Maybe you don't trust a cloud-hosted service with your highly classified information, or perhaps you like to build things for yourself. In this light-hearted talk, you will learn how to make a real-time on-device GenAI-powered application that can live transcribe and summarize conversations without internet access, using open-source components.\n\nOur journey begins with an introduction to open-source LLMs and the latest trends in running GenAI tools on your own hardware. We will build up our application step-by-step, first creating a live streaming voice-to-text transcription pipeline, then an LLM-based conversation summarization layer, presented within a Streamlit frontend, with conversation summaries sent to a lightweight Django API backend for storage.\n\nHere's why this matters:\n1️⃣ Cloud-hosted SaaS tools cannot store highly sensitive information.\n2️⃣ Good open-source alternatives exist for most GenAI tasks; the more people who use them, the more they will thrive.\n3️⃣ Commercial tools will solve for common use cases, but developers can build personalised tools that are highly specialised for their own bespoke needs.\n\nThis talk is tailored for Python enthusiasts and requires no ML expertise. By seeing a practical demo come together piece by piece, attendees will gain a deeper understanding of how to build their own complex Generative AI applications and be pushed to imagine what they could make for themselves using on-device computation in real-world scenarios. Expect plenty of Python code and some fun live demos, with GitHub code provided for attendees to try it at home.\n\nLicensed to the public under https://creativecommons.org/licenses/by-sa/4.0/","original_language":"eng","persons":["John Sandall"],"tags":["183","emf2024","talk","Stage C","2024","Day 2"],"view_count":173,"promoted":false,"date":"2024-05-31T13:50:00.000+02:00","release_date":"2024-12-02T00:00:00.000+01:00","updated_at":"2026-01-13T13:15:22.900+01:00","length":1627,"duration":1627,"thumb_url":"https://static.media.ccc.de/media/events/emf/2024/183-ff217439-581e-5530-80eb-976fea6e1cf9.jpg","poster_url":"https://static.media.ccc.de/media/events/emf/2024/183-ff217439-581e-5530-80eb-976fea6e1cf9_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/emf/2024/183-ff217439-581e-5530-80eb-976fea6e1cf9.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/emf/2024/183-ff217439-581e-5530-80eb-976fea6e1cf9.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/emf2024-183-whispered-secrets","url":"https://api.media.ccc.de/public/events/ff217439-581e-5530-80eb-976fea6e1cf9","conference_title":"Electromagnetic Field 2024","conference_url":"https://api.media.ccc.de/public/conferences/emf2024","related":[]},{"guid":"9f27b602-c117-5628-82d4-dc649a649638","title":"Opening Ceremony","subtitle":null,"slug":"emf2024-550-opening-ceremony","link":"https://www.emfcamp.org/schedule/2024/550-opening-ceremony","description":"The ceremony in which we open the festival.

If the stars align, you'll be able to see everything working on a real demonstration panel, too!\n\nAlthough we'll be going into detail on some bits, this talk should be accessible to most audiences.","original_language":"eng","persons":["eta"],"tags":["199","emf2024","talk","Stage A","2024","Day 4"],"view_count":724,"promoted":false,"date":"2024-06-02T18:10:00.000+02:00","release_date":"2024-08-31T00:00:00.000+02:00","updated_at":"2026-04-02T23:15:05.059+02:00","length":1834,"duration":1834,"thumb_url":"https://static.media.ccc.de/media/events/emf/2024/199-5f069572-a15b-5da2-ae3e-d047d288983d.jpg","poster_url":"https://static.media.ccc.de/media/events/emf/2024/199-5f069572-a15b-5da2-ae3e-d047d288983d_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/emf/2024/199-5f069572-a15b-5da2-ae3e-d047d288983d.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/emf/2024/199-5f069572-a15b-5da2-ae3e-d047d288983d.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/emf2024-199-driving-fancy-led-panels-with-commodity-hardware","url":"https://api.media.ccc.de/public/events/5f069572-a15b-5da2-ae3e-d047d288983d","conference_title":"Electromagnetic Field 2024","conference_url":"https://api.media.ccc.de/public/conferences/emf2024","related":[]},{"guid":"8aaf419c-a552-5a6b-bf50-c8d0a82836be","title":"Live tour of the Boulby Underground Laboratory - a special science facility 1.1km underground!","subtitle":null,"slug":"emf2024-282-live-tour-of-the-boulby-underground-laboratory","link":"https://www.emfcamp.org/schedule/2024/282-live-tour-of-the-boulby-underground-laboratory","description":"A rare live two way link with the Boulby Underground Laboratory, where the Boulby team will give us a tour of the underground facilities that include a Mars Yard, where real (and LEGO) Mars rovers are tested, multiple Dark Matter research experiments, understanding the radioactivity of substances and more!\n\nHave any questions you want answered?

