I cleaned my Kotronic jukebox and now it’s time to give this an upgrade. I will leave all of the original electronics intact and still working but I will add the WS2812 led strip inside the bezels, top and centerpieces. these will be controlled using an Arduino to simulate the “bubbler” bezels from the original wurtzinger/rock-ola jukeboxes from the ’50s.

DIY PC PSU to Bench / Project Power Supply
Computer power supplies typically cost around $30, while dedicated lab power supplies often come with a much higher price tag—$100 or more. However, by repurposing inexpensive or even free ATX power supplies found in discarded computers, you can create a highly capable lab power supply without breaking the bank. These units offer impressive current outputs, built-in short-circuit protection, and surprisingly stable voltage regulation, especially on the +5V rail.
This makes converted ATX power supplies an excellent choice for hobbyists, students, or anyone needing a reliable bench power source on a budget. With a bit of modification and setup, you can turn a common computer PSU into a versatile lab supply that rivals many commercial options in both performance and safety features.

Arduino Composite TV output Shield
Shields are add-on boards designed to plug directly onto the Arduino’s main PCB, expanding its capabilities without the need for complex wiring or additional hardware. These shields can add everything from network connectivity and motor control to audio output and displays, making the Arduino platform incredibly versatile for a wide range of projects.
In addition to its usual input/output functions, the Arduino is also capable of generating a composite video signal, allowing you to display basic graphics or text on a standard TV using a simple yellow RCA video cable. In this guide, I’ll walk you through how I built my own composite video-out setup for the Arduino in under 15 minutes, using just a few basic components and minimal code.
