Topic :Open Source Hardware at CERN: the first ten years

In 2009, the first version of the Open Hardware Repository ( went live. It was our first step to foster collaboration among scientific laboratories in the domain of hardware development. We then worked on various other fronts, including the drafting of the CERN Open Hardware Licence, working with companies on new business models and joining the KiCad community to develop with them a Free and Open Source PCB design tool which could compete with proprietary alternatives in terms of features and quality. In this talk, I would like to tell you a bit more about this story and focus on two main subjects for the near future: the latest developments on the licensing front, with the imminent publication of CERN OHL v2, and the importance of FOSS tools for PCB design if we are to efficiently share hardware designs.

About the Speaker- Javier is an electronics engineer and a physicist leading the Hardware and Timing section in CERN’s Accelerator Controls Group. He is the initiator of the Open Hardware Repository ( and co-author of the CERN Open Hardware Licence. At CERN, he specialises in timing
systems, and he leads the White Rabbit project, an extension of

Speaker: Junichi Akita

Topic: Impact of NDA-Free & Open Source on LSI Design & Fabrication

Designing LSI chips is one of the most powerful tools to realize idea on hardware. When we start designing LSIs, we need to engage NDA (non-disclosure agreement) with semiconductor manufacturers, since the design rules are their top-secret information. NDA prevents us to make the designed circuits open, thus we can’t share them with other designers. The advances in LSI technologies based on Moore’s Law have achieved not only the advances of LSI functionalities, but also level up of LSIs fabricated by the matured, old-fashioned fabrication technologies. Now, we can use the old-fashioned technologies to meet the certain, advanced area in the hardware requirements. We often don’t need NDA for the old-fashioned technologies, since they are based on well-known technologies. In this talk, the open-source, NDA-free LSI design rule is discussed, as well as our trials on LSI design with open source tools by wide variety of contributors and interests.

About the Speaker: Junichi is currently a professor at Kanazawa University, Japan.

terms of Open Source Hardware.

Speaker: Michael Bretti

Topic: A New and Radical Open Source Initiative Towards the Development of Advanced Electric Propulsion for Space

The author proposes and is currently leading a unique and radically different approach towards electric space propulsion focusing on low-cost, simplified, fully open-source systems. These efforts represent the first and currently only fully open-source, independent, maker-based initiative towards the development and advancement of electric propulsion for small satellites. The goals of these efforts are to open source all types of electric propulsion technologies, as well as testing infrastructure for their development, and provide unprecedented access and resources by showing other enthusiasts how advanced electric propulsion can be designed, developed, and tested using an open source approach on a limited budget with restricted resources and technology at home. With such an open source take on a historically closed field, normally prohibitively costly and advanced technologies can be approached and further developed at the hobbyist level, and provide unique collaborative opportunities to advance the field in a way that cannot be done through normal academic or industry means.

Speaker: Sean Montgomery

Topic: Internal Context, Open Source Hardware and Democratizing the Future of Augmented Cognition

Electrical and chemical signals are constantly traveling throughout our brains and bodies, carrying sensations, thoughts, emotions and our reactions to the world around us. Studying these signals and how they are altered by external stimuli and internal contexts gives us a window into ourselves and how we can enhance our health, well-being and capabilities in the 21st century. My lab has been working for the past 2 years on a wearable open-source sensor for capturing emotional, physiological, and movement data. I’ll discuss how a low-cost sensor can help democratize Brain-Computer Interface (BCI) research, create more dialog between artistic and scientific inquiry, bring BCI research into classrooms at a younger age and create a multiplier toward understanding human cognition. I’ll also discuss the value of having open source tools for scientific research and creating a future in which our internal context combined with artificial intelligence play a central role in augmenting human cognition.

Speaker: Amanda Wozniak

Topic: All Good Things Scale

This talk is about how All Good Things Scale (TM). There are a very specific set of things needed in the recipe to engineer at scale which are required to build unstoppable momentum. This talk will cover the (sometimes small) things I see happening in Open Source Hardware that will only help the movement and its contributors do more, bigger, and greater things. I will list what I’d love to see more of! This talk is based on my career experience growing engineering teams and doing product development in my previous roles, my stint as a works-for-beer hacker project consultant in the Open Hardware space, and my love of all things NASA, IBM, and Bell Laboratories.  

