Every night, without asking permission, the Moon changes. A sliver grows into a half, the half swells into a full silver disc, and then it quietly wanes back into darkness — a slow, silent rhythm that has been running since before there were people to watch it. I wanted a piece of that rhythm sitting on my desk. Not a static decoration shaped like the Moon, but something that actually behaved like it — a surface as old and rough as stone, and a mind as current as the night sky outside my window.

That's what LUNARA is. It's a Moon, cast entirely in white cement, cratered and imperfect the way the real one is, mounted in a frame and lit from within by 27 individually addressable LEDs. Underneath that cement surface, an ESP32 keeps time, checks the sky, and decides how the Moon should look right now. A small OLED display on the base quietly reports the current time alongside the Moon's real phase — both the name of the phase (Waxing Crescent, Full Moon, Waning Gibbous, and so on) and a small graphic icon of it, like a caption for what the light above it is doing. Connect it to Wi-Fi, and LUNARA stops being a lamp and starts being an instrument: it hosts its own web server, right on the device, letting me reach into the 27 LEDs from any browser and dial in colors, brightness, and animations by hand — no app, no cloud account required.

This is where the project meets the contest. The brief asks for stone, concrete, and cement used in thoughtful, inventive ways — sculptural pieces that explore form and texture as much as structural ones. LUNARA is built around exactly that tension: cement is a material everyone associates with sidewalks and foundations, permanence and mass, not with something that sits on a nightstand and glows. Choosing white cement specifically, and then sculpting it by hand instead of relying on a mold to do the work for me, was as much a statement as a construction decision — proving that a material defined by weight and permanence could also carry something as delicate and constantly shifting as moonlight.

The motivation: transformation, not just illumination

The real pull behind this project wasn't just "I want a Moon lamp." It was the transformation itself — watching a grey, lifeless block of cement become something that glows in the dark like it has its own light source. There's something almost unbelievable about that shift the first time you see it happen: a material you'd normally walk past on a sidewalk, dense and cold and completely inert, suddenly lit from within, throwing soft light across a room the way the real Moon throws it across a landscape. That contrast — dead weight becoming living light — is the whole emotional core of LUNARA, and it's what kept me going through the slower, messier parts of the build.

That transformation happens twice, really. First physically: a plain cast sphere, sanded and grey, turned into a cratered lunar surface by hand, crater by crater, until it stopped looking like a construction material and started looking like a piece of the sky. And then a second time, electrically: that same textured cement, dark and unremarkable in daylight, comes alive the moment the LEDs switch on behind it — every crater catching light differently, the whole surface glowing in the dark the way only something genuinely dimensional can. Seeing a "dead" material like cement hold onto that presence in the dark, glowing on its own instead of just reflecting light, was the moment the project stopped being a build and started feeling like the thing I set out to make.

Why cement, why the Moon

It started with something simple: looking up. The Moon is the one astronomical object almost everyone has a relationship with, whether they think about it or not. No telescope, no dark-sky location, no app required — it's just there, changing shape on its own schedule, mostly noticed in passing. The more I studied close-up photographs of it, the more I realized how much texture gets lost when it's reduced to a smooth circle in a drawing or a plastic lamp. The real Moon isn't smooth — it's beaten up, craters overlapping craters, ridges catching light unevenly. That roughness felt like the actual subject, not a detail to smooth over.

Most Moon lamps on the market are printed plastic spheres with a uniform glow — pleasant, but flat. I wanted something that looked like it had actually been through something, and that ruled out plastic immediately. White cement solved the texture problem in a way nothing else could, and it did it in two distinct stages. The Moon was first cast as a smooth sphere in a mold — a clean base form with none of its eventual roughness. The craters came after, carved and worked into that surface by hand while the cement could still be manipulated, pressing and digging the way a sculptor works a form rather than letting a mold define it. Casting gave the Moon its geometry and structural integrity; carving gave it its identity. Skip the hand-worked stage and it stays a plain grey sphere — no different from any other cement casting.

