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.

    Arduino Donations 2014: we are open to suggestions!

    via Arduino Blog

    donations2014

    Once again this year Arduino will make a donation ( for a total of 30,000 USD) to promote open source culture and innovation.
    This year, Arduino is also soliciting suggestions: througout 2014, we are asking our community to highlight the 10 organizations which would best benefit from Arduino support.

    Arduino is based on the contribution of many other open source projects and wants to support these and other initiatives sharing our approach and philosophy, through yearly donations.
    We thought it could be a great idea to involve the community for selecting the projects to support by suggesting us how they could benefit from Arduino donations.

    The Arduino community is invited to suggest beneficiaries – associations, foundations, institutions – according to one or more of the following cornerstones:
    - it brings innovations in the open electronic and making ecosystem
    - it’s an open source project
    - it facilitates the exchange of knowledge
    - it has an impact on open source ecosystem
    - it is a non commercial project

    The first call is open during May: anyone can fill this form to send a suggestion based on the cornerstones explained above by the 30th of May. At the end of June we’ll announce 5 finalists receiving a donation of $2000 each.

    The second call for submissions will happen during September.
    At Maker Faire Rome in October 2014, Arduino will announce the remaining 5 finalists receiving a donation of $2000 each.

    The final selection will be at the discretion of the Arduino team.

    Moreover, Arduino founders have already chosen their beneficiaries: Creative Commons, Free Software Foundation and Processing.

     

    Radio Pt.2 (Networking Literacy Project, Everyone has a radio in them)

    via OSHUG

    The thirty-third OSHUG meeting will be the second on the theme of radio, with talks on a bold vision for a project that aims to increase understanding of personal networking, and on a toolkit that lets you build your own physical Internet radio.

    The Networking Literacy Project

    "Beep-BEEP!" - Some of us will remember the distinctive click when throwing the power switch of a BBC Micro, and the immediate gratifying sounds it made. Thirty years ago, public awareness of personal computing was low, and civil society acted to raise literacy in anticipation of the coming boom. Today, computers are pervasive in everyday life, and their function is increasingly to deliver distributed computing applications. Indeed, we are on the cusp of another era of personal technological progress and growth, this time for personal networking. Understanding and literacy about this is low, while importance and opportunity are high. This talk will explore some of the learning opportunities, and how the technology community could contribute to eliminating the widespread functional illiteracy in this important area of technology.

    Martin Geddes is an authority on the future of the telecoms industry, ranging from emerging business models to new network technologies. He is a futurologist, writer, speaker, consultant, and technologist. Martin is currently writing a book, The Internet is Just a Prototype, on the future of distributed computing.

    Everyone has a radio in them, it turns out

    Inspired by the challenge of making a physical radio device that did anything interesting and web friendly, a small team within BBC R&D spent a few days building an Archers Avoider using off the shelf components and free software alongside BBC created custom services for controlling audio IP streams.

    "Radiodan" is now at v2.0 and consists of open source web-developer-friendly software designed to work on a Raspberry Pi, used for controlling audio streams, getting a device on a wifi network, and controlling buttons, dials and leds, plus a kit of parts, a case and some instructions.

    This talk will take a look at some of Radiodan's technology, in the context of our goal of making it something that anyone can start to build a radio with. It will also explore why it's important and interesting to widen the pool of people who can make radios, and how a new field for us has changed the way we work.

    Libby Miller is a producer and developer working in the BBC R&D Central Lab. She currently works on Radiodan, a project about cheap, rapid prototyping for radios. She also works on the VistaTV EU project on the use and visualisation of real-time IPTV statistics, and the MediaScape project, which is about developer-friendly standards for connected devices. Before that, she led the BBC's part of NoTube, including work on APIs to TV for second screens, resolution of broadcast metadata to web metadata, synchronised social experiences, and recommendations and serendipity.

    Note: Please aim to by 18:15 as the first talk will start at 18:30 prompt.

    Support Open Source Beehives and help promoting international bee recovery

    via Arduino Blog

    Open Source Beehive

    Recent declines in honey bee populations raised attention of many scientists and now makers started activating swell.

    The Open Source Beehives (OSBH) project is a collaborative response to the threat faced by Bee populations in industrialised nations around the world.
    They’ve just launched a campaign on Indiegogo and are waiting for your contribution.

