Eagle projects are supposed to be something that improves the community and involves your entire troop. This sounds like a fourth-grade art fair project.
The project should improve the community and demonstrate leadership skills over your peers - which doesn't simply include Scouts. Involving only Scouts is actually the easy way out.
When you find a Scout who's able to involve friends from school, church, and the neighborhood, as well as other Scouts . . . that's impressive.
Eagle projects do not have to involve the entire Troop. They don’t have to involve anyone from the Troop, although it is certainly customary. They do have to involve enough other people that the Eagle candidate has to demonstrate leadership of those people, as opposed to doing all or the majority of the work himself.
