Spin-Stabilised Rocket Roll Rate Logger Kit with Arduino Nano + MPU6050
Verify Rocket Spin Stabilisation – Arduino Nano & MPU6050 Roll Rate Logger Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
A rocket spins to stabilise its trajectory, but how do you prove your fin design generated the right roll rate? This kit equips you with a self-contained data logger that rides inside the payload bay, sampling the MPU6050 gyro’s Z‑axis at high speed and writing every raw angular velocity point to microSD. After recovery, you open the CSV, plot spin rate over time, and see exactly when the motor burned out, when roll peaked, and whether the spin stayed within the safe zone.
What You'll Build
A compact, battery-powered flight recorder that captures gyroscope data at 100 Hz onto a microSD card, timestamped by a DS3231 real-time clock. The whole assembly fits on a prototyping board, wired for vibration resistance and powered by a small LiPo cell with onboard charging. Once the rocket lands, you remove the microSD, plug it into a laptop, and immediately graph roll rate in Excel, Python, or MATLAB to validate your spin stabilisation model.
What You'll Learn
- Interfacing an MPU6050 gyroscope via I2C and extracting Z‑axis angular velocity at a fixed sampling rate
- Storing high‑frequency sensor data on a microSD card over SPI with minimal jitter
- Timestamping each measurement with a DS3231 real-time clock to correlate flight phases with motor events
- Soldering an Arduino Nano and modules on a prototyping board for reliable connections under launch vibrations

Who This Kit Is For
Engineered for B.Tech ECE, EEE, and aerospace engineering students building sub‑scale rockets for competitions like Smart India Hackathon or inter‑college rocketry challenges. Equally suited for rocketry clubs at IIT, NIT, VIT, and BITS Pilani that need a repeatable, flight‑tested spin logger. Advanced CBSE Class 12 students with soldering and Arduino experience can also use it for science fair projects involving real‑world flight dynamics.
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 the QR code or message us on WhatsApp; you’ll receive specific debugging steps for the roll rate logger, including wiring checks and code verification.
Can I use this logger with a solid rocket motor vibration?
Yes. The prototyping board layout includes solder pads for securing components, and the AI guide shows you how to strain‑relief wires and encapsulate the MPU6050 to withstand high‑g launches.
Does the kit include a microSD card?
No, you supply your own microSD card (FAT32 formatted, 8‑32 GB recommended). The module works with any standard card, and the AI companion details the correct formatting steps.
How do I power the logger during flight?
The TP4056 module charges the 500 mAh LiPo, which powers the Arduino Nano and sensors for over 30 minutes — more than enough for a full rocket flight and recovery.
MPU6050 gyro Z-axis logs roll rate during rocket flight. Post-flight analysis confirms spin stabilisation.
