The internet of trees makes smart birdhouses using Arduino Yùn

via Arduino Blog

tumblr_inline_nbjvwkqaDW1rxqn91

The connected birdhouse is a project prototyped during a workshop ran by Massimo Banzi at Boisbuchet, last August in France. It was developed using Arduino Yùn, by Valentina Chinnici, who shared with us the project, and two other students taking part to  the week of learning-by-doing around the theme of  the Internet of Trees.

They redesigned a traditional object, a wooden birdhouse to be placed outdoor, and connected it to a lamp shaped like a nest, to be placed indoor:

The connected birdhouse was in fact an interactive object able to communicate to the nest/lamp the presence of a bird inside the house, and accordingly to a color coded signal was giving also some informations about the size of the bird itself. In the event of a bird entering into the house, the nest/lamp remotely controlled via WiFi by an Arduino Yùn, was turned on. The nest/lamp received the notification from the birdhouse translating it firstly with a rainbow effect. After few seconds the light changed according to the weight of the bird (green, yellow or red).

The LED strip used for the nest lamp was an Adafruit Neopixel strip controlled by an Arduino Yún.

On this blog you can find the sketch to make it work and create one yourself.

Arduino Tour goes to London: 21st of September – Workshop on #Iot

via Arduino Blog

arduinoPlant

Next 21st of September Arduino Tour is finally landing in London for a one-day workshop, starting at 10am at The Maker Works London, UK. (max. 18 people).

This edition of the official Arduino workshop is focused on the world of the Internet of Things and will allow participants to experiment with a botanical kit including an Arduino YÚN, plants and sensors. The workshop teaches you how to turn your plants and virtually any object into connected, responsive elements using Arduino YÚN.

Arduino YÚN is the combination of a classic Arduino Leonardo and a small Linux computer, able to connect to a network or Internet via Ethernet or WiFi. Arduino boards are able to read inputs – light on a sensor, a finger on a button, or even a Twitter message – and turn it into an output – activating a motor, turning on an LED, publishing something online.

Pinoccio: Mesh All The (Internet Of) Things

via Hackaday» hardware

PinnThere’s a problem with products geared towards building the Internet of Things. Everyone building hardware needs investors, and thus some way to monetize their platform. This means all your data is pushed to ‘the cloud’, i.e. a server you don’t own. This is obviously not ideal for the Hackaday crowd. Yes, IoT can be done with a few cheap radios and a hacked router, but then you don’t get all the cool features of a real Things project – mesh networking and a well designed network. Pinoccio is the first Thing we’ve seen that puts a proper mesh network together with a server you can own. The Pinoccio team were kind enough to let us drop in while we were in Rock City last weekend, and we were able to get the scoop on these tiny boards from [Sally] and [Eric], along with a really cool demo of what they can do.

The hardware on the Pinoccio is basically an Arduino Mega with a LiPo battery and an 802.15.4 radio provided by an ATmega256RFR2. The base board – technically called a ‘field scout’ – can be equipped with a WiFi backpack that serves as a bridge for the WiFi network. It’s a pretty clever solution to putting a whole lot of Things on a network, without having all the Things directly connected to the Internet.

Programming these scouts can be done through Arduino, of course, but the folks at Pinoccio also came up with something called ScoutScript that allows you to send commands directly to any or all of the scouts on the mesh network. There’s a neat web-based GUI called HQ that allows you to command, control, and query all the little nodules remotely as well.

In the video below, [Sally] goes over the basic functions of the hardware and what it’s capable of. [Eric] was in Reno when we visited, but he was kind enough to get on a video chat and show off what a network of Pinoccios are capable of by emblazoning their web page with Hackaday logos whenever he presses a button.

Open Source Hardware Camp 2014

via OSHUG

Open Source Hardware Camp will take place in the Pennine town of Hebden Bridge. For the second year running it is being hosted as part of the technology festival, Wuthering Bytes. However, this year OSHCamp will have the Waterfront Hall to itself on the Saturday and Sunday, with a separate Festival Day taking place on the Friday and with talks on a broader selection of technical topics.

Details of the OSHUG talks and workshops can be found below and the Wuthering Bytes website will be updated in due course with details of the complete programme of events.

Note that socials are planned for both the Friday and Saturday evenings, with the former being hosted at the Town Hall and where there will be a bar, food available and music and a live performance, and the latter will be hosted at a local hostelry that serves food.

Hebden Bridge is approximately 1 hour by rail from Leeds and Manchester. Budget accommodation is available at the Hebden Bridge Hostel, with private rooms available and discounts for group bookings. Details of other local accommodation can be found at www.hebdenbridge.co.uk.

