OSHUG #71 — Machines and systems of past, present, future, Thurs 17th January.
by Andrew Back 16 Jan '19

16 Jan '19

Hi All, Registration is now open for the 71st meeting, held in partnership with the BCS OSSG. Details below. Cheers, Andrew // Event #71 — Machines and systems of past, present, future On the 17 January 2019, 18:30 - 20:30 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. http://oshug.org/event/71 To start off the year, we have a series of talks around the theme of Acorn computers, RISC OS, RISC-V toolchain. This is a joint meeting with the British Computer Society Open Source Specialist Group. — Brief history of Unix-like operating systems on Acorn hardware Stephen Borrill first encountered Unix while working for a PhD in Psychoacoustics and as a long-term Acorn user, his Acorn RiscPC was his hardware of choice to run it on. While finishing his PhD, Stephen started a part-time job at Acorn Computers working in technical support. This led to full-time employment at Acorn and Xemplar (an Acorn and Apple joint venture focussed on UK education) during which he developed products based on BSD Unix on Acorn hardware which were sold nationally. In 1999 Stephen founded Precedence Technologies who took over support and development of the products he worked on at Acorn and Xemplar. He continues to with the products 20 years later. — RISC OS : What's Next As of 2018, RISC OS is an open source operating system. This talk will cover the heritage of RISC OS, direction it would like to go, the response since it was open sourced as well as a demo of the latest computers that run RISC OS. * Richard Brown is a co-founder and director of RISC OS Developments Ltd. Since its inception in April 2017, Richard has been a driving force in making RISC OS truly open source; this was achieved with significant funding and community support in November 2018. Richard is also the sole director of GeneSys Developments Ltd, an IT company, which additionally incorporates Orpheus Internet, an ISP company. Despite not having a 'techie' background, Richard would end up assisting or implementing IT solutions for the companies he worked for. Taking the opportunity to further his technical knowledge and experience, Richard went on to work in the IT industry and set up his own business in 1995. In the early 80's, Richard spent some time in Canada. Here, he worked in the camera industry where he acquired advanced skills in photography, a love of which had been instilled in Richard as a young person by his father and continues to be a key skill in his career to date. — Embedded FreeBSD on a five-core RISC-V processor using LLVM We were tasked with bringing up and testing embedded FreeBSD on a custom five-core 32/64-bit RISC-V processor using LLVM. Given FreeBSD has already been ported to RISC-V and LLVM is the standard BSD C/C++ compiler surely this should be easy. But it wasn't. LLVM for RISC-V is still relatively immature, particularly for 64-bit. FreeBSD runs on symmetric multi-core 64-bit QEMU RISC-V, but not on embedded systems and not on heterogeneous multicore systems. In this talk we'll go through the steps needed to bring up a functioning embedded FreeBSD system on multi-core heterogeneous RISC-V system. Our target hardware was not available at the start of the project, so we used the generally available HiFive Freedom Unleashed board. The result is a reference embedded FreeBSD implementation for RISC-V, freely available to the community. This is not a talk about the deep internals of FreeBSD, but about the practical engineering steps needed to bring up an embedded operating system where many of the key components are not yet fully mature. * Jeremy Bennett is Chief Executive of Embecosm, a company developing open source compiler tool chains and porting embedded operating systems for new architectures. He is author of the standard text book "Introduction to Compiling Techniques" (McGraw-Hill 1990, 1995, 2003) and is an active member of the RISC-V Compliance Task Group. — Buildroot for RISC-V (Using Buildroot to create embedded Linux systems for 64-bit RISC-V) Buildroot is an embedded Linux build system that generates complete system images from source for a wide range of boards and processors. I have recently added support for 64-bit RISC-V to the official Buildroot distribution which make it a viable alternative to other build systems for RISC-V such as Yocto. During this presentation I will give a brief overview of Buildroot and how it compares to Yocto for those in the audience who are unfamiliar with these systems. In the main part of the talk I will look at the issues relating to the implementation of RISC-V support, based on my experiences. This will include a look at the status of the RISC-V software ecosystem with regard to the selection of a suitable toolchain, C library, kernel and bootloader. I will then run through how to configure and build a minimal system for booting under QEMU. Finally I will consider any further work required to improve Buildroot for RISC-V including the status of 32-bit support. * Mark Corbin is Embedded Operating Systems Lead at Embecosm. He has an extensive background in embedded systems development and has worked with Linux since 1996. He specialises in building embedded Linux distributions and is currently the RISC-V maintainer for the Buildroot project. Note: Please aim to arrive by 18:15 as the event will start at 18:30 prompt. -- Andrew Back http://abopen.com