    The campaign will help to build new sensors to understand the behaviour of the bees and the pollutants that are killing them. Also the production of the hives relies on the Fab Lab Network, which makes it able to be produced anywhere in the world. The project is proudly powered by the Arduino At Heart Smart Citizen Kit.

    Jonathan Minchin, the bee-man in the lab ;) , told us:

    The development team is made up of makers, technologists, entomologists and is being led by a wide ranging community of beekeepers. The OSBH team came together in 2013 from the Fab Lab Barcelona, OKNO in Brussels and the Open Tech Collaborative in Denver with the shared objective of designing hives that can support Bee colonies in a sustainable way. To monitor and track the health and behaviour of a colony as it develops and to engage an active and diverse community to respond to the threats faced by Bees.

    Work began to design our Internet-connected beehives and to put them into backyards everywhere. The aim is to grow a citizen-led beehive network that both strengthens bee populations and generates insightful hive data, ultimately we want to help discover what is causing Colony Collapse Disorder (CCD). The Smart Citizen platform and (SCK) sensor kit with Arduino at heart provides a perfect fit with the aims of the project in that it allows us to quickly and efficiently develop a powerful and specialised sensor shield adapted for use within a Beehive. The data we produce can also be published openly to the Smart Citizen online platform and shared with the community.

    Open source beehive

    The data from the hives will help beekeepers and scientists monitor the temperature, humidity and relevant sound frequencies coming from within the hives in a non-intrusive way. This data helps them to understand what the colony is doing and how it reacts to environmental changes. We are also working with sensors that can measure the weight of the hive and monitor air born pollutants that might affect the bees. The data collected from each hive is published together with geolocations, allowing for a further comparison and analysis between the hives.

    These sensor enhanced hive designs as well as the electronic schematics are being published openly and can be downloaded and made locally at a Fab Labs or any other maker space. The hives along with different options to support the project can be ordered through our current crowdfunding campaign on Indiegogo.

    Now watch the video to look at some visual details and meet the other collaborators:

     

    Embedded Scripting (Lua, Espruino, Micro Python)

    via OSHUG

    The thirty-second OSHUG meeting will take a look at the use of scripting languages with deeply embedded computing platforms, which have much more constrained resources than the platforms which were originally targeted by the languages.

    Programming a microcontroller with Lua

    eLua is a full version of the Lua programming language for microcontrollers, running on bare metal. Lua provides a modern high level dynamicaly typed language, with first class functions, coroutines and an API for interacting with C code, and yet which is very small and can run in a memory constrained environment. This talk will cover the Lua language and microcontroller environment, and show it running on-off-the-shelf ARM Cortex boards as well as the Mizar32, an open hardware design built especially for eLua.

    Justin Cormack is a software developer based in London. He previously worked at a startup that built LED displays and retains a fondness for hardware. He organizes the London Lua User Group, which hosts talks on the Lua programming language.

    Bringing JavaScript to Microcontrollers

    This talk will discuss the benefits and challenges of running a modern scripting language on microcontrollers with extremely limited resources. In particular we will take a look at the Espruino JavaScript interpreter and how it addresses these challenges and manages to run in less than 8kB of RAM.

    Gordon Williams has developed software for companies such as Altera, Nokia, Microsoft and Lloyds Register, but has been working on the Espruino JavaScript interpreter for the last 18 months. In his free time he enjoys making things - from little gadgets to whole cars.

    Micro Python — Python for microcontrollers

    Microcontrollers have recently become powerful enough to host high-level scripting languages and run meaningful programs written in them. In this talk we will explore the software and hardware of the Micro Python project, an open source implementation of Python 3 which aims to be as compatible as possible with CPython, whilst still fitting within the RAM and ROM constraints of a microcontroller. Many tricks are employed to put as much as possible within ROM, and to use the least RAM and minimal heap allocations as is feasible. The project was successfully funded via a Kickstarter campaign at the end of 2013, and the hardware is currently being manufactured at Jaltek Systems UK.

    Damien George is a theoretical physicist who likes to write compilers and build robots in his spare time.

    Note: Please aim to by 18:15 as the first talk will start at 18:30 prompt.

    Privacy and Security (Security protocols in constrained environments, RFIDler, Indie Phone)

    via OSHUG

    The thirty-first OSHUG meeting is dedicated to privacy and security, with talks on implementing security protocols in constrained environments, an SDR RFID reader/writer/emulator, and a new initiative that will use design thinking and open source to create a truly empowering mobile phone.