Conventional hardware architectures and the C/C++ codebase are chronically prone to exploitable errors - a 75-year-old problem at the heart of computing.  \n\nThis talk will introduce CHERI, showing how (finally?!) we can do better.  The CHERI research project has developed a new architecture+software approach, using unforgeable hardware capabilities to implement pointers. Morello is an Arm experimental platform for evaluation of CHERI to explore its potential for mass-market adoption, part-funded by the UKRI Digital Security by Design programme, and other groups are developing CHERI-enabled RISC-V processors, including Microsoft, Google, lowRISC, SCI Semiconductor, Codasip, and RISC-V International. \n\nThis talk will introduce the problem, and CHERI and Morello, for a broad audience: the hardware extensions, their potential for fine-grained memory safety and software compartmentalisation, the CHERI software stack, and machine-checked mathematical proof that the architecture design provides the intended security. CHERI complements alternative high-level-language approaches, that would need code to be rewritten from scratch, and we'll talk about the often-low cost of porting code to CHERI. \n\nI'll demo how CHERI prevents exploitable memory safety errors on a Morello box,  running Arm CHERI hardware and a complete CHERI software stack.\n\nThis is joint work by the CHERI and Morello teams at the University of Cambridge, Arm, SRI International, and the University of Edinburgh.","original_language":"eng","persons":["Peter Sewell"],"tags":["87","emf2024","talk","Stage C","2024","Day 2"],"view_count":138,"promoted":false,"date":"2024-05-31T18:30:00.000+02:00","release_date":"2024-08-31T00:00:00.000+02:00","updated_at":"2026-03-31T17:45:06.999+02:00","length":1834,"duration":1834,"thumb_url":"https://static.media.ccc.de/media/events/emf/2024/87-b3ecfa2a-5f57-53ff-8442-ab1aea12c561.jpg","poster_url":"https://static.media.ccc.de/media/events/emf/2024/87-b3ecfa2a-5f57-53ff-8442-ab1aea12c561_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/emf/2024/87-b3ecfa2a-5f57-53ff-8442-ab1aea12c561.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/emf/2024/87-b3ecfa2a-5f57-53ff-8442-ab1aea12c561.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/emf2024-87-cheri-and-arm-morello","url":"https://api.media.ccc.de/public/events/b3ecfa2a-5f57-53ff-8442-ab1aea12c561","conference_title":"Electromagnetic Field 2024","conference_url":"https://api.media.ccc.de/public/conferences/emf2024","related":[]},{"guid":"3957c32a-07d7-5d17-b419-53e41fb53676","title":"Mothers' G(q)uilt: An exploration of mothers' experiences through an interactive quilt","subtitle":null,"slug":"emf2024-34-mothers-g-q-uilt","link":"https://www.emfcamp.org/schedule/2024/34-mothers-g-q-uilt","description":"This is a talk about how we combined textiles, electronics and storytelling to provide a platform for people to share experiences. \nFor this project, we wanted to explore more the findings of previous research around the guilt mothers feel when feeding their babies, but in a more creative way. Coming at the project from 3 very different points of expertise, we worked with mums to design and make a touch interactive quilt.\nWe asked mothers of young babies to describe their emotions around feeding, a topic often emotional and controversial, and send a voice clip along with a piece of their baby’s clothing which we stitched together to create a special interactive quilt. The quilt is embedded with electronic touch sensors which activate the clips when the metal buttons of the clothes are touched. By interacting with them you can hear the stories through headphones. All this results in a very intimate and emotional experience that provides a platform for visibility and understanding and we think is a great conversation starter to share stories and create community. \nThe talk will include a timeline of how we created a digitally augmented quilt, and a few thoughts if you want to make one too.

Beyond this, it's surprisingly rare to find good information beyond the basic physics and the marketing promise of unlimited, clean energy.\n\nAs an engineer working in the fusion technology sector, I give a primer on how fusion power works, why its benefits are so incredibly tantalising yet hard to achieve, what the latest exciting developments are, and how the UK is a surprising trailblazer. I outline some of the cutting-edge technologies involved in developing fusion power, including superconducting magnets, plasma control using deep learning methods, and hypersonic fuel injection. The audience is also given facts and figures to get a flavour of the unimaginable scale of what is being done: materials at nearly 0K adjacent to plasmas hotter than the cores of stars, gigawatts of power from teaspoons of fuel, magnetic fields multiple times more powerful than MRI machines, and neutron fluxes strong enough to transmute matter in bulk.\n\nComing away from this presentation, the audience will have learned about the fundamentals of nuclear fusion and appreciate the key issues enough to put the marketing and news reports into context. They might even be excited and enthused about what's to come in this quickly growing technology space.","original_language":"eng","persons":["James Pope"],"tags":["471","emf2024","talk","Stage C","2024","Day 4"],"view_count":127,"promoted":false,"date":"2024-06-02T17:10:00.000+02:00","release_date":"2024-08-31T00:00:00.000+02:00","updated_at":"2026-03-23T14:15:07.494+01:00","length":1817,"duration":1817,"thumb_url":"https://static.media.ccc.de/media/events/emf/2024/471-0c31ac3d-9261-579d-bfb5-78961a8c2539.jpg","poster_url":"https://static.media.ccc.de/media/events/emf/2024/471-0c31ac3d-9261-579d-bfb5-78961a8c2539_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/emf/2024/471-0c31ac3d-9261-579d-bfb5-78961a8c2539.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/emf/2024/471-0c31ac3d-9261-579d-bfb5-78961a8c2539.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/emf2024-471-unlimited-power","url":"https://api.media.ccc.de/public/events/0c31ac3d-9261-579d-bfb5-78961a8c2539","conference_title":"Electromagnetic Field 2024","conference_url":"https://api.media.ccc.de/public/conferences/emf2024","related":[]},{"guid":"d3df2a08-5f78-5b6f-8c05-a717da510047","title":"Gas boilers suck!

