  • e-Health Sensor Platform Helps You to Fulfill Your New Year's ResolutionsJanuary 11, 2016

    So 2016 is already here, and we are sure you have all made plenty of New Year's resolutions, trying to become a better person and improve ourselves. But let's face it, we make too many resolutions, and sometimes we set ourselves unrealistic goals, whether is learning a new language, quit smoking, losing some weight or exercising more.

    Here at Cooking Hacks, we thought we could give you a hand to succeed in one of the most popular resolutions: stay healthy. You can start by doing something simple like walking, running a few minutes or riding your bicycle, and constantly checking your vital signs thanks to our e-Health Sensor Platform for Arduino and Rapsberry Pi.

    e-Health Sensor Platform

    The e-Health Sensor Platform was designed as a prototyping shield for investigation and a low cost medical sensor platform, and is compatible with Arduino and Raspberry Pi. It allows you to perform biometric and medical applications where body monitoring is needed, making use of 10 different sensors that read relevant vital signs that could help you when you exercise.

    For example, you can check your pulse and oxygen in blood with the SPO2 sensor, or monitoring your breathing with the Airflow Sensor. You can control your body temperature, and the Electrocardiogram Sensor will allow you to know the electrical and muscular functions of the heart. The Galvanic Skin Response Sensor will let you measure the electrical conductivity of your skin (your sweating) and the electrical activity of muscles can be monitored with the Electromyography Sensor (EMG).

    In addition, you can wirelessly upload your biometric data to the cloud thanks to any of the 6 connectivity options available: WiFi, Bluetooth, Zigbee, 802.15.4, GPRS and 3G. Besides you can also visualize your data in real time with GLCD, KST, Serial Console and even with a SmartPhone Application.

    Check the e-Health Sensor Platform tutorial to know the full capabilities of this biometric shield.

  • Cooking Hacks will be at the Campus Party EcuadorAugust 25, 2015

    Cooking Hacks will be at the fifth edition of the Campus Party in Quito, Ecuador, from Sept 30 to Oct 4. Founded in 1997 as a gaming event, has since evolved into one of the largest events in the world on innovation and technology disclosure. This year's edition will have more than 260 hours of contents, over 30 workshops and 18 participative forums. Besides, CEPC5 will celebrate the 150th anniversary of Jules Verne's "From the Earth to the Moon" and will be inspired by his visionary perspective of the world.

    2015 is the innovation year on tech entrepreneurship and smart cities development, this is why two complete areas will be exclusively dedicated to explore the world of makers in START UPS & MAKERS and SMART CITIES.

    e-Health Sensor Platform

    e-health_product_1

    Luis Martín, Cooking Hacks R+D engineer will be talking in IoT revolution: IoT Accessible for Everyone about the fact that being able to connect any device to the internet is opening an endless world of possibilities, and for the first time thanks to low cost platforms and DIY makers can now compete on equal terms with large corporations.

    Particularly, one of the most restricted areas for makers and startups has been eHealth, due to the high cost of sensors in this field. Cooking Hacks will introduce the e-Health Sensor Platform, a low cost medical sensor platform designed for investigation, prototyping new devices and even as a diagnostic tool.

    This shield is designed for Arduino, Raspberry Pi and Intel Galileo and allows you to perform biometric and medical applications where body monitoring is needed with 10 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/electromyography sensor (EMG).

    In order to send all the biometric data to the cloud and store it or visualize it in real time, six different wireless connectivity options are available: Wi-Fi, 3G, GPRS, Bluetooth, 802.15.4 and ZigBee.

    A related case study will be presented with a live demo of this platform. This talk is scheduled for Oct 3 at 10 pm, more info here.

    Read about some real applications of the e-Health Sensor Platform:

    IoT Student Kit

    Luis will later give a workshop introducing the Iot Student Kit and Waspmote, Libelium solution for the Internet of Things. It is a wireless sensor platform specially designed for monitoring your environment and highly focused on autonomy and low consumption. It has a modular and horizontal approach that allows to collect data with more than 100 sensors available and several specific sensor boards that help to easily use these sensors (smart cities, gases, smart water, etc). You can connect all these sensors to any cloud platform using one of the 15 radio technologies available, from LoRa to WiFi, ZigBee or Bluetooth.

