Applications for the OHM cohort starting on October 2022 are now OPEN, learn more in this blog post.


Apply now to the cohort starting on October 2022, deadline: September 2nd

Dear Open Source Hardware community, friends, enthusiasts and allies: We are very happy to announce that Open Hardware Makers (OHM) is ready to open its second 2022 cohort!

Sponsored by Code for Science & Society, this cohort is entirely dedicated to Open Science Hardware!!

What is OHM in a nutshell

OHM is an online mentorship program for open source hardware projects and their developers. Selected applicants learn the best practices for building reusable, inclusive and sustainable open projects, supported by 1-to-1 mentorship and a vibrant community of experts and peers.

How does OHM work?

Open Hardware Makers is organized in 16-weeks cohorts; during this time participants go through 8 hands-on modules, each taking 2 weeks to complete. The complete Open Hardware Makers Curriculum can be found here.

OHM Outline

Selected applicants are matched with a mentor, interact with each other in “cohort calls”, and their projects are assessed by a group of experts who provide feedback and opportunities for improvement. They are also expected to present a demo of their projects by the end of the program, and participate in a global sprint in preparation for the demo. Learn more about how the program works and time commitmments in our website.

Why apply to OHM?

Building open hardware projects is exciting, but making them reusable, inclusive and sustainable takes quite some effort. There are lots of resources online for learning how to build stuff, but how do you ensure your project is making a contribution to the community? How do you design your project so others can find it, contribute to it, and make it grow?

Open Hardware Makers is designed to address this gap. We connect you with a global community of mentors who will guide you through this process, experts who will assess your opportunities for improvement, and peers to share your learnings along the way. Our curriculum was put together based on a wide consultation with members of the Open Source Hardware community, to ensure we are reflecting the best practices from work in real life.

Who can apply?

Applicants are already running or starting an open hardware project. Successful applicants are willing to design and develop open hardware projects that empower others to collaborate within inclusive communities. They are passionate about openness and are ready to learn and apply open hardware best practices to their projects while supporting the global open hardware movement.

To apply to OHM therefore you need to:

  • - be involved in the core team of a hardware project,
  • - provide a link to publicly available documentation (doesn't have to be perfect), or
  • - provide a “one pager” with the project plan, including bill of materials and their availability,
  • - be willing to apply open hardware, software and content licenses to your project by the end of the program.
  • - for this cohort, projects should be related to science, that is the hardware being developed needs to be used for scienctific purposes.


We welcome applications from all around the world, at different stages of project development, individually or in teams.