From sculpture to instrument

A textured cement sphere on its own is still just a sculpture, however convincing. What turns LUNARA into something alive is everything built in behind it:

1. 27 individually addressable LEDs, mounted behind and around the cement shell, giving control over brightness and color at a resolution a single bulb never could.
2. An ESP32 as the brain — enough horsepower to hold a Wi-Fi connection, host a web interface, and run LED animations all at once.
3. An SSD1306 OLED display on the front face of the base, showing the current time plus the real lunar phase — spelled out by name and rendered as a small icon — so LUNARA can tell you what it's doing without opening an app.
4. A self-hosted web server running directly on the ESP32, reachable from any browser on the network, giving full manual control over color, brightness, and animation across all 27 LEDs — individually if I want.

The moment LUNARA connects to Wi-Fi, the ESP32 syncs its clock over NTP and calculates the actual current lunar phase, pushing it straight to the OLED — waxing, full, waning, new, tracked against the real cycle happening outside. The lighting itself stays under manual control through that web interface; it's not a scientifically exact reproduction of lunar color (RGB LEDs can only approximate that), but between the phase the OLED reports and the lighting I dial in through the browser, LUNARA gives me an astronomically informed way to actually respond to the sky, rather than ignoring it.

The cement doesn't change. It won't crack, fade, or need replacing because a trend moved on — that's the permanence the contest is built around. What changes is everything running quietly beneath it: the phase ticking forward night after night, the display updating, the LEDs waiting for the next command. A static material, built to outlast trends, made to host something that never stops moving.

Building the physical Moon turned out to be its own project entirely — casting the white cement sphere, then carving in every crater by hand — and that's where the real story, and the rest of this Instructable, starts.

The printed parts were then checked for proper dimensions, fit, and assembly before moving on to the next stage of the project.

The most important part of this project was finding the right white cement consistency. Before making the final Moon, I experimented with multiple cement-to-water ratios to achieve a mixture that was smooth enough to shape, yet strong enough to hold the detailed lunar texture after curing.

Materials Required

1. White Cement – 500 g
2. Clean Water – 300 ml
3. Mixing Container
4. Mixing Stick or Spatula
5. Gloves (Recommended)

Finding the Perfect Mix

I didn't use the first mixture I made. Instead, I tested several batches with different amounts of water and white cement until I found the consistency that worked best for this project.

After multiple trials, I reached the conclusion that:

500 g White Cement + 300 ml Water provides the ideal consistency for creating the Moon.

This ratio produced a mixture that was:

1. Smooth and easy to mix.
2. Thick enough to hold its shape.
3. Soft enough for detailed wet carving of craters and surface textures.
4. Strong enough to dry into a solid Moon without losing details.

Mixing Process

1. Add 500 g of white cement into the mixing container.
2. Gradually pour in 300 ml of clean water instead of adding it all at once.
3. Stir continuously until the mixture becomes smooth and lump-free.
4. Keep mixing until it reaches a thick, creamy consistency suitable for shaping the Moon.
5. Once the mixture is ready, immediately move on to the wet carving process before the cement begins to set.

💡Tip

500 g White Cement + 300 ml Water was the best ratio I found after several experiments. It provided enough working time for carving realistic lunar craters while maintaining a strong and durable final structure.

Step 4: Pouring the Mixture into the Moon Tray

This step was done immediately after preparing the white cement mixture. I did not wait between mixing and pouring because the cement needed to remain in a workable condition for proper shaping and carving later.

Pouring Process

1. Immediately after completing Step 3, I poured the entire prepared mixture into the Moon tray.
2. I made sure to pour the mixture evenly across the tray.
3. After pouring, I gently tapped the tray from different sides to help the mixture spread into every corner.
4. The tapping also helped the cement settle and level itself naturally.
5. I continued tapping until the mixture reached a uniform level across the tray.
6. Special attention was given to removing trapped air bubbles, as they could create holes or weak spots in the finished Moon.
7. I kept gently tapping and settling the mixture until no obvious air bubbles were coming to the surface.
8. I checked the entire tray to make sure the mixture had reached all corners and areas evenly.
9. I continued this process until I was satisfied with the level, distribution, and bubble-free surface.
10. Once the mixture was properly settled, it was ready for the next stage: wet carving the lunar surface.

