Teletype Mediated Time Travel

Demo by Russell Senior | @rssenior | During breaks @ Commons

My first real computing experience was mediated through a Teletype Model 33 ASR in high school. The actual computer was miles away, and during lunch a few of us learned by typing into the wonderfully loud clackity-clack-clack contraption, printing on a continuous roll of paper and recording locally on paper punch tape. In the last few decades, I’ve dreamed about recreating this experience. Regrettably, surviving Model 33’s are rare and often expensive and usually broken. Recently, I found @33asr on Twitter and Twitch.tv, a person in the Boston area with a similar formative experience who has reconditioned one and streams shows twice weekly, a constant series of "oh no!" surprise and delight over some mismatch of expectations while trying to fit the anachronism of the Model 33 into a semi-modern computing context. To achieve something similar I am intent on turning a recently purchased IBM Wheelwriter into an interactive teletype. A time machine, able to transcend 40 years.

Bio: A Portland native, Russell was inspired by good science teachers in high school to pursue physics and engineering. In college, he got excited about computers and spent two decades thinking about sciencey questions and helping out with measurement and analysis relating to exposure assessment. Since the mid-aughts, he’s been involved with the Personal Telco Project, a nonprofit that advocates for better telecommunications policy while building open-access, public Wi-Fi networks. In that role, he has worked a lot on embedded Linux, mostly OpenWrt. He sometimes hangs out at DorkbotPDX and occasionally helps out with Futel.

Robot Sumo

Installation by Everyone | Ongoing @ Commons

Are you bad at building robots? Do you enjoy cheap, shoddy technology? Do you like watching lousy robots trying to smash each other? Look no further than Robot Sumo! Robot Sumo is a robot fighting competition for the unmotivated, ungifted, or simply confused, where robots made from whatever’s lying around fight it out in "hand-to-hand" sumo wrestling. Last year, one contestant was made from a stale baguette. This is an opportunity for Teardown participants to embrace their inner under-achiever and resurrect old, broken tech into a genuinely mediocre robot! We had a bunch of rules last year, but no one followed them. This year, the only rule is to come prepared to cheer on your favorites and heckle the competition. Bring your own robot or build one from scratch. May the worst robot win!

Scrap Swap

Installation by Everyone | Ongoing @ Commons

Think of all the spare reels of LEDs, bags of connectors, trays of multiplexers, and boxes of dev boards that lie fallow in your garage/basement/workbench/drawer/shelves/pockets. Multiply that by 250 to get the entire expected inventory of scrap among Teardown attendees. Now, imagine redistributing it all so it gets put to good use. Enter the Scrap Swap room! Bring your scrap! Take someone else’s scrap! We’ll find something to do with anything that’s left over. (Use good judgment - e.g., no toxic waste.)

Cat-herding Development Boards in Debian

Talk by Vagrant Cascadian | @vagrant | Sunday 4:30-5 PM @ Hammer Board Room

Debian supports a growing number of development boards, mostly running one of Debian’s several ARM architectures. More boards are released to the wild every month! Sometimes they go feral, abandoned by their manufacturers and supported by volunteer communities. A few of the more recent ones even act suspiciously like laptops. The challenge is that they are all so similarly different. In order to boot Debian on a new, unique board, changes may be required in several packages, some needing coordination upstream, and some packaging changes may be specific to Debian. I’ll touch on my workflows, communication channels, observation habits, and such, to share ideas on how you too can partake in the fun!

Bio: Vagrant Cascadian maintains a variety of firmware packages in Debian, including u-boot, arm-trusted-firmware and most recently opensbi. In support of reproducible builds, Vagrant maintains a build zoo of over 20 boards constantly rebuilding all of Debian. In the right context, Vagrant enjoys being thrown around even more than tinkering with firmware.