What happened to RepRap?; TFMS looking to buy Huxley Duos
by J. R. Haigh 13 Jan '19

13 Jan '19

Hi, We at the Telford Makerspace (https://TelfordMaker.space ) are looking to get 2 or 3 RepRaps (https://RepRap.org ) with which to run workshops. We decided on getting a couple of RepRap Huxley Duos (https://web.Archive.org/web/20160620213955/http://RepRapPro.com/documentati… ), and materials and parts to build at least another Huxley Duo. Features of the Huxley Duo which appeal to us are: > • OSH and well-documented; > • Cartesian-style filament printer; > • dual-filament; > • small and portable with a very sturdy frame; > • cheap – 750£ will buy at least 3 of them; > • repairable; interchangeable; modifyable; upgradable. However, Andy D'Arcy Jewell and I could not find finer details such as nozzle diameter or print resolution, and when we were looking to buy one, we found that all of the links that we tried are dead or discontinued, i.e. we could not find /any/ live link to a current retailer of the Huxley Duo. The RepRap Project somewhat feels like a ghost town. We'd like to know: • Why did RepRap Ltd. close? • What happened to the RepRap Project and its community? • Where we can get RepRap Huxley Duos and their parts from? I notice that there's a fairly recent email to the list, the one announcing the 68th OSHUG meeting, that suggests that RepRap is still current without any hint of demise: At 2018-07-10Tue21:58:59+01, Andrew Back sent: > […] > Yet engineering hasn't worked with the power of self replication much, if at all, until now. This talk will be about the RepRap Project - an open-source project that has created humanity's first general-purpose self-replicating manufacturing machine. It will examine the likely social and economic impacts of self-replicating technology, and draw parallels with a twelve-thousand-year-old industry that uses natural self-replicating machines, the industry without which we would all starve: farming. > > * Adrian Bowyer holds a first degree and a PhD in engineering from Imperial College. He was an academic engineer and mathematician at the University of Bath for 35 years, from where he retired in 2012 to become a director of RepRap Ltd., a company that sells RepRap machines and components, and that undertakes research and consultancy in RepRap-related projects. RepRap Ltd is an entirely open-source company, and all its designs, software and documentation are freely available to everyone. […] The present tense implies that RepRap is still current. I sincerely hope so. Best regards, James R. Haigh. -- Wealth doesn't bring happiness, but poverty brings sadness. https://wiki.FSFE.org/Fellows/JRHaigh Sent from NixOS with Claws Mail, using email subaddressing as an alternative to error-prone heuristical spam filtering.

Building a Crystal Set / Transistor Radio

01 Oct '18

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, @here When I was young I learned a lot from "The Boys Book of Crystal Sets" (https://www.americanradiohistory.com/Archive-Bookshelf/Technology/Boys-Book…) and the Ladybird book "Making a Transistor Radio" (https://archive.org/details/MakingATransistorRadio-LadybirdBook/page/n0). These are largely unusable today, primarily because you cannot get 500pF air spaced variable capacitors (they come up second hand on eBay sometimes at a price, but with little guarantee about actual capacitance values). Plus they are dependent on germanium technology, although that is accessible at least for the diodes. I have a 10 year old nephew who is very keen on electronics. I'd like to introduce him to the same sort of projects. Any suggestions what the modern equivalent would be?

