The MagPi issue 26 – out now!

via Raspberry Pi

August’s MagPi, the magazine for the Raspberry Pi community written by the Raspberry Pi community, is out now. As always, it covers the whole spectrum of Pi users, from absolute beginners to people looking for challenges; and as always, it’s a free download.

MagPi issue 26

This month you’ll find a continuation of the robot series that kicked off last month, adding voice control, facial recognition and speech to your home-made friend. There’s a fun persistence of vision (POV) magic wand project, an in-depth introduction to the new Model B+, and a great example of a dynamic art application for total beginners.

Our favourite project this month is Mashberry, a home brewery project which you can control using a TV remote. There’s lots more too: click on the image above (or here) to read the latest issue.

The MagPi team are always looking for volunteers to help produce the magazine: there’s a lot involved in getting a monthly publication ready beyond the writing and proofing. They’re always looking for writers and proofreaders, but if you’re interested in the production side of things in particular – that’s layout, typesetting, graphical work and testing – they’d especially love you to get in touch. If you can help, email editor@themagpi.com, or comment on their Facebook
page.

MagPi issue 25 – out now!

via Raspberry Pi

For your weekend reading pleasure, here’s issue 25 of the MagPi! Published just yesterday, the latest issue of everyone’s favourite free, monthly, community-produced Raspberry Pi magazine is as full of fantastic stuff as ever.

The MagPi issue25

The cover story is one that’ll definitely get some attention in our house this weekend: it’s a full Python simulation of the Pocket Enigma Cipher Machine, a cleverly devised toy that demonstrates some of the principles of a real Enigma machine like the one many of you will recognise in the cover photo. Used by the German armed forces during World War II to encipher messages, these used rotating disks to achieve a sophisticated substitution cipher; the Pocket machine, and its Python simulation, use two disks to arrive at a fun, if not exactly unbreakable, cipher.

We’re delighted to see an article by Andrew Suttle, the MagPi’s youngest guest writer so far. Andrew reviews the Fish Dish, an easy-to-build add-on board aimed at beginners, which he has tested with ScratchGPIO and Python. Also aimed at beginners is a new series on learning BASIC, which opens this issue with the kind of background that has most of Pi Towers sighing wistfully and exchanging anecdotes about our childhoods.

There’s the second half of a two-part article on understanding networks and network analysis tools, an introduction to electronic measurement with Raspberry Pi and BitScope Micro, a background piece by one of the creators of the Navio autopilot shield which the many backers of its successful Indiegogo campaign will be eager to read, and — another personal favourite — a tutorial on building an iPad/iPhone control panel for Raspberry Pi with RasPiConnect, taking the wonderful MouseAir deluxe automated cat toy as its example.

As usual, there’s so much here that I can’t mention even half of the articles, tutorials and reviews you’ll find here for beginners, advanced users and everyone in between. Download your copy now!

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.

Ben Ward is founder of Love Hz, promoting the use of white space spectrum for open innovation in the Internet of Things. A survivor of the dotcom bubble, subsea bandwidth glut and the UK broadband wars, he's still surprisingly optimistic about the future.

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.

Simon Cook leads Embecosm's work on LLVM and is author of the standard guide to the LLVM assembler. He is also an expert on low-energy compilation and is lead engineer on the MAGEEC project. Simon holds a double first class honors degree in Computer Science and Electronics from Bristol University.

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.

Workshop notes: Bring along a laptop and, if you like, an Arduino or Raspberry Pi.

Introduction to Bus Pirate

The Bus Pirate is a universal open source hardware device that can be used to communicate using various buses, such as SPI, I2C, UART and JTAG, with various devices. The Bus Pirate is, per the designers, intended to "Eliminate a ton of early prototyping effort with new or unknown chips."

This tutorial will introduce the Bus Pirate. Describe how to configure it and install the software required to use it. It will then look at some basic interfacing to devices via SPI and I2C. It will work through how you can 'sniff' buses. Finally it will look at use the Bus Pirate as a simple frequency measurement and generator device.

Run by: Melanie Rhianna Lewis.

Workshop notes: bring along a laptop (Bus Pirate is supported under Windows, Linux and OSX) and, if you can, some hardware to debug. There will be a limited number of Bus Pirates available, but if you have one please bring it along.

