Koppelting is an annual grassroots festival about peer production and free/libre alternatives for society. It is 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.

21 –  27 August 2017

The weekend of 26 and 27 August will be used for lectures and workshops, in the week before an open hackathon will focus on a number of dedicated projects.


Participation in the hackathon during the week is free. For the weekend, a fee is required, using a decide-yourself pricing model aiming at an average of €50 per person. This will cover basic costs of the location, breakfast, lunch, coffee and tea, video-registration of the talks and travel expenses for some of the speakers. See the costs for details.


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.

Unfortunately, the lecture by Kris de Decker has been cancelled due to unforseen circumstances.

Projects for this year's hackathon include:

  • getting the GCMS of the Biolab to work
  • a hypha CMS programming sprint
  • creating an open video conferencing box
  • creating the food of the future in the foodlab
  • how can the Fablab be used better?
  • creating a board game

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.