💡 Important Tip

Do not wait after preparing the mixture. Pour it into the Moon tray immediately, then gently tap and settle the tray until the cement is evenly distributed and trapped air bubbles have been removed.

Once the cement mixture was evenly settled in the Moon tray, I moved on to creating the craters and rough lunar surface texture. This step gives the Moon its natural and realistic appearance.

🌕 Creating the Craters

1. To create the craters, you can use any smooth, round, sphere-shaped object that fits the desired crater size.
2. Alternatively, you can use your finger to create the crater shapes directly.
3. Gently press the object or finger into the wet cement to form circular depressions.
4. Create craters of different sizes and depths to make the surface look more natural.
5. Avoid making the craters perfectly uniform, as real lunar surfaces have irregular formations.

🪨 Creating the Rough Moon Surface

1. To create the rough and uneven texture of the Moon, gently tap your finger over the cement surface.
2. You can also use a small piece of cotton or a sponge to create a more irregular texture.
3. Lightly press or tap the surface rather than dragging the material.
4. Continue adding texture until the surface starts to resemble the rough, uneven appearance of the Moon.
5. Use the provided GIF/image as a visual reference while creating the texture.
6. Take your time and keep the texture irregular for a more realistic result.

⏳ Drying the Moon

1. Once the desired craters and surface texture have been created, carefully place the Moon in a dark, dry place.
2. Leave it undisturbed for approximately 24 hours.
3. Avoid moving or touching the Moon during this period so the surface details are not damaged.
4. After 24 hours, check that the cement has dried and the Moon has become firm enough to handle.
5. The Moon is then ready for the next stage of assembly and finishing.

💡 Tip: Don't try to make the surface perfectly smooth or symmetrical. The small imperfections, random craters, and uneven texture are what give the cement Moon its natural character.

While the cement Moon is drying and curing, I started working on the electronics and programming part. The ESP32 is the brain of LUNARA and is responsible for controlling the 27 NeoPixel LEDs, OLED display, Wi-Fi, Moon phase calculation, animations, and web control interface.

Instead of simply uploading a large program without understanding it, I divided the code into different functional blocks to make the complete system easier to understand.

1. Library & Hardware Configuration

The first block includes the libraries required for Wi-Fi, the web server, NeoPixels, OLED graphics, and time functions.

The hardware pins and display/LED configuration are then defined:

This configures 27 NeoPixels on GPIO 5 and the 128×64 OLED using I2C on GPIO 21 and 22.

2. NeoPixel & OLED Setup

The code creates objects for controlling the LED strip, OLED display, and web server.

This allows the ESP32 to communicate with all three major parts of the system: lighting, display, and web interface.

3. Individual LED Color Control

Each of the 27 LEDs has its own RGB color value stored in an array.

This makes it possible to control the LEDs individually rather than treating the entire strip as one light source.

4. Moon Phase Calculation

The code uses the current date and a Julian-date-based calculation to estimate the current lunar phase.

The calculated phase is then mapped to one of eight Moon phases:

The eight phases and their index mapping are directly implemented in the code.

5. Drawing the Moon on the OLED

The OLED doesn't use an image file for the Moon. Instead, the Moon graphic is drawn dynamically using circles and rectangles.

Different black shapes are then used to mask portions of the white circle depending on the current phase.

For example, the waxing crescent is created using:

The program therefore changes the OLED Moon graphic automatically according to the calculated phase.

6. OLED Information Display

The main OLED screen is divided into two sections.

The left side shows the current time, Moon phase name, and phase index:

The right side displays the graphical Moon phase:

This creates a compact astronomical information display directly on the 128×64 OLED.

7. Color Presets

The program includes 12 built-in color presets. Each preset assigns an RGB value to all 27 LEDs.

For example:

The selected color is then applied to every LED:

8. Web-Based Control Panel

One of the main features of LUNARA is that the ESP32 itself hosts the control webpage.

The webpage provides controls for:

1. Preset colors
2. Master brightness
3. Animations
4. Individual LED colors
5. All LED colors
6. Live Moon phase
7. Local time

The webpage is stored directly inside the ESP32 program as HTML/CSS/JavaScript.

