Lead the BCS Open Source Group
by Andy Bennett 12 Oct '22

12 Oct '22

Hi Oshugs! I hope everyone is well. OSHUG and the BCS Open Source Group have been holding joint meetings for some years now and it's nearly time for their AGM again. In fact, it's next Thursday (20th!). and we will be holding elections for all the positions In particular, our current chair has moved away from the UK and therefore we're looking for someone who might lead the group over the next year. The responsibilites are not onerous because there are others who take on a lot of the work of organising meetings. However, the candidate must be an active member of the BCS. If anyone is interested in standing for this position, please let me know and we can put you on the nominations list of next Thurday. If you're currently an active member of the BCS, please seriously consider applying! Best wishes, @ndy -- andyjpb(a)ashurst.eu.org http://www.ashurst.eu.org/ 0x7EBA75FF

spare dev boards
by Ilya Dmitrichenko 16 Mar '21

16 Mar '21

Hi Folks, I've got some boards that I don't have much use for since a few years now, and my field of work has shifted away from hardware. Having had these in my drawer for a few years, I doubt I'll get back to these in my spare time, and would like someone to have these, ideally someone who wouldn't be able to afford buying these brand new. I have compiled a list of all what I've got, please have a look here and feel free to reply directly or share: https://docs.google.com/document/d/1IyXKDG44M33ye8oGhTphg-HlSJKEezbZBOpKFL8… Ilya

Portugal provider NOS and 4G box
by LDV 19 Feb '21

19 Feb '21

Hi everyone, NOS is a provider here in portugal. They own the boxes you get when you have a 4G access with them. My contract is over. But I still have the hardware for the moment. I just got a concurrent prepaid 4G SIM. I tried to access the web interface on the LAN and it asked to insert a SIM. The box is Huawei hardware. (locked with NOS settings) When I tried the new SIM, I almost bricked/locked it but didn't. I could use that box a moment and give it back to them after their shop re-opens (locked-down !) Can I safelly install openWRT on it without damaging the hardware ? is it safe legally ? So if yes : could anyone give me directions to start. I have 5€ on my bank account (don't worry it's just to say : I must manage to do it) (nice exercise no ?) ;D Thanks in advance. -- /*____________________________________________________________________________*/ /* Louis-David VENANCIO aka Meta-4 /// +351.968.247.846 */ /* https://www.3DLibre.com owner. /* Rua das Romeirinhas, lote n°21 - 7540-187 Santiago-do-Cacèm - PORTUGAL */ /*____________________________________________________________________________*/

JTAG options
by Sevan Janiyan 18 Feb '21

18 Feb '21

Hello, I have some Meraki access points which I'd like to re-flash with OpenWRT as the devices with the stock firmware are useless without a contract to tie it into the hosted management platform and Cisco removed the command used to reflash the device from the firmware environment before they were EoLed, hence leaving the JTAG route as the only option. I was wondering, what is the cheapest device I can get away with for use with OpenOCD? Could I get away with using an SBC without investing in new hardware? Regards, Sevan

WB 2020 and OSHCamp cancelled.
by Andrew Back 16 Jul '20

16 Jul '20

It may come as little surprise to learn that the Wuthering Bytes festival is cancelled this year and so is Open Source Hardware Camp. That is, unless someone would like to take the lead on organising a mini online event around the same time, end August / early September. There were a few replies to the call and just prior to lockdown I pretty much stopped planning both events, so haven't approached any potential additional speakers. If there is interest in hosting something online just drop me a line off-list. Cheers, Andrew -- Andrew Back http://abopen.com

BCS OSSG / OSHUG July meeting: An Evening on the theme of FPGAs
by Sevan Janiyan 02 Jul '20

