This can be done with WLED, there’s a few examples of how on this page under the “non-addressable” section.

You’d need the WLED board, as well as some additional hardware.

use an Arduino and some mosfets and limiting resistor, those are not individually addressable but easily controlled by a nano and some extra components to handle power distribution. Google arduino controlled RGB strip for ideas.

Reverse Engineering an LED Light Strip: A Step-by-Step Guide

Reverse engineering an LED light strip can be a fun and rewarding project for hobbyists and DIY enthusiasts. With the right tools and a bit of patience, you can dissect an LED light strip and understand its inner workings. In this article, we’ll guide you through the process of reverse engineering an LED light strip, including the steps to follow, the tools you’ll need, and the benefits of doing so.

Why Reverse Engineer an LED Light Strip?

Reverse engineering an LED light strip can be useful for several reasons:

  1. Cost savings: By understanding the internal components of an LED light strip, you can potentially reproduce it at a lower cost.
  2. Customization: Reverse engineering an LED light strip allows you to modify or upgrade the design to suit your specific needs.
  3. Troubleshooting: Understanding the internal components of an LED light strip can help you troubleshoot issues or repair faulty units.
  4. Learning: Reverse engineering an LED light strip is a great way to learn about electronics and the inner workings of LED lights.

Tools and Materials Needed

To reverse engineer an LED light strip, you’ll need the following tools and materials:

  1. LED light strip: Choose an LED light strip that you want to reverse engineer.
  2. Multimeter: A multimeter is essential for measuring voltage, current, and resistance.
  3. Soldering iron and solder: You’ll need a soldering iron and solder to desolder components.
  4. Pliers and wire strippers: Pliers and wire strippers will help you remove components and trim wires.
  5. Breadboard or PCB: A breadboard or PCB can be used to test and reassemble the components.
  6. LED driver: If your LED light strip has an external driver, you may need to desolder and remove it.

Step-by-Step Guide

  1. Disassemble the LED light strip: Carefully remove the casing or outer housing of the LED light strip. You may need to use pliers or a screwdriver to remove screws or clips.
  2. Identify the components: Examine the internal components of the LED light strip, including the LEDs, PCB, and wiring. Note the type and number of components, as well as their connections.
  3. Measure the voltage and current: Use a multimeter to measure the voltage and current flowing through the LED light strip. This will help you understand the power requirements of the LEDs and the driver.
  4. Desolder the components: Use a soldering iron and solder to desolder the components, such as the LEDs, resistors, and capacitors. Be careful not to damage the components or the PCB.
  5. Remove the components: Use pliers and wire strippers to remove the components from the PCB. Take note of the pinouts and connections.
  6. Test the components: Use a breadboard or PCB to test the individual components, such as the LEDs and driver.
  7. Reassemble the components: Once you’ve tested and verified the components, reassemble them in the original configuration or modify them to suit your needs.
  8. Rebuild the LED light strip: Reassemble the LED light strip, making sure to connect the components correctly.

Tips and Precautions

  • Handle components with care: Be gentle when handling components to avoid damaging them.
  • Use the correct tools: Use the correct tools, such as a soldering iron and solder, to desolder and reassemble components.
  • Be patient: Reverse engineering an LED light strip can be a time-consuming process, so be patient and take your time.
  • Consult documentation: Consult the documentation or manufacturer’s instructions for guidance on the components and connections.

Conclusion

Reverse engineering an LED light strip can be a fun and rewarding project that allows you to understand the inner workings of an LED light strip. By following the steps outlined in this article, you can disassemble and reassemble an LED light strip, learning about electronics and the components that make it work. With this knowledge, you can customize or reproduce the LED light strip to suit your needs, or troubleshoot and repair faulty units. Happy reverse engineering!

Picture for reference. I want to be able to fully customise the light strip. I tried using nRF and LightBlue but couldn’t find the lights in the lists. It is used by an app called istrip+
