how to make a simple generator

Fidget spinner electric generator

fidget spinner is a stress relieving toy that consists of a bearing in the center of a multi-lobed  structure made from metal or plastic.


Fidget spinner simple electric generator. How to make a simple electric generator using a fidget spinner

Step 1.


fidget spinner , 3 neodymium magnets, a coil without core – we used a coil from a syncronous motor 230 V, inside A4 lamintor and  microwaves – turntable motors + led

Step 2.

fix the neodymium magnets on the fidget spinner

conect the led to the output wires of the coil

In the rows below we wish to show how can a powerfull fidget spinner generator can be created. It will generate 100 Volts Ac at the start and it will be able to light a led bulb 230 V 9 W . An educational project, using just a few materials.

Materials :

1. fidget spinner

2. coil iron- less – inside syncronous motor 230 V – microwaves and A4 laminators

3. glue

4. bearing ( neodymium sphere 30 mm metal holder)

5. wires

6. three neodymium sphere 13 mm ( extra weight for the fidget spinner)

7. led bulb 230 V 9 W

8. wires

9. plastic holder ( used to fix the fidget spinner generator )

10. voltmeter

Operations :

1. fix the fidget spinner plastic holder on a box using glue

2. fix the bearing on the fidget spinner ( 30 mm neodymium sphere metal holder )

3. fix 3 neodymium spheres on the fidget spinner ( extra weight)

4. attach the 30 mm neodymium sphere between poles on the bearing ( the glue one )

5. connect the voltmeter in Ac mode to the coil output

6. connect 9 W led bulb 230 V to the output coil using wires you can use related led bulb 3 W , 7 W also

7. assembles all the components

Important :

when you are attaching the 30 mm neodymium sphere on the metal holder ( bearing glued on the fidget spinner), fix the sphere between the magnetic poles to obtain the maximum voltage.

fidget spinner generator 3 in 1 – now you can configure your fidget spinner generator (three choices)

the micro generator is using 3 neodymium spheres and 3 neodymium discs

(led and small coil iron less )

Materials :

1. fidget spinner

2. 3 neodymium spheres 13 mm

3. 3neodymium discs



6. small coil iron -less

Operation 1:

1. fix the neodymium spheres (3 pieces) on the fidget spinner

2. conect the led to the output coil wires

Operation 2.

1. Fix the eodymium discs on the neodymium spheres

2. put the coil near the running fidget spinner

the fidget spinner generator is now ready