02 Jul '20

Hello, July's OSSG/OSHUG (online) meeting is happening on the 16th. We have three speakers giving talks on the theme of FPGAs. Details of talks as follows (registration link at the end) 1) Why the J-core open processor is cool The patents on the bestselling processor of the 1990’s finally expired, and it’s been cloned as open hardware. J-core scales from running SMP Linux down to fitting in a tiny 5000 cell ICE-40 FPGA, and we just uploaded a new open source GPS receiver built around it to github. Rob Landley maintains the J-core Board Support Package, used to maintain busybox, maintains toybox (the command line utilities used by Android), and used to be the linux kernel documentation maintainer. 2) Yosys and nextpnr – open source FPGA update Find out about the newest developments in Yosys and nextpnr, including experimental Xilinx support, synthesis improvements and new place and route algorithms! This talk will also discuss some of the future work that is planned, with an ambitious target to support 1-million-LUT scale designs on UltraScale+ devices by the end of the year. David Shah is a self-employed developer working on nextpnr, the open source FPGA place-and-route tool. His previous work also includes Project Trellis, open source bitstream documentation for the Lattice ECP5 FPGAs. 3) Repurposing Obsolete FPGA-based Products as Development Kits Commercial FPGA development boards can be relatively cheap or they can have a lot of logic resources and features, but never at the same time. When commercial products with large FPGAs become obsolete, they can often be found dirt cheap on eBay. With a little bit of effort, some of these products can be reverse engineered and repurposed as generic FPGA development kits. This talk will show some examples, and discuss techniques that can be used to reverse engineer these kind of products. Tom Verbeure is a hardware engineer at Nvidia where he works on monitor technology. Before Nvidia, he worked on communication ASICs at Barco, Alcatel and Conexant. When he’s not mountain biking in one of the many parks around the SF Bay Area, you can probably find him in his garage, looking through a microscope trying to trace tiny wires on an old PCB, or burning up an LED panel in a misguided attempt to control LED cube with a Cisco WAN modem.

OSHUG #78: LoRaWAN: Long Range Wireless for the Internet Of Things
by Andy Bennett 15 Apr '20

15 Apr '20

Hi All, Registration is now open for the 78th meeting, held in partnership with the BCS OSSG. Details below. This will be a remote meeting so you can enjoy the speakers and discussion with other attendees from the comfort of your own home. Cheers, Andy // 16th April 2020, 17:30 - 20:30 via BCS Webinar http://oshug.org/event/78 This month we’ll be hosting our evening of talks online. You can join remotely from the comfort of your own home to listen to the speakers and chat in realtime with the other attendees. LoRaWAN is a Long Range Wide Area Networking technology that has been quietly sitting in the background of many IoT systems for several years now. This month we’ll hear from speakers who were early adopters of the technology. We’ll find out what is it, how it works and, most importantly, what they have achieved with it. AGENDA 18:15 – Join online meeting to chat with other participants 18:30 – Presentations 20:30 – Close This is a joint meeting with the British Computer Society Open Source Specialist Group. We are currently finalising the details for registration and connection so please save this time in your diary and look out for more information on Tuesday 14th April. We shall be live streaming via GoToWebinar and recording the talks for later posting on YouTube. — LoRaWAN TBA. Andrew Tierney (@cybergibbons) — The Things Network 5 years on Amazing how time flies! Mike looks at how LPWAN has progressed since he first got involved with The Things Network in 2015. He will look at the technology (radio, devices and code) involved, how to build and deploy your project, and finish with a look to the future of TTN with 5G arriving. Mike Beardmore (@mikethebee) has surfed the wave of opportunities for a creator since the transistor replaced the ‘tube’. A life of learning about constant change has been a foundation for working with the recent LPWAN blooming. An active Maker using additive & subtractive tools, he is an advocate for Hackspaces, OpenSource and Creative Commons. — LoRa trials (and tribulations) A few years ago a group of us came together to see what we could do about measuring actual pollution levels “where you are”. We were disappointed that the only hyper-localised data available came from hard-to-trust models that used widely-spaced sensors. We won some funding to build and test a prototype based on good quality sensors that communicated via a connected smart phone to a cloud-based data store, the data being visualised on a web app. This allowed people to compare alternative routes and select the best ones. The main feedback from these trials was that we needed to make the device much easier to use, smaller and lighter so we looked at ways to make the sensor self-contained. Along came LoRaWAN as one way to achieve this. The prototype was completely redesigned and we have been testing and refining that since. Unhappily, trialling with schools is currently suspended for obvious reasons but we think we are getting there. The talk will be about our learnings and future options under consideration. Paul Tanner (@paul_tanner) is an experienced engineer and project manager. He has held management positions in several tech startups and developed numerous electronic and software products. He has worked on a diverse range of IT projects in the roles of CTO, project manager, developer and architect. Paul’s recent projects have been focused on practical implementation of the “Internet of Things”. These have included two consumer energy portals, an assisted living care-in-the-home system, an assistive street and an energy-optimised smart house and (currently) a portable pollution monitor. He has also been an advisor and beta tester for a smart heating product. Paul now focuses on “public good” projects, especially in renewable energy, assisted living and cleantech. He is open to whatever roles are appropriate either as an individual or by bringing in a small team. Paul is a graduate of MIT with a BS in Electrical Engineering. Whilst not busy with his family he is a “maker” and clean energy enthusiast. Note: Please aim to connect by 18:15 as the event will start at 18:30 prompt. -- Best wishes, @ndy -- andyjpb(a)ashurst.eu.org http://www.ashurst.eu.org/ 0x7EBA75FF

