Just a cool toy, and can be used at discos, the design is very simple,
we need:
1 Power supply (phone charger)
2 Cassette drive pulley from a Sonata series tape recorder
3 The motor from the disk drive fits perfectly into the pulley.
4 Any motor (I took it from a toy)
5 Pair LEDs(any)
This design can be improved as you wish:
I attached the speed controller: I’ll tell you how to do it in the next article