In rural areas, we often lose cellular wireless signal entirely, even within highly technologically advanced economies such as the UK, EU, US etc. We then find that we are unable to send or receive text messages, even emergency messages. \n\nIn the 1990s, visionary scientists and engineers developed alternative voice and messaging systems, using satellites as their ‘flying’ cell towers. We will discuss an example of such a pioneering network, called Iridium, which has operated successfully from the late 1990s right up to the present day. Today’s scientist and engineer visionaries are now proposing that the same ‘space-based’ capabilities could be added to our everyday smartphones, without needing to purchase a separate satellite-messaging device. This would allow our phone, when necessary, to switch from the land-based TN to the space-based ‘Non-Terrestrial Network’ (NTN). In this presentation we will discuss some of the technical challenges in achieving this ‘Direct-to-Device’ (D2D) satellite messaging feature, and some of the solutions which are being proposed, and even already being tested for real. One of the leading players in this space is Starlink, so buckle up for a wild ride!\n\nLicensed to the public under https://creativecommons.org/licenses/by-sa/4.0/","original_language":"eng","persons":["Damian Bevan"],"tags":["40","emf2024","talk","Stage B","2024","Day 2"],"view_count":71,"promoted":false,"date":"2024-05-31T12:00:00.000+02:00","release_date":"2024-11-19T00:00:00.000+01:00","updated_at":"2026-03-15T23:30:04.777+01:00","length":1499,"duration":1499,"thumb_url":"https://static.media.ccc.de/media/events/emf/2024/40-5663e52f-d7a2-5911-9dac-7e08b2773517.jpg","poster_url":"https://static.media.ccc.de/media/events/emf/2024/40-5663e52f-d7a2-5911-9dac-7e08b2773517_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/emf/2024/40-5663e52f-d7a2-5911-9dac-7e08b2773517.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/emf/2024/40-5663e52f-d7a2-5911-9dac-7e08b2773517.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/emf2024-40-sending-text-messages-through-space","url":"https://api.media.ccc.de/public/events/5663e52f-d7a2-5911-9dac-7e08b2773517","conference_title":"Electromagnetic Field 2024","conference_url":"https://api.media.ccc.de/public/conferences/emf2024","related":[]},{"guid":"7cf86acc-8054-55e9-ac09-ef0c0e07c675","title":"Explosion in a Tunnel; Understanding Swiss Cheese","subtitle":null,"slug":"emf2024-97-explosion-in-a-tunnel-understanding-swiss-cheese","link":"https://www.emfcamp.org/schedule/2024/97-explosion-in-a-tunnel-understanding-swiss-cheese","description":"The talk takes a deep-dive into the Abbeystead explosion (using pretty much all available sources available on the subject), one of the worst civil engineering disasters in post-war history, through the lens of the HSE investigation.

And if you didn't, this talk will explain why you should care about a now 40-year-old game.\n\nIt was years ahead of its time, with 3D graphics, a procedurally generated open world, and a whole novel's worth of lore - all running on an 8-bit home microcomputer in 1984, when most games were little more advanced than Pac-Man or Space Invaders.\n\nOver the last few years, I've been picking apart the original Elite game engine to understand how it worked, and also to experiment with extending it.\n\nIn this talk, I'll examine some of the methods that the game used - how it used the graphics hardware, how the game state is represented in memory, how the ship models were designed, how the AI worked, and how galaxies and planets were generated. I'll also explain some quirks of the game... including the real reason that docking was so hard.\n\nI'll demonstrate some new tools I've developed, which access the game state in real time, letting you experience the original game in new ways - including an OpenGL frontend with VR support, and an attempt to recreate an arcade-style version of the game, with an old-school vector display.\n\nFinally, if all goes to plan, I will attempt to demonstrate something that was an impossible dream for 40 years: multiplayer Elite on the original BBC Micro version.","original_language":"eng","persons":["Martin Ling"],"tags":["113","emf2024","talk","Stage B","2024","Day 3"],"view_count":156,"promoted":false,"date":"2024-06-01T13:40:00.000+02:00","release_date":"2024-08-31T00:00:00.000+02:00","updated_at":"2026-03-12T19:45:04.637+01:00","length":2124,"duration":2124,"thumb_url":"https://static.media.ccc.de/media/events/emf/2024/113-fec079b8-9645-501f-bb93-2757dc89bbc0.jpg","poster_url":"https://static.media.ccc.de/media/events/emf/2024/113-fec079b8-9645-501f-bb93-2757dc89bbc0_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/emf/2024/113-fec079b8-9645-501f-bb93-2757dc89bbc0.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/emf/2024/113-fec079b8-9645-501f-bb93-2757dc89bbc0.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/emf2024-113-exploring-and-extending-the-elite-game-engine","url":"https://api.media.ccc.de/public/events/fec079b8-9645-501f-bb93-2757dc89bbc0","conference_title":"Electromagnetic Field 2024","conference_url":"https://api.media.ccc.de/public/conferences/emf2024","related":[]},{"guid":"43224c6c-2853-5a95-a94c-42eac0ef37f7","title":"Is everything difficult, or is it just me?","subtitle":null,"slug":"emf2024-321-is-everything-difficult-or-is-it-just-me","link":"https://www.emfcamp.org/schedule/2024/321-is-everything-difficult-or-is-it-just-me","description":"It isn't just you.\n\nThere are so many pressures on us, not only from our jobs and industry, but from the state of society, politics and the economy as a whole.\n\nJoin me on a joyful journey through the alphabet of overwhelm, we’ll cover Anxiety, Burnout, Capitalism, Depression, Emotional Labour and many other fun factors.

The targeted advertising and influence platforms give public sector actors complex tools with which to target behaviour change communications - allowing them to tailor nudge messages based on online behaviour, interests, and fine-detail location. This is allowing the police to use targeted behaviour change advertising to attempt to prevent crime before it happens - but poses serious questions for accountability, ethics, and privacy.\n\nDrawing on a dataset of more than 12,000 government adverts from the Meta Ad Library and in-depth interviews with law enforcement, we map the landscape of what we call 'influence policing' in the UK, and discuss the ethical and democratic implications of this new mode of policing.","original_language":"eng","persons":["Ben Collier"],"tags":["237","emf2024","talk","Stage B","2024","Day 3"],"view_count":60,"promoted":false,"date":"2024-06-01T14:30:00.000+02:00","release_date":"2024-08-31T00:00:00.000+02:00","updated_at":"2026-03-30T19:15:06.668+02:00","length":1783,"duration":1783,"thumb_url":"https://static.media.ccc.de/media/events/emf/2024/237-2cb90397-ae27-5e21-a042-ed9324f6aa30.jpg","poster_url":"https://static.media.ccc.de/media/events/emf/2024/237-2cb90397-ae27-5e21-a042-ed9324f6aa30_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/emf/2024/237-2cb90397-ae27-5e21-a042-ed9324f6aa30.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/emf/2024/237-2cb90397-ae27-5e21-a042-ed9324f6aa30.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/emf2024-237-influence-policing","url":"https://api.media.ccc.de/public/events/2cb90397-ae27-5e21-a042-ed9324f6aa30","conference_title":"Electromagnetic Field 2024","conference_url":"https://api.media.ccc.de/public/conferences/emf2024","related":[]},{"guid":"8066bf25-67d9-57e4-b945-d6f23ba1ada6","title":"From Haunted Karaoke to the Humour Feature: an Exploration of Auto-Generated Comedy","subtitle":null,"slug":"emf2024-169-from-haunted-karaoke-to-the-humour-feature","link":"https://www.emfcamp.org/schedule/2024/169-from-haunted-karaoke-to-the-humour-feature","description":"In a world where large language models like GPT and Gemini are becoming more and more ubiquitous, what does this mean for comedy?

