DIY Turntable: From Dusty Record Player to 'Lazy Susan'

Turning an old record player into a variable-speed turntable by replacing its motor with a wiper motor. The motor is controlled via a LM2596HVS-based buck converter module with a 1N4001 fly back diode. Motor speed is controlled with a potentiometer mounted in the front panel.
An output at the back allows usage of the 12 V input for lighting.
Inspired by @boylei, who uses a turntable to show of his awesome creations! I highly recommend a visit.

Tinkering and Despair go hand in hand when it comes to this kind of project, especially since I rarely really know what I'm doing.
Despair Level: 2/10 It was pretty straight forward
