Four weeks from today the Hackaday Superconference comes alive for the fifth year. From engineering in challenging environments to elevating the art form of electronics, here are nine more talks that will make this a year to remember.

In addition to the slate of speakers below there are three other announcements, plus workshops. Jeroen Domburg (aka Sprite_TM) is designing this year’s badge based around a beefy FPGA running a RISC-V core and using open source synthesis tools. We’ll have more on that soon, but if you just can’t wait, check out the expansion board spec he just published, and join the conference chat room for the inside track. Badge hacking is sure to be the liveliest we’ve ever seen.

Tickets are sold out but you can still get on the waiting list and hope that one becomes available. If you are holding onto one of these hot commodities but are unable to use it, please return your ticket so that we can get it to someone waiting with their fingers crossed.

  When it Rains, It Pours

  Over the last two years my work has been beyond ordinary, building and prototyping in strange locations like being stranded on a sailboat in the Atlantic Ocean, teaching US Marines in Kuwait, and building fuel gauge sensors for generators for vital systems in North Carolina post hurricane Florence. Some of the big lessons I’ve learned are about how to source materials and supplies in weird places, like finding potentiometers in the backwoods of North Carolina when Amazon cannot physically deliver across flooded highways, how to find welding gas in Kuwait City (and how a local chef could possibly be your best bet), or how far you can get with an O’Reilly’s Auto Parts store near the city docks. These situations help you really see the “engineer creep” that can happen to a project. I’ve learned that when you’re in high-risk situations, you really should stop caring about whether the edges of your 3D print are chamfered. In fact, version 1 of the hurricane fuel gauge sensor was demonstrated while being housed inside an elegant, tasteful sandwich baggie.

  Building Whimsical Wearables: Leveling Up Through Playful Prototyping

  Whether it’s for a theme party, Halloween, cosplay, or That Thing in The Desert, designing wearables for whimsical self expression presents a great opportunity to challenge yourself as a maker, wearer, and collaborator. As an artist and designer who crash landed into a career in tech, I’ve found that imposter syndrome can often place limits on what feels personally achievable from an electronics and programming standpoint. Recontextualizing a project to shift the focus from ‘wearable tech hardware endeavor’ to ‘quirky mixed media experiment in personal styling’, I’ve created a safe space to play and try new things just outside my skill set and produced some of my most technically complex and polished personal work. Take a journey with me through the process of conceptualizing and building my Color Stealing Fairy project, an exercise in iterative design and upgrading an interactive wearable project over the course of two years and counting.

  Software-Defined Everything

  The popularity of Software-Defined Radio (SDR) has led to the emergence of powerful open source software tools such as GNU Radio that enable rapid development of real-time Digital Signal Processing (DSP) techniques. We’ve used these tools for both radio and non-radio applications such as audio and infrared, and now we are finding them tremendously useful for diverse sensors and actuators that can benefit from DSP. In this talk we’ll show how we use the open source GreatFET platform to rapidly develop an SDR-like approach to just about anything.

  “Hacking Nature’s Musicians” (or, “The Art of Electronic Naturalism”)

  The general lack of acceptance of electronic art results from a scarcity of critics, curators, collectors, and grantors who understand electronic media, compounded by a cultural gap between the artistic and engineering communities. In order to solve this problem, we must stretch our comfort zone and vocabularies to have a respectful, enlightening conversation with people with different educational backgrounds. In this talk I’ll discuss my wonderment at the simple, analog circuit designs that mimic life-like behavior such as chirping crickets and singing birds. This will include discussion of various schematics and demonstrations of a small. along with an abbreviated survey of my work to-date.

  Jasmine Brackett

  Setting your Electronics Free

  In this panel we’ll discuss the key ways to get your projects from your workshop into the hands of the first few users, and what you can do to scale up from there. We’ll talk about common pitfalls, and also what are the best resources to draw upon.

  MicroFPGA – The Coming Revolution in Small Electronics

  Big FPGA’s are awesome. They’re doing what they’ve always done, enabling AI, signal processing, military applications etc. However, there is a new possibility emerging – FPGA’s for small applications – which is quite possibly even more significant. Using open source tools, cheap flexible development boards, and new libraries, designers have a whole new set of options, creating incredibly high performance, flexible, low power projects and products.

