Celestial navigation with very little math (en)

Trammell Hudson

Learn how to find your position using a sextant and a custom slide rule, almost no math required!

Design for 3D-Printing (en)

rahix

3D-Printers have given us all the unprecedented ability to manufacture mechanical parts with a very low barrier to entry. The only thing between your idea and its physical manifestation is the process of designing the parts. However, this is actually a topic of incredible depth: Design engineering is a whole discipline to itself, built on top of tons and tons of heuristics to produce shapes that are functional, strong, and importantly: well-manufacturable In this talk, I will present the rules for designing well-printable parts and touch on other areas of design considerations so you can learn to create parts that work first try and can be reproduced by others on their 3d-printers easily.

Watch Your Kids: Inside a Children's Smartwatch (en)

Nils Rollshausen

Join us as we hack at a popular children's smartwatch and expose the secrets of every fifth child in Norway, their parents, and millions more.
Making the Magic Leap past NVIDIA's secure bootchain and breaking some Tesla Autopilots along the way (en)

Elise Amber Katze

The Tegra X2 is an SoC used in devices such as the Magic Leap One, and Tesla's Autopilot 2 & 2.5 promising a secure bootchain. But how secure really is the secure boot? In this talk I go over how I went from a secured Magic Leap One headset, to exploiting the bootloader over USB, to doing fault injection to dump the BootROM, to finding and exploiting an unpatchable vulnerability in the BootROM's USB recovery mode affecting all Tegra X2s.

BE Modded: Exploring and hacking the Vital Bracelet ecosystem (en)

cyanic

The Vital Bracelet series is an ecosystem of interactive fitness toys, content on memory chips, and apps that talk via NFC. In this talk, we'll explore the hardware and software of the series, from its obscure CPU architecture, to how it interacts with the outside world, from dumping OTP ROMs and breaking security, to making custom firmware.
When 8 Bits is Overkill: Making Blinkenlights with a 1-bit CPU (en)

girst (Tobi)

Over the last half year I have explored the Motorola mc14500 - a CPU with a true one-bit architecture - and made it simulate Conway's Game of Life. This talk gives a look into how implementing a design for such a simplistic CPU can work, and how it's possible to address 256 LEDs and half a kiloword of memory with just four bits of address space.
Learning from South Korean Telco Breaches (en)

Shinjo "peremen" Park, Yonghyu "perillamint" Ban

2025 was a bad year for South Korean mobile network operators. All three operators (SK Telecom, KT, LG U+) were affected by breach in some part of their respective network: HSS of SK Telecom, femtocells of KT. Meanwhile, handling of the breach by each operators and post-mortem analysis of each breaches have stark differences. The technical details and implemented mitigations are often buried under the vague terms, and occasionally got lost in translation to English. In this talk, I will cover the technical aspects of SK Telecom and KT's breach, and how the operators are coping to the breach and what kind of measurements have been performed to secure their network.

Von Berlin ins Exil - Lieder der 20er und 30er Jahre (de)

Kurt Tucholsky, Bertolt Brecht, Friedrich Hollaender, Claire Waldoff: Sie alle waren feste Größen des Berliner Kulturlebens. Es war wild, es war queer, es war jüdisch. Dann kamen die Nationalsozialisten an die Macht. Wer anders dachte – und sang! – wurde systematisch aus dem Land getrieben. Wer konnte, flüchtete ins ungewisse Exil.
