by Andrew Back 20 May '24

20 May '24

Hello, I'm pleased to announce that we have a total of 12 talks and 4 workshops confirmed for Open Source Hardware Camp 2024! 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. https://wutheringbytes.com The programme for Wuthering Bytes Festival Day (Fri 23/08) should be announced within the coming weeks and for details of speakers confirmed so far, see: https://wutheringbytes.com/whatson/festival-day Regards, Andrew // Open Source Hardware Camp 2024 On the 24th August 2024, 09:00 Saturday morning - 16:00 on the Sunday afternoon at The Birchcliffe Centre, Birchcliffe Road, Hebden Bridge, West Yorkshire, HX7 8DG, UK. Registration: https://www.eventbrite.co.uk/e/open-source-hardware-camp-2024-tickets-90883… Open Source Hardware Camp 2024 will take place in the Pennine town of Hebden Bridge, where it will be hosted 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. Details of other local accommodation can be found at www.hebdenbridge.co.uk and via Airbnb and Booking.com etc. There will be a social event on the Saturday evening from 7PM. *** Saturday :: Talks *** — Adventures in Manufacturing: Things you don’t learn at school This talk is an open book of our collective experiences, filled with the kind of know-how that can only be picked up from the factory floor. Join us for a candid conversation where we peel back the curtain on the world of electronics product manufacturing. Expect invaluable lessons learned from the ground up, offering practical advice wrapped in entertaining stories. * Stuart Childs has spent the past few years working in the strange space between engineers, product owners and factories — setting up production lines and working with a variety of suppliers, from prototypes to mass production. * Omer Kilic is an Embedded Systems and Manufacturing Consultant who works at the various intersections of hardware and software engineering practices, product development and manufacturing. — Open Source Rocketry Tools, FreeCAD and beyond Rocketry has its challenges, but there are numerous open source tools available to enable the design, simulation and manufacture of amateur, high power and experimental airframes. In this talk Jo will show some of these tools and usage, highlighting along the way how it’s only open source community development that could possibly enable such interesting and interoperable tools to be developed. * Jo Hinchliffe is a technical author, maker, and community developer who has an interest in space. Jo has developed and flown numerous open source rocket designs and has pushed the development of open source rocketry tools. Jo has worked with Libre Space Foundation who built and launched a completely open source satellite off the International Space Station, as well as other on orbit open source space projects. Jo has a wide range of clients he writes for and is the author of “FreeCAD for Makers” available for free download from the Raspberry Pi Press. — The National Museum of Computing EDSAC Replica EDSAC was the first practical general purpose, stored program, electronic, digital computer and provided a computing service for the University of Cambridge. It ran its first program (Squares of 1 – 100) on 6th May1949. Because of the significance of EDSAC to British Computing, it was decided to create a replica at TNMOC. Our task is to build a working reconstruction of EDSAC as it was at the start of its life, providing the world’s first computing service from 1949 to 1958. Money was raised from around 2010, and design work started a couple of years later. With the paper tape reader not yet available, we use an Arduino-based Solid State Injector unit to program the computer, and a Cypress FX2 USB2 clone as a logic analyser with PulseView software. Raspberry Pi Picos are also used as wireless logic analysers. * Tony Abbey received a BSc in Electronic Engineering in 1968 at Southampton University and went on to work for the East Midlands Gas Board on communications and instrumentation, where he found that computers could be used for control purposes. There he worked on the Westinghouse “DP2 and a half” computer and DEC PDP11 systems. After EMGAS he worked for 35 years at Leicester University Space Research Dept, where he designed and commissioned X-ray detectors for satellites, getting to Cape Canaveral twice and French Guyana for three satellite launces. He still has cryogenically cooled CCDs in space in the satellites XMM-Newton, Swift and Astrosat, and he provides consulting services as a director of Helaton Services, together with his wife. In retirement Tony has been a director of Leicester Hackspace and he also finds time to race a K1 dinghy at Rutland Water. Software-defined radio has been an interest for several years and helping out at TNMOC has been occupying a lot of his time. — Look, no FPGA! When creating a robust WiFi logic analyser, it is tempting