The real world works concurrently and so can you

This workshop will take you through the basics of embedded concurrent programming using an XMOS multi-core startKIT. We will cover basic parallel processing extensions to C (XC) using tasks, interfaces, timers and ports. We will also get some insight into our running code using xSCOPE, a real-time debugging system built in to the XMOS tools. In addition we will use software modules to drop in rich functionality from the open source xCORE libraries.

Run by: Alan Wood.

Workshop notes: bring along a laptop and any devices you would like to interface.

Design a PCB Shrimp and have it fabricated

The Shrimp is a super low cost Arduino clone. It makes an excellent teaching resource, and is usually delivered as a 'breaded shrimp' - using a breadboard. For hackers, it's a great way to knock up a quick, cheap microcontroller circuit.

In this workshop we'll make a PCB version of the shrimp — a more robust and Arduino shield compatible version — and you will be guided through the process of drawing the schematic, laying out the PCB and optionally placing an order with OSHPark for your very own PCB shrimp.

Participants will be working in pairs. Boards will cost about £6 each. Kits of components can conveniently be ordered from shrimping.it for £4.

    We’re biased, but our favourite article this month is the interview with our very own Carrie Anne Philbin about Picademy, our free teacher training courses, where she talks a lot about the Raspberry Pi Foundation’s approach to education. And our hearts went pitter-patter when we saw the Wolfram Language-powered spectrophotometer from Robert J LeSuer, which can be used to calibrate colours: in this instance Robert is using it to make sure his watermelon punch is precisely the correct shade of red. There’s the final instalment in Michael Petersen’s Weather Balloon series, a project from Daniel Pelikan which turns your Raspberry Pi into an oscilloscope, and much more.

    The MagPi is a free download: the volunteers on the project donate their time and skill every month for free, and we are very grateful to them. If you’d like a printed magazine, we’re selling the MagPi’s Kickstarted binders of the first nineteen issues in the Swag Store: get them while they’re hot!

    DIY IWBs for Officine Arduino 2nd Birthday

    via Arduino Blog

    Officine Arduino Party

    Arduino has a little (yet effective) bit in Turin, and that’s Officine Arduino. We opened this place two years ago to offer a shelter to the Arduinians in northern Italy and host a makerspace, for their creations. We witnessed (and joined) the foundation of the Torino Fablab, an association offering the very same machines to anybody interested about the maker movement in Turin. On top of that, the all ardu-maker-fab-co-creative space is hosted in Toolbox Coworking.

    It’s tough to weight all the efforts and failures and successes we reached in these two years. We’ve seen the birth of Verkstad Arduino, the Swedish Arduino Office which is sharing the same principles we’ve been looking for in conceiving this place: mixing the company approach and the horizontal, informal one of makerspaces and coworking spaces (aka collaboration spaces).

    I love the way Arduino Team dealt with the growing of the project: create different little places rather than having a huge one.

    Wonderful Lasercut

    On top of that, Officine Arduino wouldn’t have been so without the help of Smartprojects (one of the main producers of Arduino). A selfless and generous helping hand towards us and towards italian makers in general. They lended us their lasercutter for 2 years, now that we are setted up they are going to lend the very same lasercut to another newborn fablab! This is the picture I took when I broght the lasercut back last week.

    Interactive Whiteboard

    Last year we celebrated our birthday with Josef Prusa and the building of ten reprap 3d printers. This year we want to dedicate our birthday to education, so we are going to host and build Interactive digital writeboards during the week end, following the Wiildos opensource project, with Pietro Pilolli (project host with Matteo Ruffoni e Massimo Bosetti).

    Friday is important for yet another reason: Toolbox is going to host the press conference of the newborn italian maker association, inwhich Massimo plays the role of president: Make in Italy Cdb Onlus. If you are a journalist or maker you can enroll here to join the press conference.

    tl;dr: we are partying this upcoming friday, if you pass by let us knowFB Event. Interested in building your own Interactive Open Source Digital Writeboard? Join the Make In Italy Cdb Onlus Press conference here.

     

    Making is Best When it’s Done Together

    via Arduino Blog

    makingtogether_massimo

    (originally posted on Makezine)

     

    This month I’d like to talk about the idea of making together and what it means for Arduino. The whole idea of being a maker involves concepts of collaboration, community, and working with other people. It’s very hard to be a maker and be by yourself locked in a room or even in a lab. It’s really something that involves a lot of collaborations at different levels.

