You have a fidget spinner but you're bored by spinning it manually ! Well this trick will turn an ordinary spinner into a battery powered / Motorised Spinner .
Here's how i did it.
Step 1: Motor Instead of Bearing
Yeah , just pop out the bearing and put a motor instead , you can use some double sided thick tape if your motor does not fit perfectly .
but wait now how you gonna power it ?
Step 2: How Did You Managed to Spin the Whole Motor and Power Simultaneously ?
well , i used conductive copper tape for that ,for details check the video.
