3omar.hs is not affiliated with these platforms; projects belong to their creators and are subject to their licences. We only list real, verified project links and remove any project on request.
How the Electronics Projects Hub works
- Pick your board (Arduino, ESP32, Raspberry Pi Pico…) or a category such as home automation or lighting.
- Use the Code, Schematic, PCB and 3D-files filters to show projects that include what you need.
- Press “View on …” to open the original project page, and check its licence before use.
Frequently asked questions
Where do the projects come from?
From public GitHub repositories and community-curated lists, and platforms such as Hackster, Instructables and Hackaday. Every link is verified before it is listed and re-checked on a schedule.
Do you write the projects yourselves?
No. We only list real projects by their creators with the creator and platform shown, and we do not copy their content.
How are board and difficulty decided?
They are derived from the project description and files and reviewed by an admin, so treat them as a guide — report anything wrong.
I want my project removed
Use “Report wrong link” or contact us and we will remove it.
