Measurements (Also linked with 'Environment')

Need to be precise to stop wastage

LED light used to symbolise current flowing through curcuit if switch is on or off. This is used to stop battery wastage, as battery replacement is costly.

Don't waste wire with too much. Measure correctly. Also with soldering - don't use too much tin. This will waste energy (power outlet) & Materials

Components

Switch

LED light for on/off

Jack Wire

PCB (Printed Circuit Board)

Screws (Need Drill (Need power outlet)) (To secure PCB to wood)

Soldering (With Components & PCB)

Materials

Tools

Possible Dangers

Electric Drills

Saw

Solution = Care

Other

Vinyl (Need Vinyl Cutter)

Used to print words, images, symbols, e.c.t onto most materials.

Metals

Wire mesh for speaker cover

Thermoplastics

Acrylics

Used for protection against damage to speaker

Negative

Extremely Brittle

Easy To mold

Colour variation - wide

Electronics (see electronics section)

Softwood

Pine

Uses electric and normal saw for cutting & electric drill for drilling

Negatives

Dents and Scratches Easily

Hard To shape

Positives

Easy To customize

Strong join when glueing

Easy To work With

Drilling

Cheap

Environment

Volume limit 75db

Noise pollution unwanted

Wider World

Efficiency vital

Less waste = less demand for materials = less factory fumes or more trees

LED light

Symbolises power, good for environment - battery doesn't waste and less batterys need to be produced

Rechargable batterys - reduces cost also

Safe

No debris

Clean

Customer

Can be gift or product

Requirements

MONEY for purchase

needs an output on their phone/ iPod

Citizen

Portable optional - can be non portable

Athlete

Needs to be light and portable

Any age

Safety

Product

No easy access to electronics

No open wires

No sharp edges

Workshop

Danger hazards

Debris across floor

Awareness

Machinery

Proper conduct around machines

Caution

Tight seal around PCB and battery for water resistant guarantee

Need To be careful with tools that could cause danger (Already Linked)

Joining Methods

Mesh

Glue

Vinyls

Subtopic

Has it's own self adhesive
