QTC Torch Project

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