    Many people today know what Arduino is, but very few know about two projects I did before Arduino. They were my first attempts to solve the problems my students had in prototyping with electronics. I consider them “creative failures.” As makers, we welcome failure as a way to understand how to do it better the next time.

    Those initial projects I prototyped were not working so well because the technology was not really good but mostly because when I developed these things I did them by myself. I didn’t involve other people and I was very inefficient in trying to get them to work properly. They solved a number of problems my students had, but they didn’t really get a lot of momentum.

    Ten years ago I started teaching at Interaction Design Institute in Ivrea (unfortunately it doesn’t exist anymore) where the Olivetti company used to be. In the picture below you can see their building and it’s not hard to notice it was created with a “design” approach. Olivetti was one of the first companies in the world to really apply design to everything: from their typewriters, to their buildings and to their posters, etc. Mr. Olivetti had that idea factories should have paintings on the walls because workers should be surrounded by beauty and knowledge. It was part of a bigger approach putting people at the center. It was in this context at the institute where we developed a number of projects before we came out with Arduino in the shape you know it now.

    makingtogether_ivrea

    If you peel back the surface, underneath Arduino project you can find a lot of collaboration. On one side you can see a selection of pretty amazing open source software contributing to what Arduino has become. I’m talking about GCC, processing, wiring, AVR, and all the other contributions from the community. On the other side, I started to involve specific people.

    I met David Cuartielles when he was researching in Ivrea and we started to talk about things we wanted to see in the platform to help our students getting started with electronics. Slowly we also got in touch with other people: Tom Igoe, a professor at ITP in New York with great experience; David Mellis, an amazing software developer who joined Ivrea from MIT; and Gianluca Martino, an electronics engineer who knows every company involved in electronics in the area. He’s now taking care of the manufacturing.

    I gathered all these people one-by-one because we wanted to make an open project based on collaboration. All the founders brought their own experience into Arduino and later what became really important was the Arduino community. At the moment there is a community much larger than number of official Arduino boards we have sold. There are more than 180,000 people subscribed to the forum and more than 4 million monthly page views to the website with visitors spending about five minutes on each visit.

    Arduino was born out of different contributions and it taught us to follow this path with most of our products. We started collaborating with other people and companies of the open source community, extending our role as makers into ideas and projects becoming products. Recently, we told you the story of the Arduino robot and an example of collaboration.

    For example, some years ago, with Adafruit we developed the Arduino Micro packing all of the power of the Arduino Leonardo in a smaller board. We met with Limor and Phil sharing a lot of ideas and more projects are coming up in the next months.

    At some point we also worked with Telefonica, a global mobile operator, to make the Arduino Gsm Shield. The technology of the shield is basic but we worked really hard to develop the API to use the module very easily. What’s important about these collaborations is not the technology but other things like lowering the barriers to access a sim card and allowing people to activate it very simply, just with a credit card. The value we created was about opening up a collaboration and making a big company like Telefonica aware of the impact of a product like this in the maker community.

    A similar thing, but with a smaller company, happened for Arduino Yún. DogHunter, based in Taiwan, designed the board together with us. The factory we usually work with in Europe didn’t have the experience to work with wi-fi technology so we teamed up with a factory in Taiwan which had an experience with millions of access points. Arduino Yún became the first official board made in Asia.

    In the first half of 2014 we are going to release the Arduino TRE. It’s a combination of a Beaglebone and an Arduino plus a number of things designed to make it very convenient for people to get started. We worked with Texas Instruments and especially Beagleboard, which shares with us a series of commitments to open source hardware and similar goals and ideas, like the desire for simplicity and ease of use.

    Once again we realized how easier it is to find someone who can give you a cheaper piece of hardware, but in the long run, even if it’s harder to find someone who shares the same set of values, it’s well worth it.

    We believe in the open source movement and everyone should be really aware that it can develop successfully if everyone takes from it, but especially if people and companies contribute back. That’s why it’s important to highlight who creates a positive loop and nurture knowledge sharing and collaboration.

    Even if there is the perception the maker movement is much more U.S.-centric, with a lot of visibility for American makers, events, and companies, we believed that we could do something to improve the relations among the movement here in Europe and activate more positive loops.

    We realized that one of the issues was about language. Many European makers are very active in their local community, but they don’t Speak English. That’s why we decided to invest time and resources to create an European Maker Faire in Rome, inviting people from all over the continent. It was not easy to organize it, but I can say that it was an incredible success with more than 35,000 participants. It proved that in Europe people want to get together, know each other and cross the boundaries of the over 27 countries with different languages.

