Build you own project section

[Willaiem]

This issue will contain the materials, which will be added to the existing Build you own project section.

What to do:

• split the section into two sub-sections - one with project ideas and second with "how to make project" materials

I've put up a pull request to add @Willaiem! :tada:

We already have split docs for project ideas and complete project tutorials

Upcoming update with better document titles is going to help differentiate them.

To do: Move materials between these two sections to match the title of the document
