Controlling appliances using text messages

A GSM remote control project designed by Vassilis Serasidis: Two years later I built another one remote control based on GSM module. I choose the GM-47 sony-ericsson module because it was very easy to handle it via AT commands. Moreover, the price was low enough for experiments. Finaly, I decided to release the source code […]

Emanuele has informed us of a new open source project known as OpenduinoGSM. This is a standalone wireless remote control board which communicates via GSM. With OpenduinoGSM you have the option of using the Arduino development environment, so anyone, even those who are unfamiliar electronics and circuits, can try to realize the automation they want […]

GSM GPS shield for Arduino

Boris Landoni draws our attention to the GSM GPS shield for Arduino designed by Open Electronics. “The shield is designed and based on the module GSM/GPRS SIM900 or the GSM/GPRS & GPS module SIM908, to make calls, voice and data connections via GPRS. This new version has several new hardware features, that allow maximum customization […]

DeepSec 2011: hacking GSM packets using scapy

In this talk from the DeepSec 2011 security conference Laurent ‘Kabel’ Weber, co-founder of the Chaos Computer Club in Berlin, details the enhanced scapy software tool to attack GSM via packet manipulation. This presentation introduces a scapy-addon allowing users to create GSM layer 3 packets using simple Python syntax. His hardware setup includes a USRP1 […]

Lessons learned with an external clock / USRP1 interface

In order to use even a high-priced SDR for GSM experimentation, an accurate clock source is indispensable. According to the GSM standard, a clock with “absolute accuracy better than 0.05 ppm for both RF frequency generation and clocking the timebase” is required. This means that with a standard USRP1 with frequency accuracy of 2.5 ppm, […]

GSM/GPRS & GPS modem with SIM900/SIM908 module

Boris suggests we look at this GSM/GPRS and GSM modem. A modem GSM & GPRS with SIM900 or SIM908 module. Allows you to create data connections on the GSM network through a standard USB interface. The cellular modems, particularly USB-stick ones, are now at very affordable prices, however they’re limited: they are explicitly designed for […]

TiDiGino, the Arduino-based GSM remote control

Boris writes about a new open source Arduino-based GSM remote control module, the TiDiGino: Using an ATmega 2560 and therefore the heart of Arduino, we have developed a universal remote control with GSM. This allows to control 2IN/2OUT, DTMF key, gate control and GSM thermostat activated remotely. The remote control very simple to use, thanks […]

Open source GSM/GPRS autonomous weather station

Andrianakis built an autonomous data logging system using a GSM/GPRS cell phone modem module to transmit data to a online server. It’s designed to read wind velocity for a future wind power station installation. A PIC16F877A communicates with a SIM900 GSM/GPRS module, and reads sensor values. By using a battery and a solar cell charger, […]

How to find your location using GSM data

Boris Landoni writes to call attention to his interesting article in Open Electronics describing how to find your location using GSM Cell ID data: The radio mobile network is made up of a number of adjacent radio cells, each of which is characterized by an identifier consisting of four data: a progressive number (Cell ID), […]

OsmocomBB: open source GSM software

Osmocom stands for Open Source MObile COMmunications. The crew developing the OsmocomBB (baseband) software project presented the above talk at the DeepSec conference last November in Vienna, Austria. As they describe their efforts: OsmocomBB is an Free Software / Open Source GSM Baseband software implementation. It intends to completely replace the need for a proprietary […]

DIY aerial drone spoofs cell towers, hacks wifi + Bluetooth

You’ve probably seen aerial surveillance drones. You also probably know that GSM towers can be spoofed to fool unsuspecting users into connecting and having their phone security compromised. Well at this year’s Blackhat conference recently held in Las Vegas, security researchers Mike Tassey and Richard Perkins demoed their Wi-Fi Aerial Surveillance Platform (WASP) capable of […]

GPRS Arduino shield with SIM900 module

McZ tipped us to the GPRS shield using the new SIM900 cellular data module in a followup to our position location with GSM cellular post. GSM/GPRS 850/900/1800/1900MHz … for voice, SMS, Data, and Fax in a small form factor and with low power consumption. It is controlled via AT commands (GSM 07.07 ,07.05 and SIMCOM enhanced […]

GSM SIM emulator using PIC Microcontroller

Here’s a project from EHobbyProjects which demonstrates their hack for emulating a GSM SIM card using a microcontroller, EEPROM and SIM card adapter. Their instructions include reading the IMSI and KI data from the original SIM, and then using their Configurator program and hex programming files in conjunction with a PIC16F877 and 24C64 EEPROM to […]
