Builder Crash Course - December 2025

Update

Friends,

After the flurry of interest spawned by our recent viral video, the dust is settling. We have updated the website -

https://www.opensourceecology.org/builder_crash_course_2025-2/

Please review the update. The dates should now be correct, and registration form is updated. Early Bird cutoff is October 20, 2025.

Please read the logistics section thoroughly - https://wiki.opensourceecology.org/wiki/Future_Builders_Crash_Course_Logistics

See the section on pre-event preparation, work exchange, and how you can get the most out of the onsite time.

Note that we are waiving the HabLab hostel accommodations fee for work exchange participants - but retaining the food costs for the duration of the workshop. This should clarify any confusion from the older announcement - and please let me know if you have any questions. Then reigister and begin preparing by downloading our CAD file so you get the most out of the workshop. The more people download the file, the more transparent the build will be.

So now is the time to fill out our Workshop Logistics Form to coordinate, so please do that after you register and pay - for each person as that's where we send all info and communications:
