   Problem:

Smulski Enterprises has commissioned the BFA Engineering department to provide prototype examples of swag they can sell on the open market.  The product must be made from 1/4" finished plywood and be reproducible.

 key chain's

 Refrigerator magnet

 Coasters 

ACTION STEPS

You will choose 4 pictures that must be black and white.  

You will need to save these pictures to your computer.  Remember where you save the pics.

Bring Image into AI

Live trace the image

Ungroup the image

Select the direct selection tool

delete the outside shape and any white background image

Check image for any tails, spots or hangers and delete them

Save image as an SVG

Bring image into Glowforge

Parameters

#1

1)Key chain must be have an outside diameter of 2" or less

Must have a 1/8" hole near the edge to accept a key chain ring.

#2

1) Choose either of the 2 next projects

2) There must be Text on the Product that is created by the designer

3) There must be a cut out other than a perimeter shape, this can be either the text or part of the logo

ASSIGNMENT 

As we discuss the realizations, Engineers and Scientists may have not considered the impacts and  Downstream affects of critical decisions, consider the actions which have led to the extreme pollution across the world, answer the following questions.  

Post your answers in the comment section to below questions. 

In your observations of the videos identify obstacles which would hold back or hinder the collection process of the ocean clean up and the interceptors 

Take a stance on whether these types of collection devices are serving the symptom or the cause in the fight against pollution and environmental inequality for some across the world?
