Superconference Interview: Sam Zeloof

November 12, 2019 by Lewin Day 2 Comments

In less than four days, the fifth Hackaday Superconference kicks off in Pasadena, California, and it’s shaping up to be a hoot. With a cavalcade of exciting workshops and talks on offer, hackers and makers are pouring in from across the globe for this celebration of software, firmware, and hardware.

Of course, the real gift of Supercon is the personalities which make up this awesome community. [Sam Zeloof] is one such luminary, well known for producing his very own silicon integrated circuits in his parent’s garage. Not content to keep this knowledge to himself, [Sam] gave an amazing talk at the 2018 Supercon on just what goes into creating your own silicon fab on a budget.

Our very own [Mike Szczys] caught up with [Sam] for an interview, discussing being inspired by the work of [Jeri Ellsworth], as well as the finer points of getting into lithography at home. [Sam] will be in attendance at the 2019 Superconference, of course. While he won’t be on the speaking circuit this year, his brother [Adam] will be presenting a talk called Thermodynamics for Electrical Engineers: Why Did My Board Melt (And How Can I Prevent It)?, which is sure to be a must-see.

You really should be there, but alas tickets have been sold out for almost two months! Never fear, we’ll be livestreaming the event. Be sure to subscribe to Hackaday on Youtube to be notified when it all kicks off, around 10 AM Pacific Time on Saturday, November 16th. If you scored tickets and are heading to Supercon, we can’t wait to see you there — the badge hacking begins early Friday morning.

Be sure to check out Sam’s interview after the break!

Found Footage: Elliot Williams Talks Nexus Technologies

November 7, 2019 by Tom Nardi 25 Comments

Back at the 2017 Superconference, Hackaday Managing Editor Elliot Williams started his talk about the so-called “Internet of Things” by explaining the only part he doesn’t like about the idea is the Internet… and the things. It’s a statement that most of us would still agree with today. If anything, the situation has gotten worse in the intervening years. Commercial smart gadgets are now cheaper and more plentiful than they’ve ever been, but it seems like precious little has been done to improve their inherent privacy and security issues.

But his talk doesn’t serve to bash the companies producing these devices or even the services that ultimately folded and left their customers with neigh useless gadgets. That’s not his style. The central theme of “Nexus Technologies: Or How I Learned to Love WiFi” is that a smart home can be wonderful thing, assuming it works the way you want it to. Elliot argues that between low-cost modular hardware and open source software, the average hacker has everything they need to build their own self-contained home automation ecosystem. One that’s not only cheaper than what they’re selling at the Big Box electronics store, but also doesn’t invite any of the corporate giants to the party.

Of course, it wasn’t always so. A decade ago it would have been all but impossible, and five years ago it would have been too expensive to be practical. As Elliot details his journey towards a truly personal smart home, he explains the advances in hardware and software that have made it not just possible on the DIY level, but approachable. The real takeaway is that once more people realize how cheap and easy it is to roll your own smart home gadgets, they may end up more than willing to kick Big Brother to the curb and do IoT on their own terms.

This previously unpublished recording somehow slipped between the cracks of the editing room floor but upon recent discovery, it’s still just as relevant today. Take a look at Elliot’s view on Nexus Technologies, then join us after the break for a deeper dive. Make sure to subscribe to Hackaday’s YouTube channel to get in on the 2019 Hackaday Superconference live stream starting Saturday, November 16th.

Supercon Keynote: Dr. Megan Wachs On RISC-V

November 6, 2019 by Elliot Williams 28 Comments

Hackaday has open-source running deep in our veins — and that goes for hardware as well as software. After all, it’s great to run open-source software, but if it’s running on black-box hardware, the system is only half open. While software has benefited mightily from all of the advantages of community development, the hardware world has been only recently catching up. And so we’ve been following the RISC-V open-source CPU development with our full attention.

Our keynote speaker for the 2019 Hackaday Superconference is Dr. Megan Wachs, the VP of Engineering at SiFive, the company founded by the creators of the RISC-V instruction-set architecture (ISA). She has also chaired the RISC-V Foundation Debug Task Group, so it’s safe to say that she knows RISC-V inside and out. If there’s one talk we’d like to hear on the past, present, and future of the architecture, this is it.

The RISC-V isn’t a particular chip, but rather it’s a design for how a CPU works, and a standard for the lowest-level language that the machine speaks. In contrast to proprietary CPUs, RISC-V CPUs from disparate vendors can all use the same software tools, unifying and opening their development. Moreover, open hardware implementations for the silicon itself mean that new players can enter the space more easily, bring their unique ideas to life faster, and we’ll all benefit. We can all work together.

It’s no coincidence that this year’s Supercon badge has two RISC-V cores running in its FPGA fabric. When we went shopping around for an open CPU core design, we had a few complete RISC-V systems to pick from, full compiler and development toolchains to write code for them, and of course, implementations in Verilog ready to flash into the FPGA. The rich, open ecosystem around RISC-V made it a no-brainer for us, just as it does for companies making neural-network peripherals or even commodity microcontrollers. You’ll be seeing a lot more RISC-V systems in the near future, on your workbench and in your pocket.

We’re tremendously excited to hear more about the project from the inside, and absolutely looking forward to Megan’s keynote speech!

