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.

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.

    Embedded (Erlang, Parallella, Compiler Options and Energy Consumption)

    via OSHUG

    Embedded systems continue to grow in importance as they play an ever-increasing role in everyday life: more computing is done on the move as smartphone functionality catches up with desktops and services move to the Cloud; the Internet of Things is set to herald an age in which networked objects create and consume data on our behalves. These, and many other applications, are driving an insatiable demand for more powerful and energy-efficient embedded solutions.

    At the twenty-second OSHUG meeting we will hear how Erlang can be used to bring concurrency to multi-core embedded systems, we will learn about the Parallella project which aims to make parallel computing accessible to everyone, and we will hear about vital research into optimising compiler options for energy-efficiency.

    Erlang Embedded — Concurrent Blinkenlights and More!

    Managing the resources and utilising the increasingly popular multi-core and heterogeneous aspects of modern embedded systems require new sets of tools and methodologies that differ from the traditional C/C++ flow.

    Erlang provides features that are highly relevant to solve these issues and yet it is pretty much unknown in the embedded domain — which is surprising considering that it was originally designed for embedded applications at Ericsson!

    This talk aims to provide an overview of Erlang and the current state of its usage in the embedded domain and talk about our plans to help speed up the adoption rate of Erlang in embedded projects.

    Omer Kilic works on Erlang Embedded, a Knowledge Transfer Partnership project in collaboration with University of Kent. 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.

    Prior to 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 as part of his PhD thesis (which he intends to submit soon!)

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

    Parallella — Supercomputing for Everyone

    The Parallella computing platform is based on the Adapteva Epiphany processor. Implemented in 65nm or 28nm silicon, Epiphany offers 16 or 64 cores and delivers up to 50 GFLOPS/watt, and the entire Parallella board complete with a dual-core ARM A9 host will consume around 5 watts.

    This talk will present the Epiphany architecture and explore the challenges of developing an effective GNU tool chain, and discuss the use of open source, and an approach to engineering that developed one of the fastest chips in the world from concept to second generation silicon for just a few million dollars.

    Dr Jeremy Bennett is the founder of Embecosm, and an expert on hardware modelling and embedded software development. Prior to founding Embecosm, Dr Bennett was Vice President of ARC International PLC and previously Vice President of Marconi PLC.

    In his earlier academic career, he pursued academic research in computer architecture, modelling and compiler technology at Bath and Cambridge Universities. He is the author of the popular textbook "Introduction to Compiling Techniques" (McGraw-Hill 1990, 1995, 2003).

    Dr Bennett holds an MA and PhD in Computer Science from Cambridge University. He is a Member of the British Computer Society, a Chartered Engineer, a Chartered Information Technology Professional and Fellow of the Royal Society of Arts.

    Measuring the impact of compiler options on energy consumption in embedded platforms

    Energy efficiency is the highest priority for modern software-hardware co-design. The potential for compiler options to impact on power consumption of running programs has often been discussed. However there has never been a comprehensive analysis of the magnitude of that impact, or how it varies between processor architectures and compilers.

    This presentation will describe a project undertook during the the Summer of 2012 at the University of Bristol Department of Computer Science and funded by Embecosm, to explore the effect of compiler options on energy consumption of compiled programs.

    The talk will discuss the accurate measurement of power consumption on a range of small embedded systems. The whole setup was under control of an XMOS board, making it possible to run the tens of thousands of tests needed for statistical robustness in just a few weeks. The results of these tests will be discussed, the implications for compiling embedded systems, and the potential for future research in this area.

    This research was unusual, in that it was funded as a completely open project. A wiki detailed progress from week to week, the relevant open source communities were kept regularly informed, and the results will be published in open access journals. The talk will also cover the issues around funding and running an academic research project in this manner.

    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.

    Mr Pallister has 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.

    Simon Hollis is a lecturer in the Microelectronics Research Group, Department of Computer Science, University of Bristol. His interests lie in the creation of energy-efficient embedded systems, processor interconnects and parallel languages and run-times.

    He is the creator of the RasP and Skip-link Networks-on-Chip, and is currently working on the Swallow many-core system, which targets 480 processing cores in under 200W. A main aim of the research is to re-investigate the memory/communication balance in large scale computing systems.

    Note: Please aim to arrive for 18:45 or shortly after as the event will start at 19:00 prompt.
