Dubstep Carrots - your gateway vegetable to accessible music making (emf2026)
3w ago00:32:34Tap to summarizeDo we decide if we can play an instrument before we've even seen it? How much of our self-belief about our musicianship is based on adverse childhood experiences with cheap conventional instruments? How can we break through this barrier and rediscover the joy of noise, sound and musical play by shifting the idea of what constitutes a musical instrument? Join us as we explore new ways of making music and sound with interfaces created from root vegetables, recycled materials and willing human test subjects in front of a live studio audience. Using a range of sensors, interfaces and microcomputers, we will explore accessible ways of making music and discuss why this matters so much for those who face disabling barriers when using conventional instruments. Sometimes, the best musical instrument is a carrot... join us to find out why.

They Forgot What Happened Last Time: hacking the Windows 365 Link (emf2026)
3w ago00:13:39Tap to summarizeThe Windows 365 Link is a thin client, running a special edition of Windows 11, that can only connect to a "Windows 365 Cloud PC" and is otherwise useless ewaste. When it was announced, Microsoft boasted its total vendor lock-in plan, which they described as "secure-by-design architecture": no admin rights, no local data, EFI Secure Boot locked on, BitLocker always enabled. The last time EFI Secure Boot was locked on was Windows RT devices, and that caused me to personally break the Windows bootloader chain of trust, several times. Challenge accepted.

Project CETI: How to Decode the Language of Other Species (emf2026)
3w ago00:30:09Tap to summarizeProject CETI is an interdisciplinary research project that uses new techniques in data collection, analysis, and artificial intelligence to understand what sperm whales are saying to each other. The project includes researchers from multiple universities and institutions around the world, spanning disciplines across marine biology, robotics, cryptography, artificial intelligence, and more. This talk will give an overview of our aims and plans and highlight some of our most exciting breakthroughs - including identifying sperm whale 'vowels', and capturing the first ever audio/video recording of a sperm whale birth. We'll also discuss our approach to responsibility and ethics when it comes to use of technology to engage with other species.

SMolSTM: an open hardware scanning tunnelling microscope for creating single-molecule circuits (emf2026)
3w ago00:18:12Tap to summarizeAs the energy consumed by datacentres grows, finding energy-efficient alternatives to conventional electronics becomes increasingly urgent. Molecular electronics offers a different idea of what a device can be: using synthetic chemistry, custom molecules can be designed for specific applications, utilising fascinating nanoscale phenomena such as quantum interference. These single-molecule devices can “self-assemble” into larger structures for energy-efficient sensing, memory, and computation. The nanostructured nature of single molecules offers endless possibilities, and difficulties: wiring molecules into circuits requires sub-nanometer (< 0.000000001 m!!!) precision. The scanning tunnelling microscope (STM), which explores surfaces at the atomic scale using quantum tunnelling, could become the multimeter of molecular electronics, but commercial STMs are extremely expensive and not optimised for these experiments. This talk describes the development of an open-hardware STM for single-molecule “break-junction” experiments (SMolSTM). The design was developed over several years, from a prototype built in a shed during the COVID-19 pandemic to a precision instrument currently in use in a state-of-the-art low noise research facility. This STM is orders of magnitude less expensive than commercial alternatives and can be made using hand tools and 3D printing, yet achieves exceptional performance in single-molecule experiments. The flexibility of open hardware allows experiments which are impossible on existing systems. This talk will introduce molecular electronics, outline a multi-year journey in DIY STM development, and describe some experiments using SMolSTM (e.g. measuring the resistance of a single gold atom!). This work was conducted in part at Lancaster University as part of an EPSRC funded research project.

Hacking APRS to warm my camper van whilst I’m still in the pub (emf2026)
3w ago00:18:10Tap to summarizeThis brief talk will describe a personal remote-control protocol that can be run over APRS and potentially other similar location messaging protocols. APRS is an amateur VHF/UHF ad-hoc, wide area, resilient digital mesh network relaying position information. Amateur APRS networks operate using AX25 packet radio at 144 & 432MHz and can have a similar range per node to UHF LoRa and Meshtastic networks. I designed this protocol to remotely operate appliances in my house or my van, all within the terms of the amateur licence, without the use of public cellular networking or Internet WiFi nodes. My requirement was for a cheap off-the-shelf means to relay data two ways from inside a pub to my camper van 2-3 miles distant. The talk will include a description of the overlay protocol and its implementation using a Raspberry Pi Zero and a cheap Baofeng handy talkie (HT). I will explain how a couple of simple Bash scripts running over Direwolf on the Pi translate my adapted APRS messages and then are used to control a wide range of electrical appliances. The talk includes a demonstration of remote control of a couple of units in my van which is located some distance away. The talk will focus on APRS, and a theoretical and practical comparison will be made between APRS running over conventional AFSK and over LoRa. Other options including Meshtastic on the licence free and other frequencies will be covered.

