Working on several pixel ring designs . This is my latest design to help wrangle them for bread boarding my experiments. Got it right the first time thanks to Shapr.

What is a pixe lring?

Is this it?

‘what to use a ARGB pixel ring holder for?’ AI: I assume you mean an ARGB (addressable RGB) pixel ring holder — a mount or PCB that holds an addressable LED pixel ring. Common uses:

  • Custom lighting for PC builds (CPU cooler, case interiors, GPU backplate accents)

  • Desk or room ambient lighting (behind monitors, on shelves)

  • Wearables and cosplay (costume accents, masks, props)

  • Small interactive displays (audio-visualizers, notification rings)

  • Photography/videography accent lighting (colored rim light)

  • DIY IoT indicators (status ring for home automation, server status)

  • Art and signage (animated logos, sculptures)

  • Learning projects (programming LED animations with microcontrollers)

Quick tips:

  • Use a compatible controller (e.g., Arduino, ESP32, or dedicated ARGB controller) that supports the LED protocol (WS2812/APA102/etc.).

  • Provide a suitable power supply (5V or 12V depending on pixels) and add a level shifter if needed.

  • Include a large capacitor and a resistor on data line to protect LEDs.

  • Plan mounting: thermal pads or standoffs if near PC components to avoid shorts.

You have a fancy PC case with colored LEDs in the fans? Addressable RGB LEDs. Essentially LED with a tiny MCU inside to intercept incoming data from a one wire input scheme for color and intensity information. The first in a string is 0, next is 1… Fun and relatively easy to use. They work in strips or arrays too.

I built that because holder because I am working on a phone app to run a Seeed (tiny computer) via Bluetooth to control each fan’s LEDs independent of the computers motherboard. Takes the load off lesser spec systems but gives you fun way to make each fan do a different thing, control color effects etc.

Some use bloated software to control them.

Retired and have nothing better to do. If successful I will release it for everyone to copy and make it or modify it if they desire. Target is hobbyists like me.