Open Source in Government (BCS OSSG)
by Andy Bennett 18 Feb '20

18 Feb '20

Hi OSHUG People, On the evening of Thursday, 20th February, the BCS Open Source Group are hosting an event on "Open Source in Government" in London. Registration is now open at https://ossg200220.eventbrite.co.uk/ We've got a good line-up of celebrity speakers: Open Source Excuses – busting the myths Terence Eden Why don’t government departments and NHS organisations want to adopt open source? This talk looks at common reasons given. It will give you real life examples of barriers to coding in the open, and practical tips for adopting open source. Terence Eden is the Head of Open Technology for NHSX. He is a technology & policy expert. He teaches government courses on AI and ethics. He was formerly the UK Government’s representative to the W3C. He speaks around the world on open standards, open source software, and open data. Current political challenges and opportunities for Open Source in Europe Astor Nummelin Carlberg The campaign to save Open Source development from the EU’s Copyright Directive was indicative of the current status of Open Source advocacy in the EU—while ultimately successful, it was more reactive than proactive. The most important lesson from this campaign was that Open Source was not targeted by policy makers, simply forgotten and misunderstood. This suggests that while Open Source has gone mainstream, Open Source advocacy has not kept up. As there are both more opportunities and regulatory risks for Open Source in the European Union, more, if not all, Open Source community stakeholders need to increase their capacity to deal with policy making. At the least, we need to make sure that Open Source never again becomes an unintended regulatory casualty. There are several very tangible steps that can be taken to do this. Since Open Source is becoming ubiquitous at the same time as there is an eagerness to regulate tech in the EU, the time is now to mature Open Source advocacy and increase its effectiveness. Astor Nummelin Carlberg is OpenForum Europe’s Policy Director, responsible for policy development and advocacy. Before joining the team he was an Accredited Parliamentary Assistant in the European Parliament, and has studied in the United States and Germany. He has extensive experience of European policy making processes, communications and catalysing networks and communities for advocacy impact. Making the case for open with Governments Irina Bolychevsky Irina Bolychevsky is the founder and director of Redecentralize.org. She’s a digital strategist and expert on data, open data, data platforms, standards, privacy and decentralised technology. She led the ckan open source data platform to international adoption, served on Open Knowledge Foundation’s senior management team and now as a board member and developed the personal data infrastructure programme within the UK’s Government Digital Service. She developed the Smart Dubai’s and UAE federal policy, regulatory, commercial and technical frameworks for data exchange and ran one of the first UK data trust pilots and researched digital identity for the Open Data Institute. The event page is here: https://ossg.bcs.org/blog/event/open-source-in-government/ ...and you can register for a (free) ticket here: https://ossg200220.eventbrite.co.uk/ Hopefully I'll see a few of you there! Whilst this is not an OSHUG event, it is organised by the BCS OSSG with whom we (OSHUG) often organise joint open source events. I thought it might be of interest to some of you.

BCS OSSG/OSHUG: An Evening on Modern Programming Languages
by Sevan Janiyan 29 Oct '19

29 Oct '19

Hello, During this evening, held jointly with OSHUG, we look at the latest in open source programming languages. Three talks from three highly respected speakers Note. We are in the new BCS London offices at 25 Copthall Ave EC2R 7BP. Register at https://ossg211119.eventbrite.co.uk/ Tea/coffee will be served from 6:00pm, with the talks from 6:30pm. Each talk will last around 30 to 45 minutes including any questions. We shall be livestreaming and recording the talks for later posting on YouTube via GoToWebinar. Please register at: https://attendee.gotowebinar.com/register/2652791007348976652 An introduction to Perl6 Simon Proctor An introduction to the newest version of Perl with an emphasis on some neat features. With 17 years as a professional web developer (in a range of languages) and over 30 years of doing it for fun Simon Proctor has just about started to understand what he’s doing. He’s on occasion been known to take things seriously. Julia – A fresh approach to numerical computing Avik Sengupta In this talk, Avik will demonstrate how Julia combines dynamic, high level source with a high performance runtime code. He will show what makes Julia unique among programming languages, and how it enables high quality numeric computing libraries. He will survey the machine learning / deep learning ecosystem in Julia, and talk about how that can be extended to new kinds of modelling using differentiable programming. The talk will begin as an introduction to the language, and finish by showing how it opens up new paradigms of computing. Julia is the fastest high performance open source computing language for data, analytics, algorithmic trading, machine learning, artificial intelligence, and many other fields. Julia solves the two language problem by combining the ease of use of Python and R with the speed of C++. Avik Sengupta is the head of product development and software engineering at Julia Computing, contributor to open source Julia and maintainer of several Julia packages. Avik is the author of Julia High Performance, co-founder of two artificial intelligence start-ups in the financial services sector and creator of large complex trading systems for the world’s leading investment banks. Prior to Julia Computing, Avik was co-founder and CTO at AlgoCircle and at Itellix, director at Lab49 and head of algorithmic solutions at Decimal Point Analytics. Avik earned his MS in Computational Finance at Carnegie Mellon and MBA Finance at the Indian Institute of Management in Bangalore. Evolving Languages: 5 Steps to Go Charles Forsyth Go is the latest of a sequence of closely related concurrent programming languages: Squeak, Newsqueak, Alef, Limbo and Go. Each one strictly followed its predecessor, they occupy a similar space (CSP-inspired concurrent languages), and all but Squeak have a vaguely similar syntax, perhaps suggesting gradual refinement and incremental evolution. I take a closer look, revealing their significant differences, especially in in type systems and run-time environments, reflecting the effect of different design choices to satisfy the requirements of a larger, surrounding system. Dr Charles Forsyth is a founder and Technical Director of Vita Nuova, which specialises in systems software and distributed systems. He is interested in compilers, operating systems, networking (protocols and services), security, and distributed systems and algorithms. He specialises in the design and implementation of systems software, from low-level drivers through compilers to whole operating systems. He has published papers on operating systems, Ada compilation, worst-case execution analysers for safety-critical applications, “resources as files”, and the development of computational grids.

Dev kit swap desk at OSHCamp
by Omer Kilic 24 Aug '19

24 Aug '19

One man's development board collecting dust in a cupboard is another man's future weekend project, right? Given that OSHCamp attendees are a curious bunch, I encourage you to bring your unused and destined to landfill dev kits over to Hebden Bridge so they can potentially be rehomed. We'll have a table where you can drop them off and if any other kit catches your fancy, you can take it back home with you. I am bringing a bunch of ARM dev boards (Nucleo/Freedom Board/etc), a couple of interesting breakouts, an EFM32 kits that I'm pretty sure I've acquired from the same swap desk a few OSHCamps back and a BLE dev kit. Cheers, Omer.

Open Source Hardware Camp 2019 — Sat 31st August & Sun 1st September, Hebden Bridge.
by Andrew Back 18 Aug '19