Any questions should be directed to the Discussion List.

Saturday :: Talks

Linux bootloaders and kernel configuration

Linux is popular in embedded devices, but most use it once the kernel has booted and don't consider how it was started. This talk explores just what happens when you first start an embedded device that is running Linux, and will look at common bootloaders, such as U-Boot, along with kernel boot options. Finally, we will look at useful kernel configuration options for embedded devices.

Melanie Rhianna Lewis started a life long love of electronics as a child when her Dad helped her make a "crystal" radio with an ear piece, a coil of wire, a diode and a radiator! At the same time the home computer revolution started and she would lust after the "build your own computers" advertised in the electronics magazines of the time. She never got one but did end up the proud owner of a BBC Micro. Melanie learnt everything she could about the machine and including assembler, operating systems, drivers, interrupt, and, thanks to the circuit diagram in the Advanced User Guide, digital electronics. After the BBC Micro came the Acorn Archimedes and so started a long relationship with ARM processors. In the 90s Melanie became interested in Linux and then developed one of the first ARM Linux distributions running on an Acorn RISC PC. The hobby became a job and Melanie currently works for an embedded device consultancy near Bradford where a lot of her work is still with ARM processors. Recently Melanie became a sporty person and now spends a lot of her time hitting girls. She will probably bore you with tales of roller derby!

Open source archaeological geophysics - is it achievable?

The advance of technology into Archaeology has allowed geophysical surveys to "peer into the ground" and direct the diggers to the most likely "targets". However, as anyone whose watched Time Team will know, using Resistivity and Magnetometry doesn't always guarantee results. Such equipment is not usually within the financial reach of most hobbyists. However, the recent explosion of the Arduino, Pi and other cheap electronics has meant making such surveying equipment may be possible.

A small research project involving an informal collaboration between members of the Derbyshire Archaeological Society (DAS) & Derby Makers is exploring whether a high accuracy GPS unit, Magnetometer and a resistivity probe can be made and yield worthwhile results within a budget of £1,000. DAS has kindly funded this research and we are about 50% of the way through the GPS project. This talk will introduce the project and take a look at progress to date.

Tony Brookes was firstly an engineer and then worked in IT for a while (!) Now working part-time, hobbies easily fill the time available. Drawn to archaeological and historical research by way of Time Team, he now tries to apply open source software (Scribus, Inkscape, Qgis) and hardware (Arduino, et al) to investigating parish history and other interesting topics.

An open source aquaponics control system

Aquaponics is a closed system of food production that farms fish alongside vegetables, and this talk will look at the development of an open source aquaponics control system for the Incredible AquaGarden project in Todmorden, highlighting certain features of the design and exploring some of the difficulties encountered and how these have been addressed.

A control and monitoring system with an event-driven 'flowchart' interface will be presented, where data about aspects such as pH, temperature and light level etc. are collected and logged in order to monitor the environment. The system responds dynamically to control the level of water in the plant growing bed, to maximise the yield. Some design decisions and technical aspects of the system will be demonstrated and discussed, together with the open source model for sustaining the project.

Finally, we will look at the operational Node-RED installation in Todmorden, showing how the system is collecting readings and controlling the water level, and we'll talk about how MQTT has been used to loosely couple the code running on the Arduino with Node-RED on a Raspberry Pi.

Gareth Coleman is a inventive hardware hacker who's talent lies in connecting diverse devices. Dr Naomi Rosenberg is a freelance software developer with a background in formal logic who works on a wide variety of platforms. They both get a especially enthusiastic about open hardware, free software and empowering humans.

From Idea to Finished Product: A Tale of DFM and CEM

With numerous easily accessible embedded platforms around and concepts such as rapid prototyping and crowdfunding now being useful things as opposed to just buzzwords, designing the Next Big Thing without leaving your study is becoming a common story for makers and tinkerers.

While it is true that going from an idea to a finished product has never been easier thanks to the abundance of design resources and affordable manufacturing services, designing for volume manufacturing requires a different mindset that usually does not apply to casual weekend hacks. From component choice to packaging and logistics, there are several elements that needs to be taken into consideration, as they may cause significant headaches otherwise.

This talk will provide an overview of electronics manufacturing process, covering details such as managing design data, handling dependencies, component and process choices, testing and certification and several other aspects of DFM: Design for Manufacturability.

Omer Kilic is an Embedded Systems hacker who likes tinkering, a lot. He also likes tiny computers, things that just work and good beer.