Every day I deal with the records that people chose to save, or forgot to destroy. Archival material ranges from the sublime (Royal wills, lost love letters, newspapers announcing the Titanic’s demise) to the ridiculous (broken chips of wax from old seals, IOUs from unknown persons, too much human hair).\n\nA key role of an archivist is to decide what to save and what to destroy. But this is the past. Today most records are no longer on paper but sent in the form of bytes and I’ve started to wonder what the point of my job really is? We have free access to near-unlimited email inboxes, all our photos are backed up to the cloud to access from anywhere, and instant messaging is synced between our devices. Why bother deciding what to keep for posterity? Just save everything, let computers do the hard work, and all will be well. \n\nThis approach unsettled me so much that I set off to explore what it would really mean if we “saved everything”: how this would affect our world, communities, and ourselves as humans. In this talk, I will share this journey and my thoughts with you, and try to persuade you that my job is not in fact pointless.","original_language":"eng","persons":["Erinna Cave"],"tags":["253","emf2024","talk","Stage B","2024","Day 3"],"view_count":44,"promoted":false,"date":"2024-06-01T12:20:00.000+02:00","release_date":"2024-08-31T00:00:00.000+02:00","updated_at":"2025-05-02T15:45:06.816+02:00","length":1438,"duration":1438,"thumb_url":"https://static.media.ccc.de/media/events/emf/2024/253-d24923d5-a096-5a26-a639-853139206b9c.jpg","poster_url":"https://static.media.ccc.de/media/events/emf/2024/253-d24923d5-a096-5a26-a639-853139206b9c_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/emf/2024/253-d24923d5-a096-5a26-a639-853139206b9c.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/emf/2024/253-d24923d5-a096-5a26-a639-853139206b9c.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/emf2024-253-are-archivists-pointless-when-the-cloud-can-just-save","url":"https://api.media.ccc.de/public/events/d24923d5-a096-5a26-a639-853139206b9c","conference_title":"Electromagnetic Field 2024","conference_url":"https://api.media.ccc.de/public/conferences/emf2024","related":[]},{"guid":"4ba3664b-209b-58b7-b30d-8645f837b057","title":"The XZ backdoor - what, why, and how?","subtitle":null,"slug":"emf2024-409-the-xz-backdoor-what-why-and-how","link":"https://www.emfcamp.org/schedule/2024/409-the-xz-backdoor-what-why-and-how","description":"Earlier this year, a developer was trying to benchmark a database. But something was wrong - SSH was taking up too much CPU time in the background. This accidental observation led to the discovery of an audacious attempt to introduce a backdoor that would allow an attacker access to almost any system in the world running SSH, an attack made up of both technical and social components.\n\nThis talk will describe the backdoor itself, the process that went into it being possible to inject in the first place, and how this was exacerbated by a series of entirely reasonable decisions on the part of Linux distributions. It's a story of social engineering, novel obfuscation mechanisms, and a long con over several years. We'll delve into why distributions patch upstream code, why dependency chains are complicated, and how it's even possible for a compression library to break all the SSH security mechanisms that are intended to prevent this sort of thing from happening in the first place.","original_language":"eng","persons":["Matthew Garrett"],"tags":["409","emf2024","talk","Stage A","2024","Day 2"],"view_count":400,"promoted":false,"date":"2024-05-31T17:40:00.000+02:00","release_date":"2024-08-31T00:00:00.000+02:00","updated_at":"2026-03-20T13:00:07.164+01:00","length":1826,"duration":1826,"thumb_url":"https://static.media.ccc.de/media/events/emf/2024/409-4ba3664b-209b-58b7-b30d-8645f837b057.jpg","poster_url":"https://static.media.ccc.de/media/events/emf/2024/409-4ba3664b-209b-58b7-b30d-8645f837b057_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/emf/2024/409-4ba3664b-209b-58b7-b30d-8645f837b057.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/emf/2024/409-4ba3664b-209b-58b7-b30d-8645f837b057.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/emf2024-409-the-xz-backdoor-what-why-and-how","url":"https://api.media.ccc.de/public/events/4ba3664b-209b-58b7-b30d-8645f837b057","conference_title":"Electromagnetic Field 2024","conference_url":"https://api.media.ccc.de/public/conferences/emf2024","related":[]},{"guid":"edfe7262-4612-56da-b6f9-42a34c3577f0","title":"From Tax Law to Tangible Dreams: An Accidental Maker's Journey","subtitle":null,"slug":"emf2024-186-from-tax-law-to-tangible-dreams-an-accidental-makers-journey","link":"https://www.emfcamp.org/schedule/2024/186-from-tax-law-to-tangible-dreams-an-accidental-makers-journey","description":"I was trained as a tax lawyer and data scientist as a profession but I always wanted to build.

This unique book blends storytelling with 3D paper origami, touch sensors, cloud-based audio features, making ancient wisdom fun and engaging for young minds.

Then once the data is collected underground, how open source software has been developed by cavers to process the data and draw maps which adjust to later changes in positions of parts of the cave when more data is collected or corrected.

We’ve looked at whether Artificial Intelligence, combined with sonar, can automatically spot and classify interesting underwater objects. We’ve tried several approaches, some more successful than others, but there are promising results with movement detection and segmentation. \n\nThis talk covers our initial findings - where we went wrong and one promising approach that we are still actively researching.