18 Aug '19

Hi All, I'm pleased to announce that we have a total of 11 talks and 6 workshops confirmed for Open Source Hardware Camp 2019! As in previous years, there will be a social event on the Saturday evening and OSHCamp is once again being hosted to coincide with the Wuthering Bytes technology festival. http://wutheringbytes.com/ Cheers, Andrew // Open Source Hardware Camp 2019 On the 31st August 2019, 09:00 Saturday morning - 16:00 on the Sunday afternoon at Hebden Bridge Town Hall, St. George's Street, Hebden Bridge, HX7 7BY, UK. Registration: http://oshug.org/event/oshcamp2019 Open Source Hardware Camp 2019 will take place place in the Pennine town of Hebden Bridge, where it will return to be hosted for the sixth year as part of the Wuthering Bytes technology festival. Hebden Bridge is approximately 1 hour by rail from Leeds and Manchester. Budget accommodation is available at the Hebden Bridge Hostel which adjoins the venue, with private rooms available and discounts for group bookings. Details of other local accommodation can be found at www.hebdenbridge.co.uk. There will be a social event on the Saturday evening from 8PM.. *** Saturday :: Talks *** — Customising a RISC-V Core This talk walks through the RISC-V ISA and the microarchitecture of an open-source RISC-V core, to provide an understanding of how new instructions can be added to the hardware. RISC-V is an open Instruction Set Architecture (ISA) that can be implemented freely. The ISA is modular, providing a base set of integer instructions alongside standard extensions for multiplication, floating point, atomic operations, and many other categories. In addition to standard extensions, the ISA reserves space for user-defined extensions, providing the flexibility to add custom instructions that fulfil any purpose. There are many open-source implementations of RISC-V cores - in this talk we will look at a small core written in SystemVerilog that is simple enough to be understood by those relatively new digital logic design. We will walk through the different components of the core and how they fit together to build a picture of how instructions are decoded and executed, and go through an example of the changes to each component needed to support a custom instruction. * Dr Graham Markall is a software toolchain engineer at Embecosm, which provides open source toolchain services. Most of his work focuses on GNU toolchains (GCC, Binutils, GDB, etc.) and the use of cycle-accurate simulation for pre-silicon toolchain development and testing. His current projects focus on the development of customised toolchains for various RISC-V systems, ranging from small, deeply-embedded applications up to high-performance multicore systems. — Building A Network on a Chip for a Raspberry Pi Zero Cluster A Raspberry Pi cluster is a popular platform for experimentation and learning about parallel computing. The tiny Raspberry Pi Zero has no built-in ethernet capability, so a Pi Zero cluster needs an alternative way to connect the CPUs. By implementing a specialised local network on an FPGA chip, linked to a serial or SPI port on each CPU, we can avoid the need for bulky ethernet cables and switches, and build a very compact cluster with low cost and low power consumption. * As a member of Oxford University's Programming Research Group in the 1980s, Richard Miller wrote software for parallel computing systems from the transputer to the Cray T3D. More recently as a freelance software engineer, he ported the Plan 9 operating system to the Raspberry Pi. His current focus is on FPGA circuit design. — From humble beginnings to manufacturing the HILTOP open source test and measurement platform and the problems along the way! The story of how three entrepreneurs with a vision and willingness to succeed have carved out an open source test and measurement business and the details behind the hardware and software problems they had with early prototypes and product integration. * Tim Telford is a hardware engineer with diverse skill set and highly motivated self starter. Passionate about design detail and experienced in high reliability solutions for the Aerospace, Defence, Telecoms and Nuclear industries. Development of test equipment and measurement systems for Rolls-Royce Aerospace. Systems and Electronic engineering experience within the nuclear industry. Design of commercial test equipment and high integrity, high value projects. Analogue and Digital board level design, Schematics, PCB, FPGA development, DFM, DFT, Simulation, systems design and integration/testing. Requirements management, FMEA, WCA & PSA analysis techniques. * Joe Burmeister spent nearly 12 years in the console and PC game industry. He worked in a number of areas from graphics and animation engine to art and animation tools, finally file systems and databases. Joe comes from a multiple platform background, partly as consoles used to not be PCs, but also having grown up on RISC OS (Acorn’s desktop ARM OS), before moving to Windows for work then Linux for fun and finally work. For the past five years Joe has done work on GNU/Linux, often on ARM. Having started out bedroom programming, Joe is a strong believer that everyone should have the option of source code and learning how things work. — Linux on Open Source Hardware and Libre Silicon This talk will explore Open Source Hardware projects relevant to Linux, including boards like BeagleBone, Olimex OLinuXino, Giant board and more. Looking at the benefits and challenges of designing Open Source Hardware for a Linux system, along with BeagleBoard.org's experience of working with community, manufacturers, and