Aroma FanDesign Opportunities:

a) Show using concept sketches three alternative designs for an attractive box top

b) 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?

d) Explain how the electronics circuit works

e) Show using scrap sketches how the solar motor and battery are to be secured?

f) Name suitable materials for the box sides and base?

g) State a suitable protective finish for this project?
