  • Autonomous Biometric Sensor Device with Remote Monitoring in Real Time with e-Health sensor platformAugust 2, 2016

    Autonomous Biometric Sensor Device with Remote Monitoring in Real Time with e-Health sensor platform

    This is a project made for all mountain lovers. As you know, mountain sports are more than a walk. You need some experience and preparation to enjoy them safely. In this sense, it is strongly recommended to be located and monitored all the time.

    The aim of this project carried out by Cooking Hacks team is to develop a device capable to measure different biometric parameters, using some sensors compatible with our e-Health sensor board and send these data in real time to a receiver by means of a LoRa and 3G/GPRS wireless connection. It is ready to use during exercise or with a person who has suffered an accident in a remote and hard-to-reach place. The scope of this project is the sports medicine.

    The hardware base is the Arduino MEGA 2560 microcontroller board and the e-Health Sensor Shield V2.0. The rest of hardware components are:

    Finally, the project was tested to know its consumption and its coverage. The battery duration with LoRa connection is around 17.5 hours with a 250 mAh average consumption. With 3G and GPS connection the battery duration is around 6.5 hours with a 667 mAh average consumption. After the coverage test, we observed that this device could send data up to 21 km from the transmitter and the receiver.

  • Arduino LED Lamp Controlled with RFID TagsApril 15, 2015

    RGB LED Lamp

    This is another project made by the Cooking Hacks Team. To develop this project we reused an old desk lamp. They are useful and everybody needs one but, to be honest, they can be a little boring.

    So we thought of somehow making it a bit more entertaining and we added several colors and a contactless way of choosing between them.

    It is a RGB LED Lamp controlled with RFID tags. Making use of several cards (or tags) you can choose the color of the lamp: red, blue, green, white or random.

    This time, the mind behind the project is Marcos, from the R&D department in Cooking Hacks.

    But, what is RFID? RFID stands for Radio Frequency Identification. This term includes technologies that use electromagnetic fields to automatically identify and track tags attached to objects.

    An RFID system consists of a reader (transceiver) and a tag (transponder). The tag usually contains a chip and an antenna: the info to identify a person or an object is stored in the chip and the antenna allows the chip to transfer the identification data to a reader.

    The reader creates an electromagnetic field through its antenna, and when the tag is placed close enough to receive the signal it responds by sending back the info stored in its chip. Then the reader is able to process the information sent by the tag and transmit it to a computer program.

    Recycling the old lamp

    First thing we did was to look at what we had in our hands. We opened the lamp to see if we could use anything but, since we are building everything around an Arduino Uno and LED strips, there wasn't really much we could take advantage of.

    RGB LED Strip

    We ended up getting rid of all the electronics inside and we just made use of the lamp casing. In order to make all the different colors we are using RGB LED strips so we had to remove the bulb too.

    So what's inside?

    What's Inside?

    The lighting is made with an RGB LED strip. This kind of LEDs actually have three different LED packed inside, one red, one green and one blue. By mixing up the light and brightness of each one of them you can obtain any color you want. For example, to make a white light we have to turn on all three LEDs with the same intensity, and, if we turn off the blue LED, mixing just red and green, we would have a yellow light.

    As we said before, we replaced the bulb with a couple of LED strips that are glued to the lamp and connected through the lamp's arm to the Arduino board. The LED strip have for pins: one for each color (red, green and blue) and one for power (12V). The blue, red and green cables are plugged into the pins number 9, 10 and 11 of the Arduino, and the power pin is plugged into the Vin.

    We removed the power cable too, and instead we used a 12V AC Adapter. This voltage is needed for the LED Stripes, and is available on the Vin pin.

    The wireless identification is made with our RFID 13.56 MHz Module (XBee Socket). This module allows to read and write different cards. The reader antenna is glued to the casing, under the lamp's base, so it can easily read the tags. It has an Xbee Socket, that means it can't be plugged directly to the Arduino Board.

    RGB LED Lamp

    To do so the module is connected to a Communication Shield. This shield allows to use XBee or our Bluetooth and RFID modules. The Communication shield is then attached to the Arduino board.

    Five 13.56 MHz cards are used to choose the color of the lamp. You can re-write this cards to change the stored information, so we assigned to each card a unique identification. That way, whenever you place one over the reader, the card automatically sends the data stored in its chip and the reader transmits the info to the Arduino Board. Depending on which card we are using it lights up a different color. One card is used to choose a random and changing color. It keeps that color until it detects another valid card.

    You can see the LED Lamp working on this video:

    Give it a go

    This project was developed following our RFID 13.56 MHz Tutorial. We are glad to share the code with you:

    if (state == 0)              // if so, we can be sure that we read correctly one UID
       {
          // search if the read card is inside the data base
          card = search(vCards, _UID, nCards); 
                                
         if (card != -1) {                    // if so, this is one of OUR cards
           Serial.print("\r\n  Card number ");
           Serial.print(card);
           Serial.print(" identified. Access granted.");
           hits[card]++;                      // add one more hit for the read card
    
           if (card == 0){
            Serial.println("Rojo");
            digitalWrite(9,HIGH);             //azul
            digitalWrite(10,LOW);             //rojo
            digitalWrite(11,HIGH);            //verde
      
           }
    ...

  • Arduino Resistor Cutting Robot - CH Team HacksMarch 31, 2015

    Today we bring you a project built by Pablo (surely you remember Pablo, don't you?), who works in the production department of Libelium. They go through a lot of resistor tapes every day in this department and they have to cut them manually with scissors so they can handle them more comfortably. This certainly takes a little bit of time and effort and he thought there had to be a way of making this easier and faster.

    And what better way than Arduino?

    Searching for a solution he came up with a resistor cutting robot controlled, obviously, by Arduino. He built his own robot based on the prototype made at Oomlout. This was an open source project, so, if you want to give it a go yourself, you can download the design files for the housing here.

    Arduino Resistor Cutting Robot

    He used a cnc machine to cut the wood fiberboard to assemble the housing for the robot and to make every part in the machine.

    To load the resistors there is a groove that is approximately as wide as the resistors tape, so it keeps the tape centered at every moment.

    A stepper motor controls a set of rollers and gears to move the resistor tape forward and then it stops after a preset number of steps. You can choose how many pieces you want in your tape by setting up the specific number of steps that the motor has to turn.

    After the set group of resistors have moved past the blades the stepper motor stops, and two servos control a pair of box-cutter blades to slice both sides of the tape. Servos can be precisely controlled and positioned so they're perfect for this purpose: the blades move down and, in the end, outwards to slice both sides of the tape, providing this way a more maneuverable strip.

    Check the video!

    You can see the Arduino Resistor Cutting Robot in action in this video.

    OK, I like it. Where is the code?

    The robot is controlled by an Arduino Uno Board and an A4988 driver is needed for the stepper motor.

    We are happy to share the code with all of you, our fellow readers.
