by Andrew Back 01 Apr '18

01 Apr '18

Hi All, This year we will be hosting OSHCamp in the historic town of Lincoln, over the weekend of Sat 30th June & Sun 1st July. Details below. A huge thanks to Sarah Markall for volunteering to be our local expert on the ground and having arranged an excellent venue to host us. Don't delay in getting those proposals in! // -- Open Source Hardware Camp 2018 -- This year Open Source Hardware Camp will take place over the weekend of Saturday 30th June & Sunday 1st July, at the Blue Room, Lincoln, LN1 3BU. We’re excited to be hosting OSHCamp for the first time ever in the historic county town of Lincoln — home to, amongst others, noted engine builders Ruston & Hornsby (now Siemens, via GEC and English Electric). Lincoln is well served by rail, reachable from Leeds and London within 2-2.5 hours, and 4-5 hours from Edinburgh and Southampton. Proposals for talks and workshops for OSHCamp 2018 are invited! There is no theme and topics may include, for example: * Open source hardware projects * Open development practices and principles * Novel/interesting/fun projects built using open source hardware * Tools (hardware and software) * Skills and techniques, e.g. PCB fab, DIY SMT assembly * Relevant technologies, e.g. SPI/I2C bus programming * ...something else relevant to the community If you would like to give a talk on the Saturday and/or run a workshop on the Sunday, please submit details via the form at: https://docs.google.com/forms/d/1pLyItcKRDYmegNXtAXRgpt21yOFXdWlBO_K6uu0LlB… Any questions can either be directed to the list or sent to andrew(a)abopen.com. **** Note that the deadline for submitting titles and abstracts is Monday 25th March at 17:00. If you would like to discuss ideas etc. please get in touch sooner, rather than later. **** A social is planned for the Saturday evening and details of accommodation nearby to the venue will be provided in due course. // -- Andrew Back http://abopen.com

Kubernetes
by Ilya Dmitrichenko 30 Mar '18

Hi Folks, It's been a while since I posted here last time. I've not been involved with either hardware or embedded systems in general lately. I mostly work on cloud-native infrastructure, and the Kubernetes project. Kubernetes [1] is an open-source container orchestration system, and many people see it as the best abstraction and management layer for running applications in any cloud provider, and bare-metal or virtual machines. Kubernetes naturally allows clusters with any kind of hardware, as long as it can be used with Linux. In some cases certain applications benefit from certain hardware features. When user deploys an app [2] to a Kubernetes cluster, they can express an intention that certain apps have particular hardware needs, and they would do so by means of labels [3]. An example: you have some number of machines running Kubernetes. Some machines have faster storage then others, and a few have GPUs. You have apps that don't care where they run, but you also have apps that access data on disk very often, e.g. a database. You also a have apps that crunch data using GPUs. So you want to put these apps in the right places without having to care where exactly they run and get best utilisation you can out of hardware you have, in fully automated manner. Kubernetes will take care of this for you. Why could this be of interest? The most recent version of Kubernetes (v1.10) supports device plugins [4], which is a mechanism for making any kind of hardware discoverable and allocatable. If folks here are interested to hear more, I'm happy to connect in-person, or present at the meetup.

MicroZed board looking for good home
by Ilya Dmitrichenko 30 Mar '18

30 Mar '18

Hi Folks, I thought I'd post here before going to ebay. I have a brand new MicroZed board [1] that I bought a few years ago and never got a chance to use it. I'd be happy to give it to anyone interested for a reasonable offer. It's sold for $199 on avnet. I think it's still fairly modern and popular. I'm happy to take any offer from someone working on an open-source project, a student or for those who run community labs of some sort. As a bonus, I'd be happy to throw in a book by R. Sass and A. Schmidt, "Embedded Systems Design with Platform FPGAs: Principles and Practices" [2]. Which is a little older then the MicroZed board, but still is a very nice and valuable book. I've enjoyed reading it, but just don't get to do much of these things a present. I have other books I might put on Amazon, let me know if you are interested – I'd be happy for one person to take a whole package.

OSHUG 66 — Shrimping (hand-built Arduino) workshop, Thursday 19th April.
by Andrew Back 22 Mar '18

22 Mar '18

Hello, Registration is now open for the 66th meeting, a Shrimping workshop for children and adults, held in partnership with BCS OSSG. Cheers, Andrew // OSHUG #66 — Shrimping (hand-built Arduino) workshop for children and adults 19 April 2018, 18:30 - 20:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/66 The shrimp is a small Arduino compatible computer built on a breadboard. In this 1.5 hour workshop you will learn how to build and program a Shrimp, with two projects. Bring your children (7 and up) — Workshop details Project 1. Flashing LED. This project is to get you started. You will build the shrimp, and get it to flash a small LED. You will then learn how to program the shrimp to change how the LED flashes. Project 2. Persistence of vision. You will add a line of LEDs to your shrimp, and program it to flash them at very high speed, so when waved in the air it spells out a message. At the end of the workshop you can take your shrimp home with you. This workshop is suitable for anyone over the age of 7. For children 7-11, it is very much about following instructions to build a computer. For older children (our record is 92), you will start to understand how a computer works and want to explore how much it can be modified. Pre-requisits BCS Open Source SG will supply the Shrimping kits. You'll need to bring a laptop with the free Arduino IDE installed — Speaker Biographies Dr Jeremy Bennett is Chair of the BCS Open Source Specialist Group. He is also Chief Executive of Embecosm who provide open source compiler development services. A former academic he is author of the standard textbook "Introduciton to Compiling Techniques" (McGraw-Hill 1990, 1995, 2003). Note: Please aim to arrive by 18:15 as the event will start at 18:30 prompt. // -- Andrew Back http://abopen.com