Sonus ex nihilo (emf2026)
3w ago00:24:29Tap to summarizeJoin me on an audible journey through the history of electronic audio synthesizers. You'll learn how popular analog synths from the 1970s operate, how to change the sounds they make, as well as how the accidental discovery of FM synthesis in 1967 changed the sound of the 1980s. We'll cover oscillators, filters, resonance, and how recent chip decapping and reverse engineering efforts revealed the long-hidden tricks of clever Japanese engineers. Everything will be explained from (more or less) first principles, with live audio demos throughout to help illustrate concepts: no electronics, DSP, or music background required.

An Appreciation of Ecological Sanitation (or Turds for Nerds) (emf2026)
3w ago00:27:18Tap to summarizeOur modern sewage system relies on vast amounts of water and this causes huge problems. Perhaps the greatest being that the anaerobic microbes that break down human waste in water are inefficient, produce greenhouse gases, and then waste ends up in the rivers and seas producing algal blooms and foul smells. Whereas their descendants on land (aerobic microbes) are extremely efficient and only produce CO2, H2O and organic matter. So what went wrong? I will describe the history of the modern sewage system and how it broke the natural nutrient cycle, causing pollution, health problems and costing a lot of public money, and then conclude with the maths, chemistry and biology of a micro self-sustaining aerobic sewage system on a houseboat.

Mountains, Rescues, and Risks (emf2026)
3w ago00:29:43Tap to summarizeIt's human nature to ignore or downplay risk until it actually happens - but how do you handle it in a high-consequence environment? How do you take a situation that has already been dangerous for one person and insert ten more safely? For some reason, groups of people worldwide volunteer to do backcountry rescue - in mountains, canyons, deserts, and more. In these hostile environments, ignoring risk isn't an option; so how do we manage it, embrace it, and work with it? What does it take to turn a dangerous situation into a safer one, and what does this share with other fields where life-safety is a critical feature? How is technology both helping and hindering us? Join us for an overview of mountain rescue, mission successes, near-misses, successful failures, and why exactly a bunch of mostly-competent idiots give up a lot of their free time to pull people out of nasty situations.

The Hassle Hurdle: a philosophy to hack ADHD (emf2026)
3w ago00:24:06Tap to summarizeEight years ago a 5 second bit in a YouTube video led me to develop a generalised philosophy on how to design coping mechanisms for my ADHD: The Hassle Hurdle. Ever since then I've been continuously using and improving the philosophy to manage the symptoms of my ADHD, and my quality of life in general. In the talk I'll introduce the three rules of the philosophy, how they came about, and suggest ways of implementing them. The talk will then cover some common lessons and pitfalls that I've discovered along the way, before finishing with some recommendations of practical tools, software-based tools and finally some 'Oh no I'm too good at computers and can bypass any distraction blocking software I try' tools.

Middle Rage - Social Media and the War on Democracy (emf2026)
3w ago00:28:02Tap to summarizeWhat happens when the people we think of as “having it all sorted” start being quietly pulled towards extremism online? This talk from the SMIDGE project shines a light on an often-overlooked group: the middle aged. This includes some of the most powerful people in the world CEOs, influencers and politicians. For most however, middle-age looks very different: juggling jobs, children, ageing parents, mortgages, and a constant stream of news, advice, and opinions online. Far from being “sorted,” this stage of life is full of pressures including health worries, financial strain, and caring responsibilities. So, when something appears online that promises a clear explanation, a simple answer, or someone to blame, it can be hard not to pay attention. The problem is that the systems shaping what we see are not designed to inform us but are designed to keep us engaged. AI-driven content is becoming more convincing by the day, blurring the line between what is real and what is not. What starts as an innocent search for diet tips or money advice can lead down a path towards more extreme, emotionally charged content. Not suddenly, but step by step. This talk explores why the “invisible middle” matters both as a group vulnerable to misinformation, and as one with real influence over how ideas spread. Because if we want to understand radicalisation today, we cannot afford to ignore the middle aged.
