Overview

This project consists of a PCB board designed in KiCad and an enclosure designed in OpenSCAD, which can be 3D printed. The circuit allows users to adjust the intensity of red, green, and blue channels of an RGB LED using potentiometers, creating a full range of colors.

Features

• RGB Color Mixing: Adjust potentiometers to mix red, green, and blue light.
• Custom PCB Design: PCB board designed using KiCad.
• 3D Printable Enclosure: Box designed in OpenSCAD for housing the PCB.

Hardware Components

• Electronics:
  • 1 x Common Cathode RGB LED
  • 3 x Potentiometers (e.g., 10kΩ linear taper)
  • 3 x Current-limiting resistors for the RGB LED (calculate based on your LED specs)
  • 3 x Rocker switches
  • 1 x PCB (design files included)
  • 3 x AAA battery
  • Wires and connectors as needed
  • Some M2 screws
• Tools Required:
  • Soldering iron and solder
  • Wire cutters/strippers
  • Multimeter (optional for testing)

Components examples:

• Red rocker switch
• Blue rocker switch
• Green rocker switch

Enclosure Design

• Software: OpenSCAD
• Files: Enclosure design files are located in the /openscad_src directory.
• Printing: Compatible with most FDM 3D printers; designed for easy assembly.

PCB Design

• Software: KiCad
• Files: PCB board design files are located in the /kicad_src directory.
• Ordering: I ordered mine from PcbWay using quick setup feature and default settings.
