spare dev boards
by Ilya Dmitrichenko 16 Mar '21

16 Mar '21

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

If the hardware is owned by them and they are waiting to receive it back from you it sounds like it might not be great legally. -- Stuart Clark

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

19 Feb '21

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

JTAG options
by Sevan Janiyan 18 Feb '21

18 Feb '21

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

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

16 Jul '20

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

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

02 Jul '20

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

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

15 Apr '20

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