Crowd Supply Q&A + Lightning Talks

Eliminating Fillet Welds in Stainless Steel Block Sculptures

Talk by Dan Good | http://www.dangood.org/ | Sunday 11:30-noon @ Mediatheque

Welding produces very strong metal joints, but that’s not the only consideration when you’re making art. I set out to build the geometric blocky sculptures I was drawing in CAD and spent years figuring out how to make them both beautiful and structurally sound. Here, I’ll go through the design process and show what’s going on on the inside.

Bio: Dan is an artist and engineer who tries to do both together. He has a PhD in electrical engineering and an MFA in electronic music, and it turns out this is what happened.

Everything You Always Wanted to Know About Firmware (But Were Afraid to Ask)

Talk by Stephano Cetola | @stephano | Sunday 4-4:30 PM @ Hammer Board Room

Someone once described microcode as "the computer inside your computer." Today, there are many computers inside your computer, as well as inside modern servers, embedded devices, and quite possibly your toothbrush. Firmware is the code that runs on these tiny machines and allows the hardware to communicate with what most engineers consider software. It is, then, no surprise that firmware has been at the heart of many recent security issues. Presentations and panels about firmware security are now the norm at events like RSA, Hack in the Box, and Defcon. This talk is an introduction to the concept of firmware as embodied by BIOS, UEFI, ARM Trusted Firmware, Coreboot, LinuxBoot, and U-Boot. We will confine ourselves to microprocessor-based systems, covering both ARM and x86, and provide simple examples of how you can start hacking on firmware in your own systems for fun or profit.

Bio: Stephano is an Open Source Program Manager at Intel contributing to TianoCore and CHIPSEC. His main focus is on community engagement and improving the developer experience. In his former lives he was an embedded software engineer, a public health educator, and a cook. In his free time he enjoys exploring the thermal tolerances of electronic circuits, turning FPGAs into intentional radiators, and breaking cyber-physical systems.

Expressive Robots

Talk by Heather Knight | @heatherknight | Saturday 1:30-2:30 PM @ Mediatheque

Performance, acting, and art have unique practices in terms of repeatably conveying character, motivations, and relationships to a human audience that may benefit the development of everyday robots. Entertainment also offers venues for deploying robots and potentially new approaches to constructing knowledge about social robots, and avenues for collecting data from large numbers of people at a time, e.g., in a performance setting or in the wild. This talk will share examples of simple robot expressions from robot furniture to dancing robot jellyfish to robots that tell jokes on stage.

Bio: Heather is an Assistant Professor of Robotics at Oregon State University and directs the CHARISMA Robotics Lab (Collaborative Humans and Robotics: Interaction, Sociability, Machine learning and Art). Their main research contributions are in Human-Robot Interaction and Social Robotics, two fields which seek to optimize the human-robot interface, integrating the fields of engineering, programming, electrical engineering, psychology, and entertainment.

How to Bring Up a New PCB

Talk by Scott Dixon | @scott_dixon | Sunday 10-10:30 AM @ Mediatheque

After a new PCB design has been assembled, it’s time to test and debug it. This is often called "board bringup" and it is something which is seldom explicitly taught. There are a number of things which can be done, both in the initial design stage and during the bring-up process to make it easier to get a new design tested and running.

Bio: I’ve spent the last five years working for a local custom design company doing embedded electronics. Personal interests include electronics and robotics. I also help out at PSU with electronics prototyping and with the OreSat cubesat project.

It’s 8051s All the Way Down

Talk by Adrian Studer | @adistuder | Saturday 3-3:30 PM @ Hammer Board Room

In a typical teardown, we crack open the case, take out the circuit board, follow the traces, and look up the datasheets of all the chips. But what’s going on inside those ICs? And how can we find out? Join me on my journey of reverse engineering the innards of a small ISM radio IC, from the architecture in the datasheet to the disassembled firmware.

Bio: Working on enterprise software by day, Adrian prefers low-level embedded projects at night. When not reverse engineering radio ICs, he uses them to build the dAISy AIS receiver, a popular gadget that tracks ships.