distributors to create an Open Source Hardware platform. In closing also looking at the future, Libre Silicon like RISC-V designs, and where this might take Linux. * Drew Fustini is an Open Source Hardware designer at OSH Park, board member of the BeagleBoard Foundation, maintainer of the Adafruit BeagleBone Python library, and Open Source Hardware Association vice president. — Exploring the Gigatron TTL Computer The Gigatron TTL computer is an open source computer constructed almost entirely from TTL logic - without the need for a microprocessor. The unique design combines 36 standard 74HCTxx TTL devices with ROM and RAM chips to make a platform capable of colour VGA video and sound. The machine can host 1980's style games and can be programmed in interactive Tiny BASIC. In the last year, Ken has explored the architecture of this machine and achieves some performance gains by overclocking the cpu by over 200%. This has yielded a platform that is rated at about 2 to 3 times the performance of the classic 1980's machines, such as the C64, Spectrum etc. Working with an unfamiliar architecture has meant creating some programming tools and also simulating the machine behaviour on an ARM processor. Ken discusses the progress to date - and poses the question, "What would computers be like had the microprocessor not appeared when it did?" * Ken Boak began programming computers in 1979 at school, and has * continued to do so - somewhat infrequently over the last 40 years. The Gigatron rekindles old memories of TTL logic and working with resource limited computing. It illustrates just how much can be done with such a minimal machine. — Gearing up for Volume Manufacturing: Tales from China The journey of a design from engineering sign-off all the way to customer shipment takes many months of hard work and the smallest of hiccups could translate to severe delays. With many actors involved, how does it all work? What is involved in designing and shipping a consumer product with high volume manufacturing in mind? This talk will give the audience a behind the scenes look at what it takes to ship electronics products at scale, particularly focusing on the approach, dialogue and the processes required to run a successful manufacturing project. * Omer Kilic is an embedded systems engineer who works at the various intersections of hardware and software engineering practices, product development and manufacturing. — Saving Your Electronic Conference Badge From A Life On The Shelf As the creator of an electronic conference badge, you want to create something memorable, a badge with Wow! factor which will be remembered fondly and remain in use for years afterwards. Unfortunately so many badges end up sitting in drawers gathering dust, never to see the light of day again. Firmware,hardware, or documentation haven't been kind to the conference attendees, and though you've given them an amazing piece of hardware they just haven't been able to get a handle on it and use it in their own projects. This talk gives a few ideas about how that might be avoided, how an awesome badge can avoid being an ignominious piece of e-waste and become a valued piece of hardware used in projects for years afterwards. * Jenny List is an electronic engineer and technical writer who spent a long career in electronic publishing from CD-ROMs to dictionaries before breaking out and forming her own hardware business, and writing about hardware as a contributing editor for Hackaday.com. — What's So Good About The Z80 CPU Anyway? This talk will briefly cover the history of the Zilog Z80 CPU including early development, some predictable places where it turned up, as well as some more less expected uses. It will include a look at the architecture of the Z80 itself and then an overview of how to build a simple Z80 based computer and program it in BASIC. This will lead on to a description of the kit in your goodie bag and a plug for the workshop on the Sunday. * Spencer Owen like many kids in the 80s, loved his ZX Spectrum and other 8 bit computers. This set him up for a career in IT, and he worked as a server engineer and network engineer for many years. In 2013, in a bid to see if he really understood how computers worked at the lowest level, Spencer went back to his roots built a simple Z80 based machine on a breadboard. This was to mature in to the RC2014, which Spencer started selling in his spare time in 2015. Within a few months it was clear that the RC2014 was taking up more time than he had spare, so he quit network job and started a retro computer kit company. Spencer is now the largest supplier of Z80 computers worldwide. — Next Generation Open Source FPGAs After the success of Icestorm and the growth of the open source FPGA ecosystem, work started on the next generation of open source FPGA toolchains in 2018. This includes the next-generation place-and-route tool nextpnr, designed to support a wide range of FPGA architectures as well as producing higher quality results with less runtime. Combined with Project Trellis which provides bitstream documentation for the Lattice ECP5 FPGAs, a wide range of advanced projects such as Linux-capable RISC-V SoCs with fast memory, Ethernet and video interfaces are possible with an end-to-end open source flow. This talk will introduce these new tools and their capabilities, as well as discussing what lies ahead for open source FPGA tools, and how you can get involved in this exciting new open world! * David Shah is a engineer at Symbiotic EDA and a Electronic and Information Engineering student at Imperial College London. He entered the world of