Driving milling machines with Linux

Driving a milling machine with Linux is fairly easy and LinuxCNC (previously known as “EMC”) even provides a real-time distribution install disk. However, driving the machine is only half the story and gcode generation is at least as important.

This talk will share experiences using a mill and a router with Linux, looking at PCB manufacture, engraving, 3D milling, casting, tool paths, materials, tools and parametric design.

Matt Venn has run hundreds of creative science workshops for thousands of children and adults around the world. For the last year, he has been working with teachers in preparation for the computer science curriculum changes; creating and leading courses, workshops and projects.

When he's not inventing new ways of getting people excited about science, Matt plays music, invents puzzle boxes, practices martial arts and maintains bikes.

Oxford Flood Network - easier to Apologise Than to Ask Permission

Oxford Flood Network is a citizen sensing project which monitors water levels around the city, in streams, rivers and even under floorboards, sending water levels back to the Internet using low-powered wireless.

The network explores the possibilities of a smart city that is created by its citizens, rather than a more typical top-down deployment. Sensor networks are generally used to collect data about us for reasons and agendas chosen by others, but we can build sensor networks too; crowd-sourced data can be gathered for your agenda — providing evidence for your issues.

In this talk we will hear how Oxford Flood Network has developed an open source model for hardware and software, and the challenges of sticking mysterious boxes under bridges.

An introduction to writing applications for the Parallella board

Parallella is a credit card-sized computer with a many-core accelerator that allows it to achieve high floating-point performance while consuming only a few watts. In this talk we will take a look at the Epiphany architecture and how to use the eSDK to write highly parallel applications for it, using hardware and software features to benchmark code and optimise performance.

Radio Then and Pararchive: decentralised, pervasive, and open story telling

Radio Then is a citywide cultural history experience, telling stories about Manchester’s jazz and popular music heritage using a small, Arduino-powered radio. Participants explore the city and tune in to archival broadcasts related to places, people, and events of note. In actual fact, the ‘radio’ contains GPS and audio breakouts to track its location and cue audio tracks depending on its coordinates.

The project is being created to showcase findings from Pararchive, an AHRC project being conducted by the University of Leeds, in partnership with the BBC, National Media Museum, Science Museum Group, and Manchester Digital Laboratory, among others. Pararchive represents an opportunity for members of the public to engage with archives, decentralising the material from archive holders, and offering alternative and personal perspectives on events.

James Medd is an artist, musician, and maker based in Manchester. He teaches all things digital in the north west of the UK, and creates whimsical, entertaining, and accessible interactive artworks. He currently leads Arduino Manchester, a community group for Arduino users in Manchester, and will be developing more interactive audio experiences at Watershed’s Pervasive Media Studio later this year, as a winner of their graduate and new talent competition.

Commercialising your ideas

Whether you're taking the time to build something fun, or have a solution to a problem you have faced, you are 'in your own right' an inventor.

One of the biggest challenges inventors face isn't making their product work, it's generating a living to continue inventing. Having spent over a decade in both sales and business development I have witnessed people use various methods to overcome this hurdle. I hope to share with you some of my experiences to provide you with some ideas you can take away and use when looking to turn a hobby or bright idea into a financial success. Our topic of conversation will take us from having a light bulb moment, to securing orders and reaping the rewards.

OpenTRV: energy technology that saves householders money

The OpenTRV project aims to provide software, hardware designs and excellent interoperability to allow UK and EU householders to as much as halve their heating bills and carbon footprint with simple to fit hardware costing around £100 per house. Everything is freely available under liberal licensing — even our 3D printed enclosures — to enable adoption and cost savings.

Damon Hart-Davis gets excited about electronics, parallelism, robotics, distributed systems and resource efficiency, and solar PV and halving space-heating carbon footprint with cheap microcontrollers (OpenTRV) are two of his current passions. Damon has been working on “mission-critical” systems in banking for most of the last 20 years and before that founded one of the first UK Internet Service Providers.

Interfacing with SPI and I2C

SPI and I2C are industry standard methods of interfacing IO devices to micro-controllers and CPUs using just a few connections. SPI requires four wires and I2C just two.

This talk introduces SPI and I2C. It describes how they work and how you use them. It will look at common IO devices that connect via SPI or I2C. Finally it will look at controlling SPI and I2C devices from two example controllers, the Arduino and the Raspberry PI, in languages such as C and Python.

Speaker: Melanie Rhianna Lewis.

Introduction to Baserock

Baserock is a new set of open source tools for creating "appliance" operating system images. The aim is to close the gap between source code repositories and the code running on a device. This talk will go over Baserock's philosophy, what it provides and how you can try it out today.

