•3 1x1 bricks with stud on side
•6 1x1 round plates
•4 1x2 tiles (vents)

•A 1x1x9 antenna
•A 2x2 dish
•A 1x1 brick with studs on all sides
•A tube
•A lever
•A 1x1 thingy that hangs over brick...

Step 2: Step1:

Place a 1x1 round plate and the dish on top. And then the 1x1 brick with studs on all sides.Then a round brick and a plate. Repeat until you have 3 round bricks left and no round plates.

Step 3: Step 2:

Add the three last round bricks. Add the hanging thing to the top of the "tower" and attach the antenna sideways.
