Just a cool toy, and can be used at discos, the design is very simple,
we will need:
1 power supply (charging for phone)
2 Cassette drive pulley from a tape recorder of the Sonata series
3 The drive motor fits perfectly into the pulley.
4 Any motor (I took with a toy)
5 Pair of LEDs (any)
This design can be improved as you wish:
I attached a speed regulator: I’ll tell you how to do it in the next article
Filmed on the phone, do not judge strictly this is my first article ....
