Technically, you are violating copyright, unless you actively sought and received permission to use these images.



Ideally, it is expected that members post projects that they have actually made themselves, using images they have created themselves.



Sometimes original images are not possible or appropriate, but in this case they are.



I recommend you follow these instructions yourself, taking photos as you go, and then replacing the copied images with your own versions, and your own description of the Make (which would include different approaches you took to the plan), along with a link back to the inspiring original.



That would then become a genuinely awesome first project, rather than a somewhat disappointing copy.
