Give instructor top 3 project choice list

 * Rubberband Gun
 * Robot arms
 * Strandbeest

Write problem statement
From our previous works, how are we going to build more advanced guns that can fire sequentially?

Assign Task1

 * Get ready to order/bring in necessary pieces for further contructions
 * Research further on the sequential firing rubberband guns
 * Research if there are another pieces we can use other than Legos and rubberbands. Example: metal spring, wires, small wood or plastic pieces.
 * Find a various techniques that the other use on their Gatling guns and sequential firing guns [Gatling gun]

Compare actual work done to Task1

 * I brought my pieces of the LEGOs for the construction of the gatling gun and sequential firing guns.
 * Did a long hour research on the guns that were previously attempted by HCC students and the Youtube videos of rubberband guns.
 * Successfully came up with the LEGO design and built the working prototype of our gatling gun in 1 week period
 * Tried to further expand on the prototype rather than calling it an end for the week 1.
 * Improved on the previous gun while also studying its trigger system for future products.

Week1 Narrative
[My first gatling gun:testing]
 * With the new gatling gun prototype built, I took many pictures and some videos.

Assign Task2

 * Once again bring my own pieces for further constructions
 * Present to the class our successful gatling gun prototype
 * improve the prototype
 * Build upon the prototype and plan to create new gatling gun that has different trigger system

Compare actual work done to Task2

 * Brought my own pieces for further construction
 * Presented to the class
 * The gatling gun is now have dual barrel
 * Tested both barrel and found perfectly functioning

Week2 Narrative

 * This week with only 1 class time to work on the project, I managed to build fully functioning double barrel gatling gun. All needs now is main base to hold the body of the guns and the engines.
 * Here is the test on the double barrel gatling gun [Testing on Gatling gun]

Assign Task3

 * Once the sight alignment testing is done, it will be applied on the gatling gun as well
 * Construct the main base of the gatling gun
 * Apply the engines on the gatling gun

Compare actual work done to Task3

 * Improved the gatling gun so that the double barrels move together but opposite directions
 * Presented to the class about our project's progress
 * Selected and ordered the generators for the motors for the gatling gun
 * Debated about the trigger system: String or gears?

Week3 Narrative

 * The great advantage of my design is that the whole gatling gun can be easily modified. The pieces that I placed can be easily removed and can put better or improved parts into the structure. And the new pieces can be fitted into the empty spots without huge change in structures.
 * The multiple videos and pictures are taken to document the improvements and changes on our projects:
 * [The very frist prototype of the complex gear]
 * [The expanded complex gear for gatling gun]
 * [The testing of the gatling gun with the complex gears: Synchronized but only rotate in one direction]
 * [Fixed rotation of the gatling gun: Rotates in opposite direction (inward)]

Assign Task4

 * Push to finalize the project
 * Decide what the trigger will be for the gatling gun
 * Test the trigger system and the motors+engines
 * Check for repeatability of this project

Compare actual work done to Task4

 * Created the string winders. They wind up the string that are winded on each slots of the barrels and as they wind up the string, the rubberband is released/fired.
 * Tested the string winders for reliability.
 * Synchronized the string winders so that they allow the rubberbands on each slots to be released at the same time

Week4 Narrative

 * I was able to create the trigger system for the rubberband gatling gun. The string winders proves effective but still need to be improved for durability (Able to withstand the tension of the rubberbands and pull out the string to fire them) and reliability (Do they effectivily and successfully release the rubberbands)
 * [Fire testing] for the gatling gun with the string winder/trigger
 * There were some [issues] and [problems] during tests

 * Take the final before due date/time