About the speaker: Amanda (w0z) Wozniak is a Boston-based electrical engineer who’s notable achievements include: hardware designer for the DEFCON 17 and 18 Ninja Badges (#BadgeLife), three time speaker at the OHS, and most-featured guest on Adafruit’s “Ask An Engineer.” She is currently a Principal Systems Engineer at Amazon Robotics, and this talk is completely unrelated to robotics, logistics, the cloud, or anything else in the domain of her current employer. 

Speaker: Patrícia Alves Oliveira

Topic: YOLO, a social robot for creativity

YOLO is a robot that was designed, developed, and fabricated to develop creativity during play. It is meant to be used by children as a character during storytelling, provoking new storylines that would not emerge otherwise. During this talk, we will detail the design process and fabrication of YOLO. Experimental studies with this robot showed YOLO is a tool that serves to increase original ideas during the creative process of storytelling. YOLO is an open-source robot, enabling researchers and communities to enjoy the fabrication of a robot that can increase creative thinking.

Speaker: Robert Ryan- Silva

Topic: How Hardware Learns: Five Years in the Life of an Open Source Flood Warning Design

The DAI Maker Lab builds hardware and capacities to build hardware in support of foreign aid projects in the developing world. Their most widely adopted design is an open source flood early warning device best known by the Cambodian name Tepmachcha. Like many hardware designs that are not locked in by mass manufacturing, Tepmachcha has changed over time as deployment reveals flaws and contributors make improvements. Unlike many designs, it has had to adapt to idiosyncratic operating environments in Honduras, Cambodia, Indonesia, and Nepal. These adjustments will be both familiar and strange to the OSH community, and reflect learnings about the process and need for hyperlocal design in all manner of contexts.

About the Speaker: Rob Ryan-Silva is an aid worker with more than 25 years of experience implementing capacity building projects in developing countries. He is currently the Director of the DAI Maker Lab, which uses emerging tools and approaches to build hardware and capacities to build hardware in support of international development projects. 

Speaker: Lorena Ramírez-López

Topic: I’m giving it all she’s got: Troubleshooting with obsolete hardware in archives and museums

As archivists and conservators, we are always trying to make do with what we have available; we adhere to and aim for the highest attainable levels of the National Digital Stewardship Alliance and best digital preservation standards in the face of limited financial, staff, and equipment resources. The workflows and digitization stations we develop are curated to media formats, including analog media such as u-matic, VHS, and DAT. We have been able to develop open source software to help with the digitization and migration process of these formats, but we are facing the problem that these playback decks have become obsolete. Even the contemporary hardware of our workflows have been discontinued. This talk presents a general list of the types of equipment we require in our work and how we troubleshoot issues of obsolescence.

Topic: Violet: Introducing the world’s first open source hardware Direct Air Carbon Capture (DACC) machine

The the most recent integrated assessment models (IAMs) informing the U.N. Intergovernmental Panel on Climate Change’s (IPCC) current forecasts and policy recommendations make clear that carbon dioxide removal (CDR) on the order of hundreds of billions of tons by the end of the century will be necessary to limit global warming to 1.5 C in that time frame. As recognition of this fact has become more pervasive Direct Air Capture (DAC), a sorbent-based technology that chemically absorbs CO2 from the ambient air, has gained greater attention as a promising CDR application.
However, significant cost, energy conversion and performance barriers must be overcome if DAC is to play an important role in achieving necessary rates of carbon removal. This discussion will focus on a new effort underway to accelerate technical innovation and breakthroughs in the DAC domain through an open source hardware approach. The presenters will describe the motivations behind and status of an ongoing collaboration between NYU faculty, grassroots DAC advocates and an engineering team at the University of Zhejiang in China to open license and certify a miniaturized DAC machine with the goal of facilitating voluntary global collaborative R&D projects focused on solving leading problems limiting DAC’s advancement and deployment. A prototype of the miniatured unit to be licensed will be presented.
