Hi,

Have you browsed the “Mechanical Engineering Project Ideas” listed at this link:

https://www.sciencebuddies.org/science- ... ngineering

Quite a few mechanical projects are listed there. Perhaps you can find one that fits with your interests or one that will inspire another project idea.

I hope this helps. Please ask again if you have more questions.