Inspired by David Graeber's idea of the sustainable activities of play and care, EveryWhere aims to make new rituals around technology that allow the network to exist across generations. In 2022 we convened a group of artists, technologists, designers and activists to start the project. As result of the connections made, we have identified themes and ideas that we will present in this talk. The five themes are Community, Sustainability, Software, Hardware and Creative.

A modern performing arts space is no longer several independent systems providing show elements such as light and sound, but rather an IP network fabric delivering the desired elements flexibly around the venue and sometimes beyond. As a community we have gathered a good understanding of designing reasonably secure networks and protocols I would like to apply this knowledge to the unique demands of a theatre.\n\nIf you often find yourself distracted by the coordination of the light fixtures rather than the performance this talk is for you. Or may you just like designing networks and learning about interesting protocols.\n\nI previously covered Audio over IP in a talk at MCH2022: https://media.ccc.de/v/mch2022-113-audio-networks-and-their-security-implications\n\nIn the interest of transparency I am partially employed (and was previously fully employed) by Holoplot a professional audio company that principally sells network based loud speakers. I'm also a freelance security consultant.

Artists and their shows constantly seek the latest lighting \u0026 video technology, intricate stage setups, and top-notch audio quality to dazzle fans. Ticket sales are a major revenue stream for Artists, and a high-quality production show, sells tickets.\n\nThis high level of production is only possible because of an industry full of talented roadies. Behind every arena or stadium show lies a hundreads of engineers tirelessly setting up, operating, and dismantling these elaborate stage setups, often in a new venue, on a daily basis. Long gone are the days of makeshift equipment cobbled together, roadies now navigate highly sophisticated AV control systems supported by intricate network infrastructures.\n\nA vast array of specialised hardware caters specifically to live events, engineered to be both flexible for on-the-fly adjustments and durable for daily setup and teardown. Reliability is paramount, with equipment expected to perform flawlessly show after show, never missing a beat. \n\nIn this talk we are going to take an overview into the world of live event production, shedding light on how roadies consistently deliver stellar performances day in and day out. We'll explore the intricacies of AV networks, offering an insightful overview of the behind-the-scenes magic that brings unforgettable concerts to life.\n\nLicensed to the public under https://creativecommons.org/licenses/by-sa/4.0/","original_language":"eng","persons":["Nicholas Whitehead"],"tags":["450","emf2024","talk","Stage B","2024","Day 2"],"view_count":153,"promoted":false,"date":"2024-05-31T15:50:00.000+02:00","release_date":"2024-12-01T00:00:00.000+01:00","updated_at":"2026-03-06T20:30:06.058+01:00","length":1732,"duration":1732,"thumb_url":"https://static.media.ccc.de/media/events/emf/2024/450-103759a0-37c3-58c0-84e2-0fa76bd0f297.jpg","poster_url":"https://static.media.ccc.de/media/events/emf/2024/450-103759a0-37c3-58c0-84e2-0fa76bd0f297_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/emf/2024/450-103759a0-37c3-58c0-84e2-0fa76bd0f297.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/emf/2024/450-103759a0-37c3-58c0-84e2-0fa76bd0f297.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/emf2024-450-how-roadies-became-network-engineers","url":"https://api.media.ccc.de/public/events/103759a0-37c3-58c0-84e2-0fa76bd0f297","conference_title":"Electromagnetic Field 2024","conference_url":"https://api.media.ccc.de/public/conferences/emf2024","related":[]},{"guid":"6008fd8f-5243-516c-b8b8-f5cf32cb8d62","title":"Astrophysics for Supervillains","subtitle":null,"slug":"emf2024-428-astrophysics-for-supervillains","link":"https://www.emfcamp.org/schedule/2024/428-astrophysics-for-supervillains","description":"“Could you crash the Moon into the Earth?”\n“If the Sun explodes, would we all get vaporized?”\n“What’s the weather like on Mercury?”\n\nDiscover the answers to these questions (and many more!) at \"Astrophysics for Supervillains\"!

You need a high-resolution computer display for fine drawings (e.g. CAD diagrams). Memory's EXPENSIVE, processors are slow: what to do? Here's an analog solution to a digital problem: an unusual cathode-ray tube that preserves whatever it draws with no flickering, fading, or any kind of refresh. A brilliant dot sears emerald trails into the screen, rendering intricate line-art without pixels. No need for video memory when the screen itself remembers!\n\nIt's mesmerising to see this special tube in action; more satisfying still to know how it works. Discover a mechanism Tektronix refined over three decades, growing from palm-sized oscilloscope readouts to 25\" computer-lab behemoths. A wreath of electron guns, kilovolt potentials, microscopic cobalt cones, and transparent anodes set the stage for a nonlinear dance of charges that yields visualisations with style --- and we'll unravel its mysteries with animated diagrams. En route we'll visit notable storage tube applications, from early computer memories to 1978's _Battlestar Galactica_. Of course we'll see a real Tektronix terminal at work, too!\n\nComputer memory is cheap now: by the mid 1980s, modern displays had advantages storage-tube systems couldn't overcome. Nobody's making them anymore, so check out this talk while old stock still works!\n\nLicensed to the public under https://creativecommons.org/licenses/by-sa/4.0/","original_language":"eng","persons":["Tom Stepleton"],"tags":["43","emf2024","talk","Stage B","2024","Day 3"],"view_count":132,"promoted":false,"date":"2024-06-01T16:30:00.000+02:00","release_date":"2024-12-01T00:00:00.000+01:00","updated_at":"2026-03-25T00:15:03.833+01:00","length":1568,"duration":1568,"thumb_url":"https://static.media.ccc.de/media/events/emf/2024/43-7649c47c-30ca-54ad-a308-08a3a7663853.jpg","poster_url":"https://static.media.ccc.de/media/events/emf/2024/43-7649c47c-30ca-54ad-a308-08a3a7663853_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/emf/2024/43-7649c47c-30ca-54ad-a308-08a3a7663853.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/emf/2024/43-7649c47c-30ca-54ad-a308-08a3a7663853.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/emf2024-43-forgotten-graphics-technology","url":"https://api.media.ccc.de/public/events/7649c47c-30ca-54ad-a308-08a3a7663853","conference_title":"Electromagnetic Field 2024","conference_url":"https://api.media.ccc.de/public/conferences/emf2024","related":[]},{"guid":"ee455553-80d5-5fed-aba6-3422e2795516","title":"Making Music with Hair","subtitle":null,"slug":"emf2024-202-making-music-with-hair","link":"https://www.emfcamp.org/schedule/2024/202-making-music-with-hair","description":"Combining his deep interest in the biology of hair with generative music systems, Chris will give you a an insight into how he has brought the two fields together. \n\nAfter a chance introduction to an Austrailian biology student in 2022, Chris and Jay have spent the last few years researching the mechanics of hair growth, the structures of Amino Acids and Keratins and the composition of different parts of human hair.

