Open Source Licenses
The Void Grows is open-source hardware and software. Build it, modify it, sell it. Here are the details.
DUAL LICENSE
Two Licenses, One Project
Hardware designs use CERN-OHL-P-2.0 (the gold standard for open hardware). All code uses MIT. Both are maximally permissive.
Hardware Designs
CERN-OHL-P-2.0
You can use, study, modify, and distribute the hardware designs freely. You may use them commercially. Attribution to the original project is appreciated but not legally required for the permissive variant.
Covers: STL files, OpenSCAD source, BOM, assembly guide, wiring diagrams
You can: Use commercially, modify, distribute, private use
You must: Include license text if redistributing source
Firmware
MIT
Permission is granted, free of charge, to any person obtaining a copy to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies. Attribution required in copies.
Covers: ESP32 Arduino code, PlatformIO configuration
You can: Use commercially, modify, distribute, sublicense
You must: Include copyright notice and license in copies
Web App
MIT
Same terms as firmware. The Void Core companion app is fully open source under MIT.
Covers: This website, companion app, documentation site code
You can: Use commercially, modify, distribute, sublicense
You must: Include copyright notice and license in copies
COMMON QUESTIONS
License FAQ
Can I sell domes I build from these designs?
Yes. Both CERN-OHL-P-2.0 and MIT are permissive licenses. You can manufacture and sell products based on these designs commercially with no royalties or fees.
Do I need to open-source my modifications?
No. The permissive variant of CERN-OHL-P-2.0 does not require you to share modifications. If you redistribute the original source files, include the license text.
Can I use the firmware in a different product?
Yes. The MIT license allows you to use, copy, modify, and sublicense the firmware code for any purpose, including proprietary products. Include the copyright notice.
What about the brand name and logo?
The licenses cover the technical designs and code only. The Void Grows name and brand assets are trademarks and are not covered by these open-source licenses.
Where do I find the actual license files?
Each repository root contains a LICENSE file. Hardware designs include CERN-OHL-P-2.0 in the /hardware directory. Firmware and app directories contain MIT license files.
