How this hand held fan works

Toy dc motor is attach to propeller which is made from plastic that’s completely harmless if touch while it’s working

Rechargeable battery provides option to carry this fan anywhere

Lithium ion battery which is recycle from old laptop battery is connect to charging module

Gives large backup time as we know lithium ion batteries are good charge keepers

Here interesting part being i use 4 propellers instead of one as the force of air blowing will be more higher

If you have any ideas for upgrades i will consider your ideas, Let me know what you think

I use piece of hard cardboard from bind cover which measures 11cm by 11cm

Mark mid point by drawing lines as shown on visual above

From corner mark 1cm apart line and draw motor frame outline

I use measurement from my motor frame which will be later fixed here Mark all these using pencil and ruler later cut using paper cutter

After these steps color front and back part according to your taste

From above visual we now have slots for toy dc motors

Attach motors carefully as we have much spaces between edges

Here after fixing to slots use wires to connect motors parallel

solder wire in parallel to motors as series connection need higher power input source

Positive of all motors will be on one side hence solder piece of wire next to one another

Negative will be on other side and repeat same steps

Later make holder for this fan from rectangular tube of cardboard alternatively pipe piece can be added

For making this rechargeable i use lipo battery charger also known as 18650 charging module

Add a switch between all these components which i think is not difficult to make

Make it all firm using hot glue, dual side tape also serves this purpose

All open wire connections are covered using insulation tape or hot glue

Lastly attach propellers to motor shaft and switch on to enjoy some air!
