Preparation materials: 3 different colors and sizes of colored paper, scissors, hole punch, and string.
1. Remove the smaller piece of paper first, fold it in half twice from the middle, then use a hole punch to punch holes as shown in the picture below.
2. Then we remove the larger colored paper and use scissors to cut the edges on both sides as shown in the picture below.
3. Then place the three colored papers in sequence, fold them parallel and continuously, and tie a knot with a rope in the middle, as shown in the figure below.
4. Then we can play with the edge of the beard with our hands and do it a few more times to make the lace more beautiful.
5. Then unfold the entire fan and carry out the final finishing. A beautiful little handmade fan is ready.
How to makea handmade electric fan
Wind turbine fan blades are made of various materials, such as: wood, metal, engineering plastics, fiberglass, etc. . Among them, micro wind turbine blades are generally made by hand from wood, using cold stamping or metal injection molding processes; The blades of small wind turbines are usually made by hand from metal or fiberglass, among which fiberglass blades are the most popular and practical blades. Large-scale wind turbine blades are usually made by hand from fiberglass.
Blades are the most fundamental and critical components of wind turbines. Their good design, reliable quality and superior performance are the decisive factors to ensure the normal and stable operation of the unit.
The manufacturing method ofhe handmade electric fans is as follows:
1. The following materials should be prepared in advance
1. (old tape recorder, electric toy car, etc. The top can be removed)
2. Iron sheets (metal packaging boxes for items such as wine boxes and beverage boxes)
3. . Lollipop sticks or pen refills
4. Pliers
5. Power (power provided when purchasing a mobile phone)
6. cell phone charging
7. Electrical tape
8. Scissors
9. Super glue
2.
1. Use super glue to stick the small motor and power supply together (cannot block the charging port and power output port).
2. Cut the power cord used to charge the cell phone with scissors, mainly using the USB port. And peel off the black and red wires inside the wire. The white and green wires do not haves need to be cut short.
3. Connect the red wire and black wire of the USB interface to the two wires of the motor respectively (the wires are not divided into positive and negative poles, but remember the red wire and black wire). wire on the USB interface because the white and green wires are off) and wrapped separately with tape.
4. Use duct tape to wrap the joints of the two wires together to reinforce them.
5. Connect the USB port to the power supply and check if the small motor works. If it does not light up, there are three possibilities:
(1) The power supply is discharged.
(2) The wire is not connected correctly or incorrectly.
(3) The engine is broken.
6. Let's start by making the fan blades. First, use scissors to cut a long strip of the iron sheet to a suitable size.
7. Cut 4 corners to make fan blades. Don't cutz not too much.
8. Find a small nail and hammer it into the middle of the fan blade.
9. Use pliers to cut off a section of the nail, leaving only 3mm long.
10. Find a lollipop and use pliers to cut about 1cm off the lollipop stick.
11. Add a drop of super glue to the fan blade nail, then insert the lollipop stick into the nail. Wait for the glue to dry. At this point, the fan blade portion is almost complete.
12. Assemble the fan blade part and the motor part together. (There is no need for glue in this step, so it can be easily placed in a bag or pocket)
13 Depending on the running direction of the fan, use your fingers to twist the blades of the fan. make the fan blades spiral. The mini electric fan is now complete.
