Technology & Design Key Stage 3 A Suggested Year 9-10 Project Design Aroma Fan Electronic Systems RA Moffatt WELB RA Moffatt WELB.
Aroma Fan Learning Opportunities: An introduction to the Potential Divider using a thermistor as a temperature sensor; To develop design and manufacturing skills and Techniques; To develop understanding of electronic systems design. Activity Description: Theory: The study of potential dividers / transistors / thermistor / capacitors. Manufacture: To manufacture the box from given dimensions; Applied Design: to design the top for the Aroma Fan container. Electronics
Aroma Fan • Design Opportunities: • Show using concept sketches three alternative designs • for an attractive box top • Explain using graphics how the platform for the fan is held in place? • c) Draw the electronic circuit for this project in Live Wire and explain • how it works? • Explain how the electronics circuit works • Show using scrap sketches how the solar motor and battery are to be secured? • Name suitable materials for the box sides and base? • State a suitable protective finish for this project? Electronics
Concept Sketches The problem is to design a means of holding petals that are used to absorb the aroma oils
