Boldport Club, PCBmodE, and OSHW
by Saar Drimer 24 Feb '16

24 Feb '16

Hello OSHUG friends, Recently I've launched a new service that I'm really excited about. It's called the Boldport Club. When you become a member you get a monthly delivery of 'electronics goodness' projects that we designed https://boldport.cratejoy.com Most of you know that I specialise in circuits that emphasize usability and that have unique visuals. I do this with PCBmodE, an open source software that I've written specifically for this purpose http://pcbmode.com Unless a client is unwilling, all of the boards that I design are also open source. This means that by signing up to the Boldport Club, you're not only getting unique items, you are also supporting the further development of PCBmodE. If Jeremy hasn't already shown it to you (HA!), this is a board that he commissioned from Boldport last year through Embecosm http://boldport.com/seahorse Another project I'm quite proud of is Haute Circuits, which appeared in the December issue of Marie Claire magazine US http://boldport.com/hautecircuits If you sign up to the Boldport Club or don't, please provide me with feedback so that I can learn how to go about it better. Many thanks and have a great week ahead, Saar. Dr Saar Drimer Electronics craftsman and founder at Boldport +44(0)7779606045 http://bolsport.com

OSHUG #46 — Embedded Platforms, Thursday 17th March.
by Andrew Back 19 Feb '16

19 Feb '16

Hello, Registration is now open for the March meeting, details of which can be found below. Cheers, Andrew // Event #46 — Embedded Platforms (BSD, OpenWRT, Plan 9 & Inferno) On the 17 March 2016, 18:00 - 20:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/46 The forty-sixth OSHUG meeting will take a look at embedded platforms, with talks on the BSD family of operating systems, Linux and OpenWRT, and Plan 9 and Inferno in distributed systems. — The BSD Family of Operating Systems A familiar environment for your VAX, PIC32 or RISC-V ISA and many other platforms. The Berkeley Software Distribution started out as a patch set to AT&T UNIX in the 70's and grew to a complete Operating Systems. Today several projects continue to develop variant operating systems based on the work originally started by the Computer Science Research Group, each with a different area of focus. This presentation will cover some of the benefits these operating systems can offer to aid the workflow of a hardware project. Sevan Janiyan is founder of Venture 37, which provides system administration & consultancy services. As a fan of operating systems and computers with different CPU architectures, in his spare time he maintains builds of open source software on a variety of systems featuring PowerPC, SPARC and armv7l CPUs. He hopes to own a NeXTcube & OMRON LUNA-88K2 one day. — Developing Linux based products in the connected devices ecosystem -- The OpenWRT Approach Linux is accepted as a standard component of the Internet of Things domain. With the abundance of development platforms and the abhorrent state of vendor provided SDKs, getting started with and more importantly the maintenance of Linux powered devices is pretty much a dark art these days. This talk focuses on the mass market hardware platforms of interest to folks building the Next Great IoT ProductTM and how the development could be sped up with OpenWRT. To supplement the topic of product development, a couple of noteworthy System-on-Chip devices and how they could be adopted will also be discussed. Ivan Iacono is an Embedded Systems Engineer interested in the development of Linux based products and the surrounding periphery of embedded devices, cloud and the overall architecture of connected systems. He is the Firmware Wrangler at Den Automation. Omer Kilic is an Embedded Systems Engineer who likes tinkering with small computers of all shapes and sizes. He works at the various intersections of hardware and software engineering practices, product development and manufacturing. He is the Chief Hacker at Den Automation. — Embedded devices are often now part of a distributed system: my Pebble watch is linked to my Nexus phone, which is coupled to Google. Plan 9 and Inferno are two distributed systems originally developed by the Bell Labs research centre that produced Unix. They allow a single large system to be composed from smaller cooperating systems performing specific tasks. (In other areas they illustrate an alternative time line that diverged from strict adherence to Unix's details of the 1970's.) Distributed systems infrastructure often focuses on algorithmic aspects, such as Paxos, and the operating system is largely irrelevant when it is not merely obstructive. Plan 9 and Inferno provide structural support for distribution, at the operating system level. Their defining novelty is the representation of all distributable resources as hierarchical name spaces, which can be composed in useful ways, and simplify design, development, testing and integration. This talk will give a brief summary of both systems, then begin to name names, including their use in embedded appliances in distributed systems. 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. Note: Please aim to arrive by 18:15 as the event will start at 18:30 prompt.

