Give instructor top 3 project choice list

 * Coanda
 * Bernoulli
 * Boat

Write problem statement

 * How to create some kind of rubberband gun that is extremely accurate and efficient when it comes to firing and reloading.

Assign Task1

 * Create basic designs for potential gun models whether it is a gattling/pistol.
 * Research already made rubberband gun models and upload them on wiki for reference.
 * Make a list of what type of material may be used for a gun (ex. wood, legos)

Compare actual work done to Task1
Created basic designs on google sketch up Started building pistol

Week1 Narrative

 * This week, two models were drawn up using google sketch up. Throughout the week, the group members and I started building two guns. One was the pistol which was build upon the sketch up. The gattling gun however was ruled out since it involves the use of engines in order to rotate. The team was close to deciding on using an old gattling gun model saved in the enes folder in the lab however decided to start from scratch.
 * The image above symbolizes the typical lego blocks that were used to build the bases of our weapons.

Assign Task2

 * Start creating a more efficient trigger system for the pistol.
 * Research rubber band pistol models in order to build on ideas to implement on our guns.

Compare actual work done to Task2
This week the work that was done on the gun included:
 * Finding trigger system animations that allowed us to study how we can implement it on our guns.
 * Started creating a simple sketch-up of our gun which will allow us to edit our gun before implementing it on our system
 * Help add an additional trigger system on our main gun to fire multiple rubber bands
 * Presented our product to the class in order to get feedback and comments which will give us additional ideas in improving our gun.

Assign Task3

 * Create separate pieces for a specific trigger system I want to try on our gun(s)
 * Try to create an even more detailed sketch-up

Week3 Activities
Rationalize differences
 * This week, more work was done on google sketchup as part of the trigger system was created.
 * A new and more efficient rubberband gun was made from legos
 * Additional trigger systems were analyzed

Week3 Narrative
Learning curve throughout the sketch:
 * The basic shape of trigger was made by drawing a square.. the cube was created by using the 3-D tool
 * The square was pulled
 * Encountered problem when I wanted a hole in the square
 * Tried using an eraser however it didn't work
 * Created an inner square; and then pushed that part in
 * This allows the square to be inserted into the gun once it is printed
 * Creating the triangles on the side.
 * Used the pencil tool in order to create the triangles.
 * Placed lines on the sides of the cube and then created the final side of the triangle. The triangle lays outside the base of the cube as shown in the picture.
 * Encountered a problem when I wanted to connect the triangle at the top. This happened when drawing the second triangle on the other side..Once the final line was drawn (the one that lays outside the cube).. sketchup automatically connected that line with the edge of the first triangle.
 * First I tried drawing the final line again however it still automatically connected the lines.
 * Thought that if I rotated the screen or tilted it, then it would be easier to draw the final line.
 * Used the rotation tool and then drew the second triangle. Panned around a bit and made sure everything fits and is on the same axis (even though i rotated my screen)
 * Sketch up of trigger
 * Sketch up of sling rubber band gun

Assign Task4

 * Try to print out the part that was done on sketchup
 * Keep improving the design and reloading system in the gun to create the most efficient gun
 * Keep analyzing different trigger systems and see if they can be implemented on our gun.

Compare actual work done to Task4

 * My partner created a gun with a trigger system out of gears
 * Helped improve the design of the trigger by extending it and making it look more like a gun.
 * Looked back at the gattling design.. played with it some more
 * Searched for motors that can eventually spin our gun in the future.

Week4 Narrative
DC motors
 * Eventually use one of these which supply enough power and are cheap enough to buy
 * Additionally, I tried working on the design of the gattling gun since the idea of the project was brought up again.I encountered several problems on sketch up. For instance, creating a stand for the cylindrical gattling gun to be placed. I tried using the pull button from the bottome of the cylinder however the software stated that curved objects may not be pushed and pulled. The motor will be placed in the back and is labeled by the black square in the sketch. The handle of the gattling gun could not be drawn either since a circle with a small radius was not allowed to be drawn.
