I got my idea inspired by the padlet that was on dx at first. At first, I put some of the designs on the padlet together that made my “smelling machine” For example, one of the ideas was a temperature gun.  And then I saw a couple of other objects inspired mine. For my “smelling machine” it has a small door at the back of it to change the web inside so the next time you text other smells, the smell you tested before will not get mixed up together. There are also buttons on the front, you can start it, stop it, or restart. And when you want to start testing, yo press the very top button. Then the smell will go into the web and the little touch screen at the back will show you what smell it is so you can see. there is also a place where you can hold at the bottom.