    The IoT Student Kit was designed in response to the increasing demand of developers for the IoT, and to empower Libelium's campaign to support technical education on wireless sensor networks and electronics. In addition to this campaign, Libelium will launch in the next months the IoT Spartan Challenge, an initiative to identify and give public recognition to the best developers.

    The kit includes a waspmote board and a sensor board, several sensors, a battery and ZigBee 802.15.4 modules. This workshop will make use of waspmote as the brain of a project that will be capable of monitoring our environment and wirelessly send all the information.

    IoT Student Kit

    The workshop will start with a presentation of this sensor platform and its role in the IoT, including a basic explanation on how to program a microcontroller. It will follow with some advanced functions like SD, accelerometer, interrupts or real time clock, and after that a description and several tests of temperature, luminosity and presence (PIR) sensors.

    The last step of the workshop will be to equip the project with wireless connectivity through an XBee module, so the information gathered from the sensors can be wirelessly sent for storage or visualization. This should provide the participants with some basic knowledge in order to be able to develop any IoT application they can imagine. The workshop will start on October 2nd at 8 pm, see the content here.

  • Weekly Recap - e-Health HacksJuly 31, 2015

    Here we have some projects and application related to Arduino and health. Obviously, most of what you can find in this area is not going to be a certified medical product, but it can be very helpful to research or to try out body monitoring.

    Measuring Heart Rate with a Piezo Vibration Sensor

    Heartbeat Sensor

    If you're thinking about developing a medical application this is one of the basics. Thomas was trying to make a water flow detector by measuring the vibration created by water in the pipe and ended up with a very simple yet effective pulse sensor.

    He wondered what would happen if he tapped the sensor to his finger, and surprisingly it was a pretty solid electrical signal of his heart rate.

    The sensor is a standard piezo. This kind of sensors respond to strain changes by generating an output voltage, so all he had to do was connect it to an analog pin of the Arduino board.

    After that he defined a threshold value to measure every heartbeat, and to monitor the heart rate he measured the time between two consecutive beats to make the calculation. After that the value is printed on the serial monitor.

    Check the Pulse and Oxygen in Blood Sensor from the e-Health Platform.

    Posture Sensor with Ultrasonic Module

    We all spend a lot of time sitting on a chair in front of a computer, so Max thought it would be a good idea to have some sort of device that would monitor our posture and warn us to avoid back pain.

    He considered using an accelerometer to measure the angle at a certain point or several pressure sensor in the chair, but he needed something relatively simple and cheap. So he finally decided to use a common ultrasonic sensor to measure the distance of the head to the back of the chair.

    Posture Sensor

    These are easy to use modules that are precise enough for this application. He used Arduino to program an ATtiny85 that reads the info from the sensor, and depending on the distance it beeps a small piezospeaker to warn you. The device is powered by 3 button cells and mounted on a piece of fabric to hide it on the chair.

    See the Patient Position Sensor for the e-Health Platform, that allows the user to monitor up to five different patient positions.

    Detailed description of the application here. Via Hackaday.

    Breathalyzer with MQ-3 sensor and Arduino

    Here's another useful application with some basic components, Daniel made a Breathalyzer that helps you to detect breath alcohol content. The idea is quite simple: read the alcohol content and make a visual indication with some LEDs.

    An Arduino mounted on a breadboard reads the data from a MQ-3 sensor. This sensor provides an analog resistive output, it needs a 10K potentiometer to calibrate and then it is connected to an analog pin in the Arduino.

    breathalyzer

    The board transforms this alcohol content data and depending on its value lights up the LEDs to make a bar graph indicating the alcohol concentration. Each LED is connected to a digital pin of the board and to ground through a resistor.

    Check this interesting application including the e-Health Platform: the e-Wheelchair.

