Computational Thinking und digitale Handlungskompetenzen kindgerecht vermitteln – FELI an der Uni Bamberg Die Forschungsgruppe Elementarinformatik (FELI) an der Uni Bamberg möchte informatische Konzepte über die Anregung von „Wie funktioniert das?“'-Fragen vermitteln und zudem Lehrkräfte dazu befähigen, dies mit ihren Schülys zu tun. Schon Kinder lernen Computer, Smartphones, das Internet als Konsumentys kennen, als ein Angebot, das sie weitgehend passiv nutzen. Wir wollen ihnen die Fähigkeiten vermitteln, diese Technik als Werkzeug nutzen zu können, ihre Ideen umzusetzen, zu gestalten. Dazu müssen sie verstehen, wie Computer grundsätzlich funktionieren, was ein Algorithmus ist, und wieso der Rechner nicht mit dem Drucker reden kann. about this event: https://cfp.fairydust.reisen/iger-2024/talk/T3VQVG/

KI ist der neue Hype und Schulen drehen durch. Was KI in der Schule bedeutet, und warum der ganze bescheuerte Futurismus dahinter die Zukunft gefährdet, erkläre ich hier.... Die KI ist da und in der Bildung drehen alle durch. Dabei scheinen die meisten Lehrkräfte und deren Vorgesetzte nicht zu wissen, was ein LLM eigentlich tut. Und das bedeutet, dass wir vor einer Schule steht, die eine Sache will und die andere Sache tun wird, wenn wir Nerds denen nicht sagen, dass das dumm ist. about this event: https://cfp.fairydust.reisen/iger-2024/talk/RTZBE7/

There's nothing good on TV, and streaming curses you with the Paradox of Choice. So why not be Elliot Carver for a day and run your own Cable, satellite or UHF TV station - or even a whole network? With a few low-cost computer boards (Raspberry Pi's work but others are fine too) and video modulators, you can recreate the wonders of 1990s Cable TV in your own home, flat, or living room. I'll also talk about going further and how I recovered and resurrected a General Instrument ACC-4000 headend controller PC and used it to configure a small fleet of cable boxes.

Ever wondered about what's behind large advertising billboards? Interested in pretty blinking lights? Curious about electronics and circuit board design? This talk might be for you! Our hackspace recently got a donation of ~800 LED matrix panels (squares with lots of tiny LEDs on them), with little in the way of documentation. I'll explain how they work, how we got them to light up and display things, and how to make it fast enough to display 30fps video -- all with commodity parts that cost less than 20 pounds. We'll explore the weird and wonderful world of poorly translated datasheets and control software, marvel at the library of weird glitched-out images I ended up with on the road to success, and dive into the strange but extremely useful Programmable I/O block of the RP2040 microcontroller. If the stars align, you'll be able to see everything working on a real demonstration panel, too! Although we'll be going into detail on some bits, this talk should be accessible to most audiences. about this event: https://www.emfcamp.org/schedule/2024/199-driving-fancy-led-panels-with-commodity-hardware

You have an object / art installation/auction purchase and want it somewhere else? What are the options of getting it there without breaking yourself? This will be a short, hopefully entertaining, overview of transport options, their financial and environmental impact and the time they take. This talk is based on examples of personal experience sending hacky art installations around Europe and the globe. By doing this many questions had to be answered for example: - how big are doors? - why acessability regulayions are great or not? - what fits in an elevator? - how much fits in a van? - what fit’s in a cargo aeroplane? There will be dragons! Along the way we’ll encounter customs officers, new excitement around rules for international road haulage, air freight and how astronomically long container shipping takes.

A talk about the difficulties of geospatial analysis when the country you are interested is on the edge of the world map. We'll go over some background before showing what happens when you try and draw a box around this country and the issues this causes everyone from blury satellite views to navigation failing. And why it happens. The east and west edge of the classic Eurocentric world map, with the prime meridian down the middle, are both the same place, this causes some interesting effects.

It has been 30 years since Private Eye released this biting satire of the privatisation of British Rail. Today, the railway system is now part public part private, leaving plenty of confusion for passengers. Who runs your local station? Who sets the rail fares, and who covers your refund? And where the hell does HS1 and HS2 fit into all this? I will take you through how the UK rail organisations are structured, who does and owns what, and how does this affect passengers? - What's the difference between Network Rail and National Rail? - How does split ticketing work? - What did Labour announce in April? And most importantly: Who should I be angry at when I'm crammed in sideways on a delayed Sunday afternoon train to Leeds? No knowledge of the rail industry is required to enjoy this talk, but experts will find it depressing. I may swear, mostly about MPs.