  Boggling the Boardhouse: Designing 3D Structures, Circuits, and Sensors from PCBs

  The presentation will be a series of design features or techniques with a few minutes of exploration into the ‘gotchas’ of each, as well as example layouts in EAGLE and physical examples. I’d like to cover as many different techniques as I can cram into 30 minutes, including bringing weird shapes into EDA, the inside corner problem caused by tab and slot, fillet soldering, stacking boards, imitating model sprues with mouse bites, manipulating the mask layer for custom displays, bendy tab buttons, working rotary encoder, and ergonomic design for handheld PCBs.

  Ted Yapo

  Towards an Open-Source Multi-GHz Sampling Oscilloscope

  Tektronix designed a 14.5 GHz sampling oscilloscope in 1968. With the easy multi-layer PCB designs, tiny surface-mount parts, blazingly fast semiconductors, and computer horsepower available to the individual designer today, can a similar sampling head be re-created inexpensively with common, off-the-shelf components? Should be easy, right? It’s not. In this talk, I’ll discuss progress towards an open-source GHz+ sampling oscilloscope, including a lot of dead ends, plus some very promising leads.

  Jeroen Domburg

  Building the Hackaday Superconference Badge

  The tradition of the Hackaday Supercon badge is to build something unlike any Supercon badge that came before. This year’s badge has an FPGA as its central component, and this comes with some extra challenges: the FPGA only comes in a BGA package with a whopping 381 pads to solder, and instead of just referring to the datasheet of the SoC to write the badge software, the SoC itself had to be written first.  I will discuss the development process of the badge, as well as the many challenges encountered along the way.

Keep Your Eye on Hackaday for the Livestream

The speakers you’ll see at Supercon have an amazing wealth of experience and we can’t wait to see their talks. But even if you couldn’t get a ticket, that doesn’t mean you have to miss out. Keep your eye on Hackaday for a link to the livestream which will begin on Saturday, November 16th.

The tickets have sold out even as the list of incredible speakers grows. Today we bring you the third dose of talks you’ll see at the Hackaday Superconference in November — whether you were lucky enough to grab a ticket, or will be watching the livestream, these eight will be speaking on topics from algorithmically-augmented live music performance to the hardware that captures the real world for display in VR and from leveraging the power of lookup tables to harnessing our engineering talent in a way that truly enriches humanity.

If you missed the two speaker announcements that have already come out, go back and take a look at those as well as the workshops being held during Supercon.

The Talks (Part Three of Many)

• 
  

  Mitch Altman

  The Pros and Cons of Tech. Can We Design Tech that Serves Humanity

  Technology is truly awesome! It is also a lot of fun. With the tools we, as humans, have made through the eons, we’ve become top-dog on our planet. But, at a great cost. It is mostly accepted that we have only 5 years to reverse climate change. How long till we no longer have any privacy. We have little time for anything but work because of all of our addictive and alienating “time-saving” devices we voluntarily choose to have in our lives. People report being less happy each decade. Soon, only 2% of the world’s wealth will be concentrated in only 0.1% of the population. The military uses anything and everything we create to spy, destroy, and kill for profit. This is not a pretty picture. What can we do? Is it possible to create technology to improve our lives? In this inspirational talk I will use personal experience to explore aspects of this important discussion.

  Creating with the Machine: Algorithmic Composition for Live Performances

  In a live concert setting, the movement and energy of performers add an important emotional element to the audience’s listening experience. Computer-generated music can achieve unique sounds and precise technique not possible by human musicians, yet it can feel alienating and impersonal due to a lack of human connection and spontaneity. “Creating with the Machine” is a set of compositions that combine algorithmic and traditional methods of music composition into live performances to explore how interactive generative algorithms can influence creativity in musical improvisation, and create a compelling listening experience for the audience. In this talk, I will introduce techniques for creating a meaningful data representation of a musician’s performance, and methods for using this input data to control a closed loop algorithmic composition.