It explores the fragility of life, its circularity, invites people to celebrate the moment we are in right now and questions our legacy as humans moving into an increasingly digital age. \n\nSince January 2024, Peasgood \u0026 Hanslip have worked with DDSP-SVC, a newly-developed process which builds on Google Magenta’s DDSP by combining it with a diffusion-based vocoder. They recorded vocal datasets with people aged 5-95 and trained models which can be mapped onto Emily’s voice enabling her to sound younger and older than she is. \n\nThis technology is starting to be adopted by contemporary pop musicians, high-profile examples being web services such as Grimes’ Elf and Holly Herndon’s Holly+. \n\nEverSong represents a new application of this technology by making it possible to hear a voice age in real time.

Speak it, of course!\n\nLike many programmers and heavy computer users, I suffer from chronic hand pain aggravated by computer keyboard use (often called repetitive strain injury, or RSI). After having mild symptoms for years, in 2019 my hand pain worsened from irritating to unignorable. Eventually I got desperate enough to try to learn to code by voice. To my surprise, it worked.\n\nSpeech recognition technology has advanced dramatically in the past decade, but most people’s ideas about voice-driven UI are based on highly limited voice assistants like Siri or Alexa, powerful but imprecise tools like LLMs, or special-purpose dictation tools. What does a voice interface for precise control by expert users look like?\n\nA small but growing community of programmers, many affected by RSI, have been developing tools that explore this question. I use one such tool, called Talon, to control my computer, write and edit computer code, and even to write my dissertation. In this talk, I will live-demo how I edit code by voice, as well as tackling the following questions:\n\n1. What is voice-coding like? What unique challenges does it present?\n2. How do voice control systems like Talon work under the hood?\n3. Could voice coding ever be *better* than typing?\n4.

Armed with a PA system, rally lights, under glow and 2 car horns it’s the perfect centre of chaos for protests or your ALDI shop.\nDuring our presentation, we invite the audience to delve into the fascinating world of motorising random objects and the art of upcycling, along with the myriad challenges we encountered along the way. From designing our own lithium-polymer batteries to countless iterations and rigorous testing, we'll discuss the intricacies of dealing with electromagnetic interference, experimenting with various motor controllers, and even designing our own from scratch. We want people to experience the shenanigans we went through and the fun we had along the way to hopefully get more people into whacky-wheeled…..wehicles.\nBut it's not all talk! We're excited to demonstrate the trolley live, allowing you to experience first-hand the joy and sheer mayhem it brings. Our goal is to inspire you to embark on your own wacky-wheeled adventures, learning from our missteps and benefiting from our advice and tips.\nNo Project is ever truly done lastly we want to look into the future: The intended use cases and how we aim to share our knowledge and plans with the wider community. Our commitment to openness and collaboration means that anyone bold enough to motorise anything around them can benefit from our experiences and insights.\n\nLicensed to the public under https://creativecommons.org/licenses/by-sa/4.0/","original_language":"eng","persons":["Hendrik","Gwen and Callum"],"tags":["421","emf2024","talk","Stage C","2024","Day 2"],"view_count":90,"promoted":false,"date":"2024-05-31T15:40:00.000+02:00","release_date":"2024-11-20T00:00:00.000+01:00","updated_at":"2026-03-21T20:00:05.154+01:00","length":1595,"duration":1595,"thumb_url":"https://static.media.ccc.de/media/events/emf/2024/421-755cf314-5edc-50cb-bc1a-ff7ce5387ce0.jpg","poster_url":"https://static.media.ccc.de/media/events/emf/2024/421-755cf314-5edc-50cb-bc1a-ff7ce5387ce0_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/emf/2024/421-755cf314-5edc-50cb-bc1a-ff7ce5387ce0.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/emf/2024/421-755cf314-5edc-50cb-bc1a-ff7ce5387ce0.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/emf2024-421-remote-controlled-chaos-cart-how-to-motorise-trash","url":"https://api.media.ccc.de/public/events/755cf314-5edc-50cb-bc1a-ff7ce5387ce0","conference_title":"Electromagnetic Field 2024","conference_url":"https://api.media.ccc.de/public/conferences/emf2024","related":[]},{"guid":"3768e758-9ea4-54f2-8f6b-eb92c20f9842","title":"CERN Technology: Following the White Rabbit down a 27km hole.","subtitle":null,"slug":"emf2024-181-cern-technology-following-the-white-rabbit-down-a-27km-hole","link":"https://www.emfcamp.org/schedule/2024/181-cern-technology-following-the-white-rabbit-down-a-27km-hole","description":"How does the most complicated machine in the world work?

Inspired by the film \"Don't Look Up\", where Benn produced the impact campaign, we will explore this dynamic together. When the ethics are no longer focused on being accurate, but rather being first,and being attention grabbing, it becomes difficult for people to discern what is and is not an important story. So we wonder how some of the most important stories either fall through the ether entirely, or are seen and dismissed by the apparatus of the 24 hour news cycle and 3 second refresh feeds. That's what films like Don't Look Up tackle so well.\n\nBenn is a SXSW Grand Jury Prize \u0026 UNICEF Prize winning, Oscar Shortlisted, Webby nominated producer.