Keeping Customers Happy Through Yield Monitoring and Process Control

Talk by Brad Silvers | @QorvoInc | Friday 4:30-5 PM @ Mediatheque

Few customer issues simply appear. Most leave signals along the way: odd inspection findings at QA, yield loss, new failure modes. In order to detect issues before our customer does, Qorvo employs extensive monitoring to detect these clues real time. We’ll walk through the how and why of yield limits and process monitoring and discuss some real world examples.

Bio: Brad has over 10 years of experience in customer quality roles with both automotive and major cell phone manufacturers. In his current role at Qorvo, he uses his experience in wafer fabrication and back-end processing to catch problems before they get to the customer.

Learning Electronics and Software - The Rainy Way!

Talk by Alvaro Prieto | @alvaroprieto | Friday 4-4:30 PM @ Mediatheque

The best way for me to learn something is by doing it (and making mistakes.) This year, I decided to build a weather station and want to share what I learned along the way. I designed circuit boards and wrote firmware and software in order to make it happen. Designing electronics to go outside was an entirely new endeavor for me. I had to learn about weatherproofing, solar panels, battery management, wireless bootloaders, low-power design, sqlite databases, web frontends for data visualization, and much more! As usual, I made many mistakes along the way and learned many new useful tricks.

Bio: Alvaro is a firmware/hardware engineer that loves making stuff! He gave a talk last year about cheese making.

Long-tail Hardware

Talk by Steve Hodges | https://aka.ms/shodges | Saturday 9-10 AM @ Mediatheque

Recent technologies have made it easier to get certain types of product to market, even for niche products in the so-called ‘long tail.’ Downloadable goods like books, music, movies, and apps are great examples. However, getting a new hardware device to market typically still requires a great deal of expertise. In this talk I will describe why the innovations behind downloadable products are necessary but not sufficient for hardware devices. Based on first-hand experience of device manufacture at scales from hundreds to millions, I will highlight the outstanding challenges faced when transitioning a hardware prototype into a product. I will explain how further technological innovation has the potential to change dynamics in the device market. My aim is to make low-volume manufacture of ‘long-tail hardware’ more accessible, enabling a wider variety of products. Ultimately, I believe this will drive innovation and increase customer choice.

Bio: Steve Hodges is a Principal Researcher at Microsoft where he combines device-related research insights with emerging technologies to create new hardware concepts, tools, and technologies. By seeding adoption of these beyond the lab, he ultimately aims to demonstrate new ways in which technology can empower individuals, organizations, and communities. Examples of his work include Azure Sphere, BBC micro:bit, Sensecam, .NET Gadgeteer, the EPC, and software-defined batteries.

Making USB Accessible: Developing Ultra-low-cost, Open USB Tools

Talk by Kate Temkin & Mikaela Szekely | @ktemkin & @Qyriad | Sunday 1:30-2:30 PM @ Mediatheque

Working with USB designs is often more difficult than it should be. Whether creating USB hardware/software, reverse engineering a USB protocol, or experimenting with USB, engineers and enthusiasts are all too often stymied by the state of USB tooling - existing USB tools are often limited, expensive, and difficult to use. We introduce a new collection of fully-open-source USB hardware and software tools geared towards making USB accessible. We’ll share the techniques we’ve used in developing an ultra-low-cost, open-hardware, high-speed USB analyzer; demonstrate the analysis software we’ve developed, and describe how our software and hardware integrate with the broader open hardware USB community (including projects like OpenVizsla). We also discuss some of the related open software, open gateware, and open hardware projects, including tools developed both by us and by other members of the community. Join us!

Bios: Kate Temkin leads the software development team at Great Scott Gadgets. Kate is a seasoned USB researcher, and maintains a variety of open source hardware and software tools, including FaceDancer and GreatFET, and has discovered a number of well-known USB vulnerabilities, including CVE-2018-6242, which famously allowed full exploitation of the Nintendo Switch.

