How To Make Electric String winder (Firki) for Kite Festival
Today we will be looking on How to make Electric String winder For Kite Festival or flying which is very helpful tool using dc motor.
Who Doesn’t love flying Kites? But the sad part of kite flyers is once their kite reaches sky limit all the thread will be in air! And once you enjoy flying kite all these should be rolled back again.
Later everything needs to be withdrawn this word might put few to worry a little, Iam talking about length of thread which was let free in air, since it’s a hectic task to wind all the thread manually by hand to simplify complexities this Firki aka string winder was made.
Today here I will be showing you this awesome idea about make electric string winder which also can be considered as craft idea from DC Motor, which you can try at home and I can guarantee that you will be satisfied with this gadget to the core, So without wasting time let’s Start making Electric string winder.
How Does Electric string winder works?
Definitely it’s a burdern for kite flyers to wind(winding) all the thread manually
This job is simplified with Firki or charkhi or string winder
It is basically a tube rolling with some low torque which collects thread/strings
Spinning speed depends on type of DC Motor used
Motor which I use has good torque popularly known as 775 motor
Power will be supplied from rechargeable batteries, Controlled by simple on/off switch
Can Wind and unwind very long length thread in matter of minutes
Requirements to make string winding machine
DC Motor iam using 775 Motor also called as Drill motor
Lengthy steel shaft recycled from Old radio Antenna
Cardboard tube of required Diameter
Sand Paper for enhancing grip on Cardboard tube For Understanding throughout I will be calling it as roller
MDF Wood or Plexi glass for bottom supports, Super glue and Hot glue
Few extra pieces of Cardboard for filling gaps if any!
Building steps for making electric Firki
Roller For Making Electric String winder
Roller will be main part which collects thread from kite which will be flying in sky, the power(toque) from motor will be directly delivered to roller hence there is no any torque loss which might occur in case of gear usage.
To make roller cardboard tube is covered with sand paper, I used fine grain sandpaper
Using paper glue spill glue on all the sides of cardboard tube, Stick sand paper on glued sides, Wait until dry
Once dry mark and cut 2 cardboard circles slightly larger than size of Roller
Make hole on either sides of cardboard roller, Insert steel shaft, Using hot glue bond the objects
Making Supports
To make support I use MDF Wood
Since one end of steel shaft will go to DC Motor shaft while other is free it needs support
You can see that I used old emergency lamp body parts, Free end of steel shaft will rest here
On the other hand to support weight of motor I used cut pieces of MDF Wood, Coupled using Hot glue, Use super glue wherever necessary
Circuit Connections
I used simple switch circuit to power on and power off this string winder, Recycled battery from old laptop battery to power motor
2 batteries connection in series so that 7.v output is obtained, Make a Simple switch circuit to power these project
How to make simple switch circuit for Electric string winding machine
Suppose you have a simple on off switch, battery and motor
One end of motor goes to battery, Other end of motor is connected to one terminal of switch
From other terminal of switch extend wire to other side of battery
Make sure your switch is off before making any connections, Now Switch on Meanwhile your motor starts to work
Hurray that was tutorial for those who didn’t knew about making circuit
Note: You can’t use Gear motors for making this since we want rotations in both the directions
If u wind enormously large amount of thread here it will be directly used in flying kite
When the roller is not provided with any power if spins in direction of force
This is what we need
But Gear motor shafts are difficult to spin manually, Hence I chose/ you should consider using 775 motor
More the self weight of roller more smooth our project works
Once all the Criteria along with Circuit is made, testing out string winder will be leftover task which is exciting part , Let’s do that!
How to use Electric String Winder machine
Pre roll required amount of thread into roller I prefer to make it full!, Once roller is full
Tie end of thread to your kite Now enjoy flying kite remember that sky is limit!
It’s a fact that one cant use entire length of wire completely as no kite can go outer atmosphere!
Once you feel satisfied with height your kite has gone into It’s time to test our project, Switch on the button Motors starts spinning the roller
Your kite will be pulled from sky in matter of minutes With all the thread arranged in neat manner
That was all about tutorial on how to make electric string winder

Let me explain sole purpose of making this project, there is a festival in india where they arrange kite flying completion I have seen many using manually cranked string winders, and you can imagine how time consuming the task might be to pull very lengthy string from sky
I made small alteration to project which was making it automatic using DC Motor, Selection of Dc motor was not easy as many factors account here which I have mentioned earlier above
I hope you enjoyed reading this, let me know in comments if you have any queries. Also Loving to hear back from you about how did this project work for you, Have a good day, Share this idea wqith your needy friends, Happy Making