to use complex programmable logic devices; however, there are alternatives, as this talk will show. The end-result is a low-cost unit using a Pi RP2040 microcontroller that can store 500,000 16-bit samples and stream them at high speed across a WiFi network to a Web browser. I’ll be describing simple techniques to tackle the various hardware, software and networking issues, with an end-result that is applicable for a wide range of data-streaming applications – without requiring any logic programming. * Jeremy Bentham has been experimenting with electronics from an early age. After graduating with an engineering degree, he worked for London Undergound, specialising in 600-volt DC railway traction systems, and on-train electronics. On leaving LUL, he worked for various Cambridge startup companies, including a one-person consultancy specialising in embedded systems hardware & software development. Based on this experience, he wrote the book ‘TCP/IP Lean’, selling over 15,000 copies in 2 editions, and was recruited by a small vehicle tracking company to create the hardware and software for their tracking systems, of which over 500,000 units were installed. In retirement, his interest in railway engineering was re-ignited by joining a team restoring a 1938-vintage 'Q' stock underground train to run in heritage service, and another team creating a 7 ¼ inch narrow-gauge railway. He was also asked to create some high-speed wireless logic analyser units for the valve-based EDSAC computer that has been built at the National Museum of Computing in Bletchley. His open-source projects are freely available (no advertisements) on iosoft.blog. — Dye Sublimation Printing on PCBs PCB colour choices have come a long way since the green of the 1980s, and it seems like every colour of the rainbow is available. But when Spencer decided to make a Pride based rainbow coloured modular computer in 2023, he found the choices offered by the PCB fabs to be far too limited. The solution he found was dye sublimation. This talk is about how this works with PCBs, the workflow he developed, obstacles overcome and how cheap equipment can be used to set up your own dye sublimation production line. It covers the advantages of printing your own full colour PCBs, and also some of the disadvantages and where it is not suitable. * Spencer Owen is a self confessed retro computer geek. In 2013 he built a Z80 based breadboard computer which went on to become the RC2014 kit computer. Since quitting a life in IT in 2016 for this little modular computer, it has taken him to events all over the world. He is passionate about hobby electronics, and always keen to try doing the things that other people haven’t done yet. — Continuous Integration for Semiconductors - how Tiny Tapeout makes chips Continuous integration has long been taken for granted by software engineers, but acceptance is still growing in hardware engineers. In this talk, Matt will show how we leverage GitHub Actions to build documentation, create FPGA bitstreams, run tests and create all the files needed to manufacture an open source chip. Together, these automated jobs allow us to regularly manufacture chips filled with hundreds of tiny designs with minimal manual intervention. * Matthew Venn is is a science & technology communicator and electronic engineer. He has been involved with open source silicon for the last 4 years and has sent 20 chips for manufacture. He has helped over 400 people learn the tools through his course, with hundreds more sending designs for manufacture via Tiny Tapeout. — Revisiting the Bit-Serial Computer Architecture Developed near the dawn of the electronic computing age, around the end of WW2, the bit-serial architecture played an important role in computing and calculating machines, as a result of its simplicity and low component count. Indeed up until about 1960, bit-serial l was the mainstay of computing architecture, as a result of being significantly cheaper than a parallel architecture. Similarly, in the late 1960s bit-serial was adopted for most of the early desktop and pocket electronic calculators. This talk explores the bit-serial architecture and reveals how it is still relevant today, some 80 years on. * Ken Boak has been tinkering with electronics and computing for over five decades. His 6th birthday present was a soldering iron! He has interests in minimal computing devices and pre-1981 computer history. Ken currently works in the renewables field, on hydrogen fuel cells and the conversion of ammonia to hydrogen fuel for stationary and marine internal combustion engines. — STEAM Punk Sunflower Andy has been pondering how to build an "interesting" take on an LED matrix since the mid-90s. At last year's OSHCamp, the swap table offered a glut of LEDs and control chips that finally gave him the push he needed. After the conference he went back home and set to work. Taking