Technology and Design study guides

A deep-dive CCEA A-Level Technology and Design guide to the A2 Electronic and Microelectronic Control Systems option. Covers sequential logic and counters, op-amps in control (summing, difference, follower), analogue-to-digital conversion and resolution, the microcontroller (PIC), flowcharts and programming constructs, and open- and closed-loop control with PID.

A deep-dive CCEA A-Level Technology and Design guide to the A2 Mechanical and Pneumatic Control Systems option. Covers structures and loading (ties, struts, triangulation, beams), stress, strain and the Young modulus with factor of safety, work, power, torque and efficiency, advanced mechanisms, and pneumatic control circuits with logic valves, time delay and sequencing.

A CCEA A-Level Technology and Design guide to the A2 2 Product/System Design and Manufacture coursework: the major internally assessed design-and-make project, how it extends the AS task in independence, technical depth and quality, the role of quality control and health and safety, and how it is assessed.

A deep-dive CCEA A-Level Technology and Design guide to the AS 1 Design and Manufacture core. Covers the iterative design process, specifications, research and ergonomics, communication of proposals, classification and properties of materials, composites and smart materials, manufacturing processes and scale of production, quality control, evaluation and sustainability.

A deep-dive CCEA A-Level Technology and Design guide to the AS Electronic and Microelectronic Systems option. Covers the input-process-output systems approach, input sensors and the potential divider, the transistor and MOSFET as switches, op-amp comparators and amplifiers, logic gates and Boolean algebra, the 555 timer in monostable and astable modes, and output transducer drivers.

A deep-dive CCEA A-Level Technology and Design guide to the AS Mechanical and Pneumatic Systems option. Covers the four types of motion and mechanisms, levers and the principle of moments, gears and gear ratios, belt, pulley and chain drives, cams and followers, and pneumatic cylinders, valves and thrust.

A CCEA A-Level Technology and Design guide to the AS 2 Product Development coursework: the internally assessed design-and-make task, what the design folder and prototype must evidence across the design process, and how the work is marked against CCEA's criteria and externally moderated.