Sam Thursfield likes it when technology is surprising in a good way but does not like it when it is surprising in a bad way. He spends a lot of time trying to reduce the amount of code that is required to do things. He has been known to play the trombone in and around Manchester.

Concurrency in the real world with xCORE and XC

There are many cases where a simple microcontroller won't cut it and the FPGA design route may be too drawn out and costly, particularly if your background is in software.

With the XMOS multi-core microcontroller architecture and toolset it's now possible to tackle complex hardware problems using familiar software and algorithms, avoiding the need to work with Verilog or VHDL. The XMOS XS1 microcontrollers provide tens of nano second resolution and deterministic, predictable, real-time operation in software. The XMOS toolset enables designs to be simulated and analysed, and signals to be monitored and scoped all within the IDE.

The XC extensions to C provide simple interfaces and tasks to write concurrent programs, taking care of nasty race conditions and parallel usage errors. xCORE open source libraries help break down complex domain-specific tasks, allowing you to focus on developing applications. While XMOS Links enable microcontrollers and boards to be chained together in a divide and conquer manner, allowing you to orchestrate your own hardware solutions.

This talk will introduce the XMOS technology and explore a selection of real world applications.

Alan Wood has been working with concurrent and distributed programming for over a decade. His recent work includes smart grid, control, and motion systems based on XMOS' concurrent technology. He is a long term advocate and moderator (aka Folknology) for xCORE and other SHW communities, such as TVRRUG, as well as a founder of hackspace, SHH.

  • Internet of things with Arduino Yún and Yaler

    via Arduino Blog

    ArduinoYun and Yaler

    Explore this tutorial  demonstrating how the Arduino Yún can be controlled from anywhere with any internet connected web browser. The solution is provided by Bo Peterson using the Yaler service which means that the Yún can be reached from any network without knowing the IP-address, and without any port forwarding on the router where the Yún is connected.

    A common problem in home automation and internet of things applications is that it is difficult to reach devices connected behind wifi routers from the outside. There are different approaches to overcome this problem:

    • Port forwarding and static ip addresses. This solution requires the user of the connected device to know how to configure a router and have access to router administration which is not always possible. A Yun tutorial with port forwarding is found here.
    • Polling is a technique where the connected device at regular intervals checks with an external server if the device should take action. This solution requires no configuration of the router but it creates extra network traffic and response delays.
    • A third way is to use WebSockets which is a way of providing real time full-duplex communication over TCP. Spacebrew is a good open source toolkit for connected devices using WebSockets. Autobahn is another infrastructure that can be used.
    • Reverse HTTP is the solution that will be used in this tutorial. We will use Yaler which is an open source relay infrastructure that gives access to connected devices with very little configuration.

    Follow the tutorial and get the code at this link.

    Internet of Everything – Flip the Switch and Get Going

    via Arduino Blog

    Temboo Iot

    Our friends at Temboo are releasing more cool stuff for your Internet of Everything. Here’s some news from their blog.

    ———————————-

    Now you can connect even more Arduinos with the power of Temboo by simply flipping our IoT Mode on. This new feature opens up a whole new world of possibilities for the Internet of Things.

    What is IoT mode, you ask?

    It’s a new way to access our 2,000+ Choreos on any of your Arduino or Arduino-compatible boards. By just hitting a switch at the top right of any Choreo page, you “got the power” to call that Choreo with a sketch tailored specifically for the device you pick from our drop down menu. Previously, this feature was only available for the Yún, but now it is open to the larger Arduino family. All you have to do is select the type of shield your board uses and the code will generate accordingly.

    So how do I begin using this amazing IoT feature?

    Select a Choreo from our vast Library and turn on IoT Mode. In the example above, we chose the Data.gov API and the GetCensusIdByCoordinates Choreo. Data.gov is a cool way to access APIs from a number of US governmet agencies and to query government datasets, including the US Census!

    The “Arduino” option encompasses compatible boards that lack the Yún’s built-in wifi capabilities, but can connect to the internet with a shield. Fill out your shield’s specifics when the popup appears and save for future use. Run your Choreo and scroll down to retrieve the code for the sketch, ready to be pasted into your Arduino IDE. You can even plug this into a sketch generated by our nifty Device Coder to start mixing and matching!

    We are thrilled just thinking of all of the possibilities this unlocks for the Internet of Things. We want to hear all about what you cook up with this new capability, so if you are working on an interesting project, reach out to us at hey@temboo.com!

    Find out more on their blog!