The Hackaday Superconference is completely sold out, but that doesn’t mean that you have to miss out. We’ll be live-streaming the keynote and all other talks on the Supercon main stage, so subscribe our YouTube channel and you won’t miss a thing.

Superconference Interview: Carl Bugeja

November 5, 2019 by Jenny List 1 Comment

It’s an exciting time of year for us, not because Christmas is on the horizon, instead for something far more exciting than that! The Hackaday Superconference is nearly upon us, our yearly gathering of the creme de la creme of the hardware hacking world for a fascinating program of lectures and other events. We can’t wait, and we hope you’re looking forward to it as much as we are.

A particularly stimulating part of the Supercon experience comes from the people you rub shoulders with as you attend, whether or not you will have seen their work on these pages they represent a huge and fascinating breadth of experience and skill. It’s the incidental conversations at events like this that are the most fertile, because from them comes inspiration that can feed all manner of things.

One of last year’s hits came from Carl Bugeja, when he gave a talk about his impressive work with using printed circuit boards to construct electric motors and magnetic actuators. We’ve seen the various iterations of his work evolving in these pages, and at last year’s event he also gave an interview to our own Elliot Williams, and we’re happy to bring you the resulting video after the break.

We’d love to be able to reveal a hidden stash of Supercon tickets, but sadly it’s all sold out. We can however direct you to the livestream of the event which begins at 10 am Pacific time on November 15th. Be sure to head on over to the Hackaday YouTube channel, and subscribe.

Meanwhile it’s worth pointing those lucky ticket holders to the Supercon ticketing page since we’ve added more tickets to the previously-sold-out workshops. Now, enjoy Carl’s interview, and we hope you’ll join us for Superconference whether you do so online or in person.

Gigantic FPGA In A Game Boy Form Factor, 2019 Supercon Badge Is A Hardware Siren Song

November 4, 2019 by Mike Szczys 54 Comments

Look upon this conference badge and kiss your free time goodbye. The 2019 Hackaday Superconference badge is an ECP5 FPGA running a RISC-V core in a Game Boy form factor complete with cartridge slot that is more open than anything we’ve ever seen before: multiple open-source CPU designs were embedded in an open system, developed using the cutting-edge in open-source FPGA tools, and running (naturally) open-source software on top. It’s a 3,000-in-one activity kit for hardware people, software people, and everyone in between.

The brainchild of Jeroen Domburg (aka Sprite_TM), this design has been in the works since the beginning of this year. For more than 500 people headed to Supercon next week, this is a source of both geeky entertainment and learning for three action-packed days and well beyond. Let’s take a look at what’s on the badge, what you need to know to hack it, and how the design serves as a powerful development tool long after the badge hacking ceremonies have wrapped up.

Eth0 Autumn 2019: Tiny Camp, Creative Badge

November 3, 2019 by Jenny List 12 Comments

The Dutch organisation eth0 has run a series of informal small camps over the years, never with an attendance too far into three figures, and without pre-planned events or entertainment. What happens is at the instigation of the attendees, and the result is a weekend of much closer socialising and working together on projects than the large camps where you spend your time running around to catch everything.

The largest of hacker camps offer all the lights, robots, tschunk, and techno music you can stomach; they can be a blast but also overwhelming. I made my way eth0 over the past week weekend, enjoying the more intimate size and coming away having made friendships from spending time with great people at a large private camping hostel near Lichtenvoorde. This is in the far east of the country near the German border, to which in the company of a British hardware hacker friend I traveled in the tiny European hatchback. Netherlands roads are so easy to navigate!

At the event was the usual array of activities, though since it was a restricted photography affair I’m short on wider shots that would include people. This year’s hit came from surplus flipdot displays from retired German buses, with plenty of glitches as their quirks were figured out by our friends Lucy Fauth and Jana Marie Hemsing. Something tells me I’ll be seeing a lot of those fluorescent circles in the future.

I’d brought along the nucleus of a textile village, and RevSpace in the Hague had added their embroidery machine to my overlocker and sewing machines. Its operator was Boekenwuurm from Hackalot in Eindhoven who was kind enough to embroider a Wrencher for me, and now I want one of these 600-Euro machines even if I can’t afford one. She and RevSpace’s Igor Nikolic were experimenting with inflatables and tensegrity structures, creating prototypes with an eye to more impressive installations at future camps.

An entertaining tale of a couple of days hanging out with friends in the Netherlands countryside could probably be spun into a reasonable tale, but there was something more interesting still at this camp. It had a badge, courtesy of the prolific badge.team Dutch badge crew. It didn’t come with their trademark ESP32 firmware though, instead in keeping with the budget of the event it was a prototyping board on which attendees could create their own badges. What came forth from that was extremely impressive, and continued after the event.

The 3D Printers, Scanners, And Art Robots Of Maker Faire Rome

November 2, 2019 by Mike Szczys 7 Comments

How is it possible that a robot can sketch both better and worse than I can at the same time, and yet turn out an incredible work of art? Has 3D-scanning really come so far that a simple camera and motorized jig can have insane resolution? These are the kinds of questions that were running through my mind, and being answered by the creators of these brilliant machines, at Maker Faire Rome.

There was a high concentration of robots creating art and 3D printing on display and the Faire, so I saved the best examples just for this article. But you’ll also find hacks from a few groups of clever students, and hardware that made me realize industrial controllers can be anything but boring. Let’s take a look!