When not maintaining her own tools, Mikaela contributes to a variety of open source projects, makes truly terrible puns, and hones her computer science skills in scenic Colorado.

Measuring Embedded Machine Learning

Talk by Alasdair Allan | @aallan | Saturday 2:30-3:30 PM @ Mediatheque

While machine learning is traditionally associated with heavy-duty, power-hungry processors, the future of machine learning is on the edge and on small, embedded devices that can run for a year or more on a single coin cell battery. Deep learning can be very energy-efficient, and allows us to makes sense of sensor data. It can turn raw accelerometer data into information about whether a machine is working well or malfunctioning, or recognize voice commands from a microphone feed. The ability to run trained networks "at the edge" nearer the data without the cloud - or even without even a network connection - means that we can interpret sensor data in real-time, pulling signal from the data without storing potentially privacy infringing data in the cloud. This talk shows you how to use machine learning on your own problems, whether you’re using your laptop, a Raspberry Pi, or an ARM Cortex M micro-controller. It looks at the latest hardware intended to speed up machine learning inferencing on the edge, and gives benchmarks as to which platform is fastest.

Bio: Alasdair is a scientist, author, hacker, maker, and journalist. An expert on the Internet of Things and sensor systems, he’s famous for hacking hotel radios, deploying mesh networked sensors through the Moscone Center during Google I/O, and for being behind one of the first big mobile privacy scandals when, back in 2011, he revealed that Apple’s iPhone was tracking user location constantly. He has written eight books, and writes regularly for Hackster.io, Hackaday, and other outlets. A former astronomer, he also built a peer-to-peer autonomous telescope network that detected what was, at the time, the most distant object ever discovered.

Never Mind the Factory: Punk Manufacturing for a Better World

Talk by Rob Ryan-Silva | @DAI_Maker_Lab | Saturday 4-4:30 PM @ Hammer Board Room

There is a lot of talk in hardware circles about the difficult road to manufacturing. But is mass manufacturing always a prerequisite to making an impact with hardware? This talk will explore how punk rock, 3D-printed landmines, queer zines, Cambodian kids’ toys, Soviet cassette trading, and badgelife could point the way to an alternate approach to scale – an approach that could even offer a better life for people in developing countries through hardware.

Bio: Rob Ryan-Silva is an aid worker with almost 25 years of experience in international development. He runs the DAI Maker Lab, where he applies emerging tools and approaches to build hardware and capacities around building hardware in support of foreign aid projects worldwide.

Supercharge Your Hardware (Old and New) with CircuitPython

Talk by Scott Shawcroft | @tannewt | Sunday 10:30-11 AM @ Mediatheque

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 GameBoy with CircuitPython. By the end of the talk, you’ll be able to supercharge your own hardware project with CircuitPython.

Now, CircuitPython ships on thousands of electronics every month, introducing new coders to Python on hardware. Scott’s hobby is bringing CircuitPython to as many devices as possible, including those he finds at thrift stores such as GameBoys and Yamaha Keyboards.

Tiny Blimp! (How to Work on a Project for an Hour at a Time for Two Years)

Talk by Sophi Kravitz | @sophikravitz | Saturday 10:30-11 AM @ Mediatheque

Building a thing that flies is complicated. There are already plenty of challenges in designing something small where the batteries need to last. Adding in communications systems that need to… communicate creates a whole new level of stress. And plopping weight constraints, helium shortages, and aerodynamic controls on top takes toy blimp design to a whole new level. Fun!

Bio: Sophi Kravitz is an art-engineer who has designed control systems for room-sized process equipment, robotics large and small, and crazy art installations, and built props and FX for movies in a past career (if it was a bleeding body part on TV in the 90s, she may have made it). She’s currently working on a project that contains linkages, a quantified-self object, and some blinky because all the things are better with LEDs.