    Arduino At Heart EZ Control for home automation goes wireless – 8 days left

    via Arduino Blog

     ezcontrol

    We’re happy to share with you the update of the Indiegogo campaign of the Arduino At Heart for home automation we presented some time ago. Ez Control goes wireless!

    ———————————–

    We have been silent for most of the time of this campaign, but this doesn’t means that we were sleeping. Not at all!

    We were listening and interacting. We have received your comments, we have followed the topic on Reddit, we have exchanged ideas with many of you and we spent all this time improving our product.

    Some of you was concerned about the relay, maybe too small. Some other concern was related to the position of the temperature sensor, that could offer false reading caused by the heat from other components.

    We have upgraded the relay with a new one, rated 5A, and we have also improved the physical insulation for the high voltage circuit. We have then improved the insulation of the temperature sensor.

    Sure all interesting, but those where not the main doubts about our hardware.

    The most requested upgrade was related to the connectivity.

    Why in 2014 do we use wires?

    We admit that going wireless it was in our plans for the future. We wanted to start with an easy to use board, affordable and based on well known technologies, open to most of the users.

    Reading and listening all your comments, we have understood that we should change our plan, and we did it.

    Yes! We spent the past month with design, engineering, prototyping and testing of the brand new and immediately available EZboard WiFi!

    This means that every perk and everyone will receive NOT the old board based on the cables and 10Mbit Ethernet controller, but this new, fantastic, WiFi development board.

    And the price will not change!!!

    James Bond villain-style alarm clock for the deaf

    via Raspberry Pi

    A quick post today: I’m in a tearing hurry trying to get our display for today’s UK Technology Industry reception at Buckingham Palace ready, in the face a few awkwardnesses. We’ve got an entire education team and half an engineering team that’s off sick with something we’re calling the Raspberry Flu, and an SD card that corrupted when someone who will not be named yanked the power cable at an awkward moment. Frustrated weeping commenced about thirty minutes ago, but I think we’re going to get everything sorted in time.

    Here is Kim Wall’s rather magnificent giant deaf alarm. It’s very feature-heavy, with a fire alert, an IRC interface, and the ability to hook up to other things around the house like the doorbell and phone. I’ve spent ages using my Google-fu to try to find out more information about it, but sadly all we’ve been able to come up with is this video, and the explanatory text next to it on YouTube:

    Over at YouTube, Kim says:

    Control is via the LCD and buttons, and also over the network via an IRC bot interface. Fire alerter and vibrating pad are FireAngel Wi-Safe2, which continues to operate if the clock fails.

    The clock is also a GPS-based Stratum 1 network time server, and is able to maintain accurate time without a working network connection.

    The clock will connect with other modules over the network for doorbell, telephone alerter, central heating control and various other features.

    Power is supplied at 48V in a IEEE 802.3af style, but as the Raspberry Pi lacks POE breakout, the passive POE dongle is required.

    We’d love to learn more about your setup, Kim; if you’re reading this, please drop us an email!

    Home Automation for Makers goes Arduino At Heart! Support them on indiegogo

    via Arduino Blog

    ezcontrol

    A connected home is in the dreams of many of us and we all spent at least a few moments thinking about how would it be for real. The problem is that most of the hardware devices and software platforms are not designed to work together and that’s why things become complicated.

    Today we introduce you to a new Arduino At Heart project called EZcontrol.IT, crowdfunding now on Indiegogo, and designed to simplify the world  of internet of things:

    EZcontrol.IT offers dedicated hardware that is affordable and easy to use, compatible and programmable with the Arduino™ IDE and language; designed to interact with a full and extensive software platform: Lelylan, that is an open, easy to use and personalize, cloud platform for Home Automation.

    The project is composed by:

    •  EZboard, a low power consumption Arduino compatible board, equipped with an onboard Ethernet controller, microSD card socket, temperature sensor, and power relay. It’s designed to run for long periods of time powered by batteries and it integrates all the hardware necessary to implement most of the common applications for Home Automation.
    • Leylan platform, a very easy to use Home Automation cloud platform, universally compatible with any device capable of being connected to the web. It’s  based on the MQTT protocol (MQ Telemetry Transport), the same used by Facebook to send live updates to the mobile messaging applications, and offers a simple API that can be used to program basically any platform.

    EZcontrol.IT decided to join the Arduino AtHeart program to better identify this solution as dedicated to makers, and to remark the compatibility with the Arduino platform at the highest possible level.

    EZboard in bundle with Lelylan is available starting today for a short initial period of pre-order, with packages for makers and extremely affordable early-birds offers. Make your pledge!

