Some post ago we presented a PCB to mount the SIM900 module. The project is used in our GSM remote control and the Arduino GSM Shield. The dimensions aren’t big (1.75×1.95 inches) but in some cases they are too important for a projects, so…. ..we have developed a small PCB GSM module to build device like localizators (coming […]
The device is based on a GSM/GPRS module with included GPS. Its main function is to detect and communicate its own geographical position using, on the choice, the cellular phone reference system or the GPS. Its small dimensions are due to the use, for the first time, of a GSM/GPRS module integrating the GPS receiver. […]

I first started seeing the potential of technology during my first job in Boston. I worked in the tech scene and was surrounded by people who were full of ideas. And not just ideas, but skills to act…
We use an Arduino to program other ATmega without bootloader . This technique allows you to use all flash memory for code and make boards using new ATmega, cheaper than those with bootloader. The qualities that have made the success of Arduino are undoubtedly the open-source software, many libraries, a good hardware and a virtually infinite […]
This is a very low cost and simple Arduino GSM and GPRS shield. We use the module SIMCom SIM900. It’s the cheaper module now avalaible in the market. The module is not simple to mount by an hobbyst, so we use the Breakboard TDGGSM_900 that we presented in this post. You […]

Arduino Powered Micro Quadruped: From the previous projects on this page, you can probably see that I have a deep interest in robotic projects. In one of my previous Instructables, I built a quadruped robot using large heavy-duty servo motors, and this time I decided to try and mak…
The proposed solar optimizer circuit can be used for getting the maximum possible output in terms of current and voltage from a solar panel, in response to the varying sun […]
Arduino-powered quadrupedal robots are fairly common designs for hobbyists to build once they’ve gotten a little more comfortable with embedded systems. A problem with many of the pre-designed quad platforms is that they take a long time to assemble due to their large size. This is what inspired Technovation to create their own quadrupedal micro […]

Another day, another Apple leak (hey, iOS in the Car!) AND another Apple mock-up. Today’s comes from interface designer Todd Hamilton and it has our wrists aching for the real deal. Especially if that real deal looks and works… well, exactly like this mock. Appleholics have been on the edge of their standing desks expecting a line of wearables announced during March’s keynote and Todd’s iWatch concept looks like it came straight from Tim Cook’s deck.