OSHUG #44 — Open Energy Tools & Interoperability.
by Andrew Back 29 Jan '16

29 Jan '16

Hello, Registration is now open for the February meeting — and preceding hack day! — details of which can be found below. Cheers, Andrew // Event #45 — Open Energy Tools & Interoperability (Open Inverter, OpenTRV, Heat Pump Monitoring) On the 18 February 2016, 18:00 - 20:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/45 For the forty-fifth meeting we will return to a topic which has been a recurring theme and of much interest at previous meetings, open energy platforms. There will be talks on Open Inverter, OpenTRV and heat pump monitoring, with a focus also on interoperability. The evening meeting will also be preceded by an interoperability hack day for project contributors. — Low power DC conversion using open source hardware The Open Inverter is a micro inverter designed to produce an AC power output of up to 250 VA. It uses modular, open source PCB designs for both it's controller and power boards — and is extendible to larger power outputs or for other power electronics projects, such as battery charging, DC ring mains and DC power transformation using buck-boost DC/DC converters. Open Inverter will provide an AC output from a single 250W photovoltaic panel, micro-hydro turbine. It also has applications in electric bike charging and DC power storage. The key PCBs are currently at either the layout or manufacture stage. The microcontroller board features an RFM69 low power wireless, making it compatible with the Open Energy Monitor ecosystem. Ken Boak started his professional career at BBC Research Department in 1986 working on digital signal processing systems for HDTV and subsequently over 30 years, a mix of 10 other technology companies, both UK and US based, in the fields of instrumentation, automation, telemetry telecomms. Ken has been interested in energy monitoring since the early 1990s, when he constructed a 4 seater electric car, and provided rudimentary energy analysis of the battery charge and discharge cycles. In 1998 he joined a South London company and designed a low power wireless, monitor device for automatic, remote gas and electricity meter reading. In 2009 Ken worked on the Onzo Energy Monitoring Kit, a commercial device that was ultimately distributed to Southern Electric customers. Then in 2010 he produced a series of educational devices to teach engineering undergraduates the principles of photovoltaic energy systems. Ken has continued his interests in energy monitoring, working collaboratively with Megni on the OpenEnergyMonitor project, the open Inverter Project and also for All Power Labs in Berkeley, California, where he was involved in power monitoring of wood gasifier generator sets. He tries to live a low impact lifestyle in a modest Edwardian house in Surrey, with a little help from modern electronics. — OpenTRV OpenTRV have a vision to make carbon cutting and energy saving easy and cheap for everyone, with a mission to take 8% out of the EU’s carbon emissions and in the order of £300 out of a typical UK home’s heating bill every year. Achieving this using a device that doesn’t need an instruction manual or a smartphone to operate. OpenTRV aim to eventually be managing 400 million home radiators across Europe. Their journey so far has taken them from “scratching an itch” with open source, to injection moulded plastics being made in Shenzhen, and attempting to build a growth business around their ideas, that could really make a difference to carbon and climate, while improving householder comfort and health. As part of their aim to make the world a better place, OpenTRV will keep as much as possible of their work in the public eye and liberally licensed, while interoperating with existing equipment and protocols so that there is no need to reinvent the wheel and the end user doesn’t get “locked in”. To that end, interoperability with OpenergyMonitor and OpenHAB are high on their wish list! Damon Hart-Davis is lead on the OpenTRV open source project created following his 2012 presentation to DECC's smart heating workshop. He has freelanced in technology for over 30 years, delivering mission-critical products from design to BAU in the City for more than 20 of those, and has founded and been involved in several start-ups over that time with his creations seen on TV, the Web, and his pioneering Internet Service Provider helping crack open that market more than 20 years ago. A previous virtual/on-line credit-card company start-up that he co-founded as CTO, Ixaris, turns over ~£10m. Mark Hill spent 15 years in the City after a solid grounding in IT at the chip level at the microprocessor manufacturer Inmos, designing and delivering highly complex systems. Project management, direction and governance are all part of his toolkit. He now speaks regularly about innovation, collaboration and IoT. Recently he founded a mobile phone software start-up and is now OpenTRV Ltd's co-founder. — Heat pumps and heat pump monitoring Heat pumps are a key part of zero carbon energy plans, making it possible to provide heating from renewable energy in an efficient way. Heat pumps have a rocky track record in the UK and there are numerous stories of poorly performing systems, giving householders unexpectedly high electricity bills. However, there are also many systems that have been designed and installed well that do work effectively. This talk will give an example of using open source hardware and software tools to monitor and evaluate the performance of heat pumps, using the speaker's own air source heat pump system at home as a case study. Trystan Lea is co-founder and core developer on the OpenEnergyMonitor project. He is also testing out through his own life how it is possible to provide for our energy needs from sustainable sources, while using and developing open source energy modelling and monitoring tools, to understand and evaluate what is possible and how we might better design zero carbon energy systems. Trystan is currently testing heat pump heating, along with electric vehicle and solar photovoltaic at home. — Interoperability Hack Day The 18th February meeting will be preceded by a hack day, running from 09:00-17:00 and also hosted at the BCS offices in Covent Garden. This will aim to to foster collaboration between open energy platform projects, in support of a greater interoperability. There is a separate registration page for this part of the day, but please note that participants are expected to have experience of developing for a relevant platform, such as OpenEnergyMonitor, OpenHAB, OpenTRV, or some other open source energy or home automation etc. system. As such hose without suitable experience would not benefit from attending. https://events.bcs.org/book/1886/ Please note that the link at the top of the page should be used for registering for the evening talks.