Mobile phones can sort-of do this, but they manage by listening to the cell towers, so this won't work everywhere. \"Radio controlled\" clocks just listen to a low frequency broadcast, there's a few different transmissions across the world but they're incompatible and know nothing of time zones. Desktop computers can use the internet for time, but you still have to tell it what zone you're in.\n\nReally, it should be possible to build a clock with nothing more than a GPS receiver, which figures out the time on its own, with no need for internet or cellular connection. It turns out that doing this requires an on-board world atlas, a spherical coordinate point-in-polygon algorithm, and a complete database of offsets and daylight savings rules.\n\nI finally created a clock that automatically corrects itself as you carry it across country and timezone borders. The journey to this point was so ridiculously tedious that it borders on the absurd.

Why, today, do the number of female directors hover around the 10% mark, even after #MeToo and #TimesUp? Female A-list stars still earn only about half as much as their male counterparts, partly because only about 12% of leading roles go to women.

Satellites, of course! After facing dilemmas of tracking the staff shuttles at a major UK festival, we decided to look at other options and discovered some cheap Iridium satellite constellation hardware on eBay. When they arrived, we surveyed what we had purchased, discovered it was ex-Ministry of Defense hardware, and hasn’t been scrubbed properly. After getting a new pair of trousers and making the relevant disclosures, we worked to reverse engineer the hardware and get some usable data transmitting into space (and back down).\n\nThis involved dumping the firmware of the chip, and stepping bit-by-bit through the memory to understand what was happening, as well as a few casual emails to defence contractors. Getting airtime for satellite hardware was also a challenge, and working around the intricacies of Iridium Short Burst Data. Furthermore, we’ve developed the concept into an interactive map that overlays the realtime position of the tracker, and gives speed and heading data.\n\nLicensed to the public under https://creativecommons.org/licenses/by-sa/4.0/","original_language":"eng","persons":["Blue and Q"],"tags":["90","2024","emf2024","talk","Stage A","emf2024-eng","Day 3"],"view_count":714,"promoted":false,"date":"2024-06-01T11:00:00.000+02:00","release_date":"2025-05-29T00:00:00.000+02:00","updated_at":"2026-04-04T03:00:02.681+02:00","length":1399,"duration":1399,"thumb_url":"https://static.media.ccc.de/media/events/emf/2024/90-10a4082e-375f-587f-918f-038b0e1be5fc.jpg","poster_url":"https://static.media.ccc.de/media/events/emf/2024/90-10a4082e-375f-587f-918f-038b0e1be5fc_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/emf/2024/90-10a4082e-375f-587f-918f-038b0e1be5fc.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/emf/2024/90-10a4082e-375f-587f-918f-038b0e1be5fc.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/emf2024-90-adventures-with-iridium","url":"https://api.media.ccc.de/public/events/10a4082e-375f-587f-918f-038b0e1be5fc","conference_title":"Electromagnetic Field 2024","conference_url":"https://api.media.ccc.de/public/conferences/emf2024","related":[]},{"guid":"df2d2579-3184-55cf-acb3-b6b31d7ffb0b","title":"Does Robot Wars have a Meta?","subtitle":null,"slug":"emf2024-134-does-robot-wars-have-a-meta","link":"https://www.emfcamp.org/schedule/2024/134-does-robot-wars-have-a-meta","description":"Robot Wars is a TV show that inspired a generation of engineers to take up the sport of \"Robot Combat\", but what drove success in the design of those competing? \n\nLooking at some famous matches and designs, this talk will break down the rock-paper-scissors of the sport, and try to provide an understanding of how this can help to educate a new generation of engineers today. \n\nShould the sport have a Meta, it will mean certain designs always win out over others - however should it not, then it may suggest it is not the design itself that determines success, but rather ones understanding of design.","original_language":"eng","persons":["Gareth Anstee"],"tags":["134","emf2024","talk","Stage B","2024","Day 4"],"view_count":115,"promoted":false,"date":"2024-06-02T16:30:00.000+02:00","release_date":"2024-08-31T00:00:00.000+02:00","updated_at":"2026-04-04T03:15:02.626+02:00","length":1560,"duration":1560,"thumb_url":"https://static.media.ccc.de/media/events/emf/2024/134-df2d2579-3184-55cf-acb3-b6b31d7ffb0b.jpg","poster_url":"https://static.media.ccc.de/media/events/emf/2024/134-df2d2579-3184-55cf-acb3-b6b31d7ffb0b_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/emf/2024/134-df2d2579-3184-55cf-acb3-b6b31d7ffb0b.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/emf/2024/134-df2d2579-3184-55cf-acb3-b6b31d7ffb0b.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/emf2024-134-does-robot-wars-have-a-meta","url":"https://api.media.ccc.de/public/events/df2d2579-3184-55cf-acb3-b6b31d7ffb0b","conference_title":"Electromagnetic Field 2024","conference_url":"https://api.media.ccc.de/public/conferences/emf2024","related":[]},{"guid":"f486d9c6-bb8f-56b3-ae5e-e27435239cdb","title":"OMG WTF SSO: A beginner's guide to Single Sign-On (mis)configuration","subtitle":null,"slug":"emf2024-233-omg-wtf-sso","link":"https://www.emfcamp.org/schedule/2024/233-omg-wtf-sso","description":"Single Sign-On (SSO) is sold as a way to\n•\tcentralize managing your organization’s users,\n•\tmake life easier for your colleagues, and\n•\tenforce consistent security standards.\nBut SSO protocols are just ways for an identity provider to share information about an authenticated identity with another service. Me having a way to tell my vendor “yeah, that’s Bob” doesn’t tell me what the vendor does with this information, or if the vendor always asks me who’s coming in the door.\nA bad SSO implementation can make you think you’re safer, while hiding all the new and fun things that have gone wrong.\nTo get the most out of implementing SSO, I need to know what I’m trying to accomplish and what steps I need to follow to get there. To illustrate why SSO needs to be set up carefully, for each of the things you need to do right, I’ll give you some fun examples of creative ways you and your vendor can do this wrong. We all learn from failure, right???\nI’m sharing this info because this year I got deeply involved in the SSO setup for several vendors at work. It turns out that I’m good at asking weird questions, and it’s an extremely valuable thing to do. If you know how things should be, then you know where they could be broken, and you can ask your vendors (and your colleagues!) “weird questions” before an adversary does.","original_language":"eng","persons":["Adina Bogert-O'Brien"],"tags":["233","emf2024","talk","Stage C","2024","Day 3"],"view_count":213,"promoted":false,"date":"2024-06-01T11:30:00.000+02:00","release_date":"2024-08-31T00:00:00.000+02:00","updated_at":"2026-03-26T16:15:07.115+01:00","length":1761,"duration":1761,"thumb_url":"https://static.media.ccc.de/media/events/emf/2024/233-f486d9c6-bb8f-56b3-ae5e-e27435239cdb.jpg","poster_url":"https://static.media.ccc.de/media/events/emf/2024/233-f486d9c6-bb8f-56b3-ae5e-e27435239cdb_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/emf/2024/233-f486d9c6-bb8f-56b3-ae5e-e27435239cdb.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/emf/2024/233-f486d9c6-bb8f-56b3-ae5e-e27435239cdb.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/emf2024-233-omg-wtf-sso","url":"https://api.media.ccc.de/public/events/f486d9c6-bb8f-56b3-ae5e-e27435239cdb","conference_title":"Electromagnetic Field 2024","conference_url":"https://api.media.ccc.de/public/conferences/emf2024","related":[]},{"guid":"cd8cfb05-8e1a-53cf-ab22-297e006a3d12","title":"Run your own fucking infrastructure - 2024 edition","subtitle":null,"slug":"emf2024-24-run-your-own-fucking-infrastructure-2024-edition","link":"https://www.emfcamp.org/schedule/2024/24-run-your-own-fucking-infrastructure-2024-edition","description":"In a 2012 talk about running your own infrastructure I made some predictions on the future and made some claims.

