Rocket Acoustics Signature Logger Kit with Arduino Mega + LED
Rocket Acoustics Signature Logger Kit with Arduino Mega — Capture and Analyse Motor Sound at 44kHz
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Understand the sonic fingerprint of your rocket motor by capturing and analysing its acoustic signature during static fire tests. This advanced kit uses the MAX9814 microphone amplifier to sample sound at 44kHz, performing real-time FFT on the Arduino Mega, and logging timestamped data to an SD card with RTC for precise spectral analysis. Ideal for aerospace engineering students, rocketry teams, and hardware hackathon participants.
What You'll Build
A portable, battery-powered logger that records high-fidelity audio during engine firings, displays the frequency spectrum on an OLED, and stores the complete acoustic profile for further study on a PC. You’ll have a tool to compare motor types, nozzle configurations, or propellant batches with repeatable, data-backed insights.
What You'll Learn
- High-speed analog sampling with the MAX9814 at 44kHz
- Real-time FFT implementation on the Arduino Mega
- SD card data logging with timestamped records via the DS3231 RTC
- OLED display integration for live spectral visualisation
- Soldering and PCB prototyping for robust, field-ready electronics

Who This Kit Is For
This advanced build is tailored for B.Tech students (Aerospace, ECE, EEE) working on rocketry or acoustic signal processing projects. It’s a strong fit for Smart India Hackathon hardware challenges, Spaceport India Cup teams, and final-year capstone projects at IITs, NITs, VIT, or BITS Pilani. Also suitable for ATL tinkering lab mentors guiding advanced school students (Class 12) and hobby rocketeers ready to move beyond basics.
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, we'll replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on your kit to access the AI build companion, which offers step-by-step troubleshooting. You can also message us on WhatsApp — our engineers will guide you directly.
Do I need prior soldering experience?
Some soldering is required to assemble the two prototype boards. The included soldering iron and our build companion video tutorials will walk you through each joint, making it manageable even for relative beginners.
Can this logger be used for other acoustic measurements like engine knock or vibration?
While optimised for rocket motor acoustics, the 44kHz sampling and FFT pipeline can analyse other sounds. With minor code tweaks, you can adapt it for engine diagnostics, vibration signatures, or environmental noise monitoring.
How do I view and analyse the FFT data after the test?
The OLED shows live frequency peaks, but all raw FFT output is saved as timestamped CSV files on the MicroSD card. Simply transfer the card to a PC and use Python, MATLAB, or Excel to plot and compare acoustic signatures.
MAX9814 samples sound during static motor firing at 44kHz. FFT characterises acoustic signature of motor.
