  • Maker Faire Rome 2013. The European Edition.October 14, 2013

    After some days from the Maker Faire European Edition, held in Rome, we want to share our experience there. New releases like Intel Galileo or Arduino TRE, a lot of very interesting projects from worldwide Makers, 3D Printers and companies involved in the Maker Movement.

    The First Day, 4th October, was the Educational Day. Many schools and high schools from Rome and surroundings came to the Maker Faire in order to be closer to new technologies. Something like Science Fiction they saw in films, became into reality in the Faire. Robots, LED panels, dresses with animated lights... and even helmets and SuperHero costumes were some of most visited booths there. We showed them the LittleBits Kit and Makey Makey, as well as a robot-speaker which danced the songs played by itself...

    The weekend was awesome, exhibitions, workshops, new releases, very long queues in the street to attend the event... The Maker Faire European Edition was to be a success... and it was. The results: 35,000 visitors in 3 days.

    We were prepared for that and we did all in our hands to show people some case studies to use Open Hardware. We showed our last releases of wireless communication like 3G shield or GPRS+GPS Shield for Arduino and Raspberry Pi, as well as Waspmote, our Wireless Sensor Platform. This event was perfect to bring closer this new technology to the makers. People was also very interested in the e-Health Platform, a shield that can change the philosophy of medical appliances. The possibility of body monitoring can be applied in small hospitals... or in Digital Art performances... You can do everything in your hand with the results you receive in your Arduino... and people were fascinated with that.

    In this weekend we were able to meet many people in person who we had met by email or through the Internet: Arduino Team, people from SeeedStudio, Snootlab, EXP, LinkSprite, Watterott... and Josef Prusa! I think he was one of the most photographed in the event due to the high attending of 3D Printer fans!!
    We were also able to know the new releases from Intel and Arduino: Intel Galileo and Arduino TRE.

    Intel Galileo is the new generation board developed in collaboration with Arduino, with the quality of Intel processors and the high community of Arduino, Intel Galileo is going to be a nice competitor for the Linux Embedded Devices.

    Arduino TRE will be released in Spring 2014. Developed in collaboration with BeagleBoard Team, Arduino TRE will be a strong competitor for Raspberry Pi, video/audio outputs, full compatible with Arduino shields, joining two big communities: Arduino and Linux.

    We are eager to wait for the next Maker Faire European Edition. Thanks and Congratulations to the Organization, Arduino Team and everyone involved in the event.

    If you weren't able to visit the event, take a look to the photos and don't miss the next one!

  • e-Health Sensor Platform V2.0 for Arduino and Raspberry Pi available!!August 28, 2013

    The e-Health Sensor Shield V2.0 allows Arduino and Raspberry Pi users to perform biometric and medical applications where body monitoring is needed by using 9 different sensors: pulse, oxygen in blood (SPO2), airflow (breathing), body temperature, electrocardiogram (ECG), glucometer, galvanic skin response (GSR - sweating), blood pressure (sphygmomanometer), patient position (accelerometer) and muscle/eletromyography sensor (EMG).

    This information can be used to monitor in real time the state of a patient or to get sensitive data in order to be subsequently analysed for medical diagnosis. Biometric information gathered can be wirelessly sent using any of the 6 connectivity options available: Wi-Fi, 3G, GPRS, Bluetooth, 802.15.4 and ZigBee depending on the application.

    If real time image diagnosis is needed a camera can be attached to the 3G module in order to send photos and videos of the patient to a medical diagnosis center.

    Data can be sent to the Cloud in order to perform permanent storage or visualized in real time by sending the data directly to a laptop or Smartphone. iPhone and Android applications have been designed in order to easily see the patient's information.

    What's new on 2.0 Version?

    In August 2013 Cooking Hacks launched the new version of the first biometric shield for Arduino and Raspberry Pi: the e-Health Sensor Platform V2.0. Thanks to the feedback given by the Community and several projects that have been created with it, we have improved the e-Health platform with new features such as:

    - New muscle sensor
    - New blood pressure sensor
    - Upgraded glucometer
    - New Connection possibilities

    You can find our e-Health Sensor Platform Complete Kit V2.0 to get a complete First Aid Kit for Makers or get the sensors separately.

  • R-Pi based Volvo S80 replacement nav systemJuly 12, 2013

    Reinis has been working on this Raspberry Pi based project for some time.

    It’s about replacing stock navigation system for Volvo S80 (which does not, and will not have maps for my home country). It had a nice motorized display and buttons on steering wheel for control. I really did want everything to be as close as stock as possible. It resulted in semi-usable navigation system, which replaces stock navigation unit in trunk- no wires running from trunk to dash- steering wheel buttons conveniently generated messages on CAN bus, which I connected to in trunk.