    See the e-Health Sensor Platform Tutorial to find examples and applications of how to read and visualize up to ten different parameters.

  • Cooking Hacks at the Sónar 2015June 23, 2015

    Cooking Hacks was part of the recent Sónar Festival 2015 in Barcelona. Sónar is a three-day long electronic music festival that was founded in 1994, and has since evolved into a multi-themed event that includes all kind of artistic performances and multimedia exhibitions, enhancing creativity and technology.

    It is divided into Sónar by Day and Sónar by Night and, unlike most summer festivals, it does not take place in a field. Sónar by Day is located in the city centre (Fira Montjuïc), and apart from concerts and dj's it hosts showcases and expositions, and the Sónar+D, an international conference focused on creativity and technology, and the digital transformation of the cultural industries involved. It gathers not only artists but entrepreneurs, researchers and companies seeking to integrate music, technology and business.

    Watch below the intro video for the Sónar+D.

    Sónar by Night is located at Fira Gran Via de L'Hospitalet, far away from the city centre, with most part of the live shows and dj sets until late at night.

    Libelium attended Sónar with "Sensors for the Next Generation of Artists", a demo of some of our products and the projects explained below, and participated in the "European Commission: Open Digital Science and Art Workshop", which featured representatives from principal institutions involved in research, art, technology and culture.

    Zero Calories Can Dispenser

    So this is what we brought to the table. This project is a mind controlled fridge, so you can get a cool drink without physical interaction. A mindwave sensor measures brainwave signals and monitors the attention level of the user. This sensor uses the Bluetooth module PRO from CH to send the data to an Arduino Uno board.

    Zero Calories Can Dispenser 2

    Zero Calories Can Dispenser

    The Can Dispenser is controlled with the Arduino Uno, which collects the data from the Mindwave and displays your concentration levels in an LCD screen and an analogic gauge meter. So all this means that when you concentrate hard enough you get your drink: Inside the covering there is a thermoelectric cooling that uses the Peltier effect together with a fan to create a flow of fresh air.

    Partymeter

    This application could turn out to be really useful in a festival like this one. Build once again around an Arduino Uno, it is actually a portable medical station for measuring Galvanic Skin Response (sweating) and Pulse and Oxygen in Blood (SPO2):

    • Galvanic Skin Response Sensor (GSR - Sweating): Skin conductance, also known as Galvanic Skin Response (GSR) is a method of measuring the electrical conductance of the skin, which varies with its moisture level. Skin conductance is used as an indicator of psychological or physiological arousal.
    • Pulse and Oxygen in Blood Sensor (SPO2): Pulse oximetry is a noninvasive method of indicating the arterial saturation of functional hemoglobin. Oxygen saturation is defined as the measurement of the amount of Oxygen dissolved in blood, based on the detection of Hemoglobin and Deoxyhemoglobin.

    The Arduino Board reads the data from the sensors and sends it to the printer with our RS-232 Serial/Modbus Module. This module allows to connect console ports and special purpose equipment. So, in the end you will get a ticket from the printer with the measured levels and depending on them it automatically assigns you a party level: relaxed, normal, semi-altered, altered or super-altered.

    Partymeter 2

    The Partymeter makes use of the e-Health Sensor Shield, a board by Cooking Hacks that allows Arduino and Raspberry Pi users to perform biometric and medical applications where body monitoring is needed by using 9 different sensors.

    Radioactive Percussion

    Radioactive Percussion

    This project was developed by Cooking Hacks and it converts ambient radioactivity in a musical rhythm.

    It detects radiation with a Geiger-Müller tube, a type of particle detector that measures ionizing radiation. It is able to detect the emission of nuclear radiation, including alpha particles, beta particles and gamma rays.

    The Geiger Counter is integrated in the Radiation Sensor Board. This board is compatible with any tube that works in the range of 400V - 1000V and, in this case, is mounted on an Arduino Uno, but it is also compatible with Raspberry Pi and Intel Galileo.

    It has 5 LEDs and an LCD to indicate radiation levels and a piezo speaker that allows to hear the typical "chirp" in radioactivity counters.