    WebsocketClient for Intel Galileo + Spacebrew

    via Arduino Blog

     

    intel galileo

    The SmartUp Team submitted on Intel Community a project developed in their new digital fabrication laboratory, tinkering with  Intel Galileo boards and Spacebrew.

    Spacebrew  is “an open, dynamically re-routable software toolkit for choreographing interactive spaces”, basically a way to connect smart objects of any kind using the WebSocket protocol.

    Basically, they modified the Arduino WebsocketClient library to use it with Intel Galileo and specifically with Spacebrew:

    The received situation was of a version of the Arduino WebsocketClient library: https://github.com/labatrockwell/ArduinoWebsocketClient (oriented to Spacebrew) adapted from: https://github.com/krohling/ArduinoWebsocketClient (implementing the online websocket protocol) neither of them supporting Galileo, an Intel SoC Pentium-based board. It has been revised, modified, and integrated, so that this version runs on Galileo and works for both the connection to a server such as echo.websocket.org and Spacebrew. This version includes extended tracing facilities for debugging (see WebSocketClient.h). The main changes with respect to the previous versions are marked by slash-slash-star-slash-slash.

    You can explore the library on Github.

    The Yún Way: less time debugging and more time inventing

    via Arduino Blog

    Back then secret device, back then secret Yun.

     

    Today I’m happy to welcome Sven Kräuter as guest blogger on the Arduino Yún, as part of a series of posts exploring different unique features of our new board.

    Sven works with Julia Kümmel focusing on agile & lean processes for soft- and hardware product development and together create projects at the intersection of the physical and the digital world, mostly using Arduino. His post below was orginally published at this link.

    —————–

    This summer I had a speaker engagement at the Codemotion conference in Berlin which I really enjoyed for many reasons. For starters Jule & me participated in an inspiring wearable computing workshop where we met Zoe Romano for the first time. The next day I talked about a possible and easy way how to build the internet of things.

    Presenting thoughts on & actions how to build the IOT.

    After the talk it seemed to appear like a a good idea to Zoe that I should get a sneak peek at some new Arduino hardware. There weren’t any more details since it was still secret back then. Of course it didn’t took me much time for consideration since I really love Arduino for making our hardware prototyping so much easier. I happily agreed on checking out this new mysterious device.

    The talk was about how to connect anything to the internet using an open source framework I initiated called the Rat Pack, so I assumed it had to do something with online connectivity or that something had to be connected to the internet. Turns out it was about both ;-) .

    Making things talk with each other online (source: slideshare).

    When Zoe told me about the Arduino Yún I was immediately stoked: an Arduino Board equipped with wi-fi, plus being able to access a small real time Linux system. How awesome is that? Exactly. I couldn’t wait to get hold of the Yún, and when it finally arrived it became quite obvious to me that I had a well thought and rounded product in my hands. Before I really knew what hit me this thing took shape on our balcony (see pic at the beginning of this post)

    I’ll skip the amazing deeper tech details if you don’t mind (Uploading via wireless LAN, remote debugging, SSH access, Ruby on your Yún…). If you do mind please tell me, I’m glad to blog about them too ;-) . I’ll just give you a rough outline of the journey I went through with the Yun so far.

    The first idea was to integrate it into the Rat Pack ecosystem. Adapting the Arduino client code of the rat pack was fairly easy, it simply uses Linux shell commands on the Yun instead of putting the HTTP command together in the Arduino C code. It’s just a small detail but dramatically reduces the complexity of your project. You don’t have to implement the HTTP calls yourself, you can rely on the work horse that Linux is.

    Being inspired by this first success with the Yún I thought maybe I could reduce complexity of the prototype of a device that we use to welcome guests at our place. I’m talking about the Bursting Bubbles Foursqaure Switch.

    Foursquare & Arduino powered soap bubble machine.

    When you check in to our balcony with foursquare, a soap bubble machine starts filling the air with bursting bubbles. The first prototype uses Arduino connected to an XBee Wifly to control the soap bubble machine and a Rat Pack server that handles the Foursqaure API.

    Initial approach with lots of moving parts(tm).

    Quite complex and actually and as you might have guessed the Yún helped reducing both the software and the hardware complexity drastically. Adding it to the project made it possible to cut off a lot of fat. Actually it now only consists of the Yun connected to the soap bubble machine.

    The Yun way.

    What’s true for the hardware is also true for the software. Have a look at the code base. Reduced comlpexity is achieved by processing the response of the Foursquare API on Linino as opposed to letting the Ruby server take care of it. And although there’s much debate when it comes to JSON processing with regular expressions in general, I just used grep and a matching regexp to extract the information from Foursquare’s JSON response. The parts marked green are the only ones necessary after adding the Yun to the setup.

