PiFace – Raspberry Pi Interface. Gpio - What advantage does the Pi-Face addon board bring to the Raspberry Pi. It offers a pre-made board (the trade-off is price) that isolates the GPIO pins and protects the Raspberry Pi from damage.

It also provides additional/enhanced capabilities to the basic in/out offered by the Raspberry Pi's GPIO (it includes two relays to control larger power drawing devices, and allows you to connect a variety of sensors to allow the Raspberry Pi to sense and react to its environment - light, ultrasonic, water, etc). What you do with these extra capabilities is really up to you.

The Raspberry Pi and its developing ecosystem are fairly new, but the philosophy is similar to that of the Arduino or even Legos give the user the basic building blocks and then let their imagination and ability guide them. Using android phone's sensors on raspberry pi. You can try using this app.

It sends data from the sensors in UDP. It would only give you the information from the Accelerometer from the list you wanted. Sensor id: 3 - Accelerometer (m/s^2) 4 - Gyroscope (rad/s) 5 - Magnetometer (micro-Tesla uT) Example UDP packet: 890.71558, 3, 0.076, 9.809, 0.565, 4, -0.559, 0.032, -0.134, 5, -21.660,-36.960,-28.140 Timestamp [sec], sensorid, x, y, z, sensorid, x, y, z, sensorid, x, y, z. Configuring the Android ADB. Windows: Instala ADB, Fasboot y drivers Android para Windows en tan sólo 15 segundos. Si eres un usuario avanzado de Android sabrás a qué nos referimos cuando hablamos de ADB, de Fastboot o de los drivers Android y también sabrás que la configuración inicial del entorno suele conllevar bastante tiempo ya que tenemos que descargar numerosos paquetes por separado o el kit de desarrollo oficial y configurar los directorios de funcionamiento.

Windows: Instala ADB, Fasboot y drivers Android para Windows en tan sólo 15 segundos

El usuario de XDA-Developers Snoop15 acaba de lanzar un paquete para Windows que permite la instalación y configuración de ADB y Fastboot, así como los drivers para Windows en cuestión de sólo 15 segundos. Te presentamos ADB Installer. Se trata de un pequeño paquete que te permite instalar los componentes por separado, o bien, todo el conjunto de herramientas desde un sencillo menú en línea de comandos.

Si quieres empezar a trastear con tu smartphone, este kit es más que recomendado por su facilidad de uso y eficiencia. Instalar SDK y ADB Android, para principiantes. Aquí les dejo un excelente manual que explica como instalar el SDK de Android y como utilizar ADB, que lo necesitar para realizar ciertas modificaciones en su Android.

Tras el salto el manual y los archivos necesarios. Paso 1, el SDK Necesitaremos la última versión del SDK que nos ofrecen. Estas siglas corresponden a Software Developement Kit, y dan nombre a lo que podríamos llamar, la aplicación para desarrollar aplicaciones (valga la redundancia). INSTRUCTABLES: Raspberry pi loves Sensors and LEDs. Make sure the tools are installed... to test if the tool are installed run the following command..sudo i2cdetect -y 0 this will scan all devices connected to the I2C bus. it should look like the pic below. if you see that i2ctools are not installed run the following comand sudo apt-get install i2c-tools also install.

Making the electronics for a $7 USD doppler motion sensor - Limpkin's blog. I had no idea that you could find this kind of motion sensors on the internet for so cheap...

Making the electronics for a $7 USD doppler motion sensor - Limpkin's blog

But they come with a catch: you need to design some electronics for them. I'm sure you're quite familiar with the Doppler effect: you send an RF signal at a given frequency to a target, and if this object/person is moving the reflected signal's frequency will be shifted. This is the reason why a fire truck's siren has a higher pitch when the truck is going towards you than when it is going away. Anyway, this is the module you can find on ebay: You'll notice the 4 patch antennas to send/receive the 10.525GHz. HB100 doppler module with backpack from limpkin on Tindie. We recognize our top users by making them a Tindarian.

Tindarians have access to secret & unreleased features. Their product listings are automatically approved, and do not have to wait for our approval process. How does one become a Tindarian? We look for the most active & best members of the Tindie community, and invite them to join. HB100 Microwave Doppler Motion Sensor X-Band Radar Wireless Module $8.02 Free Shipping. Making the electronics for a Doppler motion sensor. There are many different sensors that can be used to detect motion in a given environment.

Making the electronics for a Doppler motion sensor

Passive InfraRed (PIR) sensors are the most used today, as they work by detecting moving heat signatures. However, they are less reliable in the hotter days and obviously only work for animals and humans. Sensors like the one shown in the above picture started to appear on the internet, they use the doppler effect to detect motion. I (limpkin) designed the electronics you need to add in order to get them to work. Here is a simple explanation of the doppler effect: if you send an RF signal at a given frequency to a moving target, the reflected signal’s frequency will be shifted.

The Doppler motion sensor I bought only outputs a non-amplified signal of a few micro-volts, whose frequency represents the speed at which an object is moving towards or away from the sensor. Experiments with Doppler Microwave Sensor. X-Band (10.525 GHz) Doppler Microwave Sensor with NI USB-6009 Data Acquisition Device.