  Beyond Blinky – Developing Retro-Games for PCB Badgess

  So, you’ve done some badge coding, maybe using Arduino, and are looking for the next step to write interactive games using a TFT screen and some buttons and sensors? Using the open-source for the Lunar Lander badge (built for DEF CON 27) I will explain how we created the framework and how you can adapt it to write your own games for this badge or for your own conference badge. We’ll step through the process for developing a new game, and discuss some of the challenges we had in creating the Lunar Lander game.

  Scrounging, Sipping, and Seeing Power

  Powering low power and ultra-low power systems is more about system design than circuit design. Selecting the right power source, using the power effectively, and then validating that the power numbers are as expected is critical at an early stage since changes may trigger a system redesign (or product failure). I will review some of the typical design decisions to make, some general back-of-the-envelope figures, and some techniques on how to plan the power use and validate a prototype. We’ll discuss questions like: How can I decide if I should be on a primary battery, solar, or kinetic energy system? How can I estimate the total usable energy from a solar panel given real-world conditions? Do I need MPPT? And how can I estimate my total energy consumption?

  How to become a manufacturing engineer in your spare time

  It’s one thing to prototype something for yourself, and entirely another to productionize a product for manufacturing. This talk is about my quest to become a manufacturing engineer. In the summer of 2016, I decided that I would do software at scale at my full time job, and hardware and objects at scale in my spare time. Since then, I’ve worked on many personal projects to get the intuitive physical feel for how things are made while documenting what I’ve learned, started writing about manufacturing for Supplyframe Hardware allowing me to tour factories and interview manufacturers, and started working part-time as a manufacturing engineer.

  Beyond the Rectangle: Building Cameras for the Immersive Future

  Ever since the earliest days of photography, we’ve tried to capture and play back the world around us. Today, immersive technologies like AR and VR are pushing beyond the 2D image, seeking to replicate more and more of the human experience. This is driving growth in new imaging, sensory, and display technologies.

• Learn about some cameras I’ve made, trends in camera technology, and how building the Matrix is hard.

  Supercharge Your Hardware (Old and New) with CircuitPython

  CircuitPython makes programming hardware easier than ever by bringing the popular Python language to modern, inexpensive 32-bit microcontrollers. This doesn’t need to be limited to modern hardware though. By pairing a modern microcontroller running CircuitPython and a vintage computer, such as a GameBoy or Yamaha piano keyboard, you can unlock the unique characteristics of these vintage devices. In this talk, you’ll learn the basics of how CircuitPython makes coding easy, how it works under the hood, and how to extend CircuitPython with C. As an example, we’ll supercharge a Nintendo’s GameBoy with CircuitPython. By the end of the talk, you’ll be able to supercharge your own hardware project with CircuitPython.

  Accomplishing the Impossible with LUTs.

• I’ve done some very bizarre and extreme things with microcontrollers over the last several years. From bit-banging (Tx and Rx) Ethernet on an ATtiny85 broadcasting video from an ESP8266 GPIO pin to writing USB stacks for chips that don’t have them, the most insane and counter-intuitive projects that have been successes have all had one thing in common. At the heart of the project is one or more lookup tables (LUTs). In computer science classes, we study algorithms like Dynamic Programming and we hear about LUTs, but we rarely discuss the true power of this game-changing tool. In this talk I will explore how to reform complicated problems in such a way to do processing faster and on smaller processors than you ever thought possible.

See You at Supercon!

We’re so excited to see everyone at Supercon this year. As mentioned above, tickets are sold out so if something comes up and you can’t make it, please request a ticket refund so we can make your spot available to people on the waitlist.

You’re going to love the talks at the Hackaday Superconference this November. The ultimate hardware conference is all about hardware creation. The ten speakers below join the talks we announced last week and that’s still not even half of what you’ll see on the stages of Supercon. Add to that the superb workshops we announced early this week and you begin to ask yourself just how much awesome can really fit into a single weekend. Well, it’s three full days and we’d recommend arriving the day before for the unofficial festivities too!

Of course, you’ll need a ticket to ride. At the time of writing there were some available (we’ve left the teens and are headed for single digits), but no guarantee there will be any left when this article is published. We’ll be maintaining a waiting list though, so if you’re sitting on a ticket you just can’t use, please return it so someone else can take your spot.

Enough delay, let’s see what talks await us at 2019 Supercon!

