Core Skills Analysis
Science (Physics)
Brad examined the magnetic components inside joysticks and keyboards, identifying the types of magnets and how their fields interact with electronic circuits. He explained how magnetic flux influences the movement of sensors and the registration of button presses. By testing different magnets, Brad observed variations in signal strength, deepening his understanding of electromagnetism. This hands‑on work helped him grasp concepts such as magnetic polarity, attraction, and repulsion in a real‑world context.
Design & Technology
Brad evaluated how magnet placement affects the ergonomics and reliability of gaming controllers, sketching redesigns that could reduce latency and wear. He considered material properties, manufacturing constraints, and user comfort while proposing alternative magnet housings. By prototyping simple mock‑ups with 3‑D printed parts, Brad practiced iterative design and problem‑solving. This activity linked theoretical knowledge to tangible product development.
Computing
Brad investigated how the hardware signals from magnetic sensors are interpreted by a computer’s firmware, mapping the flow from analog magnetic changes to digital input codes. He documented the communication protocol between the joystick’s microcontroller and the gaming software. By comparing different controller models, Brad learned how firmware updates can calibrate magnetic sensitivity. This reinforced his grasp of hardware‑software integration.
Mathematics
Brad recorded the magnetic field strength readings for several magnets and plotted the data to see how distance affected signal output. He calculated percentages of error between expected and measured values and used simple linear regression to model the relationship. These calculations sharpened his data‑analysis and statistical reasoning skills. The activity demonstrated how mathematical models support engineering decisions.
Tips
1. Let Brad design a controlled experiment where he varies magnet size and material, recording response times to quantify performance gains. 2. Have him create a digital prototype using CAD software and simulate magnetic field interactions before building a physical model. 3. Organize a mini‑hackathon where Brad codes a simple game that visualizes real‑time input from his modified controller, reinforcing hardware‑software loops. 4. Encourage a reflective journal entry where he connects the physics of magnetism to broader gaming industry challenges.