OSHUG #69 — Members' Lightning Talks, Thurs 16th Sept.
by Andrew Back 12 Sep '18

12 Sep '18

Hi All, Registration is now open for the 69th meeting, held in partnership with the BCS OSSG, and featuring a series of member lightning talks. Details below. Cheers, Andrew // Event #69 — Members' Lightning Talks 13 September 2018, 18:30 - 20:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. http://oshug.org/event/69 We don't usually do a September meeting, but we thought it would be interesting to hear from our members about the projects that they have been working on over the year. We're delighted to welcome a range of speakers who will spend 10 or 15 minutes discussing their projects. This is a joint meeting with the British Computer Society Open Source Specialist Group. — Hammerspoon: Staggeringly powerful macOS desktop automation Hammerspoon exposes many parts of macOS to the simple scripting language Lua. Its goal is to make the most powerful and flexible tool for serious power users to automate and customise as many things as possible. In this talk we'll look at the history of automation on Apple computers, how Hammerspoon works, and some of the excellent things it can help you do. Of course, it's Open Source, so you can also jump in and help make it even better! * Chris Jones has been creating, using, and advocating for Open Source software, since the mid-1990s. He's spent the last 12 years of his professional life working on/with Open Source - the first half at Canonical (creators of Ubuntu) and since then working on OpenStack at HP and Red Hat. After 13 years of zealously running only Linux on his desktops/laptops, he has spent the last 8 years recovering as a macOS user, but has nevertheless retained his passion for contributing to Open Source. — Cooking with a touch of science and a dash of engineering. Sous vide (under vacuum) is a technique that places food into a temperature controlled water bath. The vacuum bit isn't that important, and squeezing the air out of a zip lock bag is generally sufficient; but precise temperature control is essential to ensure that the right proteins are denatured. The thermostat in a typical piece of kitchen equipment is nowhere near good enough, but add a sensor (immersible temperature gauge), an actuator (433MHz remote control socket), some control software and a dev board to run it on and you have the ability to cook perfect steaks, eggs, fish or whatever. * Chris Swan has been tinkering with electronics since he was a small child, and got into software when he realised that it was necessary to make hardware do interesting things. In his day job as CTO for Global Delivery for DXC Technology he's bringing a large services company and its customers into a world of DevOps and Infrastructure as Code. On evenings and weekends he can often be found making some sort of project around a dev board, with a particular fondness for Raspberry Pis. — Building an Open Source Electric Surfboard With the increasing availability of 3D printers and the wide variety of components available over the internet, how hard is it to build an electric surfboard? This talk will cover the design and construction of an open-source electric surfboard from the concept to hitting the sea, including some of the challenges met along the way, especially those to do with managing lots of electricity very close to lots of water. The project can be found on GitHub at https://github.com/largeostrich/openelectricsurfboard and https://github.com/largeostrich/openwaterjet. * Peter Bennett (thelargeostrich) is currently studying Mining Engineering at Camborne School of Mines, University of Exeter. He has a long standing interest in open source technology, particularly 3D printing and electronics. He previously reimagined peripherals for the EDSAC using 3D printing and arduino for ChipHack at Wuthering Bytes 2017. — Jumbo Servo - I2C position control When Andy needed a really big servo, rather than spend a fortune on an industrial monster, he decided to make one. As it would be used with a Raspberry Pi or Microcontroller he decided it would be digitally controlled rather than the usual analogue pwm. * Andy Clark has been Making and Repairing in a shed at the bottom of the garden for the last 10 years. The code and designs for his often quirky and enchanting projects can be found on GitHub and documented on the Workshopshed blog. — Next Generation Storage Interfaces The efficient, convenient, and robust execution of data-driven workflows and enhanced data management are key for productive in computer-aided RD&E. Still, the storage stack is based on the low-level POSIX I/O (or objects in cloud storage). This talk introduces chances for establishing an open community-driven next-generation storage interface in a similar fashion to the existing forums. The forum would bring together vendors, storage experts, and users to discuss key features of the API and establish governance strategies. The envisioned coarse-grained API aims to overcome current obstacles for highly parallel workflows but would be beneficial also in the domain of big data and even desktop PC. It bears the opportunity to create a new ecosystem. * Dr. Kunkel is a Lecturer at the Computer Science Department at the University of Reading. Previously, he worked as postdoc in the research department of the German Climate Computing Center (DKRZ) that partners with the Scientific Computing group at the Universität Hamburg. He manages several research projects revolving around High-Performance Computing and particularly high-performance storage. Julian became interested in the topic of HPC storage in 2003, during his studies of computer science. Besides his main goal to provide efficient and performance-portable I/O, his HPC-related interests are: data reduction techniques, performance analysis of parallel applications and parallel I/O, management of cluster systems, cost-efficiency considerations, and software engineering of scientific software. — upspin.io: a personal storage and sharing system Details TBC — A Plan 9 C Compiler for RISC-V The Plan 9 operating system was developed at Bell Labs in the 1980s using a new C compiler written by Ken Thompson, which was also later used to implement the kernel of the Inferno operating system and to bootstrap early releases of the Go language. Like Plan 9 itself, the compiler is highly portable, elegantly minimalist, lightweight and quick. The ARM version, for example, is about 21,000 lines of code and compiles itself in 15 seconds on a Raspberry Pi 3. This talk will describe the exercise of re-targeting the Plan 9 C compiler to generate code for the RISC-V open instruction set architecture. * Dr Richard Miller learned C in 1977 while re-targeting (and re-hosting) Dennis Ritchie's original Unix C compiler from the PDP-11 to the Interdata 7/32. Since then he has re-targeted Unix and Plan 9 C compilers for various other CPUs from NS 16032 to Nios II.

OSHUG #68 — 3D Printing and Making, Thurs 19th July.
by Andrew Back 10 Jul '18

10 Jul '18

Hello, Registration is now open for the 68th meeting, held in partnership with the BCS OSSG, and featuring talks on 3D Printing and Making. Details below. Cheers, Andrew // Event #68 — 3D Printing and Making 19 July 2018, 18:30 - 20:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA, (51.510812, -0.121733) http://oshug.org/event/68 At this evening meeting in London, we return to the popular themes of open source 3D printing and making. We’re delighted to welcome three leading authorities in the field to speak to us. This is a joint meeting with the UK Open Source Hardware Users Group. — Fashion Technology, Stem Cell Research & Mental Health Rachel will be talking about her personal projects in Fashion Technology and her work in stem cell research and how open source and social media communications has helped her achieve her goals. She will also touch on the importance of having a varied interest in relation to mental health. * Rachel "Konichiwakitty" Wong is a wearable tech innovator and a stem cell scientist. During the day, her PhD involves using stem cells to grow optic vesicles to study and find a cure for genetic childhood blindness. When she isn't working, she creates wearable fashion technology. She combines her skills in sewing an jewellery-making together with programming and electronics. She exhibits and gives talks on her fashion tech projects around the world to encourage young girls into STEM education and careers. She was recently awarded a Electronics Weekly BrightSparks engineering award for her work in tissue engineering and fashion technology. — Delta Printers Are Really Cool A short talk on the the ups and the many downs of delta machines, when & why you should use one, what the challenges are and a few different ways to conquer those challenges. * Bracken Dawson is a developer at IBM working on the Cloud. He was one of the five founding trustees of So Make It, the Southampton makerspace. He has been building 3D printers since the 3D printing boom in 2012. — In the future, everyone will work for 15 minutes There is much said about the coming impact on work of the robot and AI revolutions, some of it quite well-informed. But the powers of automation and intelligence are dwarfed by the power of something else: self-replication. After the fundamental forces of physics, self-replication is the most significant phenomenon that there is. Using the Sun’s energy over the last four billion years, self-replication and Darwin’s Law have created a world-surface that is knee-deep in reproducing nano-machines. Indeed, your very knees are made out of them. Yet engineering hasn't worked with the power of self replication much, if at all, until now. This talk will be about the RepRap Project - an open-source project that has created humanity's first general-purpose self-replicating manufacturing machine. It will examine the likely social and economic impacts of self-replicating technology, and draw parallels with a twelve-thousand-year-old industry that uses natural self-replicating machines, the industry without which we would all starve: farming. * Adrian Bowyer holds a first degree and a PhD in engineering from Imperial College. He was an academic engineer and mathematician at the University of Bath for 35 years, from where he retired in 2012 to become a director of RepRap Ltd., a company that sells RepRap machines and components, and that undertakes research and consultancy in RepRap-related projects. RepRap Ltd is an entirely open-source company, and all its designs, software and documentation are freely available to everyone. His areas of research are geometric modelling and geometric computing in general (he is one of the creators of the Bowyer-Watson algorithm for Voronoi diagrams), the application of computers to manufacturing, and biomimetics. He is the author of about one hundred papers and books on many different aspects of engineering, computing, mathematics and biology. Note: Please aim to arrive by 18:15 as the event will start at 18:30 prompt. -- Andrew Back http://abopen.com
