Building hardware - easier than ever - harder than it should be (en)

Kliment

Building electronics has never been easier, cheaper, or more accessible than the last few years. It's also becoming a precious skill in a world where commercially made electronics are the latest victim of enshittification and vibe coding. And yet, while removing technical and financial barriers to building things, we've not come as far as we should have in removing social barriers. The electronics and engineering industry and the cultures around them are hostile to newcomers and self-taught practitioners, for no good reason at all. I've been teaching advanced electronics manufacturing skills to absolute beginners for a decade now, and they've consistently succeeded at acquiring them. I'm here to tell you why it's not as hard as it seems, how to get into it, and why more people who think they can't should try.

Liberating Bluetooth on the ESP32 (en)

Antonio Vázquez Blanco (Antón)

Despite how widely used the ESP32 is, its Bluetooth stack remains closed source. Let’s dive into the low-level workings of a proprietary Bluetooth peripheral. Whether you are interested in reverse engineering, Bluetooth security, or just enjoy poking at undocumented hardware, this talk may inspire you to dig deeper.

Hacking washing machines (en)

Severin von Wnuck-Lipinski, Hajo Noerenberg

Almost everyone has a household appliance at home, whether it's a washing machine, dishwasher, or dryer. Despite their ubiquity, little is publicly documented about how these devices actually work or how their internal components communicate. This talk takes a closer look at proprietary bus systems, hidden diagnostic interfaces, and approaches to cloud-less integration of appliances from two well-known manufacturers into modern home automation systems.

Unnecessarily Complicated Kitchen – Die Wissenschaft des guten Geschmacks (de)

LukasQ

In unserer „Unnecessarily Complicated Kitchen“ hacken wir die Gesetze der Kulinarik. Ich zeige live, wie Hitze, Chemie und Chaos zusammenwirken, wenn Moleküle tanzen, Dispersionen emulgieren und Geschmack zu Wissenschaft wird. Zwischen Pfanne und Physik entdecken wir, warum Kochen im Grunde angewandtes Debugging ist – und wie man Naturgesetze so würzt, dass sie schmecken.

ISDN + POTS Telephony at Congress and Camp (en)

Harald "LaF0rge" Welte

Like 39C3, the last CCC camp (2023) and congress (38C3) have seen volunteer-driven deployments of legacy ISDN and POTS networks using a mixture of actual legacy telephon tech and custom open source software. This talk explains how this is achieved, and why this work plays an important role in preserving parts of our digital communications heritage.

FeTAp 611 unplugged: Taking a rotary dial phone to the mobile age (en)

Michael Weiner

This project transforms a classic rotary phone into a mobile device. Previous talks have analyzed various aspects of analogue phone technology, such as rotary pulse detection or ringing voltage generation. Now this project helps you get rid of the cable: it equips the classic German FeTAp 611 with battery power and a flyback SMPS based ringing voltage generator - but still maintains the classical look and feel. The talk demonstrates the journey of bridging analog and digital worlds, explaining how careful design connects a vintage phone to today’s mobile environment - in a way that will make your grandparents happy.

Pwn2Roll: Who Needs a 595€ Remote When You Have wheelchair.py? (en)

elfy

A 595€ wheelchair remote that sends a handful of Bluetooth commands. A 99.99€ app feature that does exactly what the 595€ hardware does. A speed upgrade from 6 to 8.5 km/h locked behind a 99.99€ paywall - because apparently catching the bus is a premium feature. Welcome to the wonderful world of DRM in assistive devices, where already expensive basic mobility costs extra and comes with in-app purchases! And because hackers gonna hack, this just could not be left alone.

OpenAutoLab: photographic film processing machine. Fully automatic and DIY-friendly. (en)

Kauz

OpenAutoLab, an open source machine, that is capable of processing contemporary color and black-and-white films for analogue photography, is being presented here. It made its first public appearance at 37C3 and was already seen there in action, but had no organized talk or proper presentation. Now it is better documented, waits to be built by more people and to be further developed by the community. This talk is about motivation behind developing OpenAutoLab and about the technical decisions made during it. It is argued that any dedicated film photographer is able to get one built.

From Silicon to Darude Sand-storm: breaking famous synthesizer DSPs (en)

giulioz

Have you ever wondered how the chips and algorithms that made all those electronic music hits work? Us too! At The Usual Suspects we create open source emulations of famous music hardware, synthesizers and effect units. After releasing some emulations of devices around the Motorola 563xx DSP chip, we made further steps into reverse engineering custom silicon chips to achieve what no one has done before: a real low-level emulation of the JP-8000. This famous synthesizer featured a special "SuperSaw" oscillator algorithm, which defined an entire generation of electronic and trance music. The main obstacle was emulating the 4 custom DSP chips the device used, which ran software written with a completely undocumented instruction set. In this talk I will go through the story of how we overcame that obstacle, using a mixture of automated silicon reverse engineering, probing the chip with an Arduino, statistical analysis of the opcodes and fuzzing. Finally, I will talk about how we made the emulator run in real-time using JIT, and what we found by looking at the SuperSaw code.

No-Input (de)

CooperfrauMelissengeist

Ein geschlossener Kreislauf aus Klang und Störung. Kein Instrument, kein Ursprung, nur das Rauschen, das sich selbst gebiert. Frequenzen kratzen an der Grenze zum Bewusstsein, Feedback wird zum Atem einer Maschine ohne Körper. Aus dem Dunkel des Signals erhebt sich ein sirrendes Mantra — chaotisch, unheilig, autark. Eine Beschwörung der Leere durch elektrische Selbstzerstörung.

Tippeln am Rande des Abgrunds (de)

tippel radio

Das "tipple radio" ist eine Collage von Singer-Songwriter-Konzert und szenischer Lesung. Es trägt gecoverte und selbstgeschriebene Songs und Medleys von Punk über Hamburger Schule bis Schlager mit Gitarre und Gesang vor und verknüpft die Inhalte der Songs miteinander. Es entsteht ein Geflecht von Musik und Text, dass Aufbrüche in Abgründen aufzeigt und Hoffnung macht sich gegen die Faschisierung in der Gesellschaft zusammen zu schließen.

Mittagspausenpunk live (de)

Einschiss

Einschiss ist DER Ausnahmekünstler zwischen den Stationen Paracelsus Bad und Rathaus Reinickendorf der U8. Gefangen im Körper eines Mannes mit Charaktermodell German_default_3_bearded.obj macht Einschiss Musik gegen die Dinge die nerven: Nazis, Arbeit und Consent Forms (und Arbeit). Dabei setzt er modernste Technologien ein, um einen Typen so klingen zu lassen, als wäre es ein Typ mit Backing Track. Für mehr Musiker:innen hat das Bier nicht gereicht. Sorry.

Gepflegtes Grölen am Späti: Antifa-Jodler, Punkrock und Umverteilungs-Hits (de)

elenos

Das Konzept ist simpel: Wir singen zusammen. Im Angebot haben wir vier Kategorien: Politische Classics, Punkrock-Hymnen, Antifaschistische Jodler und Umverteilungs-Hits des Quartiersmanagements Grunewald in der ansprechenden Karaoke-Variante. Man muss nichts können. Mit charmanter Anleitung manövrieren wir uns zusammen durch kollektive Dissonanzen!
