Portal 2 achievement guide - part 1

I am just about done with my achievements in portal 2, so why not share some guidans for those of you that might need help. Of course I wont do the ones you get for completing tests and the game etc. In this first part I'll do all the achievements you can get in Chapter 2, chamber 6. So if you want to do all of these at the same time read all three before you begin, this is important! Good luck.

Final transmission
The first thing you have to do here is when you are at the end of the room, press the button and catch the radio that comes flying. Then you make portals so you get over to the starting place, and then make portals like shown in the picture below, then just fling your self on the aerial faith plates. Where you will end up is in a secret room, the radio will change it's transmission and then you are done.

Drop box
This is one of the easiest. You simply have to drop a cube on a button without touching the cube, so all you do is place a portal under a cube and over a button. When you come to the end of the room and press the button to release the garbage and again press is to get the box, put a portal on the first plate it hits and one over the big button.

Pturretdactyl

Here you have to use an aerial faith plate to launch a turret. Simply catch the turret who comes flying with the junk (to catch both the radio and the turret it might be easier to place portals where you do in drop box so everything lands on the button). Go and fetch it and make your way back to the starting place to use that faith plate, or you can try to drop it on the one that is right beside you by the button.
