This workshop explores the design and construction of hardware and firmware related to 3D printers, including a briefing on the capabilities of the open source, Crowd Supply-funded JuicyBoard and Juicyware used for 3D printers, CNC machines, laser cutters, and much more.
This workshop explores the creative possibilities of production automation. Part design is only the first step in production, after which you have to figure out how to get the geometries you want, how to minimize material waste, how to program machines, and how to manage the parts as they are produced. Bottlenecks for low-volume production are vastly different than their industrial counterparts. What are the tensions between design and production at the makerspace scale?
In this workshop we will run a pop-up production line to explore the different roles and tools in low-volume production. We’ll make a site-specific installation using custom design tools, custom machines made with the Cardboard Machine Kit, and explore automated ways in which we can let time and budget inform our production.
OpticSpy is an open source hardware module for experimenting with optical data transmissions. It captures, amplifies, and converts an optical signal from a visible or infrared light source into a digital form that can be analyzed or decoded with a computer. Tomu is a programmable computer that fits inside a USB port and contains two on-board LEDs.
In this workshop, Joe Grand, creator of the OpticSpy, and Sean Cross, of Tomu fame, guide you through the process of creating a system to transfer secret messages in a way that the human eye cannot detect. Attendees must provide their own laptop. OpticSpy and Tomu units will be provided.

We’ll touch on how to manufacture your boards at home, and best practices for sending them off to be manufactured.
Learn about this RISC-V thing you have been hearing so much about and how to get started hacking on real RISC-V hardware. The presenters, Drew Barbier and Meadhbh Hamrick, represent the entirety of the SiFive Applications Engineering department.
The first Google AIY Project kit was made available for free on the cover of the official Raspberry Pi magazine, the MagPi. It proved to be so popular that the magazine sold out in a matter of hours. The kits bring Google’s machine learning algorithms to developers that have limited experience in the field, to allow them to prototype machine learning applications and smart hardware more easily.
The original Voice Kit allowed you to prototype basic, but still useful, voice interfaces for machine learning applications on the Raspberry Pi. While the newer Vision Kit allows you to build object, face, and emotion recognition projects with the Raspberry Pi Zero. We walk through how to setup and build the kits, how to use both the kits’ Python SDK to use machine learning in the cloud, and investigate how to run applications at the edge, on the Raspberry Pi itself, without needing a network connection.
Electron microscopes are really cool. Having one in your own shop is even cooler. Getting it to your shop without breaking it? That’s where the real challenge is. I have facilitated the acquisition, mobilization, and transport of a few of these instruments and every time I learn about some new trick, something else to look out for, or some better way of moving large, sensitive pieces of equipment. My goal in this session is to teach you many of these tips and tricks as I can. This includes a lot of lessons specific to SEM/TEM, like how to break vacuum on a system that doesn’t have power or air pressure to actuate valves, and more generalized information like how to work with transport companies, the different tools that are available for moving heavy pieces of equipment, and what to do when they send a 53’ truck with an extended cab for delivery in a residential area.
Git, Bitbucket, Subversion, and other tools have made source control management (SCM) a no-brainer for software projects no matter how big or small. What about hardware? Product Lifecycle Management (PLM) is often considered an “enterprise” pursuit. I think it’s time to change this perception.
Designing a circuit board and having it manufactured have never been easier thanks to open source KiCad software and OSH Park. We will walk through laying out a very simple LED circuit and submitting it for manufacture.
Hebocon is a robot fighting competition “for the technically ungifted” where high-tech robots are banned.

