How to Clone Raspberry Pi SD Cards Using the Command Line in OS X

How to Clone Raspberry Pi SD Cards Using the Command Line in OS X
The Raspberry Pi runs from an operating system stored on a Secure Digital (SD) card and many different operating systems may be employed. Storage is relatively inexpensive, can be created (flashed), recreated, written to and overwritten with ease. On the one hand, this is an advantage of the Pi. On the other, the experimental nature of the Pi means more time flashing SD cards. This tutorial shows you how to use a Mac to clone any Raspberry Pi SD card which is particularly useful when you have your OS set up just as you want it. The Raspberry Pi is somewhat different to the computing, to which most of us have been accustomed, of the last two decades. With almost two and a half million units sold–in little over a year since its launch–and with its focus on getting kids (adults?) Being able to experiment, play and break things is all part of the fun. Cloning is the process of making an exact copy. Open Terminal and enter the following command to locate your SD Card:

ESP8266 Note: This page contains information on using an ESP8266 module with an Espruino board. If you want to run the Espruino Firmware directly on an ESP8266 board, see this page instead Support is provided in Espruino by the ESP8266WiFi (About Modules) and ESP8266WiFi_0v25 (About Modules) modules. Different versions of the ESP8266 firmware communicate at different baud rates and have subtly different commands - make sure you use the ESP8266 module that corresponds to the ESP8266 firmware version that you have. Espruino Pico Shim Freematics – OBD-II Adapter for Arduino This product works as a vehicle OBD-II data bridge for Arduino (literally all embedded platforms) with open-source Arduino library provided. Besides providing easy-to-use OBD-II data access, it also integrates 6-axis or 9-axis MEMS sensor module and a voltmeter for measuring vehicle battery power. The adapter draws power from OBD-II port and convert it to 5V for powering attached device. Features

File sharing with OSX I never really enjoy Samba (who does?) and I do not have Windows machines but I do want easy file sharing with my Mac running OSX Lion. TimeMachine setup is included. The distribution I used this for is Raspbmc, it should work fine on Raspbian but mind the /media directory notes later on. Updated: 20-06-2013 (ddmmyyyy ofcourse..) PowerBoost 500 Charger - Rechargeable 5V Lipo USB Boost @ 500mA+ ID: 1944 - $14.95 PowerBoost 500C is the perfect power supply for your portable project! With a built-in battery charger circuit, you'll be able to keep your project running even while recharging the battery! This little DC/DC boost converter module can be powered by any 3.7V LiIon/LiPoly battery, and convert the battery output to 5.2V DC for running your 5V projects. If you need a 1A battery charger, smart load-sharing, and 1A iOS resistors, check out the Powerboost 1000C Like our popular 5V 1A USB wall adapter, we tweaked the output to be 5.2V instead of a straight-up 5.0V so that there's a little bit of 'headroom' for long cables, high draw, the addition of a diode on the output if you wish, etc. The 5.2V is safe for all 5V-powered electronics like Arduino, Raspberry Pi, or Beagle Bone while preventing icky brown-outs during high current draw because of USB cable resistance.

My Slim 2AA Battery Node Board releases(other colors might be selected when ordering) Version 2.0 (black) [order] Now designed in KiCad. "Final release". I'm not developing it further atm, but I know others have some projects going.Version 1.4 (red) My latest version in Eagle. Known issues are wrong references due to panelization and broken circuit diagram links.Version 1.2 (blue) Some less convienient placed components and the panelized verision has a faulty via.Version 1.0 (green) The one described below in this first post.

WoT with Arduino for Beginners: Part 3 - Connecting to the Internet via WiFi Download - 11.5 MB In this multi-part tutorial we show how to develop Arduino-based apps for the Web of Things (WoT). This third part shows how to set up a connection between an Arduino and the Internet via a WiFi network and use HTTP(S) to send data to a free cloud service like ThingSpeak. In the following parts of this tutorial, which will appear every 1-3 weeks, we discuss how to control actuators and connect them all together in a Web of Things (WoT) app.

LYT8226: an Arduino LED Bulb based on ESP8266 WiFi Working with the ESP8266 is always a great experience, it becomes just a matter of getting the proper I/O and then in few minutes your module is running. The introduction of the ESP8266 in the supported SoC for Souliss has open the world of smart devices to the DIYers and the very competitive price of this IC will spread it into consumer products. In the last few days we have started working with Authometion to support the new LYT8266, a variant of their RGBW LED Bulb that has an ESP8266 inside, so that you should program your sketches directly into the lamp (this is in contrast with the approach used with LYT88).

Touch Display for Raspberry Pi We add to Raspberry Pi a TFT touch screen to display the system console, movies and favorite photos or control a relay board … at your fingertips, literally! To avoid using an HDMI monitor the cost well above that of Raspberry Pi, in previous articles we have always gone the way of connecting remotely to the microcomputer, using tools such as Putty and WinSCP. This approach has always bound to use Raspberry Pi in a “server” mode. Therefore we have always presented applications with user interface built to be accessible by web browser. What to do when we want to have an interface in traditional style, accessible directly from the desktop?

tweeq Miniature Arduino Boards And Modules Developers, hobbyists and makers that enjoy building projects using the Arduino programming platform may be interested in a new micro sized Arduino boards system called tweeq that has launched over on the Kickstarter crowdfunding website this week. tweeq are powerful open source micro-sized Arduino boards providing a wide range of tiny add-ons to help build and expand your Arduino projects. Watch the video after the jump to learn more about the tweet project and see it in action. The tweeq Arduino Boards project are currently over on the Kickstarter crowd funding website looking to raise enough pledges to make the jump from concept to production. “Introducing tweeq cores. They might look tiny in the palm of your hands, but these little fellas boast a 32-bit micro-controller with loads of memory (up to 256KB!)

Liquid Flow Meter - Plastic 1/2" NPT Threaded Measure liquid/water flow for your solar, computer cooling, or gardening project using this handy basic flow meter. This sensor sit in line with your water line, and uses a pinwheel sensor to measure how much liquid has moved through it. The pinwheel has a little magnet attached, and there's a hall effect magnetic sensor on the other side of the plastic tube that can measure how many spins the pinwheel has made through the plastic wall. This method allows the sensor to stay safe and dry.

Using the Arduino Pro Mini 3.3V Favorited Favorite 3 Introduction The original, true-blue Arduino is open-source hardware, which means anyone is free to download the design files and spin their own version of the popular development board. SparkFun has jumped on this opportunity and created all sorts of Arduino variants, each with their own unique features, dimensions, and applications.
