Working Tiny Fan With a Power Wall Plug
Introduction: Working Tiny Fan With a Power Wall Plug
This Tiny fan functions the same as the original fan, the fan speed can be felt even though the size is so tiny and the funny thing, this fan has a cable with an electrical plug that must be plugged into the wall plug to function.
Supplies
Actually this fan is made from scrap, so I can't give the purchase link for a supplies.
* motor dc mini coreless
* big and little dring straw
* small cabletransparent hard plastic
* card scrap plastic
* bottle cap
* metal wire
* micro switch on/off
* 3,7 battery
* male & female pin connector
* soldering tools
* Glue
Step 1: Making a Head Fan
This step you need:
* coreless motor,
* big straw
* little straw
* super glue
* soldering
First you enter the motor into a large straw, it is very fit in size, measure the length according to the length of the motor, then cut it according to the size of the motor, adding more space to install the cap, after that you need a small straw for the fan head pole, measure and cut approximately according to the height of the fan you want to make, don't glue it first, before you have to connect the motor cable if your motor cable is short, connect the motor with a cable that is at least 20cm long, strengthen it with solder
After you connect your motor cable, put the motor back into the big straw by first entering the abel into the small straw. look at the picture, strengthen it using super glue,with a plastic card, cut a round shape according to the size of a large straw as the back cover of the motor, fix it with glue. 98
the head of fan is ready.
Step 2: Making a Base
This step you need :
* bottle cap
* cutter
* micro swicth on/off
* soldering
* super glue
Take the bottle cap, then cut the bottom of the cap at an angle so that if it is placed on the floor, the top surface of the bottle will look slanted, use a cutter to cut it carefully when doing this, then also make a hole, there are 3 holes that must be made, the first hole is for the on/off switch, made in the shape of a box, the size is adjusted to the on/off switch, the second hole is slightly at the back of the lid, the round shape is the size according to a small straw for the fan neck, the third is a round hole small just behind the side of the bottle for wire.
In this step you need to connect the wire to the micro switch on/off by using a soldering iron. don't forget to install the fan head and attach the on/off switch to the base that has been made.(wiring schematic on pic gallery)
Step 3: Making Fan Blade
This step you need :
* transparent hard plastic
* cable tube
* plastic tube (i make from plastic gear pic.2-3)
* super glue
* cutter
Now we will make the fan blades, first time we make the fan blane center, because the motor shaft is very small so I use a cable tube to fit enough on the plastic tube, The plastic tube that I use is from pieces of used gear, only taking the tube part.
We will make fan blades with thin transparent mica plastic, before that, first make a fan pattern on paper, then cut and draw the pattern on plastic, make 3 and cut, make sure everything the same size. then pitch the blades at a slight angle, remember the fan rotation is clockwise, so don't put the blade tilt wrong, make sure when the fan rotates the wind will point forward, if it's upside down the wind will point backwards, but don't worry if it's upside down and not can be corrected, we can change the direction of rotation of the fan in the end, install the every bade using super glue, make sure it's really strong. 996
