Underwater Datacenter Proves To Be A Success

September 17, 2020 by Lewin Day 65 Comments

Back in 2018, Microsoft began Project Natick, deploying a custom-designed data center to the sea floor off the coast of Scotland. Aiming to determine whether the underwater environment would bring benefits to energy efficiency, reliability, and performance, the project was spawned during ThinkWeek in 2014, an event designed to share and explore unconventional ideas.

This week, Microsoft reported that the project had been a success. The Northern Isles data center was recently lifted from the ocean floor in a day-long operation, and teams swooped in to analyse the hardware, and the results coming out of the project are surprisingly impressive.

Otis Boykin’s Precision Passives Propelled The Pacemaker

September 16, 2020 by Kristina Panos 11 Comments

The simplest ideas can be the ones that change the world. For Otis Boykin, it was a new way to make wirewound precision resistors. Just like that, he altered the course of electronics with his ideas about what a resistor could be. Now his inventions are in everything from household appliances and electronics to missile guidance computers.

While we like to geek out about developments in resistor tech, Otis’ most widely notable contribution to electronics is the control unit he designed for pacemakers, which regulate a person’s heartbeat. Pacemakers are a real-time clock for humans, and he made them more precise than ever.

Street Smarts and Book Smarts

Otis Frank Boykin was born August 29th, 1920 in Dallas, Texas to Sarah and Walter Boykin. Otis’ father was a carpenter who later became a preacher. His mother Sarah was a maid, and she died of heart failure when Otis was only a year old.

Putting The Firmware In Your Firmware

September 15, 2020 by Kerry Scharfglass 12 Comments

Performing over-the-air updates of devices in the field can be a tricky business. Reliability and recovery is of course key, but even getting the right bits to the right storage sectors can be a challenge. Recently I’ve been working on a project which called for the design of a new pathway to update some small microcontrollers which were decidedly inconvenient.

There are many pieces to a project like this; a bootloader to perform the actual updating, a robust communication protocol, recovery pathways, a file transfer mechanism, and more. What made these micros particularly inconvenient was that they weren’t network-connected themselves, but required a hop through another intermediate controller, which itself was also not connected to the network. Predictably, the otherwise simple “file transfer” step quickly ballooned out into a complex onion of tasks to complete before the rest of the project could continue. As they say, it’s micros all the way down.

SkyWater PDK Hack Chat

September 14, 2020 by Dan Maloney 8 Comments

Join us on Wednesday, September 16 at noon Pacific for the CNC on the SkyWater PDK Hack Chat with Tim “mithro” Ansell, Mohamed Kassem, and Michael Gielda!

We’ve seen incredible strides made in the last decade or so towards democratizing manufacturing. Things that it once took huge, vertically integrated industries with immense factories at their disposal are now commonly done on desktop CNC machines and 3D printers. Open-source software has harnessed the brainpower of millions of developers into tools that rival what industry uses, and oftentimes exceeds them. Using these tools and combining them with things like on-demand PCB production and contract assembly services, and you can easily turn yourself into a legit manufacturer.

This model of pushing manufacturing closer to the Regular Joe and Josephine only goes so far, though. Your designs have pretty much been restricted to chips made by one or the other big manufacturers, which means pretty much anyone else could come up with the same thing. That’s all changing now thanks to SkyWater PDK, the first manufacturable, open-source process-design kit. With the tools in the PDK, anyone can design a chip for the SkyWater foundry’s 130-nm process. And the best part? It’s free — as in beer. That’s right, you can get an open-source chip built for nothing during chip manufacturing runs that start as early as this November and go through 2021.

We’re sure this news will stir a bunch of questions, so Tim Ansell, a software engineer at Google who goes by the handle “mithro” will drop by the Hack Chat to discuss the particulars. He’ll be joined by Mohamed Kassem, CTO and co-founder of efabless.com, and Michael Gielda, VP of Business Development at Antmicro. Together they’ll field your questions about this exciting development, and they’ll walk us through just what it takes to turn your vision into silicon.

Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, September 16 at 12:00 PM Pacific time. If time zones baffle you as much as us, we have a handy time zone converter.

Click that speech bubble to the right, and you’ll be taken directly to the Hack Chat group on Hackaday.io. You don’t have to wait until Wednesday; join whenever you want and you can see what the community is talking about.

Finalists Announced For The 2020 Hackaday Prize

September 14, 2020 by Tom Nardi 8 Comments

In light of everything going on in 2020, the 7th annual Hackaday Prize is devoted to nurturing ideas that could literally help change the world. In a first, we partnered with several nonprofits to help identify some of today’s most difficult problems, ranging from conservation and disaster relief to the need for advanced assistive technology. With over $200,000 up for grabs, including microgrants to help teams work full-time on their projects, this year’s competition was designed to help bring critical solutions to fruition which otherwise might never see the light of day.

But it hasn’t been easy. The global pandemic has made it far more difficult to collaborate on projects in the way we’re all used to, parts have become harder to source, and many makers found themselves so engaged with grassroots efforts to combat COVID-19 that they found little time for anything else. But despite all of this uncertainty, we received hundreds of incredible entries from all over the globe.

It’s never easy to select who will move on to the next round of the competition. But with the help of our nonprofit partners, the panel of expert judges was able to whittle the list of entries down to the 34 finalists that produced some of the most impressive and impactful ideas the Hackaday Prize has ever seen. Let’s take a look at just a few of the projects that will be vying for the top prizes in November.

Hackaday Links: September 13, 2020

September 13, 2020 by Dan Maloney 7 Comments

Like pretty much every other big conference, the Chaos Communication Conference is going virtual this year. What was supposed to be 37C3 has been rebranded as rC3, the remote Chaos Experience. It’s understandable, as a 17,000 person live event would have not only been illegal but a bit irresponsible in the current environment. The event appears to be a hybrid of small local events hosted in hackerspaces linked with streamed talks and a program of workshops and “online togetherness.” rC3 is slated to run in the week between Christmas and New Year, and it seems like a great way to wrap up 2020.

Speaking of remote conferences, don’t forget about our own Remoticon. While it won’t be quite the same as everyone getting together in sunny — historically, at least — Pasadena for a weekend of actual togetherness, it’s still going to be a great time. The event runs November 6 to 8; we’ve had a sneak peek at the list of proposed workshops and there’s some really cool stuff. Prepare to be dazzled, and make sure you keep up on the Remoticon announcements — you really don’t want to miss this.
