut wooden enclosure, flexure (living hinge) buttons, and a ~1000-line Arduino program that powers the user interface. The phone can make and receive phone calls and text messages, includes a phone book and caller id, and keeps the time. Everything you’d expect from a 20-year old Nokia! (Except snake.) I’ve been using various iterations of the project as my primary cellphone for the past six months or so.
