An open science lab in your pocket

An open source hardware add-on to Android or iPhone that allows the user to connect to potentially hundreds of available sensors. 


Air quality sensors by ordinary citizens

Concerned citizens being invited into the development of electronic sensors and building a community around better air quality.

Show Me the Money

Throughout five podcast episodes, we talk to open-source frontrunners, thought leaders, and experts about the business of going open.

This podcast is produced by DDC – Danish Design Center

#01 Where’s the Money in Open-Source Hardware?

The hosts introduce the Revenue Model Catalog – an open-source collection of strategic approaches and best practice examples from businesses making money by giving away their blueprint for free.

#02 The Return of the Commons – Can Open-Source Democratize Product Design?

Paul Stacey, former Associate Director of Global Learning for Creative Commons, shares some essential knowledge, insights, and inspirations about the origins of the commons, the path to where we are today, and how open-source is changing the future of product design.

#03 And Then There was RepRap – How an Open-Source Project Gave Birth to an Industry

In this episode, open-source royalty and the main protagonist behind RepRap, Adrian Bowyer, share his experiences from the RepRap project and help us reflect on the episodes-old question; going open vs. staying closed.

#04 Sharing a Little or a Lot – How Do You Decide What and How to Open Up?

We sit down with Martin Häuer of Open Source Ecology Germany to understand which options are available for businesses when navigating beyond the trenches of the closed-source economy.

#05 Building a Jurassic Park – When Patents Go Extinct, What’s the Alternative?

In this episode, we ask Jaime Arredondo to uncover the thoughts and principles behind his perhaps most bold idea to date: The Open Patent.

Open Hardware Future Talk Pt.1

Why is Open Source  such a promising alternative to traditional product creation? 

Open Hardware
Future Talks

During the pandemic, we gathered project partners and open-source enthusiasts online to discuss the benefits, possibilities and challenges of open-source hardware production.
