🔧 DIY Flynn-vention Guide
Turn Science Fiction into Hands-On Discovery!
The DIY Flynn-vention Guide is where readers become inventors! Inspired by the real science-based gadgets Kai builds in the Kai Flynn Adventure Series Books, this section builds unique engagement and gives kids, classrooms, and educators the chance to build their own working inventions using beginner-friendly electronics kits, coding basics, and household materials.
Each Flynn-vention is based on a real STEM concept from the book — like motion-sensing alarms, robotics, or environmental sensors — and includes:
✅ Step-by-step instructions
✅ Kid-friendly analogies that explain science in a fun way
✅ Links to STEM kits and parts
Whether you’re a parent, teacher, or a curious kid, these inventions spark creativity, build STEM confidence, and bring the Kai Flynn universe to life — one gadget at a time.
🧪 Build. Learn. Explore. Start your Flynn-vention today!

Mystery At The San Diego Zoo
Chapter 11: DIY Flynn-vention Guide Book One
In Book One, Kai uses his quick-thinking STEM skills to catch a mysterious saboteur at the San Diego Zoo — and now it’s your turn!
Kids will build a motion-sensing alarm system, just like Kai’s, using real-world electronics from the Elegoo Super Starter Kit (or similar beginner Arduino kit). With simple instructions and fun analogies, readers learn how to:
🧠 Detect movement using a PIR motion sensor
🔊 Trigger a buzzer when someone walks by (like Kai’s squeaky sneakers!)
💡 Code the invention using beginner-friendly Arduino software
🔧 Connect wires and sensors using a breadboard and jumper cables
This DIY project is perfect for young inventors who want to build something real, fun, and functional. It’s spy gear, STEM-style!
📦 All parts are linked so kids can easily follow along and invent at home.
🔍 Science Concepts Covered:
• Motion detection
• Electrical circuits
• Coding logic (IF-THEN)
• Sensors and outputs
📣 Team Flynn never gives up — and now you can invent like Kai too!
