Hacking Closed-Source: Reverse Engineering Real-World Products

Closed-source software is prevalent in our everyday lives, limiting our ability to understand how it works, which privacy implication it poses to the processed data, and addressing potential issues in time. Despite the growth of open-source movements, users often have no choice but to rely on closed-source solutions, e.g., for medical devices and IoT products. We’ll discuss key techniques to help you get started with reverse engineering. Hacking your own devices can be challenging, bricking a device is not uncommon, but so is celebrating the moments of a revived and modified device.

Hacking your dishwasher for cloudless appliances

Why does your dishwasher, laundry or coffee-pot need to talk to the cloud? In this presentation, Trammell Hudson shows how he reverse engineered the encrypted connections between Home Connect appliances and the Bosch-Siemens Cloud servers, and how you can control your own appliances with your self-hosted MQTT home automation system by extracting the devices’ authentication keys and connecting to their local websocket ports. No cloud required!

Creating Hardware Development Platforms for Real-World Impact: FlowIO Platform

What does it really take do create and deploy a development platform for real-world impact? Why do we need development platforms and how can they democratize emerging fields and accelerate innovation? Why do most platform attempts fail and only very few succeed in terms of impact? I will discuss the key characteristics that any platform technology must have in order for it to be able to useful for diverse users. FlowIO was the winner of the 2021 Hackaday Grand Prize as well as over a dozen other engineering, research, and design awards.

Come join us!

You!

Whatever you’re up to.

Supercon 2022: Michael Whiteley Saves The Badge

March 3, 2023 by 6 Comments

Michael Whiteley (aka [compukidmike]) is a badgelife celebrity. Together, he and his wife Katie make up MK Factor. They have created some of the most popular electronic conference badges. Of course, even experts make mistakes and run into challenges when they dare to push the envelope of technology and delivery schedules. In his Supercon 2022 talk, There’s No Rev 2: When Badgelife Goes Wrong, Mike shares details from some of his worst badge snafus and also how he managed to gracefully pull them back from the edge of disaster.

Living the Badgelife

Attendees at the world’s largest hacker convention, DEF CON in Las Vegas, had already become accustomed to receiving and wearing very cool and novel admission tokens, more properly known as badges. Then in 2006, at DEF CON 14, everything changed. Designed by Joe Grand, the first electronic DEF CON badge was a circuit board featuring a tiny PIC microcontroller, two LEDs, and a single pushbutton. Badgelife was born.

DEF CON 30 Humans Sampling Board

Mike begins his war stories with one about the DEF CON 30 badge. This was a herculean project with 25,000 badges being produced on a short timeline in the ever-changing chaos of a semiconductor supply-chain meltdown. Even though many regard it as one of the best DEF CON badges ever made, the DC30 badge posed a number of challenges to its creators. Microcontrollers were in short supply during 2021 and 2022 forcing the badge team to keep an eye on component vendor supplies in order to snipe chips as soon as they appeared in stock. The DC30 badge was actually redesigned repeatedly as different microcontrollers fluctuated in and out of supply. Continue reading “Supercon 2022: Michael Whiteley Saves The Badge” →

Hacker Hotel 2023: Back Again!

March 2, 2023 by 13 Comments

After three years, it’s odd to think back to those few weeks before the COVID-19 pandemic morphed from something on the news into an immediate and ever-present threat which kept us isolating for so long. For me, some of the last moments of normality were a trip to the Netherlands for Hacker Hotel, a hacker event in the comfort of a resort hotel. Now three years later and after two cancelled events, Hacker Hotel is back, and I made the same journey to Garderen to hang out for a weekend with a bunch of hacker friends over some good Dutch beer and a lot of bitterballen.

FOSDEM 2023: An Open-Source Conference, Literally

March 1, 2023 by 6 Comments

Every year, on the first weekend of February, a certain Brussels university campus livens up. There, you will find enthusiasts of open-source software and hardware alike, arriving from different corners of the world to meet up, talk, and listen. The reason they all meet there is the conference called FOSDEM, a long-standing open-source software conference which has been happening in Belgium since 2000. I’d like to tell you about FOSDEM because, when it comes to conferences, FOSDEM is one of a kind.

FOSDEM is organized in alignment with open-source principles, which is to say, it reminds me of an open-source project itself. The conference is volunteer-driven, with a core of staff responsible for crucial tasks – yet, everyone can and is encouraged to contribute. Just like a large open-source effort, it’s supported by university and company contributions, but there’s no admission fees for participants – for a conference, this means you don’t have to buy a ticket to attend. Last but definitely not least, what makes FOSDEM shine is the community that it creates.

