Upcoming conference: Meetkoppel: 28 & 29 January 2023

The past years have seen many community science initiatives starting to gather data about their local environments. Large amounts of data are stored on servers around the world. It is one thing however to count, observe or measure and to develop the technology for doing so. Another thing is to use the data. Meetkoppel addresses the following topics: How do we validate and compare measurements across initiatives and sensor gear? How do they translate into meaningful insights to be used for action in policy making or personal lives?

Note: When no talk is ongoing, the livestream page will show "The media could not be loaded", just refresh around the time the talk starts (and maybe retry a little later, since we're not always 100% on time).

What? During two days we bring together makers, thinkers and users of Community Science projects to exchange ideas and plans.

Why? There are many online platforms on which people can share their knowledge, but there is nothing better and more inspiring than meeting face to face and cooperating on the spot.

Who? When you are working on projects that involve developing and/or using sensors and work on the data, we think that this weekend will help you find others that are working on this. You can exchange plans and ideas and start new co-operations. And you will have fun hearing and interacting about projects you may never have heard of before.

When? Saturday and Sunday, january 28 and 29, 2023, approximately 10:00 to 17:00.

Where? Meetkoppel will be held at De WAR, Heiligenbergerweg 34 in Amersfoort, The Netherlands. We will use open source software on a self hosted server to ensure a smooth experience with no privacy infringement.

How much? For participation a fee is required, using a decide-yourself pricing model. For this online edition our costs are much lower than normal, but any surplus proceeds will be put to good use (e.g. for maintainance and further development of the community tools supporting the Koppelting communmity), so we encourage you to pick a fee that's appropriate for the value that you will receive from attending this conference. See the costs page for details.

How do I join this? Visit the lineup, see what you want to share with the group, find you niche and come tell us what you have to tell! If you want to contribute something to the linup, first sign up as a participant, then you will get an e-mail with a link to add your contribution.

How long? The detailed timetable will be made available shortly before the event, but we expect to work with one-hour slots for each programme entry. For presentations, this could be up to 30 minutes of presentation, 15 minutes for questions and 15 minutes break. If you need more or less time for your contribution, or have other specific ideas, let us know in the notes field of your contribution.

Koppelting is an annual grassroots festival about peer production and free/libre alternatives for society. Sometimes, a special theme is chosen, like for Meetkoppel. Koppelting is always filled with projects, lectures, debates and workshops, and is co-created by the attendees. Anyone can contribute, whether by giving a lecture, a workshop or demonstration, or by simply participating, helping out and engaging in good discussion.


Koppelting is held at De WAR in Amersfoort, the Netherlands, home to the world's first 100% open source fablab and the experimental Cooperative University of Amersfoort.


If you would like to present something, have an idea for a hackaton project, suggest someone else for a presentation, or otherwise want to contribute, we are happy to hear about his. Registration for the festival and submission of presentations can be done on the sign-up page.

You can see the contributions to the programme on the line-up page.

Koppelting is a continuation of the FabFuse unconferences that took place from 2012 to 2015. During these years the scope widened from fablab-oriented topics to grassroots organisation, open knowledge and peer production.
