Homemade turntable for vinyl discs
Step 1: Introduction
I wanted to show them a turntable or turntable, as they want to call it, done by me in its entirety, and after much work I can say that the result exceeded my expectations.

The motor was extracted from a cassette player, has 4 pins, in two of which a potentiometer is connected to regulate the speed.
The strap, not getting the measure I needed, I cut a motorcycle camera and it was more than good.
