Addressable LED Ceiling Star Map Variant 3 Kit with ESP32
Addressable LED Ceiling Star Map Variant 3 Kit – A Personal Planetarium with ESP32–Driven Twinkle
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform any ceiling into a living star field where each point of light twinkles independently — just like the night sky. This kit equips you to map your own star positions using WS2812B addressable LEDs and an ESP32 microcontroller that pulses brightness with organic, random-seeming variation. Whether you want to recreate a specific constellation, mimic the Milky Way, or design a personalised celestial canvas, the Variant 3 kit delivers a completely custom, immersive ambient installation.
What You'll Build
You’ll craft a distributed LED array mounted directly onto your ceiling, with every star individually addressable via a single data line. The ESP32 runs firmware that modulates each LED’s brightness in subtle, asynchronous fades — no repetitive flashing, just continuous twinkling. The result is a ceiling that breathes with light, creating a deeply relaxing or awe-inspiring atmosphere. A discrete control box houses the power supply and microcontroller, and three tactile buttons let you cycle through animation presets or adjust global brightness using the potentiometer.
What You'll Learn
- Addressable LED protocol timing and data line management using the FastLED library on ESP32
- Microcontroller programming for non-linear brightness curves and pseudo-random twinkle algorithms
- Power distribution design for long 5V LED runs — capacitor placement, resistor inline protection, and 10A supply wiring
- Through-hole soldering and prototyping on PCB boards to build a durable control module

Who This Kit Is For
This advanced kit speaks to makers who already know their way around a soldering iron and an Arduino IDE — perhaps as a step up from earlier LED projects. It’s ideal for interior design experimenters, working professionals who tinker with embedded systems, and B.Tech ECE/EEE graduates or hobbyists from India’s engineering campuses (IITs, NITs, VIT, BITS) wanting a deeply satisfying display-art build. If you’ve ever wanted a personal planetarium that responds to the rhythm of your code, this is your project.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Open the AI companion from your phone — it’s trained on the exact wiring, code, and troubleshooting steps for this kit. You can also drop a message on WhatsApp and a human will step in within hours.
Can I design my own star layout or mimic a real constellation?
Absolutely. The ESP32 code is fully open and well-commented. Map LED indices to coordinates of any constellation or free-form pattern, and the AI companion can guide you through assigning star positions in the firmware array.
How do I mount the LED strip on the ceiling without permanent damage?
The strip’s 3M adhesive backing holds firmly on clean, dust-free surfaces. For rental-friendly installation, use low-tack painter’s tape or small removable clips. The controller box can sit on a shelf or be wall-mounted.
Does the kit support multiple twinkle modes or brightness settings?
Yes. The three tactile buttons let you cycle through pre-loaded animation presets (subtle, active, calm) and the potentiometer adjusts overall brightness in real time — all without re-flashing the ESP32.
WS2812B LEDs individually addressable at star positions on ceiling. ESP32 pulses brightness as twinkling.
