Gravity Eurorack clock module open source fuels modular innovation

Gravity Eurorack clock module open source refers to the Gravity clock module, which is open-source hardware developed by Kyiv-based Sitka Instruments. The module is Arduino-based, and the author describes Gravity as his favorite clock module and says it is easy to hack on. Design files and firmware are hosted on a self-hosted Gitea platform maintained by the project. There are external resources and links to Gravity firmware repositories and an alt-gravity page.

The hardware is licensed under CERN-OHL-S, which has been described as “strongly reciprocal,” and the software is licensed under GPLv3. Alternate firmwares available for the module include ALT-GRAVITY, Euclidean, and Comprator. A library called libGravity exists to support Gravity firmware. These published hardware designs, firmware options, and supporting libraries make up the project components that have been released by the developer.

The Gravity Eurorack clock module, developed by Sitka Instruments, is an open-source hardware project. The module is built on an Arduino platform, allowing for flexibility and customization. Its hardware is licensed under the CERN Open Hardware License Strongly Reciprocal (CERN-OHL-S), which provides a “strongly reciprocal” framework, meaning that any derivative work must retain the same licensing terms, similar to copyleft principles.

For software, the Gravity module employs the GPLv3 license, ensuring that users have the freedom to use, study, modify, and distribute the software freely. This enables developers to innovate and build upon the existing software foundation. The availability of alternate firmwares such as ALT-GRAVITY, Euclidean, and Comprator enhances the module’s functionality by offering users different options to tailor the module to their specific needs.

Additionally, a dedicated library known as libGravity supports the firmware, making it easier for developers to work with the clock module. All code, along with the necessary hardware design files, is hosted on a self-hosted Gitea platform, facilitating collaboration and open-source development.

The Gravity project publishes several software resources that support development and firmware deployment for the module. A library called libGravity is provided to support Gravity firmware development and integration with module code. Multiple firmware repositories are available, and the project includes an alt-gravity page that links to alternative firmware implementations. The published repositories and library are presented as distinct software components maintained for the Gravity ecosystem.

Alternate firmware projects distributed for the module include ALT-GRAVITY, Euclidean, and Comprator. These alternate firmwares are listed alongside the main Gravity firmware in the project’s collection of software resources. Gravity is Arduino-based, and the available firmware repositories target that platform for firmware implementation. The combination of the libGravity library and the available firmware repositories constitutes the core software resources provided by the project.

All code and hardware design files for the project are hosted on a self-hosted Gitea platform. External resources and links to the firmware repositories and the alt-gravity page are made available through that hosting arrangement. The hosted repositories contain the firmware projects and supporting libraries referenced above. The hosting and published repositories together form the accessible software resource base for the Gravity project.

Kyiv-based Sitka Instruments is the creator of the Gravity Eurorack clock module. The project’s developer is Oleksiy Hrachov. The article’s author describes Gravity as his favorite clock module and says it is easy to hack on. Sitka has published the module’s hardware designs and firmware as part of the project’s release.

Published software components include the main Gravity firmware and supporting repositories such as libGravity, and the project lists alternate firmware options. Alternate firmware projects named for the module include ALT-GRAVITY, Euclidean, and Comprator. The project’s code and hardware design files are hosted on a self-hosted Gitea platform. External resources and links to the firmware repositories and the alt-gravity page are provided alongside the hosted repositories. The published libraries and firmware repositories constitute the project’s public software assets.

The article explicitly mentions external resources and links related to the Gravity Eurorack clock module, including links to Gravity firmware repositories and an alt-gravity page. The article indicates that these resources and links are available alongside the hosted project repositories.

No explicit external URLs for the firmware repositories, the alt-gravity page, or other linked resources are present in the available source material. The available sources do not provide this information.

CONCLUSION

As published, the Gravity Eurorack clock module open source project by Kyiv-based Sitka Instruments comprises published hardware designs, firmware, supporting libraries, and hosted repositories that together make the project’s resources accessible to others. The project’s dual licensing—hardware under CERN-OHL-S and software under GPLv3—remains in place and governs reuse of the published materials.

The project’s Arduino-based architecture, the availability of libGravity and alternative firmwares such as ALT-GRAVITY, Euclidean and Comprator, and the hosting on a self-hosted Gitea platform are part of the publicly released materials. These published elements collectively define the project’s open-source character and licensing framework. Together, these publicly released assets are available under the stated licensing terms.