OSHCamp 2016, 3rd & 4th September.
by Andrew Back 25 Jan '16

25 Jan '16

Hi All, Just a heads up that this year Open Source Hardware Camp will be taking place over the weekend of Saturday 3rd and Sunday 4th September, returning to the Birchliffe Centre where we hosted OSHCamp back in 2012. Since we were last there the Birchcliffe has been subject to extensive renovation, but still retains most of the pretty cool features of an old Methodist Chapel. The main differences being that it's been smartened up somewhat, is in a much better state of repair and has more effective heating etc. Those who came along in 2012 may recall that there is a hostel adjoined to the Birchcliffe, with both shared dorms and private rooms. If you're thinking of coming along this year and would like to stay there, it's advisable to book early as rooms tend to go fast. http://www.hebdenbridgehostel.co.uk/ The plan is once again to have up to 12-13 talks on the Saturday and 6-8 workshops on the Sunday. A call for participation will go out in Feb or early March, but suggestions and offers for talks and workshops are very much welcome before then! Other events running as part of Wuthering Bytes which may be of interest: - Wuthering Bytes Festival Day, Fri 2nd Sept at the Town Hall As with previous years, talks on a diverse selection of technical topics, looking to the past and the future, with unique insights and personal journeys etc. - Open for Business, Mon 5th Sept at the Town Hall This event organised by the BCS OSSG and Open Source Consortium ran for the first time in 2015. For details see: http://wutheringbytes.com/days/openforbusiness/schedule.html https://www.youtube.com/playlist?list=PLOGTP9W1DX5U9za_jJzqpipcX02-K7jp1 - GNU Tools Cauldron, Fri 9th - Sun 11th Sept at the Town Hall One really for GCC and GDB etc. hackers (and certainly not the faint hearted!) For details see: https://gcc.gnu.org/wiki/cauldron2016 Cheers, Andrew

Re: [oshug] "The audio genius who vanished"
by Jason Flynn G7OCD 17 Jan '16

17 Jan '16

I'm going to stick my neck out here as someone who regularly makes NC and ND contribution to the community. It's unhelpful and unpleasant having people class your work as second class because of some other peoples' arbitrary redefinition of the word open. There are a lot of greedy and selfish people out there and my efforts to put my works in the public domain are for then general good and not to fuel such people who offer nothing to society in return. It doesn't mean that my efforts can never be moved forward or turned to profit but it does allow me to vet the intentions of those that I let do so.

OSHUG #44 — Security, Thursday 21st January.
by Andrew Back 12 Jan '16

12 Jan '16

Hello, Registration is now open for the January meeting, details of which can be found below. Cheers, Andrew // Event #44 — Security (Hardware RNG, PGP key signing party) On the 21 January 2016, 17:30 - 20:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/44 The theme for the forty-fourth OSHUG meeting is security and it will feature a talk on hardware random number generation, plus a PGP key signing party. — Hardware random number generation In this talk we will take a look at what makes a good random number, why you might want a reliable source of them and some methods of generating random numbers in hardware. Mark Longstaff-Tyrell has a degree in Electronic Engineering and a masters in Intelligent Systems from UCL. He has extensive experience in app development and as well as working at several blue chip companies was part of the team that launched the BBC's flagship iPlayer app for Android in addition to leading the teams that delivered the mobile apps for BBC News. He has designed electronics kits under the Denkimono label, and has recently co-founded and launched a tech-fashion brand in the UK. Mark is also a consultant for small businesses and start-ups on apps, mobile and hardware development. — PGP key signing party There will be a quick introduction to PGP, The Web of Trust, public/private key cryptography and key signing. Following this there will be a key signing party and everyone is invited to participate! The idea of a key signing party is to help build and strengthen the "Web of Trust". The PGP Web of Trust is used extensively in Free and Open Source communities in order to verify the authenticity of software distributions and e-mail. Participating in the Web of Trust by having your key signed and by signing other keys, establishes your identity as a member of the community and increases the likelihood that you will be able to verify the signatures that are often included on messages sent to mailing lists. In order to take part in the key signing party you need to: 1. Have a PGP key. If you do not have one already and need assistance, please e-mail Andy Bennett (a(a)jpb.li) and he will help you get started. 2. Submit your key to Andy Bennett (a(a)jpb.li) before Friday 15th January 2016, so that he can compile the key list. 3. Be physically present at this meeting! 4. For keys containing your real name, bring government issued photo ID. For pseudonymous keys please bring appropriate evidence that you are allowed to use that name and assert that identity. 5. Have details of the key you submitted: key ID, key type, key fingerprint and key size. You can get this information from GPG by using the following command: gpg your.email(a)address.dom. 6. Bring a printed copy of the key list that will be circulated between 16th and 20th January. Note: Please aim to arrive by 18:15 as the event will start at 18:30 prompt.