inspiration from Jiří Praus, Mohite Bhoite and one maths professor's website that he's referred to for far too many projects, he designed something that he hopes is an original take on an LED matrix. At it's heart, this talk will be an OSHCamp community story that covers the scientific, technological, electronic, artistic and mathematical basis for a LED sunflower sculpture. * Andy Bennett trained as an Electronic & Electrical Engineer and has a background in consumer electronics, FPGAs, operating systems and device drivers. For the last 15 years he has been building companies around distributed database technology. He is currently Director of Register Dynamics who help companies and governments apply their data usefully, responsibly and ethically. Andy is a Technologist that likes to inhabit the void between users, software and the hardware that it all runs on. His love of ceramic taps is well-documented. — Building digital cameras for fun and science This talk gives an introduction to how CMOS digital cameras work, from the diode up. It goes on to describe some custom cameras designed to make modulated light measurements and their scientific applications. The modulated light technique can be used with conventional cameras or photodiodes by using lower modulation frequencies. * Roger Light did a PhD in Electronic Engineering at the University of Nottingham, then moved on to being a researcher and finally lecturer, designing various scientific camera chips along the way, to help with problems ranging from biological measurement, to characterisation of grain structure in metals. Back in 2009 Roger started the Mosquitto MQTT broker project, and as a now ex-academic he is working as a software developer at Cedalo, who offer support and extra functionality for Mosquitto. He still hankers after building more cameras. — Cost Cutting OSHW with Crafty Concurrency Embedded hardware and software need to tackle both real-time responses to concurrent real world demands and events, further it needs to do this in a predictable, deterministic and safe manner. How can we achieve these seemingly irreconcilable goals? Moreover is it possible do do so with basic tooling and without incurring excessive manpower and costs. As someone who battles these challenges with multi disciplined professional teams for fully funded commercial projects, you might be surprised that Alan has discovered a secret low cost formula that anyone can source and develop using fully open source tooling. He will open Pandora's box so you can take a peek. * Alan Wood has been working with parallel distributed programming for several decades. His recent work includes smart grids, 3D printers, robotics, automation biotec diagnostics and flow computation. His current research is focused on multilayer concurrency and mixed language models for complex embedded systems. 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. — Showing that you care about security for your open source (hardware) project Software Bill of Materials (SBOM), Supply-chain Levels for Software Aritfacts (SLSA) and Open Source Security Foundation (OpenSSF) Scorecards form a trifecta of security practices and deliverables that let people know that you're paying attention to the security of your project. This presentation will begin with an overview of the trifecta, looking at why each is needed and how they relate to each other. It will then go into practical steps to incorporate them into a project repo. We will also look at the ongoing maintenance involved once scorecards have been implemented, and how aspects of that maintenance can be better automated to minimize toil. * Chris Swan has been tinkering with electronics since he was at primary school, and got into software when he realised that it was necessary to make hardware do interesting things. In his day job as an Engineer at Atsign, he's helping to build the atPlatform, a Networking 2.0 technology that is putting people in control of their data and removing the frictions and surveillance associated with today’s Internet. On evenings and weekends he can often be found making some sort of project around a dev board, which have mostly been RISC-V recently. Chris is an InfoQ Editor writing about cloud, DevOps and security, he co-hosts the Tech Debt Burndown Podcast and is a Dart Google Developer Expert (GDE). — Why is my robot doing that? Live visualisation of sensor data Many sensors are a lot cheaper than they used to be. Ultrasonic, IR, time of flight and even lidar are (kind of) within budget for enthusiasts, and you can write code against them fairly easily. But when debugging, it's really handy to look at the raw sensor data in a format that isn't just raw numbers, and that's where data visualisation techniques can help. In this talk, I'll discuss, with easy examples, how data visualisation can help you work out why your robot is going the wrong