open source FPGAs by extending Project Icestorm, the iCE40 bitstream documentation project, to include the newer iCE40 UltraPlus FPGAs. As well developing Project Trellis, he has been involved in the development of a new open source FPGA place-and-route tool, nextpnr. — Heterogeneous design for embedded development Developing embedded solutions for today's challenging applications be them IoT, consumer, automation or robotics requires a heterogeneous technology approach involving hardware, FPGA, µC Firmware, and software combined at multiple levels. Concepts such as Machine Vision/Learning, Artificial Intelligence coupled with traditional embedded hardware and software stacks require hybrid approaches to design and implementation. I take a look at typical hardware being used and platform sweet spots I have been identified. I also take a look at some emerging tools and approaches for tackling these heterogeneous projects. * Alan Wood has been working with parallel distributed programming for several decades. His recent work includes smart grids, 3D printers, robotics, automation and biotec diagnostics. His current research is focused on machine learning for embedded automation using FPGA and µC. He is a long term advocate of open source communities, a moderator (aka Folknology) for xCORE, the co-founder of myStorm open hardware FPGA community, as well as a co-founder of Surrey and Hampshire Makerspace. — EMC Design for Open Source Hardware Many Open Source electronics designs start off as cool development tools and end up being integrated into commercial products due to their low barrier to entry and ease of development. Now your hardware becomes subject to various Regulatory requirements, Electro-Magnetic Compatibility (EMC) amongst them. Whilst it might not be viable for an Open Source project to undergo full compliance testing, there are things that can be done to improve the EMC performance of your system. In this talk, James gives an overview of common problems encountered during EMC testing of Open Source hardware and the fixes required to resolve them. We'll also look at some key electromagnetic concepts (don't worry, no scary maths) that will help you look at your designs in a new light. * James Pawson runs Unit 3 Compliance, a West Yorkshire EMC test lab and consultancy that offers practical advice and EMC problem solving for a wide range of electronics products. *** Sunday :: Workshops *** — Customising a RISC-V Core - workshop Starting from an Open-source RISC-V core, add a new instruction to it that you design! This workshop will walk through the process of getting started with simulating an open-source RISC-V core and making the necessary modifications to decode and execute a new instruction. A processor that supports a new instruction is not much good if you can't write any code for it, so the second part of the workshop will focus on adding support into the assembler for your new instruction, so that you can write a program using the instruction and see that it executes correctly (or does not, and helps you to work out the bugs in your implementation). The tutorial materials will provide enough of the implementation and sufficient guidance to be able to work through with a little experience of Verilog and C++. For those new to Verilog, the materials from last year's talk and workshop ("Introduction to cycle-accurate Verilog simulation" and "Open Source RISC-V core quickstart") will be available to provide a more accessible starting point. Participants should bring: - A laptop. * Run by: Graham Markall — A Crash Course in KiCAD A KiCAD basics workshop that will be a crash course covering the main aspects of schematic capture, PCB layout and generating the manufacturing outputs and 3D models etc. Participants should bring: - A laptop with KiCAD version 5 installed ready to go. * Run by: Tim Telford — Gigatron TTL Computer demo and hands-on There will be a demo of the machine and an opportunity to do some retro-programming. * Run by: Ken Boak — SMD Soldering In this workshop we will introduce common SMD soldering techniques, including stencils and solder paste usage in a hobbyist home-lab capacity. The format is a series of demonstrations followed by exercises. Participants will be provided with a kit of parts and will assemble their circuits taking turns on the equipment provided. There will be a mixture of hand soldering and hot plate/air reflow techniques covered and a variety of SMD packages including some fine pitch components will be used. Participant requirements: - Some familiarity with soldering and electronics in general would be beneficial. * Run by: Omer Kilic — Assembling Your RC2014 Z80 Based Computer This workshop will take participants through all the stages of assembling and getting started with the RC2014 kit. Some basic soldering experience is assumed and soldering irons and tools will be available for groups of up to 6 people at a time. There will be a nominal charge of £5 per person. Participants should bring: - A laptop. - An FTDI cable if they have one. — Heterogeneous embedded hardware example walk through A walk through a practical heterogeneous application and its development, based around the combination of a microcontroller and an FPGA along with mixed tooling. * Run by: Alan Wood NOTE: - There are separate tickets for Saturday and Sunday. - A light lunch and refreshments will be provided each day. - Delegates will receive an RC2014 Micro upon registration on the - Saturday! - Please aim to arrive between 09:00 and 09:15 on the Saturday as the event will start at 09:20 prompt. // -- Andrew Back http://abopen.com