    Maker Faire is not an event that has to do strictly with people making hardware. For me it’s much more important because it opens up channels of communication between makers and the concept of making together. We are happy to show what makers can do and how they could collaborate toward a future of great open source projects and, later, bringing benefit to communities around the world.

    Concrete Batch Plant using Arduino and LIFA in Bangladesh

    via Arduino Blog

    concrete plant

    Arduino user Geotechbd wrote us from Bangladesh to share his experience:

    Our company here in Bangladesh owns a quite old concrete batch plant, which had full manual control requiring an operator to control 14+ switched and observe 3 mechanical scales (dial gauges). I was successful to upgrade this plant to an automated unit requiring minimal operator input using custom made Arduino Uno compatible board and LIFA. Wiring is still messy which I shall take care in the near future.

    concrete plant

    On his blog he then details a list of tools, components, and at the end of the post, thanks all the people and communities who supported him in this challenge:

    My gratitude goes to my lovely wife for keeping me sane and my brother for arranging for ICs not available locally. My sincerest thanks goes to the Arduino community for helping me to remedy EMI problem and LIFA community for I2C communication troubleshooting. I must thank the developers of Arduino/LIFA/Fritzing for making electronics more accessible to the general masses.

    My electronics and Arduino knowledge was gathered from websites as tronixstuff.com / jeremyblum.com / arduino.cc, so thanks to excellent contributors of these sites. I had support personnel (a very patient electrician and a plant operator) here who helped me with wiring high voltage lines, and plant operational knowledge; thus, they also deserve thanks.

    It’s cool to see how open source creates collaborations among people all over the world!

    Making it in China

    via Arduino Blog

    (originally posted on Makezine)

    Right after the overwhelming experience of Maker Faire Rome I left Europe for a week a quick tour in China. There are a lot of cool things happening there. I’d been to China twice before for a very short time so this time I wanted to spend a few days to meet with people and take part in some cool events going on in Shanghai and Shenzhen. I accepted an invitation to give a talk about Arduino at the School of Design of Hong Kong Polytechnic University and while I was there, William Liang (adjunt assistant professor at the same university) took me to visit the local community at the Dim Sum Lab hackerspace.

    Dim sum is a delicious, Hong Kong speciality composed of a myriad of different, bite-sized delights. Similarly, the DimSum Lab hosts different types of communities with various interests, from coders to makers.

    I then flew to Shenzhen to meet with the people at SeedStudio who took me around the city to discover the different opportunities this city offers. Makers are closer to the manufacturers here and have easier access to new components and parts. Clearly there is an advantage and certain makers, if they get organized, can jump quickly from a small idea to large scale manufacturing for a much lower cost.

    This happens because they are not only close to manufacturers, but closer to the supply chain as 90 percent of electronic parts are made in China and you can basically assemble a device very quickly because of easy access to parts. Recently, Seeds Studio published the Maker Map of Shenzhen which looks a bit like the celeb’s house map you get in Los Angeles, but instead of getting information on where famous actors live, you can easily find out where suppliers, manufacturers and hackerspaces are.

    maker map

    There are also lots of projects based on Arduino. We realized more than 90 percent of the boards people use are fake, not even Arduino clones, but fakes. We discussed this topic with SeedStudio which has always been very respectful of the Arduino project and of the use of our trademark. It’s understandable, in a way, that an Arduino made in Europe tends to be quite expensive for most of the people in China. We know that the interest in Arduino is very high and we are working on how to provide official Arduino boards in China.

    As we often said, it’s not only about making boards and selling them. It’s about creating all the official documentation in Chinese, having an official forum and social media presence, and making videos and sharing them outside of YouTube (inaccessible for many Chinese people). We clearly need to change the way we do things to be able to interact with the Chinese community. It’s going to take a bit than just focusing on providing accessible boards.

    Later, when we visited the local hackerspace in Shenzhen called Chaihuo, some of the people I met there had just come back from Maker Faire Rome. They showed me all the pictures they took and it was amazing how they reported back to their peers the experiences they had in Italy and the projects they discovered during the event. During the Q&A session we had, they asked me a lot of really detailed questions and Eric Pan, from Seeds Studio, did a great job in translating my answers.

