I’ve been mindful of the BOM in the beginning of the project. But I wasn’t as mindful on the BOM price. And the Formaldehyde sensor was way too expensive.

So after reducing the BOM the project doesn’t have the same complexity. But I think that it could still have the same informational functionality.

So I began striping things down. And in the end I only need one component and that is the SEN 66.

Then I went ahead and made a first draft of the BOM with links from farnel as they were the cheapest. (SPOILER: they were without VAT)

So I have imported the BOM into the readme. After I said a few words about the project and it’s function.

Made a super simple schematic into the readme.

Screenshoted a few images of the CAD assembly exported.

And the I got to the farnel cart and noticed that the prices were without VAT so I went back to laskakit.

And there it was a complete project blueprint.