way. * Rick Walker used to be a real scientist, but since leaving academia the only thing he sciences is data. He likes clear explanations, cares a lot about effective data visualization, and wishes he was better with robots. // Compered by: // Kevin Murrell is a trustee of The National Museum of Computing with a particular interest in computer technology from the 1950s and 1960s. Kevin recently completed a rebuild of the Wireless World Computer which was published in 1967. During working hours, Kevin is technical director of a UK software house providing systems for the UK, Canada and Ireland. Kevin is the proud owner of a Myford Super 7 - which occupies his spare time! *** Sunday :: Workshops *** — Bit Serial Computing Build your own bit serial computer from modern 74HC series logic. The workshop introduces the concepts of bit serial arithmetic, starting with a simple ALU. The addition of a timing sequence generator and memory allows 8-bit computation to be performed. There will be a limit of 20 participants on the workshop, and a £20 charge to cover the cost of PCBs, components and consumables. Participants should bring: - A laptop and if possible install "H. Neemann's "Digital" simulator from his GitHub repository. Run by: Ken Boak. — Dye Sublimation Printing on PCBs Following on from the talk yesterday, Spencer will provide some simple blinky LED PCBs and show you how to get your colourful designs on to it. If you have a laptop with you, you will be able to use an Inkscape template to create your design. This could be something unique that you have drawn yourself, or any drawing or photo that you want to use. Alternatively, fountain pens with CYMK ink can be provided to make a totally one-off design. Once printed and cooled down the PCB can be assembled, so basic through-hole soldering experience may be required. Participants should bring: - A laptop with Inkscape installed. Run by: Spencer Owen. — Retro Computing Simulation Some of us hanker after an original minicomputer with all the switches and lights but no longer have access to the hardware. Indeed, few of us have the space required to recreate installations from those early days when disk drives were the size of washing machines! There are excellent software emulations of many of these early systems, but the excitement of operating a functioning front panel cannot be beaten! We will show the systems running and welcome user interaction. So, get out the old CP/M handbook and the DEC Introduction to Programming and off we go! We expect to be demonstrating the following running replicas: - Wireless World Computer - Raspberry Pi-based PDP8 - Raspberry Pi-based PDP11 - LGP-30 - IMSAI 8080 - Raspberry Pi-based PDP10 — possibly just the unboxing! Participants should bring: - A laptop. Run by: Kevin Murrell. — Raftabar the Robot A follow-up to the Festival Day talk of the same title. This is not a workshop in the normal sense and there will not be any pre-organised hands-on tasks. It’s more of a casual/informal drop-in to see Raftabar performing, and for more comprehensive and technical discussion about his construction and innermost secrets. We can talk about: - Mechanical construction using MDF, plastic and metal – No 3D printing I’m afraid, although in many cases it would have made a much better job than my hacksaw, file, pedestal drill and lathe. - A bit of analogue electronics. - Ultrasonic obstacle detection and distance measurement. - PWM motor and servo control. - How to follow a light beam back to bed. - PID control. - Raftbar’s software uses several finite-state machines, something that Rod is quite passionate about and loves to talk about. - Running multiple Python 3 scripts on a Raspberry Pi and communicating between scripts. - Invoking Python 3 scripts on Raspberry Pi boot-up. - Raspberry Pi LAN and communication to PC using RealVNC. - Raspberry Pi to Raspberry Pi serial communication using UART. - Face detection and recognition. - Audio speech to text conversion and Text to audio conversion. Rod emphasises that he is not an expert in all areas, but will do his best to explain the principles. * Rod Moody was born in 1940 and at 15 years of age started an electrical engineering apprenticeship with Dale Electric, a manufacturer of diesel-engine driven electrical generators ranging from a few kW to a few MW, for both base load and standby applications. Through day release and night class he gained an HNC in electrical engineering, and at the age of 19 was appointed to the post of Test Department Manager. He went on to become Electrical Engineering Manager responsible for running the design office and designing control systems using relay logic, and following which Engineering Director. In 1992, at 52 years of age Rod joined Deep Sea Electronics as their Engineering Manager. DSE were quite small at that time and using through-hole technology, but with improved product design