    Next stop was Shanghai where I gave a talk at the Sino-Finnish Centre at College of Design and Innovation at Tongji University. I visited the community of the XinCheJian hackerspace and then participated in HackedMatter, a whole day focused on rethinking manufacturing from the point of view of science fiction narratives and exploring “how the professionalizing of maker culture is developing increasingly intimate relations with the small-scale factory owners and micro-entrepreneurs that make up China’s core of hardware manufacturing”.  The event was organized by Silvia Lindter in conjunction with the Shanghai Maker Carnival.

    Speaking at HackedMatter in Shanghai.  Photo by Silvia Lindtner.

    During Hacked Matter I gave a talk on the topic of collaboration, a concept at the heart of the Arduino approach, highlighting the idea that innovation is not purely about technology, but more on creating the right collaborations with the right people.

    It was interesting to note that the maker community in Shanghai is pretty diverse and composed not only by locals as there are a lot of people coming originally from outside China who moved there. At the Maker Carnival I discovered many high quality projects and realized some differences with the community in Shenzhen. It was also interesting to understand how Chinese culture works and how Arduino can create channels to communicate within that culture.

    Open hardware companies from around the world could clearly benefit from a trip to China especially if they can find someone local to work with, tapping into the local community to go beyond language barriers. There’s a lot of very talented people over there able to deal with complicated projects. At the various hackerspaces I visited I received interesting questions and I was lucky enough to have someone translating otherwise I’d never met these smart people.

    Speed (overclocking, souped-up BBC Micro, compiler optimisation)

    via OSHUG

    The thirtieth OSHUG meeting is dedicated to the quest for computing speed. It will feature talks on a hardware design to aid overclocking, retrofitting a 30+ year old microcomputer with modern processors, and compiler optimisation.

    Fast and Furious: Overclocking chips for fun and profit

    Due to the variance in silicon manufacturing technologies, integrated circuits used in everyday designs are usually spec'ed at lower speeds than their actual capabilities. It is, therefore, not unlikely for chips to run faster than their advertised speeds, sometimes at significant margins with a little push. The umbrella term used for this practice is overclocking and it encapsulates a variety of techniques from simply increasing the clock speed to employing elaborate systems with liquid nitrogen cooling.

    This talk will provide an overview of overclocking and overvolting techniques — investigating the effects of forcing chips to run faster on the silicon level — and present vftweak: an open source hardware design that aims to simplify experimenting with circuits by providing a programmable interface and monitoring tools.

    Omer Kilic works on Erlang Embedded, a Knowledge Transfer Partnership project in collaboration with University of Kent and Erlang Solutions. The aim of this project is to bring the benefits of concurrent systems development using Erlang to the field of embedded systems; through investigation, analysis, software development and evaluation.

    Before joining Erlang Solutions, Omer was a research student in the Embedded Systems Lab at the University of Kent, working on a reconfigurable heterogeneous computing framework.

    Omer likes tiny computers, things that 'just work' and real beer.

    Souping up the BBC Micro

    This talk will introduce a selection of projects which allow modern processors to be used with a 30+ year old BBC Micro, before exploring in more detail the speaker's own open hardware contribution to the options available.

    Jason Flynn creates open electronics designs for the amateur radio and retro computing. His main areas of interest are digital TV, microwave, satellite and most things related to Acorn and ARM. He previously held a post on the RSGB Data Communications Committee, is an honorary member of SSETI, has been committee of Martlesham Radio Society for 7 years, and is presently involved in setting up a hackspace in Ipswich.

    How compiler optimisation helps you get the best out of your hardware

    This talk will give a high-level overview of compiler optimisation, covering general approaches used in both local and global optimisation, and also taking a look at the technique of superoptimization. The talk will conclude by looking at some of the 200+ optimisation passes used in GCC.

    The talk will be given by Jeremy Bennett, and he will be joined by Joern Rennecke and Simon Cook, who will take questions about optimisation in the compilers on which they are involved.

    Dr Jeremy Bennett is founder of Embecosm and an expert on debugging and silicon chip modeling. A former academic, Jeremy holds a MA and PhD from Cambridge University and is a Chartered Engineer, Chartered Information Technology Professional and Fellow of the Royal Society of Arts. He is the author of the standard textbook, "Introduction to Compiling Techniques" (McGraw-Hill 1990, 1996, 2003).