This workshop is a series of exercises that will give you a basic understanding of what FPGAs are, how they work, and how to program them in Verilog. You will flash LEDs, display salutations, use switches and buttons as input, do some type conversion, and then implement a simple calculator.
All hardware and software is provided for use during the workshop. Understanding of basic binary operations (AND, OR, NOT) is essential background.
There will be two sessions, each limited to 30 participants.
This talk will cover the development of the Thotcon 0x9 badge and explore various challenges, opportunities, and design considerations faced when creating a game experience for custom-built, embedded, interconnected systems. It will explore these topics through the use of the Thotcon 0x9 and 0x8 game badges as case studies in hardware and software development, as well as human-computer interaction and game design. We’ll touch on the design of these systems, and highlight material differences between both software design, and the design of physical artifacts. We’ll also talk about making games!
Open source electronics are an amazing thing. Let’s cultivate that by doing it right. Just publishing your CAD files isn’t going to cut it: let’s actually go through all the files you need to have a successful open source project that doesn’t make your users hate you. We’ll discuss readmes, short-but-kickass requirements documentation, schematics, board layouts, bill of materials, and ideas for documenting the project’s outcome and current state.
Part public service and part public art, Futel is keeping the payphone alive by installing them in public locations and offering free calls and interactive audio experiences. Why do we do it? Is it sustainable?
Now that we are finally living in the cyberpunk dystopia promised in the 80s, we are poised to seize this moment. What aspects of the project make it effective, and how can we apply them to other creative technological projects? Which constraints give us the freedom to use our abilities to effect change, or at least confuse people and delay boredom?
Traditionally, product development and intellectual property have been thought of as inextricably bound together. The rise of open source hardware over the past decade has challenged these ideas by creating new markets that thrive on standards of sharing and transparency. Even if your upcoming product cannot be open source, there is still enormous value to be gained and given back to the community. This talk highlights specific use cases where OSH played a pivotal role in bringing to market a series of embedded devices, shows how OSH can be leveraged to quickly get prototypes and demos in the hands of potential customers, and discusses the role of open source hardware in educating a new generation of embedded developers.
Involving your product’s manufacturer early in the design phase will save you time and money in the long run. Maybe your product is just an idea. Maybe you have started your product design. Maybe you even have a prototype. But is your product ready for manufacturing? This session will show you how partnering with your electronics design and contract manufacturer early in the design phase will avoid costly delays.

Python is generally considered a high-level language a long way from hardware, which actually makes it an awesome tool for helping with the design and creation of hardware! Python was essential in developing the HDMI2USB.tv open source firmware and hardware for video capture. The system has been in use since late 2015 and used at numerous conferences such as Linux.conf.au, DebConf, and various PyCon conferences around the world. This talk will cover Python hardware description languages (HDLs) for creating “gateware” for FPGA chips or even real IC design; Python tools for deploying, programming and debugging embedded systems; and Python scripting for hardware schematic layout and design rule checking.
While most PCBs can be simple rectangles, sometimes the design requires more complex geometry. EDA tools don’t always make this simple, so we will go over a few KiCad tips to make it easier. In this talk you will learn how to import unique board shapes from Fusion 360, create arbitrary fill zones using images, and embed high-frequency RF filters. We will use multiple software packages to enhance KiCad’s performance beyond its obvious use.