A talk about the state of the art with metal 3D printing, and how it can let you make rocket engines much more cheaply and quickly than ever before. I will briefly describe the anatomy of a rocket engine and why the extreme conditions it must endure make designing one hard, and then introduce powder metal 3D printing and how you print an engine. I work for a company in this field, and I will show various images and videos of our engines being fired, as well as the engines themselves so that people can have a look, and some samples with internal cutaways to show the internal structures that 3D printing technology now makes relatively easy. I will also discuss drawbacks and common failure-modes of 3D printing for rocket engines, and talk about where new advances in the field might take us, such as multi-metal prints, hybrid machining, and other exciting technologies. about this event: https://www.emfcamp.org/schedule/2024/131-how-to-3d-print-a-rocket-engine

Most technical people hear about fusion power in the news or see it in games and movies, and are familiar with the joke that it's always 20 years away. Beyond this, it's surprisingly rare to find good information beyond the basic physics and the marketing promise of unlimited, clean energy. As 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. Coming 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. about this event: https://www.emfcamp.org/schedule/2024/471-unlimited-power

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. It looks at what the project was for, how it was designed, what went wrong, and why. Swiss cheese is a way of conceptualizing accidents, and the explosion is used so show how this works. Hopefully by the end, everyone will have heard about a facinating case study in bad project management, weird critical infrastructure, and have recieved a safety talk by stealth. about this event: https://www.emfcamp.org/schedule/2024/97-explosion-in-a-tunnel-understanding-swiss-cheese

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? Looking 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. Should 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. about this event: https://www.emfcamp.org/schedule/2024/134-does-robot-wars-have-a-meta

The British rail industry publishes a lot of open data: there's at least 18 distinct data sources, plus the ones I'm forgetting. This'll be a whirlwind tour of most or all of those sources, with a view at helping people who would be interested in playing with train data but don't know where to start. You'll (hopefully) leave with some ideas for what you could build (if you didn't already have some), know what data sources you'd need, and have enough context to understand those sources' documentation. I will assume software experience (ie there'll be slides with JSON, XML, and various less pleasant things) but not rail experience.

The canals of the UK have undergone transformation from industry to decay to leisure and in recent years to housing. In this talk, we'll go through some of the history of this modern day shanty town along with lessons for any budding boaters considering life on the cut. We'll cover the fundamentals of boat life including legality, work from home challenges, common pitfalls new boaters can face along with everything you need to know if boat life could work for you! about this event: https://www.emfcamp.org/schedule/2024/156-living-on-the-canals-of-the-uk-lessons-from-the-water

How do you get several three storey Cornish beam engines, a collection of Grade I listed buildings and a whole network of steam infrastructure on the path towards net zero? This talk is the experience of a volunteer on the practical challenges met whilst helping the London Museum of Water and Steam with several major projects. Expect tales of reverse engineering boiler control system ladder logic, interfacing raspberryPis to 100psi steam lines and working out the water/gas/steam usage to run 200-year old steam water pumps.

“Could you crash the Moon into the Earth?” “If the Sun explodes, would we all get vaporized?” “What’s the weather like on Mercury?” Discover the answers to these questions (and many more!) at "Astrophysics for Supervillains"! Facts about space are all well and good but discovering that if you threw someone into a black hole, they would be spaghettified – stretched out long and thin before getting squashed smaller than an atom – is truly, fascinatingly gruesome. This quirky space talk will teach children about the solar system, galaxies, the universe, and, most importantly, the answer to the question “Which planet is entirely populated by robots?”. about this event: https://www.emfcamp.org/schedule/2024/428-astrophysics-for-supervillains

"So what do you do?" Everything. ────────── As a kid I couldn't decide what I wanted to be when I grew up. I still can't, but over the past twenty years I've turned that into a superpower. In this talk I'll tell you how I hacked the idea of a standard career and managed to combine skills from different fields and specialties, leading to some unique roles and opportunities. If you love learning and constantly adding new tools to your intellectual toolkit, you’ll find that being a 'nerd of all trades' is not just fun—it’s the best way to live. The only downside? When someone asks "so what do you do" at parties, you'll never quite know what to say!

Technologists are wizards. Today, we wield the power to effect changes from a tent, a bedroom or an office the likes of which fifty years ago one might need the power of a small nation-state to accomplish. Having seen these systems from all angles - building the tech, researching digital consent academically, and fighting biased public sector algorithms in the media and the courts - I'm confident that we really haven’t adapted to that reality. In the choices we make in technical practice, we find ourselves paving the road to hell with our good intentions. Most of us aren't trained in ethics, policy or politics - so how do we manage the weighty burden of being responsible for people’s safety? What can we do – both as individuals and as a society as a whole – to try and stop algorithmic harms? And, how do we stop our robots from killing us? about this event: https://www.emfcamp.org/schedule/2024/355-dont-be-evil-by-accident-algorithmic-harms-and-ethics

How does the most complicated machine in the world work? Why should we pay 16 billion euros to keep some physicists happy with a new toy? What has CERN ever done for us? What happens when you lose control of a beam the size of spaghetti with the energy of a full express train? This talk, delivered by a beam instrumentation engineer at CERN, will introduce CERN and it's accelerator complex, and discuss the technology required to deliver one petabyte of cutting-edge science per day to over 170 research facilities in 36 countries. The talk will also cover some of CERN's open source software and hardware contributions to date, and finally explore their science and technology roadmap for the coming years. about this event: https://www.emfcamp.org/schedule/2024/181-cern-technology-following-the-white-rabbit-down-a-27km-hole