The Talks (Part Two of Many)

• 
  

  Shelley Green

  Pressure connections: crimping isn’t as simple as you thought.

  Crimping is generally defined as the joining of two conductors by mechanical forces. At first, the process appears to be rather simple. However, deeper investigations reveal complex dynamics that operate at macroscopic, microscopic, and nanoscales. I will cover the basic theory for pressure connections, examine the role of mechanical properties for both conductivity and tensile strength, look at oxides and surface films, and consider the design challenges for tooling, testing, and validation of crimp quality.

  Mike Harrison

  Everything I’ve Learnt About LEDs.

  LEDs are not all created alike. I will cover a wide range of practical techniques involved in using LEDs, in particular in the context of large-scale installations, hower much of it will be equally applicable to smaller projects. Topics include suitable LED types, drive circuitry, dimming techniques, gamma correction. There will be live demonstrations illustrating many of the areas covered.

  Basic Device Security for Basic Needs

  It feels like every day we hear about an unbelievable new security vulnerability that allows an attacker to spy on your dog through a connected light bulb or program your toaster oven remotely. Some of these are quite elaborate, requiring researchers years to track down. But others are total no-brainers; “why didn’t the manufacturer just do X!”. In our IoT-ified world device security is more important than ever, but not every hardware product needs to be secured like an ATM inside a missile. I will discuss basic design practices and implementation tricks which are easy to incorporate into your product and provide a solid baseline of security against casual adversaries.

  The Future is Us: Why the Open Source And Hobbyist Community Will Drive Hi-Tech Consumer Products

  Where did we the OSHW and hobbyist community come from and what have we accomplished? The truth is we are driving modern consumer electronics industry. From prototyping, to tools to media and training, we have changed it all. I’ll talk about the reasons why, our impact and our future, as well as how to avoid becoming what the older industry is: obsolete.

  Timothy Ansell

  Xilinx Series 7 FPGAs Now Have a Fully Open Source Toolchain!

  You should be super excited about FPGAs and how they allow open source projects to do hardware development. In this talk I will cover a basic introduction into what an FPGA is and can do, what an FPGA toolchain is, and how much things sucked when the only option was to use proprietary toolchains. The SymbiFlow project changed this and I’ll discuss what is currently supported including a demo of Linux on a RISC-V core with a cheap Xilinx FPGA development board.

  Gaining RF Knowledge: An Analog Engineer Dives into RF Circuits

  Starting my engineering career working on low level analog measurement, anything above 1kHz kind of felt like “high frequency”. This is very obviously not the case. I’ll go over the journey of discovering and rediscovering higher frequency techniques and squaring them with the low level measurement basics that I learned at the beginning my career. This will include a discussion of Maxwell’s equations and some of the assumptions that we make when we’re working on different types of circuits. You will find this information useful in the context of RF calculations around cellular, WiFi, Bluetooth and other commonly available communication methods.

  Adventures in Building Secure Networks from Blockchain Transactions

  In our talk, we will show how we designed and built a message authentication system operating on ADANA (Automated Detection of Anomalous Network Activity) and Hyperledger (a “smart contract” form of Blockchain) all hosted on just two servers that were no longer being used by Rowan College at Burlington County. The system was built using Docker, syslog-ng, Hyperledger Fabric and Composer, and a beta version of Splunk. This system is accessible by nodes wired into the network which interact with the hyperledger through a web browser. We’ll present the infrastructure of the network, details of the hyperledger, an explanation of all the tools used by the system, a walkthrough of how the system works, reflections on the particular challenges of this project, and what we see in the future of this technology.

  Replicating a Secure Telephone Key

  The STU-III secure telephone was originally developed by the NSA for defense use in the 1980’s but also saw use in unclassified commercial products like the Motorola Sectel 9600\. However, they require difficult to find electromechanical keys. I will describe the process of creating a compatible key for the Sectel 9600 by reverse engineering the mechanical and electrical design and subsequently fabricating it. Along the way I’ll discuss low volume manufacturing issues and strategies to overcome.

We Want You!

Don’t miss out. One weekend as one of so many amazing people will inspire you and recharge your creative batteries for the coming year of hardware hacking. See you at Supercon!