    Reinis has posted links on his website to an overview of the project, summary of the hardware design, and his actual prototype hardware and in-car testing.

  • Linux Embedded Devices Comparison: Yun, BeagleBoard, Rascal, Raspi, Cubieboard & pcDuinoJuly 1, 2013

    Awaiting for the new release, Arduino Yun, I think it's very interesting to know more about the new linux devices in the market. There are a lot of emerging ones and many of them agree in the same feature: to be Arduino-compatible.


    Arduino was launched in 2005 and it has become in a standard as a modular platform, so all new devices want to add this feature, allowing people to use each platform as easy as Arduino.

    Some can carry Ethernet, Wifi, HDMI, NAND flash... these features change in each board we are going to compare. But all of them have GPIOs, and even an expansion board to make the port easy.

    A quick review of each one


    Arduino Yun. Arduino Yún is the combination of a classic Arduino Leonardo (based on the Atmega32U4 processor) with a Wifi system-on-a-chip running Linino (a MIPS GNU/Linux based on OpenWRT). It’s based on the ATMega32u4 microcontroller and on the Atheros AR9331, a system on a chip running Linino, a customized version of OpenWRT, the most used Linux distribution for embedded devices. Like a Leonardo, it has 14 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator and a micro USB connector.

    BeagleBoard-xM. BeagleBoard-xM delivers extra ARM ® Cortex TM -A8 MHz now at 1 GHz and extra memory with 512MB of low-power DDR RAM, enabling hobbyists, innovators and engineers to go beyond their current imagination and be inspired by the BeagleBoard.org community. Designed with the community inputs in mind, this open hardware design improves upon the laptop-like performance and expandability, while keeping at hand-held power levels. Direct connectivity is supported by the on-board four-port hub with 10/100 Ethernet, while maintaining a tiny 3.25" × 3.25" footprint.



    BeagleBone A6. BeagleBone is a credit-card-sized Linux computer that connects to the Internet and runs software such as Android 4.0 and Ubuntu. With plenty of I/O and processing power for real-time analysis provided by an AM335x 720MHz ARM® processor, BeagleBone can be complemented with cape plug-in boards to augment functionality.


    Cubieboard. Cubieboard is a small (10x6cm), hacker friendly, extendable and very low-cost while powerful ARM board with Allwinner A10 SoC.


    pcDuino. pcDuino is a mini PC platform that runs PC like OS such as Ubuntu and Android ICS. It outputs screen to HDMI. Moreover, it has hardware headers interface compatible with Arduino.


    RascalMicro. The Rascal is a small computer that you can use to monitor and control the world remotely. The Rascal is powerful enough to handle real web traffic, but you don't have to be a professional electrical engineer to use one. The Rascal has its own web-based editor on board, it works with most Arduino shields, and you can program it in Python.


    Raspberry Pi. The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming.



    Which one should I choose?

    As I said in my previous post, comparing Arduino Yun and Raspberry Pi, it depends of your final purpose:

    miniPC: if you are looking for a portable PC with HDMI connection, there are 4 options in the table: BeagleBoard-xM, Cubieboard, pcDuino and Raspberry Pi, but Raspberry Pi allows to use a RCA output if your TV doesn't support HDMI connection. You can run a Linux distro, but you will need more RAM, depending of the use of your computer. In this case, you can choose between 1Gb (Cubieboard, pcDuino) or 512Mb (Raspberry Pi, BeagleBoard-xM). Regarding to the storage, Cubieboard has 4Gb NAND flash so you can take advantage of this feature instead of using an external storage. BeagleBoard-xM would be the most complete among them, with more I/O connectors for A/V: camera, S-Video, Audio (play, record)... Raspberry Pi and Rascal Micro would be the next but, if the price is one of the most valuable variables, Raspberry Pi would win.

    Arduino compatible: if you are looking for a direct Arduino compatible device, there are 5 options. The first one, Arduino Yun. It is the only one with embedded WiFi connection. It has a MIPS-based Wi-Fi SoC running Linino (similar to OpenWRT) so you can control the web server with this device and use it as a common Arduino (with the Digital/Analog I/Os). Rascal Micro and pcDuino have the same Arduino sockets so you will be able to plug any Arduino shield directly. There are some expansion shields or bridges for the other platforms, like the Raspberry Pi to Arduino Shields Connection Bridge. In this case, I'd choose Arduino Yun. Nice device which derives the complex control of WiFi connection through a Linux distro and combines it with the easy programming of the common GPIOs.

    Here you can find a comparison between the boards:
