Now that we know the circuitry works, let's put everything in its place. We'll use some steel and nylon fasteners as well as a few spots of glue.
Unplug the battery to begin the assembly process. It's safer that way.

Mount the components to the interior of the enclosure in the order shown.
1. Fan
- Orient the fan with the wires exiting towards the top of the enclosure.
- Use four M2.5x16mm steel screws, flat washers, and hex nuts.
- Place the washers and nuts on the interior side of the fan.
2. N-Channel MOSFET
- Position the MOSFET so the pins and connected wires are to the right.
- Attach with one M2.5x10mm nylon screw and hex nut.
3. micro USB Panel Connector
- Attach using the included steel screws.
4. PowerBoost 500C
- Position the board with the battery connector towards the enclosure bottom side.
- Secure with four M2.5x6mm nylon screws.
5. Li-Po Battery
- Mount on the bottom side of the enclosure using two very small dots of blue tack putty.
- Wait to plug the battery wire into the PowerBoost until all components are installed.
6. PIR (Motion) Sensor
- Orient the sensor with the two adjustment controls facing outwards.
- Attach to the right side of the enclosure using two M2.5x6mm screws.
7. On/Off Switch

8. USB-A Panel Connector
- Attach with the included steel screws.
At this point, all the primary components are attached. Re-connect the battery to the PowerBoost and test to see that the extractor is working properly.

Next we'll attach the filter support rods, the prismatic window plastic, and finally the activated carbon filter material. Almost done!