The process of designing, implementing, publishing, supporting, and using a hardware project is complicated enough without having to worry about security. Whether you’re publishing a software library to interface with your hardware device, or worried someone’s going to reprogram your art installation, I’ll go over a few security-related points to consider at each step of a product or project’s lifecycle. I’ll share a few examples of hardware security issues I’ve encountered, and simple solutions that have helped. I’ll wrap up with a checklist of things to keep in mind for your current and future projects. Hopefully you’ll come away knowing how to make some minor improvements to your projects that will go a long way towards making them more secure.
In this presentation-demo hybrid, we will cover basic troubleshooting and safe suggestions for the DIY data recovery enthusiast. The focus will be on Seagate branded drives, though we will also briefly discuss what makes the Seagate HDD simpler to fix than Western Digital when using these specific methods. In addition to hardware repair techniques, we will also present a live demonstration of a few different software solutions for specific issues with Seagate external drives. We will touch on certain criteria that must be met in order for a successful recovery to take place outside of a professional data recovery lab. The talk is targeted at those with fundamental awareness to beginner level understanding, though we are happy to indulge experts, too.
In today’s world of digital everything, what does it mean to be hardware? Are devices these days simply an assembly of nuts, bolts, wires, fiberglass, and doped silicon, or is there more to it? Once we apply power, things tend to get more complicated. Firmware is an often misunderstood aspect of hardware development. It gets lumped into the software category, but can easily take on a life of its own. Written on microcontrollers (MCUs) and system on chips (SoCs), firmware allows everything from the blinking of LEDs to full fledged operating systems. However simple or complex, well-crafted firmware is the bridge between the physical hardware and the intended application.
OpticSpy is an open source hardware module for experimenting with optical data transmissions. It captures, amplifies, and converts an optical signal from a visible or infrared light source into a digital form that can be analyzed or decoded with a computer. With OpticSpy, electronics hobbyists and hardware hackers can search for covert channels, which intentionally exfiltrate data in a way undetectable to the human eye, add data transfer functionality to a project, or explore signals from remote controls and other systems that send information through light waves. Crowd Supply hosted a successful campaign for OpticSpy in March. This talk explores the history of optical communications, discusses details of OpticSpy’s operation and calibration, and gives some demonstrations of the unit in action.
Did you ever want to be immortalized in the medium you use everyday? Maybe can’t live without a two-layer circuit board of your pet on your desk? In this workshop we will take a picture of your choice and turn it into a manufacturable PCB design. You will be guided through the process from image file to gerber files using open source software. This workshop will require a laptop with Inkscape and KiCad pre-installed, as well a pre-selected image.
The accessibility of open source hardware is predicated on reliable low-volume component sourcing. How can you best design a Bill of Materials (BOM) for a toolkit or infrastructural hardware contribution? Reproducibility of parts and assemblies is key! How do you make it easy for others to build on your designs? Drawing from experiences in designing open source hardware machine building kits, I give recommendations for reproducible design BOMs.
Too often, we assume our first design will be perfect when designing custom PCBs for our projects. Unfortunately, this assumption often leads to a frustrating experience while debugging the board, and may lead to a series of board revisions before the board is usable. Learn design, documentation, and layout techniques to make your hardware designs easier to debug and quicker to rework, and increase your chances of the first version working and the second version being perfect.
MIDI is an established protocol from 1983 that helps musical instruments speak to one another. With the introduction of WebMIDI to Chrome, the mature package ecosystem available to Node, and the prevalence and affordability of single-board microcontrollers like Arduino, Espruino, and others, it’s easier than ever to build and interact with custom hardware directly in the browser! In this talk, I’ll cover how MIDI is suddenly relevant again and can be used for many creative applications beyond music. I’ll give an overview of the technologies and introduce you to interactive demos using commercially-available and home-brewed MIDI controllers.
My goal was to get better at circuit design, board layout, and software, so I decided to take on a new project: cheesemaking! In order to make Brie, I needed a temperature and humidity controlled fridge. In developing the necessary circuits, I ran into many problems and learned about many topics, such as using solder paste and stencils, having a board manufactured by a third party, dealing with strange USB issues, making cheese-shaped circuit boards, making cheese-shaped cheese, capturing and plotting data with Python, adding proper load capacitors to crystal oscillators, and many more.
Healthcare and fitness devices do not always have to be black boxes concealing what is going. In this talk, I’ll describe our journey of developing crowdfunded, open source medical devices, looking also at the future of these devices. I will also talk about how open sourcing these devices has opened up a whole new world of possibilities.
This workshop will take newcomers and professionals alike through the process of designing professional, production-grade hardware using Autodesk EAGLE. And though we’ll be learning how to get the most from EAGLE, this hands-on workshop will go beyond the tools to examine the processes used by professionals designing products at scale. Issues of design methodology, circuit technique, PCB layout technique, industry standards, libraries and reuse, data management, interoperability between the eCAD and mCAD domains, and more will all be discussed as we build a real design from start to finish.

We’ll blink some addressable LEDs, connect to a network, and display data on a tiny OLED display, all of which you can take home and continue building on. Limited to 15 participants.
Signet is a free and open source and open hardware portable USB device that stores passwords and a variety of other personal information in an encrypted memory, and can enter them into applications by acting as a USB keyboard. In this workshop, you’ll be set up to develop on a Signet device and guided through the process of making changes and improvements.
Designing circuits and laying out a printed circuit board (PCB) can be complicated and time-intensive. It also happens to be a very expensive process as well, which is why there are many shortcuts and tricks that design engineers use to cut down cost and time of development. Being aware of these shortcuts and tricks can also save time when reverse engineering hardware. Implementing security and countermeasures on PCBs is often the last priority for design engineers. I will point out how understanding the hardware design engineering process can directly lead to finding vulnerabilities in hardware.
