Hackaday Superconference 2023: Workshops Announced, Get Tickets Now!

October 12, 2023 by Elliot Williams 4 Comments

Last week, we announced just half of our fantastic slate of talks for Supercon. This week, we’re opening up the workshops. The workshops are small, hands-on opportunities to build something or learn something, lead by an expert in the field. Workshops sell out fast, so register now if you’re interested.

And stay tuned for the next round of talk reveals next week! And maybe even the badge reveal?

Andy Geppert
Weave Your Own Core Memory – Core16!

This workshop provides you with the opportunity to weave your own core memory! Using 16 authentic ferrite core bits and 16 RGB LEDs, you can play tic-tac-toe, paint with a magnetic stylus, and create your own interactive experiences. Andy Geppert will guide you through the assembly of Core16. The Core16 kit is the little brother of the Core64 kit. The smaller Core16 kit reduces assembly time/cost, enabling more people to experience the challenge and satisfaction of creating their own core memory.

Travis Foss
Presented by DigiKey: Introduction and expansion of the XRP Robotics Platform

In this workshop you will be able to get your hands on the new XRP (Experiential Robotics Platform) and take the basics a step further with a few additional parts. Along with the base kit, participants will have the opportunity to install a RGB twist encoder, a LCD screen, and a buzzer to create a setup that will allow the user to choose a program onboard without being tethered to a computer.

Becky Button
How to Make a Custom Guitar Pedal

Musical effects are for everybody! Join this workshop and get hands-on experience assembling and programming your musical effects pedals. Walk away from this workshop with the capability of integrating multiple musical effects into 1 device and reprogramming the pedal with any effects you want!

Daniel Lindmark
From Zero to Git: 1 Hour Hardware Git Bootcamp

In this workshop, you will learn all about basic git operations, including how to download and install the client, setting up a repo, synching changes, and much more. Learn how to navigate common issues and take advantage of a live FAQ during the workshop.

Jazmin Hernandez
Solder and Learn How to Use Your Own Anti-Skimmer (HunterCat)

Have you ever been vulnerable to data theft? Do you fear using your bank card in ATMs or even in a restaurant? Protect your information from potential skimmers in this workshop while you learn to solder some components of your anti-skimmer/magnetic stripe clone detectors. By the end of the workshop, you’ll have a device to insert before using your bank card to check for potential issues.

Matt Venn
Tiny Tapeout – Demystifying Microchip Design and Manufacture

In this workshop, you can design and manufacture your own chip on an ASIC. You will learn the basics of digital logic, how semiconductors are made, the skills needed to use an online digital design tool for simulation, and how to create the GDS file for manufacturing. Participants will also have the option to submit their designs to be manufactured as part of the Tiny Tapeout project.

You can’t attend the workshops without attending Supercon, so get your tickets! (As we write, there are only ten more…)

Supercon 2022: [Alex Whittemore] On Treating Your Sensor Data Well

September 15, 2023 by Arya Voronova 4 Comments

If you build your own devices or hack on devices that someone else has built, you know the feeling of opening a serial terminal and seeing a stream of sensor data coming from your device. However, looking at scrolling numbers gets old fast, and you will soon want to visualize them and store them – which is why experienced makers tend to have a few graph-drawing and data-collecting tools handy, ready to be plugged in and launched at a moment’s notice. Well, if you don’t yet have such a tool in your arsenal, listen to this 16-minute talk by [Alex Whittemore] to learn about a whole bunch of options you might not even know you had!

For a start, there’s the Arduino Serial Plotter that you get for free with your Arduino IDE install, but [Alex] also reminds us of the Mu editor’s serial plotter – about the same in terms of features, but indisputably an upgrade in terms of UX. It’s not the only plotter in town, either – Better Serial Plotter is a wonderful standalone option, with a few features that supercharge it, as [Alex] demonstrates! You don’t have to stop here, however – we can’t always be tethered to our devices’ debugging ports, after all. Continue reading “Supercon 2022: [Alex Whittemore] On Treating Your Sensor Data Well” →

To Give Is Better Than To Receive

September 2, 2023 by Elliot Williams 24 Comments

Better to give a talk at a hacker event, that is. Or in your hackerspace, or even just to a bunch of fellow nerds whenever you can. When you give the talk, don’t be afraid to make it too “easy” to understand. Making a tough topic comprehensible is often the sign that you really understand it, after all, and it’s also a fantastic service to the audience. And also don’t be afraid that your talk isn’t “hard core” enough, because with a diverse enough crowd, there will absolutely be folks for whom it’s still entirely new, and they’ll be thankful.

