Corona Cancels Cons

March 14, 2020 by Elliot Williams 32 Comments

As you read this, the Open Hardware Summit is taking place, but differently than in previous years. This year, it’s taking place in cyberspace! To what do we owe this futuristic development? Unfortunately, COVID-19, the corona virus.

And OHS isn’t alone. Vintage Computer Festival Pacific Northwest was cancelled outright. In Germany, where I live, the national health board has recommended cancelling all events with more than 1,000 attendees, and both the Maker Faire Berlin and the Chaos Computer Club’s 20th annual Easterhegg have been called off.

And just announced yesterday, our own Hackaday Belgrade event is going to be postponed and rescheduled for later this year. It’s truly sad, but we’re still looking forward to seeing you all a little bit later in the summer. If you can’t make the new date, tickets will of course be refunded. We’ll keep you informed when we get a new venue and time.

The best way to slow the spread of a global pandemic, according to the WHO who should know best, is washing your hands and avoiding contact with other people. “Social distancing” is the new catch-phrase, and that means keeping a few meters away from other folks whenever reasonable. And clearly, gathering people from all over the world, packing them into a single auditorium, and spending quality time together doesn’t meet this requirement.

So we’re all probably going to be laying low globally for a little while. On the positive side, this means more time for hacking here in the lab, and I’m excited to be able to watch the online version of the Open Hardware Summit. If you’re working from home, it’s that much easier to keep up to date with Hackaday. Still, I can’t wait to be on the other side of this thing, and it makes me appreciate the various social gatherings that much more.

And of course I have Isaac Newton in my thoughts, who developed the groundwork for his Calculus and laws of gravitation while at home because Cambridge was closed to stop the spread of the Great Plague. Wash your hands!

Hackaday Belgrade Conference Postponed

March 13, 2020 by Elliot Williams 11 Comments

Due to uncertainties about the progress of the spread of the novel corona virus, it’s with a sad heart that we announce that we’re postponing the 2020 Hackaday Belgrade conference.

We will be rescheduling for later in the year, but for now we’ll be refunding conference tickets. We received a record number of incredible presenter proposals, and once we’ve rescheduled, we’ll get in touch with everyone who entered a proposal to check up on your availability.

In the meantime, come and hang out with us virtually on Hackaday.io’s Hackaday Belgrade page.

We know how much you were all looking forward to Belgrade in May, and it pains us to have to take this step. When we get more details ironed out, we’ll be sure to let you know! See you all a little bit later in the summer?

Welcome To The Open Hardware (Virtual) Summit

March 12, 2020 by Jenny List 6 Comments

Readers are no doubt aware of the COVID-19 pandemic and the impact it’s having on many public gatherings. Some events have been curtailed, while others have been cancelled outright. Among the events impacted is the Open Hardware Summit, which was set to kick off this Friday in New York. But all is not lost, as the decision has been made to turn it into a virtual event with with speakers delivering their talks to a live online audience.

Full refunds are available should anyone want them, but ticket holders will still receive their swag bags. The schedule for the one day event is expected to remain pretty close to the one that was already announced, and there will also be a Discord chat and #ohs2020Virtual Twitter hashtag for viewers to discuss the presentations. When it goes live, a link to watch the stream will be added to the front page of the event’s website.

With the usual schedule of hacker events stretching out across the year, it’s likely that this won’t be the only major one impacted by COVID-19. Judging by what we have heard from those event organizers among our friends, the planning required for the outbreak is causing a lot of stress on top of the usual worries inherent to the job. We’d like to ask everyone to extend their understanding to the teams behind any events that are cancelled or postponed during these exceptional times. Stay safe everyone, and enjoy the (virtual) Open Hardware Summit.

The Hacker Hotel 2020 Badge

March 12, 2020 by Jenny List 1 Comment

The art of the electronic conference badge has evolved over the last decade or more, such that for an individual example to be of note it now has to include some exceptional features. Perhaps a function that might previously have been considered impossible in a badge, or maybe an unusually beautiful design, an entertaining and compelling functionality, or it simply pushes the capabilities of an otherwise limited device in an unusually ingenious way. The badge from the recent Hacker Hotel 2020 comes from the same badge team that created the software platform derived from the SHA 2017 badge, and it ticks many of these boxes by combining a genuine work of art with a set of delightfully intricate puzzles at enough levels to interest all participants in the event.

Three Tales Of Making It In Electronics Design And Manufacturing

March 11, 2020 by Mike Szczys 4 Comments

Having found success in different areas, it’s a pleasure to hear from Erika Earl, Paul Beech, and Spencer Owen during a panel discussion at the 2019 Hackaday Superconference. Led by Tindie’s Jasmine Brackett, the panel covers some of the background needed to develop a product and get it into the hands of your customers.

Erika’s origin story begins with an interest in electronics during her teenage years that led to work in recording studios. It seems nobody on staff there was interested in repairing anything. Every company needs a hacker to make sure everything continues to work and she decided to take on the role.

From there Erika found her way into the world of manufacturing and has never looked back. You may remember hearing some of her experiences in her 2016 Hackaday Supercon talk on turning your manufacturing mistakes in a learning experience. During this panel she recounts one particularly painful experience when over-torque on a six-layer PCB damaged traces and led to extensive manual rework; always include a torque-spec!

Fear Of Potato Chips: Samy Kamkar’s Side-Channel Attack Roundup

March 9, 2020 by Dan Maloney 13 Comments

What do potato chips and lost car keys have in common? On the surface, it would seem not much, unless you somehow managed to lose your keys in a bag of chips, which would be embarrassing enough that you’d likely never speak of it. But there is a surprising link between the two, and Samy Kamkar makes the association in his newly published 2019 Superconference talk, which he called “FPGA Glitching and Side-Channel Attacks.”

Mithro Runs Down Open Source FPGA Toolchains

March 6, 2020 by Elliot Williams 28 Comments

Tim [Mithro] Ansell has a lot to tell you about the current state of open FPGA tooling: 115 slides in 25 minutes if you’re counting. His SymbiFlow project aims to be the GCC of FPGA toolchains: cross-platform, multi-platform, completely free, and all-encompassing. That means that it’s an umbrella framework for all of the work that everyone else is doing, from work on synthesis and verification tools, to placing and routing, to vendor-specific chip libraries. His talk catches you up with the state of the art at the end of 2019, and it’s embedded below. Spoiler alert: SymbiFlow has the big Xilinx 7-series FPGAs in its crosshairs, and is closing in. SymbiFlow is that close to getting a networked Linux system on the FPGA fabric in a Xilinx 7 today, completely independent of any vendor tools.

But let’s step back a sec for a little background. When you code for an FPGA, words you type get turned into a bitstream of ones and zeroes that flip perhaps a few million switches inside the chip. Going from a higher-level language to a bitstream is a lot like compiling normal programming languages, except with the twist that the resulting computational logic doesn’t map straight into a machine language, but rather into lower-level physical hardware on the FPGA. So “compilation” for FPGAs involves two steps: synthesis and place-and-routing. Synthesis takes the higher-level language that you write and turns it into a set of networks and timing requirements that represent the same logic, and can work across chip families. Yosys is the open-source synthesis tool of choice here.
