Near Field Communication - Physical Computing with Raspberry Pi. Difficulty: advanced This tutorial will have you make a coil for NFC and connect it up to your Pi.

Documentation - RFID/NFC 13.56 MHz shield for Raspberry Pi tutorial. Tutorial Index Introduction RFID (Radio Frequency Identification) is a technology that uses electromagnetic fields to identify objects in a contactless way; it is also called proximity identification.

There are 2 elements in RFID communications: the RFID module (or reader/writer device) and an RFID card (or tag). The RFID module acts as the master and the card acts as the slave; this means the module queries the card and sends instructions to it. In a normal RFID communication, the RFID module is fixed and the user takes his card near it when he needs to start the interaction. USB RFID + Python + Pub-Sub (MQTT) Raspberry Pi Home Server.

Autre aspect du monitoring de serveur, c’est la consultation des logs générés par les services qui fonctionnent.

Le problème, au fil du temps, les fichiers de logs sont nombreux et fastidieux à parcourir. Cependant, il est important d’effectuer cette tâche afin de savoir si tout fonctionne correctement et d’anticiper des besoins de maintenance.

Twofer Tuesday: Incredible PBX for RasPBX on BeagleBone Black and Raspberry Pi. We never were big fans of unfinished projects.

And with Festivus behind us and Christmas tomorrow, it seemed only fitting to celebrate with a Twofer Tuesday Encore. Whether you like ‘em or hate ‘em, Google’s free text-to-speech engine is a big deal. It’s as close to perfect as any commercial product you can buy. So getting it to work with the BeagleBone® Black was really important for those of us that believe the BeagleBone Black is a near perfect telephony platform for home users and SOHO businesses. Turn a Raspberry Pi into a Multi-Room Wireless Stereo. A Raspberry Pi controlled mini CNC Laser engraver [keep updating]

I recently made a mini CNC laser engraver using two DVD drives salvaged from old computers and <$10 extra parts bought on eBay.

The controller of the CNC machine is a Raspberry Pi, a $35 credit card size computer. The engraver turns out to be pretty successful. So I am sharing it with everyone. There have been a lot of examples people using Arduino to control CNCs. You can probably find tons of C programs available that run directly on Arduino to process G code.

Let’s break down what we’re doing with this wiring diagram in a little more detail.

First, let’s look at this one charger, battery and panel at a time. We’re using the newer version 2 of the USB / DC / Solar Lithium Ion/Polymer charger from Adafruit. You can click through to see the example provided on the project page that shows how to wire up the solar panel, battery and load connections. PrivateEyePi – a DIY home alarm system. A big thank you to Recantha for spotting this one: PrivateEyePi is a project that went straight on my “I MUST make one of these” list when I saw it.

Right now, that list includes an aerial Pi and camera board with the IR filter removed to take pictures of Iron Age sites in inaccessible bits of Cornish moorland; an Airplay-alike MagicPlay receiver; a garden irrigator and an Ambilight clone for the TV. I need a holiday so I can work on all this stuff – there just aren’t enough hours in the day. PrivateEyePi is an open, configurable, automatable home alarm system that you can build and program yourself. Its maker (identified only as “Gadjet Nut”) has documented the whole system minutely and provides parts lists and pricing; wiring schematics; and all the code you’ll need. You can use motion detectors, or switches attached to doors, or a mixture of the two. Click on the images to visit the PrivateEyePi project, and let us know if you decide to hack your own alarm system together. Onion Pi.

I’ve had a Raspberry Pi lying around the house for a few months now. Every once in a while I’ll take it out and tinker around with it. When BitTorrent released the BitTorrent Sync Alpha a few weeks back, I decided to see what kind of options I had for using the program with my Raspberry Pi. BitTorrent Sync is awesome.

The Delta-Sigma Pi is an 8 channel analogue to digital converter designed for use on the Raspberry Pi computer platform. The board is based around the MCP3424 low noise and high accuracy 18 bit delta-sigma analogue to digital converter from Microchip Technology Inc.

A pair of MCP3424 converters are included on the board along with an I2C buffer interface allowing you to connect additional 5V I2C devices to the same bus. The I2C address bits are selectable using the on-board jumpers. The MCP3424 supports up to 8 different I2C addresses so with two A/D converters on each Delta-Sigma Pi you can stack up to 4 Delta-Sigma Pi boards on a single Raspberry Pi giving you 32 ADC inputs. The MCP3424 contains an on-board 2.048V reference voltage with an input range of ±2.048V differentially (full scale range of 4.096V/PGA). The data rate for analogue to digital conversions is 3.75 (18 bit), 15 (16 bit), 60 (14 bit) or 240 (12 bit) samples per second. Untether Your 3-D Printer With a $35 Raspberry Pi. A RepRap controller running Pronterface on a Raspberry Pi. Photo: WDZaphod While most people still have trouble setting up an inkjet printer on a wireless network, a group of intrepid IT hackers are making big strides with far more advanced machines, using the tiny Raspberry Pi microcomputer to untether laptops from their 3-D printers.

Zachary Bales is an undergraduate studying electrical engineering and physics at Cal State Long Beach. He got into building a RepRap while acting as president of his engineering class. 3-D printing technology felt futuristic, but leaving a laptop attached to a printer for the duration of a modest five-hour print job seemed as dreadful as history class. Carrier connect shout out. Cottonpickersplace. Dr. Monk's DIY Electronics Blog: Raspberry Pi and Breadboard (Raspberry Leaf) I thought I would share this little helper I have made to simplify using the Pi with jumper wires. If you are using your Raspberry Pi with Breadboard, and you have lots of connections to make, then the Pi Cobbler from Adafruit is pretty neat. However, sometimes you only need to make a couple of connections and the Cobbler is overkill and a few Male to Female jumper leads will do just fine.

The drawback with using Male to Female jumpers direct onto the GPIO is that you then have to count down the pins trying to find the pin you need, because nothing is labelled. Matching a diagram of the pinout to the actual pins is not easy and mistakes can be made. Enter the Raspberry Leaf! To fit it onto the GPIO pins, I found it easiest to make the holes first by placing it over some breadboard and pushing a header pin through each hole in turn. Pushing it all the way down to the bottom of the GPIO connector needs tome help from a plastic tool - or if you turn off your Pi and, use a small screwdriver. So you got a Raspberry Pi: now what? VoIP on Steroids: Introducing Incredible PBX 3.7 for the $35 Raspberry Pi.

It’s been a wild ride with the $35 Raspberry Pi®. In late October, sales of the Raspberry Pi topped two million in less than two years. And, if you didn’t already know, the Raspberry Pi makes a near perfect platform for your very own VoIP PBX. It’s less than a ONE HOUR project! If you’re new to the party, imagine squeezing a 700 mHz ARM processor with 512MB of RAM, 2 USB ports, a 10/100 Ethernet port, an HDMI port, composite video, a separate audio jack, an SDHC card slot, and a micro USB port onto a motherboard the size of a credit card weighing 1.6 ounces. Adding WiFi is as simple as plugging in a USB adapter. Absolute perfection. Trust us when we say the performance of this tiny computer is nothing short of amazing. Raspberry Pi Quick Start Guide.