OSHUG #74 — What's New In Cryptography & Security, Thurs 18th July.
by Andrew Back 08 Jul '19

08 Jul '19

Hi All, Registration is now open for the 74th meeting, held in partnership with the BCS OSSG. Details below. Cheers, Andrew // Event #74 — What's New In Cryptography & Security 18th July 2019, 18:30 - 20:30 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. http://oshug.org/event/74 Over the last few years the security landscape has changed in several major ways. The Internet Of Things has made security and privacy a major problem for everyone. The move to HTTPS on almost every site and the attacks on TLS have raised awareness of security on the web, As a result, there has been a renewed focus on open source cryptography libraries, including new forks and projects. This meeting will take a look at the current state of security and cryptography and we'll look at how open source is contributing to the solutions as well as the problems. This is a joint meeting with the British Computer Society Open Source Specialist Group. — Failures in Firmware, an analysis of common weaknesses in IOT devices The advent of the Internet of Things has created an industry filled with incredible technologies, and incredible vulnerabilities. This talk aims to outline common weaknesses in these devices that can occur even if the developers are trying their best to make a device secure. This will include problems that can occur when implementing standard functionality, such as authentication, firmware updates, secure communication and protection of sensitive data. This talk will cover the following topics, with demonstrations and recommendations: - The basics of cryptography, how it works, how it is implemented, and the different types of software which implement it. This will include an introduction to Open Source encryption libraries and the pitfalls that can occur when they are implemented incorrectly. - An introduction to Open Source libraries used for developing embedded software, including an assessment of example libraries for specific chipsets which contain known vulnerabilities. - Demonstration of weaknesses in firmware protection mechanisms, covering what happens when you don't secure your firmware, when you encrypt it, and when you sign it. This topic will cover exactly how an attacker could bypass protection mechanisms when they are incorrectly implemented, and how they can be implemented well. - An analysis of Linux vs Real Time Operating Systems, demonstrating the security strengths and weaknesses between the two approaches and what can be done to improve the security of both. - A demonstration of weaknesses that can occur in hardware, demonstrating what can occur when electronics are designed in a manner which allows for easy debugging, including a demonstration of how firmware can easily be removed from a device when it is not adequately secured. - A discussion of how Open Source libraries can both increase and decrease security in a product, and how they can be used effectively. Each element of this presentation will include working demonstrations in order to exemplify where the weaknesses lie in the standard approaches taken when creating an IOT product. * Christopher Wade is a seasoned security researcher and consultant. His main focuses are in reverse engineering hardware, finger-printing USB vulnerabilities and playing with Software Defined Radios, His key strength lies in firmware analysis, which he utilises as part of the hardware testing team at Pen Test Partners. — Should you choose Open Source Crypto? What are the arguments for and against for using open source crypto code and how have they changed over time. * Glyn Wintle is CTO at dxwcyber, a security consultancy focused on attack. He has extensive experience of breaking into computer systems in both the public and private sector. — Why and How you should start using Onion Networking The internet began as a network where any computer could communicate directly with any other; but today there are host firewalls, perimeter firewalls, content filters, NATs, DNS restrictions, BGP hijacks and all manner of other challenges that limit you and your computers' ability to communicate. The Tor "Onion" networking protocol is an alternate "disintermediated" layer 3 stack where you do not require permission nor (mostly) any setup in order to communicate directly from/to any well-known address, plus you gain a host of security & operational benefits. We describe this. * Alec Muffett has worked in host and network security for 30 years, more than 22 of those in industry, holding senior consulting, architecture and engineering roles at Sun Microsystems and Facebook. He is a member of the Board of Directors of the Open Rights Group, a member of the Security and Privacy Executive of the British Computer Society, and a security engineer at Deliveroo. Note: Please aim to arrive by 18:15 as the event will start at 18:30 prompt. -- Andrew Back http://abopen.com
