39C3: Hardware, And The Hard Bit

The 39th annual Chaos Communication Congress (39C3) is underway, and it kicked off with a talk that will resonate deeply with folks in the Hackaday universe. [Kliment] gave an impassioned invitation for everyone to start making hardware based on his experience both in the industry and in giving an intro-to-surface-mount workshop to maybe thousands of hackers over the years.

His main points are that the old “hardware is hard” cliche is overdone. Of course, working on a complicated high-reliability medical device isn’t child’s play, but that’s not where you start off. And getting started in hardware design and hobby-scale manufacture has never been easier or cheaper, and the open-source tooling gives you a foot in the door.

He tells the story of an attendee at a workshop who said “I kept waiting for the hard part to come, but then I was finished.”  Starting off with the right small-scale projects, learning a few techniques, and ramping up skills built on skills is the way to go. ([Kliment] is a big proponent of hand-placed hot-plate reflow soldering, and we concur.)

This is the talk that you want to show to your software friends who are hardware-curious. It’s also a plea for more experimentation, more prototyping, more hacking, and simply more people in the hardware / DIY electronics scene. Here at Hackaday, it’s maybe preaching to the choir, but sometimes it’s just nice to hear saying it all out loud.

Supercon 2024: From Consultant To Prototyper On A Shoestring Budget

Many engineers graduate from their studies and head out into the workforce, seeking a paycheck and a project at some existing company or other. Often, it’s not long before an experienced engineer begins to contemplate striking out on their own, working as a skilled gun-for-hire that makes their own money and their own hours.

It’s a daunting leap, but with the promise of rich rewards for those that stick the landing. That very leap is one that our own Dave Rowntree made. He came to Supercon 2024 to tell us what the journey was like, and how he wound up working on some very special shoes.

Supercon 2024: Turning Talk Into Action

Most of us have some dream project or three that we’d love to make a reality. We bring it up all the time with friends, muse on it at work, and research it during our downtime. But that’s just talk—and it doesn’t actually get the project done!

At the 2024 Hackaday Supercon, Sarah Vollmer made it clear—her presentation is about turning talk into action. It’s about how to overcome all the hurdles that get in the way of achieving your grand project, so you can actually make it a reality. It might sound like a self-help book—and it kind of is—but it’s rooted in the experience of a bonafide maker who’s been there and done that a few times over.

Supercon 2023: The Road To Writing Great Step-by-Step Instructions

IKEA is known as a purveyor of build-it-yourself flatpack furniture. LEGO is known as a purveyor of build-it-yourself toys. Both are known for their instructions. The latter’s are considered incredibly clear and useful, while the former’s are often derided as arcane and confusing—though the major difference between the two is color printing.

These two companies are great examples of why instructions are important. Indeed, Sonya Vasquez has learned this lesson well, and came down to Supercon 2023 to tell us all about it. Prepare to learn all about how to write great step-by-step instructions that enable greatness and never frustrate the end user.

Supercon 2023: Alex Lynd Explores MCUs In Infosec

The average Hackaday reader hardly needs to be reminded of the incredible potential of the modern microcontroller. While the Arduino was certainly transformative when it hit the scene, those early 8-bit MCUs were nothing compared to what’s on the market now. Multiple cores with clock speeds measured in the hundreds of megahertz, several MB of flash storage, and of course integrated WiFi capability mean today’s chips are much closer to being fully-fledged computers than their predecessors.

It’s not hard to see the impact this has had on the electronics hobby. In the early 2000s, getting your hardware project connected to the Internet was a major accomplishment that probably involved bringing some hacked home router along for the ride. But today, most would consider something like an Internet-connected remote environmental monitor to be a good starter project. Just plug in a couple I2C sensors, write a few lines of Python, and you’ve got live data pouring into a web interface that you can view on your mobile device — all for just a few bucks worth of hardware.

But just because we’re keenly aware of the benefits and capabilities of microcontrollers like the ESP32 or the Pi Pico, doesn’t mean they’ve made the same impact in other tech circles. In his talk Wireless Hacking on a $5 Budget, Alex Lynd goes over some examples of how he’s personally put these devices to work as part of his information security (infosec) research.

Remoticon 2021 // Jay Bowles Dips Into The Plasmaverse

Every hacker out there is familiar with the zaps and sizzles of the Tesla coil, or the crash and thunder of lighting strikes on our hallowed Earth. These phenomena all involve the physics of plasma, a subject near and dear to Jay Bowles’s heart. Thus, he graced Remoticon 2021 with a enlightening talk taking us on a Dip Into the Plasmaverse.

Jay’s passion for the topic is obvious, having fallen in love with high voltage physics as a teenager. He appreciated how tangible the science was, whether it’s the glow of neon lighting or the heating magic of the common microwave. His talk covers the experiments and science that he’s studied over the past 17 years and in the course of running his Plasma Channel YouTube channel.

The Ultimate Game Boy Talk

It is absolutely no exaggeration to say that [Michael Steil] gave the Ultimate Game Boy talk at the 33rd Chaos Communication Congress back in 2016. Watch it, and if you think that there’s been a better talk since then, post up in the comments and we’ll give you the hour back. (As soon as we get this time machine working…)

We were looking into the audio subsystem of the Game Boy a while back, and scouring the Internet for resources, when we ran across this talk. Not only does [Michael] do a perfect job of demonstrating the entire audio system, allowing you to write custom chiptunes at the register level if that’s your thing, but he also gets deep into the graphics engine. You’ll never look at a low-bit Pole Position clone the same again. The talk even includes some new (in 2016, anyway) hacks on the pixel pipeline in the last 15 minutes, and a quick review of the hacking tools and even the Game Boy camera.

Why do you care about the Game Boy? It’s probably the last/best 8-bit game machine that was made in mass production. You can get your hands on one, or a clone, for dirt cheap. And if you build a microcontroller-based cartridge, you can hack the whole thing non-destructively live, and in Python! Or emulate the whole shebang. Either way, when you’re done, you’ve got a portable demo of your hard work thanks to the Nintendo hardware. It makes the perfect retro project.