    Simon Cook leads Embecosm's work on LLVM and is author of the standard guide to the LLVM assembler. He is also an expert on low-energy compilation, being lead engineer on the MAGEEC project. Simon holds a double first class honors degree in Computer Science and Electronics from Bristol University.

    Jörn Rennecke is an expert on compiler back-end optimization and also leads Embecosm's work on GCC. Over 18 years he has become one of the all-time largest contributors to the compiler. During 2006-9, Jörn was a major contributor to the EU-funded MILEPOST project, which developed the first machine learning compiler optimization framework. He is currently maintainer for GCC for the Epiphany and Synopsys ARC architectures and a major contributor to GCC for Atmel AVR.

    Production by the Proletariat (RepRap, TVRRUG)

    via OSHUG

    For the twenty-ninth meeting we will be joining forces with the BCS Open Source Specialist Group, to host talks from the creator of RepRap, Adrian Bowyer, and Alan Wood of Thames Valley RepRapUser Group.

    The Ownership of the Means of Production by the Proletariat

    Look at your computer setup. Imagine you hooked up a 3D printer. Instead of printing on bits of paper this 3D printer makes real, robust, mechanical parts. To give you an idea of how robust, think Lego bricks and you’re in the right area. You could make lots of useful stuff, but interestingly you could also make lots of the parts to make another 3D printer. That would be a machine that could copy itself.

    This talk will be about RepRap – the Replicating Rapid-prototyper. This 3D printer builds the component up in layers of plastic. This technology already existed before RepRap, but the cheapest proprietary machine then would have set you back £15,000. And it wasn’t even designed so that it could make itself. So what the RepRap team have done is to develop and to give away the designs for a much cheaper machine with the novel capability of being able to self-copy (material costs are about £300). That way it’s accessible to small communities in the developing world as well as individuals in the developed world. The RepRap machine is being distributed entirely free to everyone using open-source – so, if you have one, you can make another and give it to a friend…

    Adrian Bowyer holds a first degree and a PhD in engineering from Imperial College. He was an academic at the University of Bath for 35 years. He retired in 2012 to help to run the company RepRap Professional Ltd.

    Adrian's areas of research are geometric modelling and geometric computing in general (he is one of the authors of the Bowyer-Watson algorithm for Voronoi diagrams), the application of computers to manufacturing, and biomimetics. In 2004 he created RepRap – humanity’s first self-replicating general-purpose manufacturing machine.

    Experiences from the Thames Valley RepRap User Group

    Thames Valley RepRap User Group (TVRRUG) was set up to provide support to those who wanted to build their own RepRap 3D printer, and to exchange information and ideas between those who had already successfully completed builds.

    TVRRUG has now organised three group build rounds, sourcing and printing parts, and resulting in many working printers. Along the way the group has produced extensive documentation, and designed its own electronics and a variant of the Prusa Mendel design.

    Alan Wood originally trained in systems engineering, and got lost in software engineering and F/OSS for a decade, before returning back to his hardware roots via the open source hardware and makers movement that has gathered momentum in recent years.

    Note: Please aim to arrive for 17:30 - 18:20 as the first talk will start at 18:30 prompt.

    Take the 2013 Open Source Hardware Community Survey.

    via Arduino Blog

    Catarina Mota and I put together an updated version of the annual Open Source Hardware Community Survey for the Open-Source Hardware Association (OSHWA). Here’s a summary:

    Our goal is to arrive at a better understanding of who we are as a community, why and how we use/make open-source hardware, and how our practices and numbers are changing over time. For this purpose, we are asking all those who use and/or develop open-source hardware to please respond. The aggregate results will be made publicly available after the survey closes. By publishing your responses, we hope to provide the public with insights into the practices and experiences of the people involved in open-source hardware.

    Please help us understand the open-source hardware community by taking the survey.

    You can also check out last year’s results.

    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.

    White Space — Connect all the Things!

    White space spectrum may hold the key for wide-area sensor networks. Find out how we can all enable the Internet of Things with this new technology.

    Ben Ward is founder of Love Hz, promoting the use of white space spectrum for open innovation in the Internet of Things. A survivor of the dotcom bubble, subsea bandwidth glut and the UK broadband wars, he's still surprisingly optimistic about the future.

    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. Paul graduated in electronics and was responsible for hardware and software product development and customer services in several product and service start-ups, switching to consulting in 2000.

    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.
