• Fan
• Inverter
• Purple barrier
• Receiver
• Switch

Overview

In each corner of the room, a contraption involving an Emitter pre-connected to two Receivers can be activated and deactivated thanks to a Blue door. Both blue boors are connected to a set of Switches in the center of the room in a flip-flop fashion: when the door blocking the blue Emitter is open, the red one is closed and vice versa.

The Receivers control a set of Blue doors accessed via a Fan. A first door is controlled by the red Receiver on the right-hand side contraption. Behind it, an horizontal blue door serves as a makeshift draw-bridge; it is controlled by the red Receiver on the left-hand side contraption. Finally, a pair of doors block the passage to the Progress Wheel; they are controlled by the blue Receivers.

Solution

[ solution ]

• 
  Turn on the Switch to open access to the blue Emitter.
• 
  Take one of the Connectors and link the blue connector to the blue Receiver in the middle of the room.
• 
  Take the Connector again, and connect it to both connectors in the corners, as well as the Inverter.
• 
  Take the other Connector and use it to link the static connector on the right-hand side to the Inverter as well as the blue Receiver just below.
• 
  Turn off the Switch to let the red Emitter go through.
• 
  Here is what the setup looks like at this point. The beam from the Connector to the blue Receiver cuts off the one going to the blue-side contraption, preventing the red Receiver that would close the drawbridge from being powered.
• 
  Jump onto the Fan and cross the bridge. Turn on the Switch and finish the puzzle.
• 
  Here is what the setup looks like at this point. The Connector receives both blue and red, preventing it from emitting anything and allowing the blue beam to go through, powering the blue Receiver on the red side and opening both Blue doors.
