Build Application: Yap7

[Yap7]

Update : After seeing the trial and getting a bigger picture I would suggest sending Yap7 to school....

That or I build something so advanced that nobody understand it. I learned some "redstone vocabulary" after my failure so now I think I can explain this system better.

But like I said, the trial is really hard for me. You test knowledge and not skill, so for me which don't know any component's name, I haven't any way to pass the trial, even if I build something more advanced than an ALU.