FOSDEM’s focus is open software – yet, for hackers of the hardware world, you will find a strong hardware component to participate in, since a great number of FOSDEM visitors are either interested in hardware, or even develop hardware-related things day-to-day. It’s not just that our hardware can’t live without software, and vice-versa – here, you will meet plenty of pure software, a decent amount of pure hardware, and a lot of places where the two worlds are hard to distinguish. All in all, FOSDEM is no doubt part of hacker culture in Europe, and today, I will tell you about my experience of FOSDEM 2023. Continue reading “FOSDEM 2023: An Open-Source Conference, Literally” →

Supercon 2022: Selling Your Company And Not Your Soul

February 28, 2023 by 11 Comments

Haddington Dynamics is a particular company. After winning the 2018 Hackaday Prize with an open-source robotic arm, we’ve covered their micro-factories and suction cup end-effectors for making face shields during 2020. They’ve been laser-focused on their mission of creating a fantastic robot arm at a small price tag with open-source software and design. So how does a company with such a hacker ethos get bought by a much larger company, and why? They came to SuperCon 2022 to share their story in a panel discussion.

Haddington Dynamics started with two clever inventions: optical encoders that used analog values instead of digital values and an FPGA that allowed them to poll those encoders and respond rapidly. This allowed them to use cheaper motors and rely on the incredibly sensitive encoders to position them. After the Hackaday prize, they open-sourced the HD version of the robot and released the HDI version. But in 2020, they were bought by a group called Ocado. As to why the somewhat practical but not exciting answer is that they needed money. Employees needed to be paid, and they needed capital to keep the doors open.

So this leads to the next tricky question, how do you sell your company without changing it? The fine folks at Haddington Dynamics point out in their panel discussion that a company is a collection of people. The soul of that company is the collective soul of those people coming together. A company being bought can be akin to stopping working for yourself and going to work for someone else. Working alone, you have values and principles that you can easily stick to. But once you start working for someone else, they will value different things, and while the people that make up the company might not change, the company’s decisions might become unrecognizable.

As the panel points out, looking for a buyer with the same values is critical. Ocado was a great fit as their economic interests and culture matched Haddington’s. However, it’s not all roses, as Ocadao tends to be a very closed-source group. However, Haddington Dynamics still supports its open-source initiatives. It’s a fascinating look into a company’s life cycle and how they navigate the waters of open-source, funding, acquisitions, innovation, and invention. Despite the fairytale-like nature of inventing a revolutionary robot arm in your garage and winning many awards, it turns out there is quite a lot that happens after the happily ever after.

We look forward to seeing more of Haddington Dynamics and where they go next. Video after the break.

Supercon 2022: Tap Your Rich Uncle To Fund Your Amateur Radio Dreams

February 23, 2023 by 11 Comments

Imagine you had a rich uncle who wanted to fund some of your projects. Like, seriously rich — thanks to shrewd investments, he’s sitting on a pile of cash and is now legally obligated to give away $5,000,000 a year to deserving recipients. That would be pretty cool indeed, but like anything else, if it sounds too good to be true, it probably is, right?

Well, maybe not. It turns out that we in the amateur radio community — and even amateur radio adjacent fields — have a rich uncle named Amateur Radio Digital Communications (ARDC), a foundation with a large endowment and a broad mission to “support amateur radio, funds scholarships and worthy educational programs, and financially support technically innovative amateur radio and digital communications projects.” As the foundation’s Outreach Manager John Hayes (K7EV) explained at Supercon 2022, ARDC is a California-based 501(c)3 non-profit organization that has been in the business of giving away money to worthy projects in the amateur radio space since 2021.

Travel The World Looking For Retro Tech, Virtually

February 21, 2023 by 1 Comment

For those who have a passion for vintage hardware, whether it be a classic computer or a war-surplus ham radio rig, finding the things without resorting to paying shipping fees on eBay can sometimes be tricky. Your best bet is to find a local fair or swap event, but it always seems they’re the kind of thing you find out about the weekend after they were held.

Looking to make these sort of events more visible and easier to keep track of, [RobSmithDev] has created the Retro.Directory. Scrolling your way across the globe you can see markers that indicate places of interest for the retro aficionado, such as museums, repair shops, and old school arcades, as well as upcoming events.