The individual LED controls are generated for all 27 LEDs:

9. Web Server Commands

Different URLs are used to control different functions:

This creates a simple API between the webpage and the ESP32.

For example:

10. LED Animations

The code contains 10 different animations:

The active animation is selected through:

11. Brightness Control

The web interface can change the overall brightness of the NeoPixel strip.

This allows the brightness to be adjusted without changing the individual LED color values.

12. Wi-Fi & NTP Time

During startup, the ESP32 connects to Wi-Fi and then synchronizes the time using NTP servers.

The timezone is configured for India:

NTP synchronization uses:

13. Main Loop

Finally, the loop() function continuously manages all the different functions of LUNARA.

The loop handles web requests, changes the OLED display after the startup IP screen, periodically recalculates the Moon phase, refreshes the OLED, and runs the selected animation.

🧠 Overall Code Flow

This programming stage gives LUNARA its smart functionality, while the cement Moon continues to dry and cure in parallel.

Once the code was prepared and understood, I programmed the ESP32 using the Arduino IDE. Before uploading the program, I installed the required ESP32 board package, USB driver, and libraries needed by the project.

💡 Tip: If the ESP32 is not detected by the computer, first check the USB cable and then install the USB-to-Serial driver used by your particular ESP32 board.

After uploading the code to the ESP32, the next step is to understand how all the electronic components are connected. The wiring is designed to allow the ESP32 to control the 27 NeoPixel LEDs and OLED display, while the battery and charging circuit provide portable power.

🔌 Main Connections

1. ESP32 → NeoPixel LEDs

1. ESP32 GPIO 5 → NeoPixel DIN (Data In)
2. ESP32 GND → NeoPixel GND
3. 5V Power → NeoPixel 5V/VCC
4. The NeoPixels are connected in a data chain, where the data signal passes from one LED to the next.
5. The ESP32 controls all 27 LEDs individually through a single data line.

The code defines GPIO 5 as the LED data pin and sets the LED count to 27.

2. ESP32 → OLED Display

The SSD1306 OLED communicates with the ESP32 using I2C.

1. OLED VCC → ESP32 power
2. OLED GND → ESP32 GND
3. OLED SDA → ESP32 GPIO 21
4. OLED SCL → ESP32 GPIO 22

The code specifically configures GPIO 21 for SDA and GPIO 22 for SCL.

3. Li-Po Battery → TP4056

The Li-Po battery is connected to the TP4056 charging module for charging and battery management.

The TP4056 allows the Li-Po battery to be charged through its charging input.

⚠️ Important: A TP4056 is a Li-Po charging module; it does not by itself convert the battery voltage into a regulated 5 V output. If the NeoPixels are being powered from a single-cell Li-Po, the actual power path should include the appropriate voltage regulation/boost circuitry.

4. Slide Switch

The slide switch is used as the main power control for the project.

This allows the complete system to be switched ON or OFF without disconnecting the battery.

🔗 Complete Connection Flow

🧠 How Everything Works Together

1. The battery provides portable power.
2. The TP4056 manages charging of the Li-Po battery.
3. The slide switch controls the system power.
4. The ESP32 acts as the central controller.
5. GPIO 5 sends data to the 27 NeoPixels.
6. GPIO 21 and 22 communicate with the OLED through I2C.
7. The OLED displays the time and current Moon phase.
8. The NeoPixels provide the Moon's illumination and animations.
9. Wi-Fi allows the ESP32's web interface to control the lighting.

The code confirms the hardware configuration of 27 LEDs on GPIO 5 and the OLED on SDA 21 / SCL 22.

Once the cement Moon has completely dried and all the electronics are ready, assemble everything inside the 3D-printed enclosure exactly as shown in the images.

