Free Energy Efficiency Workshop: Bristol 16 January 2014
by Jeremy Bennett 18 Dec '13

18 Dec '13

Hi all, The Technology Strategy Board is running a workshop on energy efficiency tools in Bristol on 16 January, this is a free event aimed at anyone interested in the field: http://www.eventbrite.co.uk/e/energy-efficient-software-tools-workshop-tick… We'll be there with the new MAGEEC energy measurement boards (all free hardware design of course). Designed by Simon Hollis of Bristol University, these can sample energy usage up to 6 million times per second. It's a chance to bring along your own hardware and instrument it, or bring along your own software and try it on some standard boards. We'll have some ST Discovery (ARM) boards and Arduino/Shrimp boards to use if you'd rather not risk your own hardware. If you can't make it on the 16th, then there is a second chance to find out more about open source and energy efficiency, because we'll be re-running the workshop at FOSDEM as part of the energy efficiency dev room: https://fosdem.org/2014/ Hope to see you at one of these. Best wishes, Jeremy -- Tel: +44 (1590) 610184 Cell: +44 (7970) 676050 SkypeID: jeremybennett Twitter: @jeremypbennett Email: jeremy.bennett(a)embecosm.com Web: www.embecosm.com

[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

You're probably all aware of this, but if not: next year's Open Source Hardware Summit is likely to be in Europe, venue TBC. If you can come up with a compelling reason why Hebden Bridge is the ideal venue (and who can't?) then now is the time to get stuck into the discussion over on lists.oshwa.org. Best Andrew

OSHUG #30 call for talks!
by Andrew Back 08 Oct '13

08 Oct '13

Hello, We're in the process of planning the last OSHUG meeting of 2013, which is set to take place on Thursday 28th November at the offices of Erlang Solutions (thanks, Omer!) The theme that is developing is around re-purposing/over-clocking/reverse-engineering of hardware. As ever, there should ideally be an open source hardware aspect, e.g. over-clocking of OSHW, or perhaps an open source OSHW design for use with a over-clocked, modified or a reverse-engineered product. Although, talks on the wider principles, techniques and approaches etc. are welcome also. I'd like to try and get details together within the next week if possible. Cheers, Andrew

OSHUG #29 — Production by the Proletariat (RepRap, TVRRUG), 2nd October 2013.
by Andrew Back 17 Sep '13

17 Sep '13

Hello, Finally got round to putting up the event page for OSHUG #29. Looking at the BCS registration page there are just 14 tickets left. Cheers, Andrew // Event #29 — Production by the Proletariat (RepRap, TVRRUG) 2nd October 2013, 17:30 - 21:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/29 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. Registration: http://oshug.org/event/29

Hi All. I feel that this is relevant enough to post here. I've just created a 'Circuit Review' Stack Exchange proposal here: http://area51.stackexchange.com/proposals/58903/circuit-review?referrer=xPQ… I feel that we lack a place where we can post our schematics/layout/BOM and have people review them. This could be very useful for OSHW projects. In order to support this proposal, follow the link above, 'follow' it, suggest questions, and then promote on social networks ;) There's an equivalent site for code review that's already going: codereview.stackexchange.com cheers, saar.
