The devroom will take place on Sunday, 1 February 2026 at ULB (Campus Solbosch) [1]. We hope you'll join us for a full day of talks, demos and interesting discussions on designing, modeling and testing hardware using Open Source tools. We welcome any talk proposals about the design and creation of physical objects. Topics of interest include, but are not limited to: - Open Hardware Projects * Open circuits * Product design * The business of open hardware - Circuit Design * Printed circuit board design tools * Circuit simulation - 3d modeling and analysis * Solid modeling tools * Meshing, modeling and transforming physical representations * Finite element analysis - 3d printing * 3d slicing tools * Motor control - Machine design and integration * Open Hardware projects * ECAD/MCAD integration * Thermal analysis * Wire modeling - Physical Model Data storage * Data representation and optimization * Version control in hardware data storage * Collaborative and team-based hardware design techniques Slots will be allocated for short (20 minutes) and long (40 minutes) talks. Speakers need to specify their preferred format. Both include time for questions and answers. Depending on the number of submissions, submitters may be asked to utilize an alternate time format. Important Dates * Submission deadline: 5 December 2025 * Acceptance notifications: 10 December 2025 * Final schedule announcement: 15 December 2025 * Devroom: 1 February 2026 The submission process ---------------------- Please submit your proposal at https://pretalx.fosdem.org/fosdem-2026/cfp before 5 Dec 2025. Select the "Open Hardware and CAD/CAM" session. Please note that the "Open Source Design" track, while a lovely group of wonderful hackers, is not the same. :) Please include the following information with your submission: - Abstract - Preferred Session length - Speaker bio - Link to any hardware / code /slides for the talk Fill in at least a title and abstract for the proposed talk and a suggested duration. Keep in mind that much of the value in these meetings comes from the discussions, so please allot at least 20% of the talk time for questions and answers.