and the introduction of SMT production they grew very rapidly over the eight years before Rod retired in year 2000 at 60 years of age. DSE are now the leading supplier of microprocessor based controllers to generating set manufacturing companies worldwide. In retirement Rod spends most of his spare time with projects involving mechanics, electronics, and software using the Raspberry Pi and Arduino microcontrollers. He continues to be a keen gardener as he has been from an early age, has a keen interest in all aspects of science and engineering, and is currently leader of the York U3A Science & Engineering World group. NOTE: - There are separate tickets for Saturday and Sunday. - A light lunch will be provided each day. - Please aim to arrive between 09:00 and 09:15 on the Saturday as the event will start at 09:20 prompt. -- Andrew Back https://abopen.com

Upcoming Meetings in London
by Andy Bennett 18 Jan '24

18 Jan '24

Hi all, It was great to see so many people at the Christmas drinks. Since then, Omer and I have been chatting about how to get something going in London again. We'd like to solicit some feedback on our proposed format (below) and also to invite you to submit your proposals for talks on this Google Form: https://forms.gle/rBQopohr6UHWNRcq9 Our goals are to do in person meetups in/around Central London because we received a lot of feedback where people said that it was the personal community feel that was most valuable. Online events of talks don't seem to be much better than pre-recorded talks that you can consume in your own time. We'd like to propose a similar but slightly different format to the old one. 2 or 3 slots per session of no more than 30 minutes each, with plenty of time for questions. We'd like to have a larger social aspect to the evening, including time during the event for 5->10 minute lightning talks or show and tell sessions. There are a lot of people doing lots of interesting things but who can't commit to a big talk. This could also be a channel for periodic updates on ongoing projects from people who are working on something and who would like input or who do not feel they are finished enough to present a longer talk. The evening would start with a meet-and-greet at the venue, but perhaps with food or snacks, depending on the host. After the talks we would retire to the pub, but hopefully early enough that people can stay for at least one drink before leaving for trains. For now we'd like to solicit some feedback on this format and also to invite you to submit your proposals for talks on this Google Form: https://forms.gle/rBQopohr6UHWNRcq9 We're aiming to set up a pipeline of events so that when we launch we can be sure to have events regularly. Best wishes, @ndy -- andyjpb(a)ashurst.eu.org http://www.ashurst.eu.org/ 0x7EBA75FF

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. https://wutheringbytes.com/ <http://wutheringbytes.com/> The programme for Festival Day (Fri 25/08) should be announced within the coming weeks and for details of speakers confirmed so far, see: https://wutheringbytes.com/whatson/festival-day Cheers, Andrew // Open Source Hardware Camp 2023 On the 26th August 2023, 09:00 Saturday morning - 16:00 on the Sunday afternoon at Hebden Bridge Town Hall, St. George's Street, Hebden Bridge, HX7 7BY, UK (53.742436, -2.012918) Registration: https://oshcamp2023.eventbrite.co.uk/ Open Source Hardware Camp 2023 will take place in the Pennine town of Hebden Bridge, where it will return to be hosted 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 and via Airbnb and Booking.com etc. There will be a social event on the Saturday evening from 8PM. *** Saturday :: Talks *** — Life beyond 2-layer FR4: A high-speed peek into the world of PCBs The perfect combination of open source tools exponentially getting better and the availability of affordable and easy-to-use printed circuit board manufacturing services have enabled many folks to get their weekend projects “fabbed”. While laying out a 2-layer board is relatively straightforward, there is a much wider world when one gets into the nitty-gritty of the humble circuit board for more complex designs. From materials and finishes to multi-layer stack-ups and exotic drilling and milling options, we will take a quick peek at the world of printed circuit boards. * Omer Kilic is an Embedded Systems and Manufacturing Consultant who works at the various intersections of hardware and software engineering practices, product development and manufacturing. — Automated irrigation using a novel approach to determine soil moisture level Rod spoke at OSHCamp 2017 about his greenhouse and garden automation project in York, with particular emphasis on his design of a capacitance sensor for measuring soil moisture level. In 2019 he undertook another project near Scarborough on the East coast of Yorkshire, this time to irrigate 16 vegetable planting