    Security protocols in constrained environments

    Implementation of security protocols such as TLS, SSH or IPsec come with a memory and compute overhead. Whilst this has become negligible in full scale environments it's still a real issue for hobbyist and embedded developers. This presentation will look at the sources of the overheads, what can be done to minimise them, and what sort of hardware platforms can be made to absorb them. The benefits and potential pitfalls of hardware specific implementations will also be examined.

    Chris Swan is CTO at CohesiveFT where he helps build secure cloud based networks. He's previously been a security guy at large Swiss banks, and before that was a Weapon Engineering Officer in the Royal Navy. Chris has tinkered with electronics since pre-school, and these days has a desk littered with various dev boards and projects.

    RFIDler: A Software Defined RFID Reader/Writer/Emulator

    Software Defined Radio has been quietly revolutionising the world of RF. However, the same revolution has not yet taken place in RFID. The proliferation of RFID/NFC devices means that it is unlikely that you will not interact with one such device or another on a daily basis. Whether it’s your car key, door entry card, transport card, contactless credit card, passport, etc. you almost certainly have one in your pocket right now!

    RFIDler is a new project, created by Aperture Labs, designed to bring the world of Software Defined Radio into the RFID spectrum. We have created a small, open source, cheap to build platform that allows any suitably powerful microprocessor access to the raw data created by the over-the-air conversation between tag and reader coil. The device can also act as a standalone ‘hacking’ platform for RFID manipulation/examination. The rest is up to you!

    Adam “Major Malfunction” Laurie is a security consultant working in the field of electronic communications, and a Director of Aperture Labs Ltd., who specialise in reverse engineering of secure systems. He started in the computer industry in the late Seventies, and quickly became interested in the underlying network and data protocols.

    During this period, he successfully disproved the industry lie that music CDs could not be read by computers, and wrote the world’s first CD ripper, ‘CDGRAB’. He was also involved various early open source projects, including ‘Apache-SSL’ which went on to become the de-facto standard secure web server. Since the late Nineties he has focused his attention on security, and has been the author of various papers exposing flaws in Internet services and/or software, as well as pioneering the concept of re-using military data centres (housed in underground nuclear bunkers) as secure hosting facilities.

    Andy Ritchie has been working in the computer and technology industry for over 20 years for major industry players such as ICL, Informix, British Airways and Motorola. Founding his first company, Point 4 Consulting at the age of 25, he built it into a multi-million pound technology design consultancy. Point 4 provided critical back end technology and management for major web sites such as The Electronic Telegraph, MTV, United Airlines, Interflora, Credit Suisse,BT, Littlewoods and Sony. Following Point 4 he went on to found Ablaise, a company that manages the considerable intellectual property generated by Point 4, and Aperture Labs. In his spare time he manages the worlds largest and longest running security conference, Defcon. Andy's research focuses on access control systems, biometric devices and embedded systems security, and he has spoken and trained at information security conferences in Europe and the US publicly and for private and governmental audiences. He is responsible for identifying major vulnerabilities in various access control and biometric systems, and has a passion for creating devices that emulate access control tokens either electronic physical or biometric. Andy has been responsible both directly and indirectly for changing access control guidelines for several western governments. Andy is currently a director of Aperture Labs Ltd, a company that specialises in reverse engineering and security evaluations of embedded systems.

    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.

    Fueling the Hardware Revolution with Tindie

    via Arduino Blog

    Tindie

    Some people call it the “Etsy for hardware”, some other “the indie marketplace for open source hardware”, even if being open is not a requirement. Tindie’s mission consists of connecting the world’s small, hardware businesses with customers all over the world and today starts a cool initiative called Open Designs and Kickbacks. When sellers create a new product, they will be able to select a project the product is a derivative from, and enter the % of sales that will go to the open hardware project.

    “Businesses can manufacture the open design as is, or create products derived from it. Those sellers can then kickback a portion of their sales back to the designer. Tindie will handle the disbursement of funds so it’s absolutely painless. For designers, there are no fees, no hosting costs, just a simple way to reap the benefits of their hard work”

    Some weeks ago Arduino announced in a blogpost about donating every year to projects which are part of the open source ecosystem because we are grateful to these efforts and want to support them and now we are happy to announce of being Tindie’s first partner in the Open Designs’ initiative.   Businesses that have built on top of Arduino boards can now send a portion of their sales back to Arduino, and help us further growing our efforts in supporting the open source community. Take a look at the products derived from Arduino.

