by Andrew Back 05 Jan '15

05 Jan '15

Hello, Registration is now open for the first meeting of 2015, which will be hosted at Sheffield Hallam University and in conjunction with the BCS OSSG. In February we will return to hosting meetings at the BCS offices in Covent Garden. However, should anyone have any suggestions for hosting a special meeting elsewhere in the country, please get in touch! Cheers, Andrew // Event #37 — Open Source in Business 22nd January 2015, 17:30 - 20:30 at Owen Lecture Theatre, 1028 Owen Building, Sheffield Hallam University, Howard Street, Sheffield, S1 1WB. Registration: http://oshug.org/event/37 An evening of talks exploring different commercial aspects of open source — hardware and software — including crowdfunding an open hardware microenterprise, navigating licensing issues, trade associations, and building a business on free software. Hosted in conjunction with the BCS Open Source Specialist Group. — Open Source Consortium - an introduction OSC is a trade association which represents companies and individuals delivering solutions and advice based on Open Standards and Free & Open Source Software. As a trade association, OSC gives its members greater influence than they could achieve alone by providing a collective voice, and by supporting initiatives such as the implementation of open standards in public sector IT, the inclusion of open standards in school curricula and levelling the gender balance in the industry. At the core of its vision, OSC campaigns for the use of Open Standards in all aspects of public and commercial life, promoting the unique advantages of Free & Open Source Software and the independent expertise offered by members. Irenie White has been Chair of the Open Source Consortium since 2013 after working with the organisation for 3 years. This year she was appointed as MD of credativ, a free software consulting and services company, after running operations there for 6 years. As a STEMNET Ambassador and through her work with Advancing Women in IT, Irenie is committed to supporting bottom-up growth in the wider technology industry. Outside of work her family comes first, music a close second. — Notes from the first three months of an Open Source Microenterprise * How I learned to stop worrying and love the Kickstarter Starting an Open Source Hardware business is lot of work, even if you've spent 11 years running a different one. There are all sorts of things you've forgotten about and there are a whole host of new challenges as you try to do things the right way from the start. None of it is easy, but all of it beats having a 9-5. Benjamin Gray is a proponent of Open Hardware, founder of MeArm, an open source robot arm manufacturer and phenoptix a recently retired maker business. Ben graduated from the University of Exeter with a chemistry degree and a fledgling phenoptix before moving to Nottingham to complete a PhD in theoretical physical chemistry. With 11 years of Maker business experience under his belt he's set out on a new adventure manufacturing the MeArm, a pocket sized robot arm. — But I didn't mean *that* Accidents and incidents exploring relationships between corporations and the licenses they use to share, from Creative Commons to GPL. Paul Beech used his graphic and web design skills to co-found Pimoroni, a maker company that does Raspberry Pi and Arduino stuff. Code: open source. Hardware: less so. — Giving it away: Free Software as a business strategy Bytemark Hosting has been involved in building, fixing and publishing Free Software since its foundation in 2002. Back then, free Software was seen as an unquestionable part of a winning business strategy for big firms, but within years firms that bet too much on it were brought down to earth. Matthew Bloch, Bytemark's MD, narrates his own company's successes, profitability and changes in strategy around this important social movement. Matthew Bloch is MD and co-founder of Bytemark Hosting, one of the UK's oldest and best-respected hosting and cloud providers, with its own data centre in York and staff of 23. Previous to Bytemark Matthew worked as a programmer on several Java virtual machines, and the PC emulator for Acorn computers. Compered by: Gareth Halfacree is a freelance technology journalist and the co-author of the Raspberry Pi User Guide, alongside project co-founder Eben Upton. He also writes the maker-centric Hobby Tech column for Custom PC Magazine, as well as numerous features in magazines including PC Pro, Linux User & Developer, Micro Mart, Computeractive and others. Formerly a system administrator working in the education sector, Gareth's passion for open source projects has followed him from one career to another and he can often be seen reviewing, documenting or even contributing to projects including GNU/Linux, LibreOffice, Fritzing and Arduino. He is also the creator of the Sleepduino and Burnduino open hardware projects and numerous small software tools, all released under permissive licences. Note: Please aim to arrive by 17:45 as the first talk will start at 18:00 prompt. //

Superoptimization and supercomputing talks, Wed 26th November at The RSA.
by Andrew Back 11 Nov '14