areas in a one acre garden. The project went into service in the spring of that year and has continued to work very successfully up to the present time. As with the previous garden project, the Arduino Mega2560 was used but a number of problems were envisaged using capacitance probes. This talk will largely focus on the novel approach used to determine soil moisture level without the need for physical soil moisture sensors. Instead, employing a predictive algorithm that uses rainfall and climatic temperature and humidity to derive the soil moisture level of each planting area. * Rod Moody was born in 1940, and at 15 years of age started an electrical engineering apprenticeship with Dale Electric, a manufacturer of diesel-engine driven electrical generators ranging from a few kW to a few MW for both base load and standby applications. Through day release and night class he gained an HNC in electrical engineering, and at the age of 19 was appointed to the post of Test Department Manager, this led to many trips around the world to provide commissioning, trouble shooting and training. In his mid-twenties he was appointed to the position of Electrical Engineering Manager responsible for running the design office and designing control systems using relay logic. As technology advanced, and as a self-taught electronics engineer, he designed complex control systems using CMOS logic, and alternator AVRs using semiconductor analogue technology. In his early thirties Rod was appointed to the position of Engineering Director. In 1992, at 52 years of age he joined Deep Sea Electronics as their Engineering Manager. DSE were quite small at that time using through-hole technology, but through improved product design and the introduction of SMT production they grew very rapidly over the eight years before Rod retired in year 2000 at 60 years of age. DSE are now the leading supplier of microprocessor based controllers to generating set manufacturing companies worldwide. In retirement Rod spends most of his spare time with projects involving mechanics, electronics, and software using Raspberry Pi and Arduino microcontrollers. He continues to be a keen gardener as he has been from an early age, has a keen interest in all aspects of science and engineering, and is leader of the York U3A Science & Engineering World group. The Missing Bit: Recovering data from magnetic discs — The Missing Bit: Recovering data from magnetic discs Magnetic discs were - from the 1970s - how computer data was stored. A technical deep-dive into how these relics can be read using modern equipment, by digital an analogue means, and how to handle the problems which creep in. * By training Phil Pemberton is a software engineer, electronics hobbyist and ham radio operator from Leeds. In his spare time he plays with old computers, reverse-engineers old radio equipment, and tries valiantly to fix his house without destroying it in the process. Phil is an active member of the Stardot retrocomputing community and can often be seen recovering strange and unusual data from magnetic discs. — The story of Älgen guitar: how to mix traditional hand-craft woodwork with cutting edge digital fabrication Michael spent the last year designing and building a novel guitar that tries to bring in the best of both traditional luthiery and cutting edge digital fabrication techniques like 3D-printing (not just plastic, but also metal and carbon fibre), and generative design. The result is Älgen, a light-weight, visually distinct, uniquely engineered instrument. This talk will focus on the design behind the guitar, looking at what you can do with generative design and 3D-printing, how to interface the old and new construction techniques (e.g., mating a walnut body with 3D printed nylon sides), and how to decide what bits to do with which technique. * By training Michael Dales is a Software Engineer with experience in numerous Cambridge startups and more established companies, and currently works at the University of Cambridge, helping ecologists build tools and methodologies for assessing the impact of climate change on biodiversity of plants and animals. By passion Michael builds custom guitars and guitar related things: whilst he has a love for the craft that goes into hand-build instruments, he also has an equal love for new manufacturing techniques such as generative-design and 3D-printing in metal, and has branched out into building instruments that sit at the intersection of those two worlds. — MicroPython for Hardware Hackers Nowadays it should only be necessary to use assembly language for the most demanding and time-critical applications. MicroPython is a port of Python to microcontroller hardware. This talk, followed by workshop on the second day of OSHCamp, explains how the Python programmer interacts with various typical pieces of hardware, and gives you the opportunity to get some hands-on