    To quickly detect increases in radiation levels we use a Vaseline glass bead. This is a safe way to test your Geiger Counter: Vaseline glass contains a small amount of Uranium (less than 0.2%) so it is slightly radioactive but completely safe to handle.

    The Arduino and the Radiation Sensor Board are placed inside a covering, so put some Vaseline glass bead next to it and the music starts to play.

    We are very much looking forward to the next edition of this festival. We'll see you there!

  • A new update on e-Wheelchair project using e-Health Sensor PlatformMarch 25, 2015

    The e-Wheelchair project

    For almost a year now we have been following and supporting the e-Wheelchair project by Philip Case. You will certainly remember this amazing project in which Phil, aka “The Captain”, is developing a mind-controlled wheelchair using Neurosky products, Vuzix smart glasses, Mindwave Mobile and the Mindflex EEG and implementing Cooking Hacks e-Health Sensor Platform for body monitoring (e-Wheelchair project part1 – part2).

    What's new?

    The e-Wheelchair has a logo: Phil and his wife have designed a logo and a slogan. It's inspired by the glasses and the mind controlling the wheelchair. The slogan reads: “Power on your mind, move to freedom... ”. Hopefully it will help to bring the project to light and to stand out now that he's starting to promote it.

    Power on your mind, move to freedom...
    Power on your mind, move to freedom...

    Ups & Downs and Go Fund Me campaign

    Sarah Bennett, who is helping Phil and writing about him on her blog Tech and Toast, started a Go Fund Me page in order to collect everything necessary for the e-Wheelchair. Phil uses a Panasonic Toughbook because of its rugged design and shock protection but unfortunately somebody stole it while he was undergoing surgery. This Toughbook is essential for him since he only has use of one hand. Another drawback on this courageous journey was that last month Phil fell while getting into the chair. He hurt his back and has to have surgery again.

    But it's not all bad news, of course. Last thing we know is that the laptop has been funded by Vuzix, a technology firm that's supporting Phil, and the project keeps moving forward. He is using the Vuzix M100 smart glasses that he won in a competition. These glasses are controlled by voice and gesture and give you the functionality of a smartphone so it's very helpful to enhance the user experience. They also support native Android Apps so the e-Health Sensor Platform application is displayed on the glasses for real time view.

    More good news: Phil has now a Prusa i3 printer. A 3D printer is important because he can make himself the housings for the wheelchair and any customized parts he needs instead of having to buy them all.

    Another improvement to the wheelchair is the add-on kit. Now the project becomes portable and that way more affordable for people that don't want to buy a new wheelchair or don't have the funds.

    The e-Health Sensor Platform Expansion Box

    Complete eWheelchair and sensors

    As we said before, the e-Wheelchair includes the e-Health Sensor Shield to monitor vital signs such as Airflow, Galvanic Skin Response or ECG.

    Phil has designed and built an Expansion Box for the e-Health Platform. It's in a special built housing, covered in liquid rubber and waterproof. He included a display to visualize the data. The shield is powered by renewable energy through solar panels and a pair of dynamos.

    He also incorporated an additional part so that only the user or medical professionals can view it, since data protection is now a priority.

    The e-Health Sensor Platform has been extended in lengths so that patients can move from the e-Wheelchair to their bed and still be connected for monitoring Body Position, Airflow (Sleep Apnea), ECG, Body Temperature, SPO2 and Blood Pressure.

    The next stage Phil is looking into is to make the Blood Glucose system wireless. He is going to use a CGM device (Continuous Glucose Monitoring) with transmitter and receiver connected to the e-Health Platform in order to display the data on the Expansion Box, the M100 SmartGlasses and sent it to the cloud for either a doctor o carer to have access to. All of this focusing on protecting people's personal and confidential details.

    After these intense months Phil keeps working hard and carries on with his project. What started as a small plan is getting bigger and bigger. Now he's looking at exhibiting it as much as possible.

    We will be following up Phil's work and keep you posted about the e-Wheelchair progress.
