Building the tabletop fan

Before building this fan using your LEGO bricks from the LEGO BOOST kit, let's look at the elements needed to build this fan:

• BOOST Hub
• Motor
• The wings of the fan

Great! We will be building the tabletop fan shown in the following figure:

Figure 2.1 – Building a tabletop fan with a LEGO BOOST kit

Follow these steps to build this tabletop fan. Make sure that you select the right pieces from your kit, as mentioned in the building instructions:

1. Take your LEGO BOOST Hub. Make sure that the BOOST Hub has fully charged batteries in it:
   

    

   Figure 2.2

2. Take five 4x6 bricks and stack them on the BOOST Hub, as shown here:
   

    

   Figure 2.3

3. Take two 1x6 plates (orange) and place them on the top of the stack:
   

   Figure 2.4

4. Now, take the external motor and mount it on the orange plates that you just attached:
   

   Figure 2.5

5. Now, take a 1/2 bush and one 3M yellow cross axle and attach them to the motor:

6. Take a 2x2 round brick and insert it into the 3M axle:

7. Take a 2x6 plate and attach it to the white brick with a cross:
   

   Figure 2.8

8. Take two 2x3 white plates and attach them to the 2x6 blue plate:
   

    

   Figure 2.9

9. Take another 2x8 plate and attach it between the two white plates. This will form the base for the fan's wings:

10. Take four 2x6 black bricks with bows and attach them to the white and gray plates. These are the wings of your fan:

11. Take four orange 1x2 plates and attach them to the fan's wings:
    

     

    Figure 2.12

12. Take a 2M cross axle and one white brick with a cross. Attach it to the gray plate, as shown here:
    

     

    Figure 2.13

13. Take a sprocket and attach it to the 2M cross axle. At this point, your tabletop fan is ready to use! Connect your motor to port C:
