Parachute Ejection Charge Pyro Tester Variant 30 Kit with Arduino Mega
Advanced Parachute Ejection Charge Pyro Tester with Arduino Mega – Validate Recovery Systems with Precision
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
For rocketry teams and aerospace hobbyists, a failed parachute ejection can mean a total mission loss. This kit lets you build a bench-top pyro tester that replicates the exact firing sequence used in high-power recovery systems. You'll construct a capacitor discharge circuit with continuity check, a physical arm switch, and a fire button — all monitored by an INA219 current sensor and displayed on a 16x2 LCD. Before you ever load a real e-match, you'll know your circuit delivers the right current pulse.
What You'll Build
You'll assemble a DIN-rail mounted test instrument that charges two 4700µF 35V capacitors, verifies igniter continuity via a dedicated sensing loop, arms the system through a keypad-acknowledged arm switch, and fires a solid-state relay on command. The LCD shows real-time voltage, current, and system state. This is not a toy — it's a ground-test version of the redundancy circuit used in experimental sounding rockets and CubeSat recovery systems.
What You'll Learn
- Design and safe handling of capacitor discharge pyro firing circuits
- INA219-based high-side current and voltage monitoring for transient pulses
- State-machine logic on Arduino Mega for arm-fire-abort sequences
- Integrating a 4x4 keypad for secure arming and test mode selection

Who This Kit Is For
Built for rocketry teams participating in university competitions and research groups needing reliable ground support equipment. Ideal for B.Tech ECE/EEE students working on payload recovery systems, participants in Smart India Hackathon aerospace challenges, and Tinkering Lab mentors overseeing advanced projects. If you've already flown mid-power rockets and need to validate dual-deployment electronics before a level-3 certification attempt, this kit delivers the precision you require.
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 the AI companion for immediate troubleshooting. If you need human help, our WhatsApp support responds within hours for advanced rocketry projects.
Does this kit include e-matches or pyrotechnic material?
No, for safety and legal compliance, the kit only includes the electronic tester. You supply your own certified igniters and pyrogen.
Can I adapt this to fire a real ejection charge later?
The circuit design is identical to flight hardware but lacks the flight computer. Use the knowledge gained to integrate your own altimeter and deployment logic.
What safety features are built into the design?
The arm switch, keypad arming code, and continuity check create a three-layer safety sequence before the relay can fire, as described in the build guide.
