Overview - Project Outline - Research & Literature Review - Experiments - Prototyping Process 5

Project Outline 6

Main Objective Create a waterfall display with oil as the medium 7

Secondary Objectives Using the prototype as a proof-of-concept: a. Improve the maximum display quality of the prototype b. Make the prototype more aesthetically pleasing 8

Experiments 14

Water, Oil & Food Colouring Water, oil and food colouring do not mix together Water droplets with food colouring Food colouring droplets 15

Water, Oil & Food Colouring - Dropped food colouring through oil - No stained oil - Dropped water with food colouring through oil - No stained oil - Drops merged over time - Conclusion: Food colouring is not oil soluble 16

Speed of Water through Baby Oil - Dropped coloured water through baby oil - Varying heights - Speed of water through baby oil is roughly 3.1 cm/s 17

Speed of Water through Baby Oil Speed = Reciprocal of Gradient = 3.1 cm/s 18

Prototyping Process 19

The previous prototype... 20

Problems of old prototype 1. Aesthetically displeasing 2. Water leaked often from the jar 3. Low display quality 21

Improving... 22

Improving... Water leaked often from the jar - Better sealage - Replaced containers 23

Improving... Low display quality - Oil instead of air - Slows water down 24

Slave Master Serial Communication Valves 25

One-Way Serial Communication Master: Open Valve at Port 08 Credit to: Sparkfun 26

Programming ◆ Instructions - cycle through each valve from the first to the last at a set interval (proof-of- concept) ◆ Patterns can be added through the code for a performance 27

Circuitry 28

Areas for Further Research ◆ Using a backlit board ◆ Additive Colour Theory ◆ Higher control over aesthetic design ◆ Change colours 29

Our final prototype! 30
