Rocket Motor Casing Pressure Test Rig Variant 29 Kit with Arduino Mega — an expert-level kit for adults.
Arduino Mega 4-Port Hydrostatic Pressure Test Rig — Safety-Interlocked Rocket Casing Validation
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 1-5 days.
This kit turns raw components into a bench-top hydrostatic test station that validates the structural integrity of rocket motor casings before live firing. Four MPX5700 pressure transducers monitor casing ports simultaneously while an Arduino Mega runs a hardwired safety interlock—cutting off the pump the instant any pressure channel exceeds its threshold. The result is a repeatable, data-logged, safety-first protocol used by university rocket teams and serious hobbyists.
What You'll Build
A DIN-rail enclosed pressure data acquisition system. You will connect four analog sensors to the Mega’s ADC, calibrate them for 0–700 kPa, and write a firmware sketch that reads all channels, logs time-stamped data to a microSD card, and renders live pressure curves on a 2.4-inch TFT display. A 4-channel relay module, driven by redundant safety logic with diodes, acts as a hard cut-off for the external pump, ensuring that a single sensor fault can still trigger an immediate shutdown.
What You'll Learn
- Configuring MPX5700 analog pressure transducers for precise hydrostatic range and linearity
- Implementing a multi-channel redundant safety interlock using relays, diodes, and polling loops
- Timing sensor reads with a DS3231 RTC and storing structured logs on a microSD using SPI
- Soldering noise-resistant analog front-ends on prototyping boards and housing them in a DIN rail enclosure

Who This Kit Is For
Aerospace and mechanical B.Tech students building Smart India Hackathon pressure-testing modules, propulsion teams at IITs, NITs, or BITS Pilani qualifying student-built casings, and experienced amateur rocketeers who need a repeatable hydrostatic protocol rather than ad-hoc plumbing. Prior Arduino coding and basic soldering are assumed.
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?
Scan the QR code to open a chat with the project-specific AI companion, which knows every component, connection, and calibration step. Human engineer support is also available via WhatsApp within 24 hours.
Can I test real rocket motor casings with water?
Yes, the kit is designed for hydrostatic (water) proof-testing of metal or composite casings up to 700 kPa. Always follow your local safety norms and use proper shielding during tests.
What happens if a sensor fails during a test?
The safety interlock logic continuously compares all four channels. If any reading exceeds the programmed limit or if a sensor output becomes erratic, the relay cuts pump power within milliseconds, preventing over-pressurisation.
Do I need prior experience with Arduino Mega and SPI?
This is an advanced kit. You should be comfortable writing Arduino sketches, wiring SPI displays and SD modules, and soldering through-hole components. The AI companion provides complete code and schematics as a reference.
