Today, a grad from our school came and demo’ed a remote-controlled helicopter. She’s in third year Computer Engineering (not Computer Science) right now, and this was her project for the past three months. It’s SO AWESOME.

They built everything. Within their little group, they had board and circuit builders, physical helicopter makers, and programmers. There were four fans sticking out of a little box in the middle, pointing in the four outside directions, facing downwards. They are controlled by a central processor, which they built themselves. That thing measures angular velocities of the fans and increases/decreases speed to create a balance.

No pictures =( my camera was at home. I’ll friggin build one of these some day.
