In this Instructable i am am going to teach you :- How to make a battery powered fidget spinner, the spinner spins for 12 hours continuously and at very high speeds.
It's an cheap project which hardly takes 30 mins to complete.
It hardly requires any advance tools or gadgets.
Step 1: Watch the Videos.
Before you start this instructable, you must see all the videos of the spinner.
The videos will give you a brief clue about the project.
But make sure you watch them, you are gonna love the videos.
Step 2: Materials and Tools
As I informed you before that the project is quite cheap, so it does not require many materials or tools.
1. 3 AA battery cells
2. One 1.5v motor
3. One small bearing( I got one from a yo-yo)
4. Two nuts
5. One LED of your choice.
6. One bead
Step 3: Bearing System...
You must be wondering that we already have a motor, so why do we need a bearing?
It's because we need to hold the fidget from the top and the bottom. So the motor provides motion on one side and the bearing on the other.
As you can see in the first pic, I have pasted the two nuts with epoxy glue to levitate the bearing.
In the second and third pic the bearing is pasted on the nuts with epoxy glue.
The fourth and fifth pic show that i have stuck a cylindrical beed in the middle of the bearing to make the spinner more ergonomic.
Step 4: The Battery Balancing.
This is the most important part of the project.
The batteries are the source of power and also the weight distributors.
Arrange the batteries as shown in the first three pics.
Make sure that no like poles are facing each other.
I used a hot glue gun to stick the batteries to the motor.
NOTE:- The key to a perfect balance is to paste the batteries in a proper level.
Don't use little glue, as the fidget will spin, it will gain momentum which would be enough to rip apart the batteries.
SO USE A LOT OF GLUE.
If you don't have a hot glue gun, then use double sided tape for the same purpose, but I would still recommend you to use a glue gun if possible.
Step 5: Making the Connections...
You have successfully completed the difficult part.
All that is left is some minor touches.
Connect the wires as shown in the pictures above.
I did not have a soldering iron, so i just used some cello tape to connect the wires to the batteries.
Step 6: Finishing Touches...
I connected a red LED between two terminals with a little bit of cello tape.(Pic one and two)
On the remaining two terminals I connected two wires without insulation to work as switches.(Pic three and four)
You can clearly see in the fifth pic, how your spinner must look so far.
Step 7: Done!
If you followed the steps correctly, all you have to do is wind the two open wires together and hold the gadget like a normal spinner.