11 Nov '14

Hello, There are no hardware talks this month, but the BCS OSSG is hosting two talks on open source software with a "super" theme — supercomputing and superoptimization. Details and a link to registration are below. Also note that this month the venue is the Royal Society of Arts on The Strand, and not the BCS! Cheers, Andrew //// Location: The Prince Philip room Royal Society of Arts 8 John Adam Street London WC2N 6EZ Date: Wednesday 26 November Time: 6:00pm for 6:30pm start Price: Free for BCS members and non-members Booking link: https://events.bcs.org/book/1320/ (Please remember to book your place.) N.B. Note the change of venue, due to a double booking at the BCS. The RSA is just the other side of the strand from the BCS. map: RSA, 8+John+Adam+St,+London+WC2N, This month we have two talks on a "super" theme. Talk 1: Superoptimization: How fast can your code go. Speaker: James Pallister, University of Bristol Modern compiler optimization can take almost any code and produce a reasonably efficient binary at the end. However compiler "optimization" doesn't make your code "optimal", just better. In contrast, superoptimization can produce perfect code - the fastest, the smallest or the most energy efficient code. The technique, first introduced in the late 80s found in some cases it could do 25% better than the best assembly programmer, and 40% better than the best compiler at the time. Free software has always played a central role in superoptimization research, with the GNU Superoptimizer being one of the very first tools constructed. However there is a downside. Superoptimization today is incredibly demanding of compute time, so currently it is limited to short instruction sequences. At present it is most valuable in optimizing code hotspots and key library routines, and can also be a valuable aid to the compiler writer for peephole optimization. Recent research has developed new techniques that can make superoptimization more applicable to general code. In this talk I will introduce superoptimization and give some examples of the weird and wonderfully short sequences of code it produces. I will introduce the GNU superoptimizer and show how it is used, including some of the recent improvements I have contributed. The final part of my talk will look at the latest research including machine learning and constraint solving, and show how in future superoptimizers may be able to optimize much larger programs. Talk 2: Open-source Software in UK Scientific HPC Speakers: Neil Morgan and Phil Ridley, Hartree Centre, STFC Daresbury There are hundreds of scientific applications, libraries and tools that are used within the UK's academic HPC community and a large number of these are open-source. To demonstrate this usage and the benefits of open-source to this community, a short review of some of these will be given. Applications will be included which are used for performing atomistic and molecular simulations, computational fluid dynamics, and statistics for bioinformatics. All of these are able to utilise the capabilities of high end computing architectures with thousands of cores to facilitate new science. Furthermore, since efficient object code is of greatest importance in HPC, the use of open-source in compilers, tools and libraries will also be described. N.B. Note the change of venue to the RSA. Booking link: https://events.bcs.org/book/1320/ (Please remember to book your place.)

NON-profit
by Mark.itto 16 Oct '14

16 Oct '14

Hi, I Studied technical High school in Granada Nicaragua, the digital divide is still today with all the internet very big because of the purchasing power hence access to technology even cheap stuff we could consider cheap and accessible like Arduino and RPi. I want to donate some Arduino to my old school I looking for help on things like boards, accessories (sensors, motors...), and internet access(monthly cost). Does anyone have any experience running things like this? I'd like some advise on how to approach and find potential helpers. Im thinking 50 boards 1000£ in accessories Some way of sorting the internet maybe ask ISP for help? I'm also considering crowd funding and things like that. I live in London, so at the moment I'm looking for interested and trust-able people in the country itself. Looking for some expertise. xD Kind regards. MarcoP.