    Losing some pounds. Or rather kilobytes…

    For us at making things happen the Yún will also be the platform of choice for our Internet Of Things workshops. Until now we use Arduinos and XBee WiFlys since they turned out to be the most robust solution for introducing a group of people to the principles of connecting things to the internet.

    Current ‘IOT Basics’ workshop setup.

    Although this works most of the time there is still time needed to wire things up and debug the hardware the participants build. With the Yún we can reduce the time necessary for setting things up and debugging the custom setup and use it to concentrate on spreading our knowledge on the subject. Actually you only need two wires for the basic Rat Pack example when using the Yún:

    Future workshop setup: drastically reduced wiring effort.

    So on the bottom line I see the Arduino Yún as a major milestone in making the internet of things available to a broader audience and empowering fellow makers and tinkerers to spent less time debugging and more time inventing.

    Less complexity = more time for creativity (source: twitter).

    It will also make our workshops far less complex and let the participants concentrate less setting things up and focus on their creativity.

    I did not use all of it’s features yet, I’m more than curious to explore more of it. The feature I’ll focus on next is the possibilities of actually using the pins of your Arduino via RESTful web service. I guess I’ll keep you posted about that. Thanks Arduino for this awesome device and thanks for letting me have a look at it a little earlier. It seems like the beginning of a wonderful friendship…

     

    Internet, Arduino, two men and a company

    Observos

     

    What defines a maker? A wish to make things , a quest for tools and ample creativity. They say that creativity has no bounds so what inspired this Ex-restaurateur to create a company Haxagonal Research with their much featured product Observos?  In people’s words words:

     

    Observos, a box that can monitor the temperature, humidity, and barometric pressure of a space and shuttle this information across the net.

     

    The company’s two founders Ronald Boynoe and Loren Lang both were pretty tech savvy, but it was the Arduino movement, which kickstarted their dream together.

    “Arduino provided us an extraordinary platform for testing against, an invaluable repository of preexisting libraries and other code that would have taken an incredible amount of time to write, and a lot of community support,” he says. “It has decreased our time to market, and significantly reduced our startup costs, allowing us to more rapidly develop new prototypes.”

    observos

    From having a restaurant as their first customer to diversifying into agriculture sector,  they define their biggest challenge as tuning the humidity sensor to a required precision.  Hexagonal at the moment has a presence here and here.

    Saturday Talks

    The Importance of Mini Makers

    14 year old Amy Mather discusses why the maker culture is so important to the younger generation and introduces us to her idea of a Mini Mini Maker Faire, where only under 18's would be able to exhibit their creations.

    Amy Mather, a.k.a. MiniGirlGeek, has been making and coding for 18 months with the guidance and support of the community that she found at Manchester's MadLab and hackspace. Amy was the closing keynote speaker at the world's first Raspberry Jamboree event, speaking alongside Professor Steve Furber and Pete Lomas of the Raspberry Pi foundation. Amy also presented at the inaugural event RSA FutureMaker event at London's Somerset House, where she also ran a workshop introducing attendees to the world of sewable electronics.

    Building a Maker Business: Sharing, Education, Open Source and Conscience.

    How open are you prepared to be when starting a business? Explore the wonderful shades of grey in the moral and legal landscape, as well as the risks and benefits to your survival in those early days, with war stories from Pimoroni's first year of existence.

    Paul Beech is a co-founder of Pimoroni, makers of the Pibow, Picade and other things Raspberry Pi. He also designed the Raspberry Pi Logo, and was somewhat responsible for the short-lived Interactive DVD phenomenon. He lives in Sheffield, in the Pimoroni workshop, because that's where all the good toys are. He prefers small-scale subtractive manufacturing processes.

    The @ShrimpingIt Manifesto

    Electronics engineers find it trivial to build an Arduino-compatible circuit on a breadboard using components which are just one tenth the cost of an official Arduino board. The @ShrimpingIt project curates open resources and projects so that everyone can progress their prototyping with simple components and materials, just like the experts. The approach delivers a whole host of benefits for those learning to prototype - not just saving money.

    We'll be introducing the project, sharing the choicest cuts from our year's experience running it, and featuring lots of the great spin-off projects people have built on our work. The @ShrimpingIt manifesto combines insights from open design and community engagement, arriving at a challenging standpoint of how beginner microcontroller projects should be designed, presented and taught for a better tomorrow.

