Motorized Hand Fan (Trash to Treasure Entry)

This project is our entry for the "Trash to Treasure" contest. The premise of which is to craft something inovative and useful out of nothing but recycled materials. So what day-to-day object is better fit for this competition than a motorized handfan? Our project, The Motorized Handfan is consisted primarily of cardboard, and plastic, with some simplistic wiring. The requisite materials and procedures will be listed bellow in an orderly manner.

Bellow are the necessary objects needed to make this fan.

Additional requirements/suggestions will be put inside []

1. A large panel or box of cardboard (1~2x)
2. A glue gun (1x)
3. Glue sticks for the glue gun (3~4x)
4. A cutting tool (1x)
5. A motor (1x) [Preferably smaller than the battery]
6. A pair of wires (1x, or 2x depending on the length of the fan) [!Has to be compatable with both the motor and battery!]
7. A battery (1x) [Preferably a cylindrical or rectangular shape]
8. A 1L alcohol (sanitizer) bottle (1x) [Preferably made out of plastic]
9. Colored markers (1x) [Preferably a pronounced color]
10. Tape (1x).

Here is a step by step guide on creating the fan blade! You will need: A 1L alcohol bottle, a glue gun, any cutting tool, and a marker. You may preheat the glue gun beforehand if prefered.

Additional requirements/suggestions will be put inside []

1. Prepare the 1L alcohol bottle.
2. Draw the outline of the fan blade with a marker. [Recommended to use a real fan blade as reference]
3. Cut it out using your cutting tool.
4. Use the cut out and marker to draw another outline, then cut it out. [Repeat this two times]
5. Curve the blades slightly. [Recommended to use a fan blade as reference]
6. Remove the cap of the 1L alcohol bottle.
7. Prepare your glue gun. [Preferably preheated before use to minimize waiting]
8. Mark the centre of the cap with a marker. [Measurments are optional]
9. Glue the fan blades' slender end onto the marked centre. [Try to equally distribute the fanblades]

For the second step, you will need: a battery, a pair of wires, a cutting tool, a motor, and some tape.

Additional requirements/suggestions will be put inside []

1. Prepare the battery.
2. Connect the pair of wires to the battery.
3. If the wire length is deemed insufficient, interwine the two edges of the two wires. [Refer to the image above, and its notes.]
4. Secure the link with tape.
5. Connect the wire system to the motor.
6. Turn on the battery to check if the motor spins. [If it does not, review the wiring to check if it is in the right place]

The third step requires cardboard supplies, the Motor Mechanism from earlier, cutting tools, a marker, and a glue gun.

As always, other suggestions will be put in []

1. Prepare your cardboard supply.
2. Place the battery of the Mechanism on the cardboard and draw a slightly bigger outline than it.
3. Repeat the same thing for all 4 of its sides exept the top part and wherever the battery's switch is located. [NEVER COVER THE BATTERY'S SWITCH]
4. Cut them all out with your cutting tool.
5. Using tape, connect all 4 cardboard cutouts from the inside.
6. After all inner sides are connected, apply the glue gun to the outer corners to complete the battery holder.
7. Place the battery inside the holder.
8. Poke a hole into one of the cutouts.
9. Trace the outline of the bottom of the battery with a marker and cut it out.
10. Cut out a thin strip of cardboard [about the length of the bottom of the holder to the hole]
11. Connect both cutouts (the strip and the bottom) with tape. This will be the closing hatch.
12. Connect the holder and the closing hatch with tape, so that the bottom of the holder can open and close.
13. Apply glue to the thin strip, until it is pointed. [Wait for it to dry]
14. To close the closing hatch, input the pointed edge into the hole.

This is the last step of making the fan. All you will need for this step is cardboard, a glue gun, and cutting tools.

1. Get the finished Battery holder.
2. Cut out a long piece of cardboard (roughly the width of the Battery Holder) to the desired length. [This will be the basing for the fan structure, refered to as basing]
3. Use the glue gun to stick it to the back.
4. Align the motor and wires to fit within the piece of cardboard. [1/2 of the cardboard (above the battery holder) will be the neck, and the other half, the fan]
5. Cut out two equal lengths of cardboard (roughly half the length of the piece). [This piece will be refered to as the equal-length piece]
6. Cut out another piece. (The same length as the previously cut pieces, and the same width as the Battery Holder.) [This piece will be refered to as the wider piece]
7. Glue the equal-length cardboard onto the basing, so it is adjacent to the battery holder.
8. Apply glue to the top corner of the two equal-length cardboard and stick the wider piece ontop of it.
9. Repeat the process again for the upper half, but do not cut out the wider piece.
10. Glue the non-functioning (the part that doesn't spin) onto the basing.
11. Flip the fan upright so that the Battery Holder comes at the bottom.
12. Cut out a small cardboard square.
13. Glue the top edges of the equal-length cardboard.
14. Put the small square ontop of it.
15. Glue the Fan blade onto the functioning motor.

And that marks the end of creating the Fan!