OSHUG #36 — Chips Pt. 2, Thursday 23rd October.
by Andrew Back 05 Oct '14

05 Oct '14

Hello, Registration is now open for the meeting October meeting. Details below. Regards, Andrew // Event #36 — Chips Pt.2 (Chip Design for Teenagers, Cocotb, lowRISC) 23rd October 2014, 18:00 - 20:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/36 Back in April 2011 we had our first meeting on the theme of open source chip design, and then around one year later we took a closer look at the OpenRISC Reference Platform System-on-Chip. The thirty-sixth meeting will feature talks on chip design for teenagers, an open source verification framework, and a fully open source system-on-chip that will be manufactured in volume. — Silicon Chip Design for Teenagers These days we expect school students to learn to write code, and teachers are turning to tools like Scratch (for primary education) and Python (for secondary education). But why stick to software languages. Why not teach coding in Verilog and get children to design silicon chips. Earlier this year Dan Gorringe attended Chip Hack II in Cambridge. Inspired by this he spent two weeks work experience at Embecosm in August 2014 modifying the Chip Hack materials for use by Year 9-11 students. His resulting application note, "Silicon Chip Design for Teenagers", is to be published very shortly by Embecosm. In this talk, Dan will share his experience of learning silicon chip design, using Verilog for his first serious attempt at coding and encountering Mentor Graphics EDA tools for the first time. Dan Gorringe has just started year 11 and faces the horrors of GCSE exams in 8 months time, so silicon chip design is just light relief. He has aspirations to a career in computing. — Cocotb, an Open Source Verification Framework Verifying hardware designs has always been a significant challenge but very few open-source tools have emerged to support this effort. The recent advances in verification to facilitate complex designs often depend on specialist knowledge and expensive software tools. In this talk we will look at Cocotb, an open-source verification framework, and explore whether Python is a viable language for verification. Chris Higgs has over a decade of experience working with FPGAs in various industries. His software background has shaped his approach to RTL design and verification and he now spends his time trying to bridge the divide between hardware and software development. — lowRISC — a Fully Open Source RISC-V System-on-Chip The lowRISC project has been formed to produce a System-on-Chip which will be open source right down to the HDL, implementing the open RISC-V instruction set architecture. Volume manufacture of silicon manufacture is planned, along with creating and distributing low-cost development boards. This talk will describe the aims of the lowRISC project, summarise its current status, describe some of the features that are being implemented, and give details on how you can get involved. Alex Bradbury is a researcher at the University of Cambridge Computer Laboratory where he works on compilation techniques for a novel many-core architecture. He writes LLVM Weekly, is co-author of Learning Python with Raspberry Pi, and has been a contributor to the Raspberry Pi project since the first alpha hardware was available. Note: Please aim to arrive by 18:15 as the first talk will start at 18:30 prompt. //

OSHW ARM dev board for NFC applications
by Donatien Garnier 25 Jul '14

25 Jul '14

Hi everyone, I have been working on a project that I would like to share with you. Some time ago I noticed that it was really hard to use NFC on embedded prototyping platforms (mbed, Arduino, etc) because of the lack of software available. Because of this I started developing a NFC library for embedded devices that supports tag reading, tag emulation and peer-to-peer (SNEP/Android beam) and it now works pretty well! To complete the development and make it available I am currently running a campaign for an open-source NFC development board which is mbed enabled (there is an ARM Cortex-M0 onboard you can reprogram using the mbed.org online platform). The board will be OSHW and I will open-source the NFC library as well. There is 48 hours left on the campaign that you can find here: https://www.kickstarter.com/projects/donatien-garnier/micronfcboard-easy-nf… Sorry for the bit of self-promotion but I really think this could be valuable to some of you! Cheers, -- Don

Baserock talk added to OSHCamp programme.
by Andrew Back 22 Jul '14

22 Jul '14

Hello, Just to let folks know that another talk has been added to the programme for this year's OSHCamp: an introduction to Baserock, a system for building custom embedded Linux distros directly from git, closely tracking the upstream projects and without packaging. "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." — http://oshug.org/event/oshcamp2014 Looking forward to find out more! Cheers, Andrew

Rust on ARM microcontrollers
by Ilya Dmitrichenko 21 Jul '14

21 Jul '14

Hi List, In the past few week I have got slightly involved with one project that some of you might appreciate. I suppose that some of you Amy have heard of a recently developed Rust programming language by Mozilla foundation. It's primarily aims are to reduce safety critical errors at compiler level and provide simple abstractions to the programmer normally seen in higher level languages, such as Ruby and Python, yet being a systems language that may potentially be used for an OS implementation instead of aging suspects. I do find Rust a pretty amazing language, and indeed, building on years of compiler practice, it has the real potential of becoming the next big affair of many embedded systems engineers. It doesn't, however, introduce a big overhead in code execution. The particular project that I have spent some time with is titled Zinc. It aims to implement an RTOS-like system that is capable of running on bare-metal microcontroller chips. Please check it out and drop any feedback to myself or as a question on the mailing list. http://zinc.rs http://rust-lang.org -- Ilya

Open Source Hardware Camp 2014, Sat 16 & Sun 17th August.
by Andrew Back 01 Jul '14

01 Jul '14

Hello, Registration is now open for OSHCamp 2014 and this year we will have in total 12 talks and 8 workshops — details below. Details for the Wuthering Bytes Festival Day on the Friday are yet to be announced, but there are some pretty great talks lined up, on topics ranging from development and testing of rockets, to being a computer programmer in the early 1960s. Speakers include Sophie Wilson, co-inventor of the ARM processor, and Open Rights Group. So, if you are considering attending on the Friday also, I wouldn't hang about as tickets are limited and likely to go fast! Cheers, Andrew // OSHCamp 2014 — 16 & 17th August at Hebden Bridge Town Hall, St. George's Street,Hebden Bridge, HX7 7BY. Registration: http://oshug.org/event/oshcamp2014 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. — 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 tails 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. William Stone is the Head of Channel Strategy for hardware manufacturer, Ciseco. He is responsible for various commercial areas of the business including the very familiar responsibility of growing Ciseco's rapidly expanding chain of partners and distributors. Now with 36 recognized distributors worldwide, Ciseco has a growing presence and reputation in electronics manufacturing and Internet of Things (IoT). * 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. Compered by: 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. — Sunday :: Workshops Some workshops will provide tools, boards and components etc. However, subject to demand this may involve an element of sharing and please feel free to bring along equipment and components, but note that you must be able to take full responsibility for your own personal safety and that of others in respect to these. Common sense must be exercised! * Let's build a flood network for Hebden Bridge! Split into two teams, one will attempt to install flood sensors on the beautiful Hebden Water just outside the venue, while the other links these these to the Internet using readily available technology. Proven hardware designs will be used to show you how can send water levels back to the Internet using low-powered wireless links, and sustainable approaches to citizen sensing will be explored. Run by: Ben Ward. Workshop notes: you may want to bring wellies if you plan to join the sensor installation team! Also feel free to bring sensors and boards that you think may be useful. * Building applications that sense and respond to the real world Following on from their talk, Naomi and Gareth will be joined by Paulo Marini, the Tormorden project's resident aquaponicist. Together they will facilitate a hack session to help you build applications that respond to the real world. Run by: Gareth Coleman and Dr Naomi Rosenberg. Workshop notes: Bring your own hardware to work on, such as Raspberry Pi and Arduino etc. if you can, and they'll try to find ways to get your projects connected. * Do you want to build a robot? #meArm assembly workshop How about starting with an Arm? With just a screwdriver and enthusiasm you can build an Open Source Robot Arm. If you bring an Arduino or Pi with you, you're free to stay on with your meArm and tinker with the code too. The meArm is a project to get low cost robot arms into the hands of as many people as possible. Started in February this year it's made fast progress through open development. Already "home brew" (those not from the laser forges of phenoptix in Nottingham) versions have been spotted in the UK, Switzerland, the USA and Mexico! Ben Gray is a proponent of Open Hardware and founder of phenoptix, a maker business based in Beeston, Nottinghamshire. Ben graduated from the University of Exeter with a chemistry degree and a fledgling phenoptix before moving to Nottingham to complete a PhD in theoretical physical chemistry. Through the open hardware movement he has been able explore the wonderful world of electronics and take phenoptix from a pocket money project to the full time job it is today. 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. * Building your first Parallella application This workshop follows on from the previous day's talk and participants will build a simple project which targets the Parallella board and uses all 16 cores of the Epiphany floating-point accelerator. Run by: Simon Cook. Workshop notes: Please bring along a laptop and, if you have one, a Parallella board (a limited number of boards will be available for use by those who do not own one). 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.itfor £4. Run by: Matt Venn. Workshop notes: bring along a laptop. * OpenTRV build and getting started Kits will be available to solder and boards and cables to buy, along with valves that will be used to demonstrate how you can use Arduino-based technology to halve your heating bill. Run by: Damon Hart-Davis. Workshop notes: Please bring your own soldering iron, solder and AA batteries if you would like to build a kit to take away, and be aware that SMD soldering experience and a steady hand will be required to solder the TMP112 temperature sensor. NOTE: * There are separate tickets for Friday, Saturday and Sunday. * A light lunch and refreshments will be provided each day. * Please aim to arrive between 09:00 and 09:15 on the Saturday as the event will start at 09:20 prompt. With thanks to sponsors: * DesignSpark - http://www.rs-online.com/designspark/electronics/ * XMOS - http://www.xmos.com