1. Install the NeoPixel Strip:
2. Stick the 27-LED NeoPixel strip securely along the designated inner edge of the Moon tray/enclosure. Make sure the LEDs are evenly positioned and firmly attached.
3. Route the Connection Wire:
4. Pass the NeoPixel connection wire through the provided hole in the enclosure, as shown in the images. This keeps the wiring organized and allows the connection to reach the electronics inside.
5. Mount the ESP32:
6. Place the ESP32 in its designated position inside the enclosure and secure it firmly.
7. Secure the Components:
8. Use M2 screws and/or suitable glue to fix the electronic components in place. In this project, I used both M2 screws and glue, depending on the component and its mounting location.
9. Place the Battery:
10. Position the 500 mAh Li-Po battery securely inside the enclosure, keeping it away from sharp edges and the screws.
11. Install the OLED Display:
12. Fix the OLED module at the front opening of the enclosure so that the display is clearly visible from outside.
13. Install the Slide Switch:
14. Place the slide switch in its designated opening so it can be easily accessed from outside.
15. Arrange the Wiring:
16. Carefully route and organize all wires through the available channels and openings. Make sure the wires are not pinched or obstructed when the enclosure is assembled.
17. Follow the Reference Images:
18. Assemble all components in the same position, orientation, and arrangement shown in the images. Use the images as the main reference for the placement of the ESP32, battery, OLED, slide switch, NeoPixel strip, wiring, and other components.
19. Final Check:
20. Before closing the enclosure completely, power on the system and verify that the OLED, NeoPixel LEDs, ESP32, and controls are working correctly. Once everything is confirmed, secure the enclosure and complete the assembly.

After the cement Moon has completely dried, it is time to fix the Moon securely into the enclosure and then attach the enclosure to the base.

1. Fix the Moon Inside the Enclosure:
2. Carefully place the dried Moon into its designated position inside the Moon enclosure.
3. Apply Super Glue:
4. Apply super glue to the contact points where the Moon needs to be fixed, particularly around the area where the LED strip is attached.
5. Be Patient While Fixing:
6. The cement Moon is quite heavy, so take your time and be patient while the glue sets. Hold the Moon firmly in position and allow the adhesive to bond properly before moving it.
7. Check the Alignment:
8. Once the Moon is fixed, make sure it is properly aligned and securely held in the enclosure. Also check that the LED strip and its wiring remain in their correct positions.
9. Fix the Moon Enclosure to the Base:
10. After the Moon is securely fixed inside the enclosure, attach the Moon enclosure to the 3D-printed base. Align it properly with the base and secure it firmly.
11. Final Inspection:
12. Check the complete assembly to ensure the Moon is stable, the enclosure is securely attached to the base, and nothing moves or comes loose when the project is handled.

Once LUNARA is fully assembled, follow these steps to use and interact with the device.

1. Turn ON the Device:
2. Slide the power switch to the ON position. The ESP32 will start the system.
3. Startup Display:
4. For the first 8 seconds, the OLED displays the IP address of the device. At the same time, the 27 NeoPixel LEDs automatically turn on with a warm white Moonlight.
5. Moon Information Display:
6. After 8 seconds, the OLED switches to display the current time and Moon phase, along with the corresponding Moon-phase graphic.
7. Access the Web Server:
8. Connect your phone, laptop, or computer to the same Wi-Fi network as LUNARA. Open a web browser and enter the IP address shown on the OLED.
9. Control the Moonlight:
10. The web server provides an interactive control panel where you can control:
11. Different Moonlight shades
12. Brightness level
13. LED animations
14. Individual LED colors
15. Control All 27 LEDs Individually:
16. Each of the 27 NeoPixel LEDs can be controlled separately, allowing you to create your own custom Moonlight patterns and color combinations.
17. Experiment with Different Effects:
18. Try different shades, brightness levels, and animations to create different appearances for LUNARA and give the cement Moon a dynamic glowing effect.

LUNARA is more than just a decorative Moon lamp. It combines handcrafted cement art, 3D printing, electronics, programming, IoT, and astronomy into one interactive project.

The project shows how an ordinary material like cement can be transformed into something dynamic and expressive through technology. The Moon can change its appearance through programmable lighting, while the ESP32 keeps track of the time and lunar phase.

Most importantly, LUNARA represents the idea that every phase has its own beauty. Just like the Moon, we do not have to shine at the same intensity all the time. Change is a natural part of the journey.

“The Moon is the first milestone on the road to the stars.” — Arthur C. Clarke