experience. * Steve Holden has worked with computers since 1967 and started using Python at version 1.4 in 1995. He has since written about Python, created instructor-led training, delivered it to an international audience, and built 40 hours of video training for “reluctant Python users.” An Emeritus Fellow of the Python Software Foundation, Steve served as a director of the Foundation for eight years and as its chairman for three; he created PyCon, the Python community's international conference series and was presented with the Frank Willison Award for services to the Python community. He lives in Hastings, England and works as Technical Architect for the UK Department for International Trade, where he is responsible for the systems that maintain and regulate the trading environment. — Why not build an oscilloscope? How hard can it be? Tom will discuss the trials and tribulations in building a mid-performance digital oscilloscope (1 gigasample per second 8-bit ADC, 100MHz bandwidth, 4 channels) using a Xilinx Zynq FPGA, a Raspberry Pi, and a few leaked datasheets. In the talk, he will discuss what he learned about oscilloscope architecture, FPGA's and the Raspberry Pi's camera interface, what he'd do differently, and why he did it (because, well, how hard can it be?) There may be a demonstration. The project is open source and available on GitHub. * Tom Oldbury is an electronics, FPGA and software engineer now living and working in Cambridgeshire, currently working for a company designing and manufacturing thermal imaging systems. He studied Electronics Engineering at the University of Leeds, but has been playing with electronics and software from a young age. — Reinventing the Single 8 home movie format When home movies on 8mm film were king, there was a format war between Kodak's Super 8 and Fuji's SIngle 8. Just like Sony's Betamax in the home video wars, Fuji's technically superior contender lost the battle, and the final Single 8 cartridges were manufactured in about2010. The physical dimensions of the film are the same though, so here in 2023 it should be possible to load a SIngle 8 camera with film from a Super 8 cartridge. This is the story of the revival and reinvention of a lost film format through OpenSCAD and 3D printing, done mostly without an original cartridge to copy. * Jenny List is an electronic engineer and technical journalist, writing mostly as a contributing editor for hackaday.com. — Open Hardware in Bio Labs and Clinical Diagnostics Technology — even when developed for consumer use — has great potential in healthcare and clinical applications, and open source hardware can speed development. We enthusiastically use open source hardware in our biomedical technology research group, for example to shrink critical diagnostic microbiology tests and transport them out of the lab closer to patients. We will present our experience developing a simple to build open source robotic microfluidic blood test platform built around Raspberry Pi imaging. However, although clinical diagnostic testing used to rely entirely on fully open and totally transparent methods, a strong recent trend has replaced these with closed proprietary products. In this "double act" Ruya will describe the benefits of open source technology for a biomedical engineering PhD student, then Al will raise some bigger questions and discussion points about trends in science and technology, such as: Are we losing the ability to make medical decisions based on fully understood and publicly shared testing methods? Could open source hardware avoid this problem? Is it possible to return to open access and transparency in clinical diagnostics? * Al Edwards is Associate Professor in Biomedical Technology, and has been exploring ways to improve diagnosis of a range of clinically important health problems, from heart attack to bacterial infection, for nearly 15 years. One major aim is to simplify complex laboratory instrumentation using the latest components, such as smartphone cameras. Wherever possible our laboratory uses open source hardware, although we also work towards commercialisation to ensure our developments can become useful products. * Ruya Meltem Sariyer is currently finishing her PhD using miniaturised blood tests towards improved epidemiology of cardiovascular disease. Arriving in the UK in the depths of covid-19 lab closure, she was able to start building an open source imaging system in her room using a Raspberry Pi zero. Alongside her doctoral laboratory research into blood tests to measure variation in cardiovascular function, she has explored the use of open source hardware as an alternative to expensive lab instruments. — The Fuller Stack Engineer The abstractions on which we build software go so much further than what the software industry normally considers a "Full Stack Engineer". This term really just covers the tip of the iceberg. Going