Two pages of notes intended for Level 3 learners studying Electronics A-Level or BTEC Engineering.

An extensive flash card activity for electrical equipment and accessories. Set of 40 flashcards to cut out. A 40 page powerpoint gives the name of the equipment and students to place or stick appropriate images over the six blank spaces on worksheet. Good for starters/plenary, different cards can be selected depending on the content of the lesson.

A complete design and make project based on the design and construction of a torch using QTC pills as switches, two LEDS and a thyristor. The design and building of the project is divided into eight stages which can form the basis of individual sessions. The project includes the following detailed powerpoints: Introduction - 10 pages setting out the design brief and providing detailed 3D renderings of an examplar product Prototyping - 6 pages explaining the importance of prototyping Making the case - 11 pages demonstrating how a 2D package and laser cutter are used to produce torch body by laminating acrylic QTC Circuit: 13 pages describing how QTC works and how it is applied to the project Building the circuit - 2 pages showing PCB layout, component list and PCB design which can be used to manufacture the PCB Making the battery holder - 5 pages showing how copper strip is moulded to form a battery holder Laminating: 5 pages briefly setting out how acrylic can be laminated to make 3D models Finishing Techniques - 11 pages showing how files, wet and dry and buffing machines are used