    For more info and insights, take a look at the Tindie’s website.

    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.

    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.

    A Neonatal Baby Monitor goes open source and collaborative in Kenya

    via Arduino Blog

    OpenBabyMonitorTeam

    On the 11th of August a team composed by researchers from FabLab Pisa and University of Pisa’s Center for Bioengineering and Robotics “E.Piaggio” will start a great adventure with a Summer School on the project called OS4BME (Open Source for Biomedical Engineering).

    The aim of the project is to bring the DIY&Makers approach in the developing of simple, low cost/high impact biomedical devices, precisely, in this particular case, a neonatal Baby Monitor.

    The course will take place at Kenyatta University (Nairobi) and it will involve setting up a 3D printing system, developing a neonatal monitoring device, using open source, electronics based on the Arduino platform and powered by solar panels.

    Participants will play an active role in the identification of components, design, assembling and testing of the device and in the discussion of regulatory issues in its development. Close attention will also be paid to safety, ergonomic aspects and regulatory  standards for biomedical devices.

    The medical device industry in Africa is largely absent and there is an over reliance on foreign companies to repair and design biomedical instrumentation and resolve technical problems … More importantly, at present there are no specific engines or platforms focused on the sharing of biomedical instrumentation and devices. This is because, by their very nature, biomedical devices possess stringent performance requirements to comply with regulatory standards to ensure patient safety.

    OS4BME is a project created by Prof. Arti Ahluwalia (Univ. Pisa), Daniele Mazzei and Carmelo De Maria (both from Fablab Pisa but also post-doc researchers at Centro E.Piaggio). The summer school is an initiative organized by a consortium of nine African universities with the objective of creating a sustainable health-care system, developing a network of academic excellence for Biomedical Engineering in Africa with the support of the ‘United Nations Economic Commission for Africa (UNECA).

     Arduino is supporting the project and  we sent to the team a bunch of Arduino UNO boards, Wi-Fi and GSM Shields to be used during the course and then will be donated to the Kenyatta University and Fablab Nairobi.

    Arduino Package

    In the next week  we’ll keep in touch with the team and receive updates directly from the summer school. Stay Tuned on this blog and on the work in progress of their WIKI!

    Boards (Beautifully Functional Circuits, Little Printer)

    via OSHUG

    At the twenty-seventh meeting there will be a talk on designing printed circuit boards that are aesthetically pleasing as well as functional, and a talk on the design and manufacture of the Little Printer, and the upcoming BERG Cloud dev board.

    Beautifully Functional Circuits

    Circuit design is typically thought of as block-based and purely functional; it doesn't necessarily have to be. Our inherent creativity as engineers has been dampened by unimaginative and limiting design tools, that have forced us to "forget" that functional circuits can, and should, be beautiful too. This talk will explore these limitations and how we could do better.

    Saar Drimer is an experienced hardware engineer. In the past few years he's been developing tools for effective and efficient hardware design.

    Little Printer

    In 2012 the design and product company BERG launched Little Printer, their internet-connected thermal printer that prints its own face. It was the first consumer product that BERG had made, and went on to be nominated for the 2013 Designs of the Year by the Design Museum.

    In this talk we will explore the project's evolution, from prototype to mass produced product. The talk will cover the way BERG's design process works, going to China to organise plastic injection moulding, passing certification and EMC, and many other practical aspects of making and selling consumer products that connect online.

    The talk will also cover a technical overview of the whole stack that brings Little Printer to life, the extraction and evolution of the underlying BERG Cloud platform, and the forthcoming developer kits that open up the platform to anybody.

    Nick Ludlam is CTO at BERG, and is responsible for the collective software development, from the embedded code running inside Little Printer, the Ruby/Rails-based cloud architecture, and the use of Amazon Web Services to scale.

    Andy Huntington is Hardware Producer & Designer at BERG and is responsible for all of BERG's physical hardware, from the electronics and PCBs to the industrial design and manufacturing of Little Printer itself. He has a background in music and moved through software into hardware following an Interaction Design MA at the Royal College of Art.

    Note: Please aim to arrive for 18:00 - 18:20 as the event will start at 18:30 prompt.
