Thrust Vector Control (TVC) lets rockets steer by tilting their engines, changing the direction of thrust mid-flight. Used by SpaceX’s Falcon 9 and Starship, TVC replaces fins in space, guiding rockets with precision. Through dual-axis gimbals, simple trigonometry, and real-time control, rockets stay stable and on course. From large boosters to student-built models, TVC is the key to modern rocket control and reusable spaceflight.

Arduino is a fun and beginner-friendly way to dive into the world of electronics and coding. It’s a small, affordable device that you can program to perform various cool functions, such as blinking lights, sensing motion, or even building your robot.

If you've ever found yourself squinting at color bands on tiny cylinders while soldering a circuit board, you're not alone. Understanding resistors—especially metal film resistors—is a rite of passage for electronics hobbyists and professionals alike.
