OSHUG #32 -- Embedded Scripting, 27th March 2014.
by Andrew Back 27 Feb '14

27 Feb '14

Hello, Registration is now open for the March meeting. Details below. Regards, Andrew // Event #32 -- Embedded Scripting (Lua, Espruino, Micro Python) 27th March 2014, 17:30 - 20:30 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/32 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.

OpenData + Wearable devices hackathon! 15-16th March at TechHub, Manchester.
by Andrew Back 13 Feb '14

13 Feb '14

Hello, Details below of an open data/wearables hackathon that may be of interest to folks. Cheers, Andrew // OpenData + Wearable devices hackathon! 15-16th March at TechHub, Manchester. Open Data - Wearable devices - HACK! Registration: https://www.eventbrite.co.uk/e/numbers-that-matter-hackathon-tickets-103683… - What? We've done our studies. We've transcribed audio, shadowed people, documented their stories, captured their concerns, and been receptive to their ideas. We have a body of work relating to what kind of numbers matter to them, how we could realise them, and what kind of devices would work in the field. This leads to our hackathon. We have a body of documentation we'll make available about what people want, how they understand and relate to data around them, and ideas for possible devices. You'll be able to explore and help realise these ideas - either as they are, or from your own perspective. We'll have equipment for you to use, from Raspberry Pis to Arduinos, and experts on-hand who will help you get to prototype. The overall winner from the day, as voted for by a panel of judges, will win the opportunity to take their prototype to a full field trial with support from the Numbers That Matter team. - Who We encourage collaboration between participants - if you don't already have a team to work with, you can meet up with people at the start of the event. It's easier to complete a hack if there's a range of skills and people working together. We'll be making working prototypes of hardware and software on the day, so people with experience in these fields are important team members. Design is a key aspect of usable devices and experiences - teams will need these skills to anticipate and plan meaningful devices Analysis and data processing skills will be needed in your team - knowledge of existing formats and platforms can speed development on the day Entry is open to anyone; professional developers, activist hackers, design students, anthropologists, sociologists, geeks and social entrepreneurs are welcome, as is anyone who feels they can contribute to the day.

Hardware project input required
by Chris Puttick 07 Feb '14

07 Feb '14

Hi all I've been asked if I can find someone who can provide design input for a product prototype. Project concept has been described to me as follows: a wearable tech device involving tracking and collecting motion data (probably using a gyroscope and accelerometer) and transmit it back to a mobile device wirelessly. Please feel free to ask questions and I'll try and get more detail if I can, or contact me off list to express an interest in being intro'd to the project owner. Thanks Chris -- @putt1ck putt1ck.blogspot.com http://twoten.is skype: putt1ck Opinions in this email are my own and may not reflect that of my clients, past employers, associates, friends, family, pets etc..

Fixing a date for OSHCamp 2014.
by Andrew Back 07 Feb '14

07 Feb '14

Hi All, Last year's OSHCamp was something of an experiment — hosting it as part of Wuthering Bytes — and based on how the event went overall and feedback, we've decided to do something a bit different this year. The idea is that OSHCamp will still be hosted as part of Wuthering Bytes, but that the latter will become more of a festival comprised of a series of events: * OSHCamp will have the Waterfront Hall to itself on the Saturday (10x talks) and Sunday (workshops). * On the Friday there will be a day of talks in the Waterfront Hall on a much broader range of topics (think of the non-OSHUG and crossover talks from WB 2013), with accompanying workshops upstairs in The Space on the Saturday. * Main social event Friday evening. * A number of smaller/fringe events in the week leading up. The dates we are looking at are: August 15/16/17 September 19/20/21 And ideally we need to decide on August or September ASAP. So, any preferences? Improved chances of better weather in August, but obviously a lot of people go away on holiday. Which may not be a bad thing, if you want to take a break in Hebden Bridge :o) Best, Andrew

OSHUG #31 — Privacy and Security, 20th February 2014.
by Andrew Back 22 Jan '14

22 Jan '14

Hello, Registration is now open for the first OSHUG meeting of 2014! Details below. Regards, Andrew // Event #31 — Privacy and Security (Security protocols in constrained environments, RFIDler, Indie Phone) 20th February 2014, 17:30 - 20:30 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/31 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. — Indie: a tale of privacy, civil liberties, and a phone Can a phone really help protect our civil liberties? Aral Balkan thinks so. And he’s embarked on an audacious journey to make one. Join us to hear the introduction of a two-year story that is only just beginning. Aral Balkan is is founder and designer of Indie Phone, a phone that empowers mere mortals to own their own data. Note: Please aim to by 18:15 as the first talk will start at 18:30 prompt.

Hi All, Firstly, save the date: the first meeting of 2014 will take place on Thursday 20th February. The theme is going to be along the lines of security/privacy and there are two talks already confirmed and looking for a third. I was wondering if anyone knew someone who was involved with the FreedomBox project, or perhaps knew enough about it to give a talk on it themselves? Suggestions of other device and networks security and privacy related talks are also welcomed. Cheers, Andrew

[job advert warning!] Boldport
by Saar Drimer 08 Dec '13

08 Dec '13

Hello everyone. I hope no one would be offended by this advert, but I wanted to get the word out there, and there is a strong connection to open source hardware ;) As some of you know, I run Boldport, where I create "beautifully functional circuits" and maintain the Python open source PCB design software, PCBmodE. (You may have seen some of my work at Wuthering Bytes and my OSHUG presentations.) I'm looking for someone to join me. The technical background isn't as critical as our ability to work together and that the person joining understands and is passionate about the vision for what we aim to achieve together. If there's a right match, there is an opportunity to join at a co-founder level. I have a somewhat generic job advert on Boldport's site: http://www.boldport.com/work.html Other information about the company, the work, the vision, and PCBmodE is here: http://boldport.com http://boldport.blogspot.com http://www.youtube.com/user/boldport http://bitbucket.org/boldport/pcbmode Thanks for your attention, and I look forward to hearing from anyone who is interested. Please forward this on to others if it's relevant to them. All the best, saar.

OSHUG #30 — Speed (overclocking, souped-up BBC Micro, compiler optimisation), 28th November 2013.
by Andrew Back 08 Nov '13

08 Nov '13

Hello, Registration for the last OSHUG of 2013 is now open, and it looks like it's going to be a fun one! Cheers, Andrew // Event #30 — Speed (overclocking, souped-up BBC Micro, compiler optimisation) 28th November 2013, 18:00 - 20:00 at Erlang Solutions, New Loom House, 101 Back Church Lane, London, E1 1LU. Registration: http://oshug.org/event/30 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 isoverclocking 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. Note: Please aim to arrive for 18:15 as the event will start at 18:30 prompt.

Xmos Startkit
by Alan Wood 18 Oct '13

18 Oct '13

Those who know me or have or have attended some of my earlier (pre TVRRUG) OSHUG talks will be aware that I frequently work with Xmos multicore micro-controllers among my many other favourite technologies. Xmos are a UK chip design company (like ARM) who are doing a lot of work to push the technology envelope and they extensively use Opensource tool chains along with their community opensource libraries at xcore ( https://github.com/xcore). They have recently made efforts to widen their product lines and lower the barrier to entry, if you are interested in exploring XS1 technology and perhaps adding to their opensource developer pool you might be interested in a special promotion they are running called Startkit where they are giving away some great simple development boards for folks that may have a good idea to try out on them. Anyhow I don't want this to appear to much like an advert but I really respect what these folks are doing and hope that this doesn't put anyone off by posting it here on OSHUG You can find the offer here: https://github.com/xcore regards Al