    Introduction to Robot Operating System

    Robot Operating System (ROS) is an open source modular robot middleware. It is used in many many Universities and research projects around the world, and is starting to move into industry as well.

    This talk will provide an introduction to ROS, explaining what it is, how it works and some of the things it can do. There will also be a practical demonstration of a robot running ROS.

    Nick Weldin initiated the first public Arduino course in the UK in 2005, because he didn't want to program PIC chips on the accounts computer at work after everyone else had gone home any more, and he couldn't get his boss to send him to the Arduino course that was running in Spain. When Tinker London started up he joined them and ran courses teaching Arduino wherever anyone was interested. He is co-author of the Arduino Cookbook and now works for Middlesex University.

    Risking a Compuserve of Things

    More and more companies are staking a claim to be the platform for the Internet of Things. Should we be aiming for a more open Internet of Things? Is the platform for the Internet of Things not just the Internet? Adrian McEwen will be exploring some of the challenges in implementing the Internet of Things and suggesting ways to improve collaboration and interoperability.

    Adrian McEwen has been connecting odd things to the Internet since the mid-90s. Starting with cash registers, and then as part of the team who were first to put a web browser onto a mobile phone. For the past five years he's been working with the Internet of Things.

    Adrian founded MCQN Ltd, an IoT consultancy and product company, which is based in DoES Liverpool - a hybrid makerspace and office, which he set up with some friends. He's putting the finishing touches to a book — Designing the Internet of Things — and also working as CTO of start-up Good Night Lamp.

    Measuring Energy Consumption in Embedded Systems

    How energy-efficient are your programs and how long will your devices last on battery power?

    Particularly when writing bare-metal applications, we have a great deal of control over how much energy the processor and hardware connected to it consumes. In this talk I discuss how we can accurately measure the energy consumption of our devices, and techniques that we can use to extend battery life.

    James Pallister is a graduate of the University of Bristol, where he achieved joint First Class Honours in Computer Science and Electronics. During the summer of 2012, he led Embecosm's research program into the impact of compilers on energy consumption in embedded systems, which was a development of James' work at the University of Bristol with the XMOS multi-core processor.

    James returned to Bristol in October 2012, where he is studying for a PhD in low-power multi-core system design. He remains a Technical Advisor to Embecosm.

    Polling is for Wimps — Asynchronous Communications for the Internet of Things

    They say that, if the only tool you have is a hammer, everything looks like a screw. Don't get me wrong, I love REST. It's great for posting data and one-off access. However, REST is not a good way for IoT actuators to get their instructions from a controlling system. aul will discuss his experiences with Sockets, XMPP and MQTT. One of which will usually be a good solution for most implementations.

    In each case arguments for and against will be presented, in the context of systems that must operate in near real time with low power budgets. Relevant open source technologies will be referenced. For a case example we’ll use the MQTT system that Paul and Adrian Godwin have been building for an experimental, thermally-efficient new build home.

    Paul Tanner is a consultant, developer and maker in wood, metal, plastic, electronics and software. His day job is IT-based business improvement for SMEs. By night he turns energy nut, creating tools to optimise energy use.

    A Basic Introduction to Interfacing for the Hardware Curious

    So you've got a Raspberry Pi or Beaglebone and now you want to connect some hardware to it. You know basically what you want to do but you're are feeling a little bit lost in the jargon. What is a GPIO pin? What is an SPI or I2C bus? What is a shift register? How do I get more outputs than I have pins? How do chose the resistor for an LED? How do I read the value of a push switch? What does 3.3V tolerant mean?

    This talk will look at the basics of hardware interfacing. It will describe the basics of the interfaces typical of embedded systems and how to approach programming them. It will discuss some very basic electronics theory that will be useful to the beginner hardware hacker. Finally it will give pointers as to where to look for further information.

    Melanie Rhianna Lewis started a life long love of electronics as a child when her Dad helped her make a "crystal" radio with an ear piece, a coil of wire, a diode and a radiator! At the same time the home computer revolution started and she would lust after the "build your own computers" advertised in the electronics magazines of the time. She never got one but did end up the proud owner of a BBC Micro. Melanie learnt everything she could about the machine and including assembler, operating systems, drivers, interrupt, and, thanks to the circuit diagram in the Advanced User Guide, digital electronics. After the BBC Micro came the Acorn Archimedes and so started a long relationship with ARM processors. In the 90s Melanie became interested in Linux and then developed one of the first ARM Linux distributions running on an Acorn RISC PC. The hobby became a job and Melanie currently works for an embedded device consultancy near Bradford where a lot of her work is still with ARM processors.