How we allayed security concerns. What went wrong. How we dealt with trolls. And why it was so important to be as transparent as possible.\n\nThis talk asks if we did the right thing? Should have done something differently? Could we have been more open? Were the risks justified? Was being Open Source a help or hindrance?\n\nThis is a personal recollection of a very strange period in health-tech history.\n\nLicensed to the public under https://creativecommons.org/licenses/by-sa/4.0/","original_language":"eng","persons":["Terence Eden"],"tags":["16","emf2024","talk","Stage A","2024","Day 4"],"view_count":103,"promoted":false,"date":"2024-06-02T11:00:00.000+02:00","release_date":"2024-11-19T00:00:00.000+01:00","updated_at":"2026-04-03T15:15:03.428+02:00","length":1557,"duration":1557,"thumb_url":"https://static.media.ccc.de/media/events/emf/2024/16-7efce2d6-3214-50c0-827a-bbc7f16366f7.jpg","poster_url":"https://static.media.ccc.de/media/events/emf/2024/16-7efce2d6-3214-50c0-827a-bbc7f16366f7_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/emf/2024/16-7efce2d6-3214-50c0-827a-bbc7f16366f7.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/emf/2024/16-7efce2d6-3214-50c0-827a-bbc7f16366f7.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/emf2024-16-lessons-learned-open-sourcing-the-uks-covid-tracing-app","url":"https://api.media.ccc.de/public/events/7efce2d6-3214-50c0-827a-bbc7f16366f7","conference_title":"Electromagnetic Field 2024","conference_url":"https://api.media.ccc.de/public/conferences/emf2024","related":[]},{"guid":"04795634-2cdf-51da-a0d6-15440e6c6fb6","title":"Infrastructure Review","subtitle":null,"slug":"emf2024-552-infrastructure-review","link":"https://www.emfcamp.org/schedule/2024/552-infrastructure-review","description":"Members of the EMF infrastructure teams (network, power, lighting, video, telephony) will talk about how we made the event happen this year.

Many of them are built to a rather high quality, and best of all, they can still be found for not a lot of money.\n\nYou can still buy the film, and it's a lot of fun shooting a real movie, but it's not cheap. Wouldn't it be great if you could drop in a digital cartridge instead for modern day digital video with a retro feel! This project started in early 2023, and this will be its first outing in front of a live audience.\n\nLicensed to the public under https://creativecommons.org/licenses/by-sa/4.0/","original_language":"eng","persons":["Jenny List"],"tags":["431","emf2024","talk","Stage B","2024","Day 4"],"view_count":121,"promoted":false,"date":"2024-06-02T12:50:00.000+02:00","release_date":"2024-11-30T00:00:00.000+01:00","updated_at":"2026-03-31T13:30:06.141+02:00","length":1446,"duration":1446,"thumb_url":"https://static.media.ccc.de/media/events/emf/2024/431-76e3ea07-8402-5d69-927d-1fabbabb50b5.jpg","poster_url":"https://static.media.ccc.de/media/events/emf/2024/431-76e3ea07-8402-5d69-927d-1fabbabb50b5_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/emf/2024/431-76e3ea07-8402-5d69-927d-1fabbabb50b5.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/emf/2024/431-76e3ea07-8402-5d69-927d-1fabbabb50b5.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/emf2024-431-bringing-any-super-8-camera-into-the-digital-age","url":"https://api.media.ccc.de/public/events/76e3ea07-8402-5d69-927d-1fabbabb50b5","conference_title":"Electromagnetic Field 2024","conference_url":"https://api.media.ccc.de/public/conferences/emf2024","related":[]}]}
