Rocket Acoustics Signature Logger Variant 24 Kit with Arduino Mega + LED
Rocket Acoustics Signature Logger Kit with Arduino Mega — Characterise Your Motor's Acoustic Fingerprint
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
When you fire a solid rocket motor, its unique acoustic signature reveals essential performance data—combustion stability, thrust oscillations, and potential anomalies. This kit lets you capture that signature at 44 kHz using the MAX9814 microphone amplifier, perform real‑time Fast Fourier Transforms on the Arduino Mega, and log every frequency spectrum with a precision timestamp on a microSD card. It’s the same approach used by advanced rocketry clubs and B.Tech capstone teams for motor characterisation and quality control.
What You'll Build
You’ll assemble a portable, battery‑powered acoustic logger that samples high‑fidelity sound through the MAX9814, runs an FFT algorithm on the Arduino Mega to extract frequency components, displays the live spectrum on a 0.96‑inch OLED, and writes time‑stamped CSV files to the microSD module using the DS3231 real‑time clock. The result is a field‑ready instrument that can log minutes of motor burn data, ready for post‑test analysis in MATLAB, Python, or any spreadsheet tool.
What You'll Learn
- 44 kHz audio sampling with the Arduino Mega’s ADC and MAX9814 preamplifier
- Implementing a real‑time FFT for frequency‑domain characterisation of acoustic signals
- Designing a timestamped data logging system using an SD card and DS3231 RTC
- Soldering and assembling a compact prototyping board into a rugged, field‑deployable unit

Who This Kit Is For
This kit is built for B.Tech ECE and EEE students working on final‑year projects in embedded signal processing, for rocketry teams at IITs, NITs, and BITS Pilani conducting static motor tests, and for Smart India Hackathon participants designing real‑time acoustic monitoring solutions. It also fits ATL Tinkering Lab mentors guiding advanced student projects in rocketry instrumentation and data acquisition.
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?
The AI companion on the QR code gives step‑by‑step debugging, and our WhatsApp support responds within hours—you’ll never be blocked.
Can this logger be used with different rocket motors?
Absolutely, the FFT parameters and logging intervals are configurable; you can compare acoustic signatures across any solid motor size.
Do I need an oscilloscope to verify the signal?
No—the OLED displays the waveform and real‑time spectrum, so you can validate the mic signal directly on the device.
What programming skills are required?
Basic familiarity with the Arduino IDE is enough. The AI companion provides complete code, walks you through FFT libraries, and explains every line.
MAX9814 samples sound during static motor firing at 44kHz. FFT characterises acoustic signature of motor.