These were the conclusions I got from talking to a whole range of people at Chaos Communication Camp the weekend before last, and it’s one of the great opportunities when you go to an event like this. At Camp, there were a number of simultaneous stages, and with so many talks that new ones are still being released. That meant that everyone had their chance to say their bit, and many many did.

And that’s great. Because it’s obvious that getting the work done, or diving deep into a particular topic, is part of the hacker experience, but it’s also equally important to share what you’ve gained with the rest of the community. The principle of spreading the knowledge is a cornerstone of our culture, and getting people up to talk about what they’ve learned is the manifestation of this cultural value. If you know something, say something!

Of course, when you’re not at a conference, you could be writing up your hacks and sending them in to the tips line (hint, hint!). That’ll work too.

Maker Faire Hannover: The Right Way To Do It

August 28, 2023 by Jenny List 16 Comments

On these pages we bring you plenty of reports from events, most of which are from the hacker or hardware communities. These can be great fun to attend, but they’re not the only game in town when looking at things adjacent to our community. At what you might describe as the consumer end of the market there are the Maker Faires, which bring a much more commercial approach to a tech event. While so many of us are in Germany for Chaos Communication Camp there’s a maker faire ideally placed to drop in on the way back. We took the trip to Hannover, a large and rather pleasant city just off the Berlin to Amsterdam motorway roughly central to the top half of the country. It’s got one of the German emissions zones so without the green tax sticker in the car we took a park-and-ride on one of their clean and efficient trams to alight a short walk from the congress centre.

How Do They Do That?

August 26, 2023 by Elliot Williams 20 Comments

Last week’s Chaos Communication Camp is kinda a big deal: 6,000 hackers all out in a field all need power, food, drink, networking, and of course, sewage in the middle of nowhere. Oh yeah, plus video services on multiple simultaneous stages, custom phone infrastructure, a postal service, and even a diesel train. How is that even possible to run with only volunteers? How do they even know how to run something this scale?

My wife asked me this question while we were driving up to Berlin, and the answer is of course the same as it is to “Excuse me, can you tell me how to get to Carnegie Hall?” Practice.

But it’s not just practice. It’s also passing down the lessons learned to the next generation, making procedures that are not 100% dependent on the people doing the jobs, but can be passed on to the next volunteer willing to pick up the torch.

And then I was interviewing [Jens Ohlig] and [Mitch Altman] about the early days of the second wave hackerspaces in America for the podcast. (Some great interviews – go check it out!) The central story there is essentially the same: the critical missing ingredient that lead to the blossoming of US hackerspaces was simply a set of instructions and design principles – drawing on the experience of established hackerspaces.

Sharing information is a fundamental cornerstone of the hacker ethic, and it gives the next hacker a leg up. Contributes to the global hive mind. And it makes things possible that would otherwise seem impossible. Pushing the hacker state-of-the-art is what Hackaday is all about, and we’re used to thinking of it in terms of a particular microcontroller library, but seeing how the same sharing makes impossible logistics possible was inspirational. Don’t be afraid to start small and iterate – and take good notes.

Privacy And Photography, We Need To Talk

August 25, 2023 by Jenny List 41 Comments

One of the fun aspects of our global community is that there are plenty of events at which we can meet up, hang out, and do cool stuff together. They may be in a Las Vegas convention center, a slightly muddy field in England, or a bar in Berlin, but those of us with a consuming interest in technology and making things have a habit of finding each other. Our events all have their own cultures which make each one slightly different from others.

The German events, for example, seem very political to my eyes — with earnest blue-haired young women seeking to make their mark as activists, while the British ones are a little more laid-back and full of middle-aged engineers seeking the bar. There are some cultural things which go beyond the superficial though and extend into the way the events are run, and it’s one of these which I think it’s time we had a chat about.

Our Community Takes Privacy Seriously

The relevant section about photography in the SHA2017 code of conduct.

The hacker community differs from the general public in many ways, one of which is that we tend to have a much greater understanding of privacy in the online age. The Average Joe will happily sign up to the latest social media craze without a care in the world, while we quickly identify it as a huge data slurp in which the end user is the product rather than the customer.

The work of privacy activists in our community in spotting privacy overreaches may pass unnoticed by outsiders, but over the years it’s scored some big wins that benefit everyone. Part of this interest in privacy appears at our events; it’s very much not done to take a photograph of someone at a hacker event without their consent. This will usually be clearly stated in the code of conduct, and thus if taking a picture featuring someone it’s imperative to make damn sure they’re OK with it.
