Parachute Ejection Charge Pyro Tester Kit with Arduino Mega + Relay
Arduino Mega Parachute Ejection Charge Pyro Tester Kit — Safe, Repeatable Testing for Rocket Recovery Systems
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit gives you a standalone pyro circuit tester that simulates an ejection charge ignition using capacitor discharge, complete with continuity check, arming switch, and fire button, so you can validate your recovery system on the ground before launch. Whether you're prepping for a student rocketry competition or testing a dual-deployment system for Level 2 certification, this tool brings fail-safe confidence. Every connection, every relay closure, and every capacitor charge cycle has been pre-validated for mission-critical reliability.
What You'll Build
You'll build a bench-top instrument that charges two high-capacity capacitors to a precise voltage, confirms continuity across an igniter with visual and audible feedback, and fires a test e-match via a relay-controlled discharge. The 16x2 LCD displays real-time capacitor voltage, arm state, and continuity status. The final assembly fits inside a DIN rail enclosure, ready to sit on your workshop bench between flights.
What You'll Learn
- Designing isolated high-current capacitor discharge circuits for pyro applications
- Interfacing a 4x4 keypad for arm codes and mode selection
- Reading current and voltage with the INA219 sensor to monitor charge state
- Implementing hardware and software safety interlocks to prevent accidental firing

Who This Kit Is For
This kit is built for India’s high-power rocketry community — whether you're an aerospace engineering student at IIT, NIT, or VIT designing a recovery system for Smart India Hackathon, a researcher at DRDO testing ejection mechanisms, or a Level 3 certified amateur rocketeer preparing for your next launch at the Spaceport in Sriharikota. It’s also ideal for ATL Tinkering Lab mentors teaching advanced electronics and safety protocols.
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 QR code on the box to access your AI build companion trained on this exact pyro tester, or message us on WhatsApp for human help from a builder who has built this kit.
Can this tester fire a real ejection charge?
Yes, the relay output is designed to interface with standard e-matches or igniters. Always follow safety protocols: arm the system only when ready to fire, keep clear of the charge, and test with a dummy load first.
What safety features does this kit include?
The system uses a physical arm switch, a coded keypad sequence to enable firing, and the relay isolates the high-current capacitor discharge from the Arduino. The LCD and buzzer provide constant status feedback.
Is this kit suitable for classroom or workshop use?
Absolutely — the DIN rail enclosure and clear labelling make it safe for supervised use in B.Tech labs or rocketry workshops. Each build teaches circuit design, programming, and safety protocols crucial for any pyrotechnic system.