lower, into the realm of circuit boards, micro-controllers, and even silicon, is easier than ever. It no longer means working with nasty chemicals, proprietary software, expensive development boards, low level programming languages or processes that are only available to businesses willing to shell out extremely large sums of currency units. I'll explore some of the open software, libraries, tools, that are now available, as well as hardware, services, and educational resources that make it possible, and comparatively easy, to explore the entire tech stack: From GUIs all the way down to doped silicon. Join me on my quest to become a Fuller Stack Engineer, it has never been easier. * Christian Jacobsen is a “fuller stack" engineer. When he isn't procrastinating on writing an ODBC to REST bridge for KiCad, he writes largeish Python backends and tinkers with hardware design. He is an active open-source contributor and in a previous life he ran occam code on a lot of small computers. — Breaking proprietary smart home lock-in: untangling OpenThread and does it Matter? Will the promising Thread and Matter standards and their open source implementations free us from proprietary smart home solutions, and what advantages does it offer for security, privacy and reliability? * Andrew Robinson. Bio to follow. — The Open Source Keyboard Matrix - A dive down into the Open Source keyboard rabbit hole A fun journey into the world of Open Source keyboards. Most folks accept the keyboard that comes with a PC without even thinking about it, however many of us want to build or hack our own personal keyboard designs. This leads to a wide diversity of interesting bespoke keyboards. We will take a journey through this diversity and explain common requirements and features available to hack your very own personalised keyboard. We will look at the OpenSource hardware and the software that enable the concoction of virtually any keyboard design. You will get to dive into the keyboard rabbit hole and see just how deep it goes. * 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. — LibreCores CI - why did it fail? And did it? In 2016 the FOSSi Foundation presented the LibreCores project — an attempt to build an all-in-one hub for open digital hardware developers. To some extent it was an open source rebuild of OpenCores with many added value solutions like LibreCores CI which was presented in 2017 at Hebden Bridge. In 2022 the whole LibreCores infrastructure was shut down, although many bits remain available to end users in GitHub repositories. This talk is a retrospective on the project of building a reusable CI solution for open hardware projects. Let's talk about what worked there and what didn't, and what could be done better to sustain an open hardware and open EDA project. Please talk would be useful to contributors and especially maintainers who want to ensure a long-term sustainability of their projects and attract more contributors. * Oleg Nenashev is a serial community builder currently working on WireMock and WireMock Cloud ecosystems. He's passionate open source software and open hardware advocate. Oleg is a core maintainer and board member in the Jenkins project where he writes code, mentors contributors and organizes community events. He is a TOC member in the Continuous Delivery Foundation, and also a CDF and CNCF ambassador. Oleg has a PhD degree in electronics design and volunteers in the Free and Open Source Silicon Foundation. /\/ Compered by: /\/ Kevin Murrell is is a trustee of The National Museum of Computing with a particular interest in computer technology from the 1950s and 1960s. Kevin recently completed a rebuild of the Wireless World Computer which was published in 1967. During working hours, Kevin is technical director of a UK software house providing systems for the UK, Canada and Ireland. Kevin is the proud owner of a Myford Super 7 - which occupies his spare time! *** Sunday :: Workshops *** — Solder Paste and Stencil Workshop - Build your own WiFi Device! This hands-on workshop demonstrates the usage of solder paste and stencils with SMD devices in a hobbyist home-lab capacity.

by Andy Bennett 14 Oct '22

14 Oct '22

Hi Oshugs! I hope everyone is well. Thanks Andy for letting me post this on the announce list! 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 my eMail to the talk list I said that this would be next week but we have now moved it to November to give ourselves more time to make arrangements. At that meeting 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 for the AGM. 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

Open Source Hardware Camp 2019 — Sat 31st August & Sun 1st September, Hebden Bridge.
by Andrew Back 07 Jun '19

07 Jun '19

Hello, We are 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. https://wutheringbytes.com/ Regards, 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.
