  • I gave up investment banking to become a digital artist (emf2022)
    As cringe as I often find it talking about myself, this seems to be the thing about my background that amazes people I mention it to.
    I spent 6 years failing to do a CS PhD, co-founded a (failed) fin-tech startup and watched the 2008 credit crunch from the inside of a multi-billion dollar hedge fund. Thanks to a chance meeting with an artist (who was hanging a door at the time), I rediscovered both my childhood love of drawing and a joy in the tech that I had started to hate.
    I'll talk about failing and reinvention; imposter syndrome; being neurodivergent; my experiences of the commercial world and the art world; finding a space in which you feel comfortable – but not *too* comfortable; and the power of collaborating.

  • Launching a Rocket, Suspended by a Balloon (Rockoon), from the Stratosphere (emf2022)
    The B2Space satellite launch solution is based on the “rockoon” concept (rocket + balloon), and will comprise of a stratospheric balloon, which will lift a self-operative platform from which the launcher is deployed. A solid propellant rocket will deliver the satellites into the required customer orbits (Within Low Earth Orbits [LEO] ), which are orbits with altitudes ranging from 200km to 1000 km, approximately).
    The talk will describe the concept and the steps taken to develop the rockoon project.

  • The Digi-Gurdy: An electronic MIDI enabled Hurdy Gurdy project (emf2022)
    The hurdy-gurdy is an ancient musical instrument (10th century) with drones and melody strings bowed by a rotating wheel, played by pressing keys which contact them at different points. It featured in TV series such as “Black Sails” and “Walking Dead” as well computer games. A major barrier is that they are very expensive at thousands of pounds each and built to order with lead times of over a year. Rather like bagpipes, they are loud. For pipers, practice e-chanters are available while nothing similar exists for the hurdy-gurdy. The Digi-Gurdy project started as a 3D printed version of the keyboard part of the instrument in isolation, with some internal electronics, for my own personal use to learn a few tunes on. After posting on Thingiverse, a website for sharing 3D printed ideas, I had many requests from people asking me to build them one. This open-source project has developed through many variations which I would bring to the talk, resulting in an all laser-cut wooden full-size hurdy gurdy design with a realistic crank handle system and a detachable playable keybox for travelling. It is an electronic device, with correctly placed keys, that outputs data via the industry standard MIDI communications system for electronic musical instruments, via a USB cable to an attached or wirelessly paired phone or iPad running suitable MIDI player software. It is a low-cost way to enter the Hurdy Gurdy world and allows practice anywhere using headphones, thus preventing eviction or divorce!

  • Automated Science at Sea - The Mayflower Autonomous Ship (emf2022)
    The Mayflower Autonomous Ship is a fully autonomous, AI powered research vessel, that will at the time of this talk will hopefully have completed its primary mission to cross the Atlantic from Plymouth UK, to Plymouth Massachusetts without any human intervention or control. The AI captain installed will guide the ship across the Atlantic, avoiding obstacles, plotting courses around the weather and balancing the many variables needed to safely cross one of the most dangerous oceans.
    As well as it's main goal to cross the Atlantic, it will also be operating a number of data collection and ocean science experiments to help researchers better understand our oceans, as well as developing new technologies to help automate science at the edge.
    This talk, will give a history of the Mayflower Autonomous Ship, a look into the exciting science conducted aboard including our Whale Song detector and Electronic Tongue, and how everything is brought together using open source and a great team.

  • A Crash Course In Railway Safety (emf2022)
    Travelling by rail in most of the world is one of the safest forms of transport you can take, and in the UK even minor collisions make the news. But it wasn't always quite that way...
    This talk will be a potted history of the safety of the railways in the UK and Ireland, starting from the early days when signalling was thought of as an inconvenience, and anything with wheels on it which sort-of went round went on the track. Eventually, the railway companies learned the benefits of adopting safer methods of working (sometimes requiring some encouragement from the law), leading to the introduction of some Victorian methods we still use today. Finally, we look at the more modern era with the railway losing its way with privatisation, and onto the current time, where computers and paperwork solve everything. Perhaps.
    Featuring: Swiss Cheese, Charles Babbage vs. Brunel, working too hard, forgetting where you put your trains, losing your religion, a dark and stormy night, drunken driving, a loose screw, shifting foundations, and more.
    No previous knowledge of the rail industry is required. The talk will cover some recent fatal accidents at a high level.

  • Authenticating open source cloud applications with LDAP (osc22)
    It is very common for businesses with small teams to use cloud services to synchronise their work, stay in touch etc. All of these can also be achieved using open source software. However, making the different open source applications to authenticate through a single mechanism is somewhat challenging.
    In this presentation, I will cover the use of LDAP to authenticate cloud services like Nextcloud and Rocket.Chat.
    I'll cover 389 Directory Server to provide the LDAP service.

  • Some Useful Maths (emf2022)
    4 lightning talks about different mathematical subjects
    1. *A tip for when to take risks in board games and in life*. I will give an insight into how Google's AlphaGo AI chooses its next move, and give an example of a game that seems biased against you, but you actually have a slight advantage.
    2. *Teaching a robot to tell jokes*. I will introduce the concept of factor graphs and describe an application of them to joke generation.
    3. *The twitter bot that is playing the longest possible game of chess*. The World Chess Federation has some rules to prevent games from going on forever. I will outline a proposal by Tom Murphy VII for the longest possible legal chess game, and show the Twitter bot that I made to celebrate this achievement.
    4. *A little theory of abundant numbers*. Abundant numbers, e.g. 12, 60, 360, are useful as they have many factors. I will show you how common these numbers are and how to find them.

  • The Atomic Gardener (emf2022)
    This talk tells the extraordinary story of Muriel Howorth - science fiction author, choreographer, gardener and amateur nuclear physicist. Far away from the cares of Britain's Atomic Weapons Establishment, Howorth worked from her home in Eastborne in the early 1960s on an astounding DIY atomic experiment. Her aim was to solve world hunger. Sarah Angliss shares rarely seen archival material as she tells Howorth's story and considers the potential of citizen science and the perils of techno fixes for complex societal problems. This event may contain references to giant mutant vegetables.

  • Inside Datatrak: resurrecting a radio navigation network (emf2022)
    It began with buying an old Datatrak navigation receiver, and ended in the reverse-engineering of an entire navigation system -- one that had been dead since 2014. A demonstration of how a 1980s navigation receiver was reverse-engineered to component level, and the structure of the network analysed to protocol level, using the data stored in the receiver's battery-backed RAM.
    Includes sections on how land (not satellite) radio navigation works, PCB reverse engineering, how old recordings of the signals were recovered, and the design of an Arduino shield to generate new Datatrak signals.
    An ongoing project of interest to PCB and software reverse engineers, and radio enthusiasts.
