Plan of Procedure:
1) The first segment of clear tubing will connect to my partner’s portion of the project, but more specifically the storage tank.
2) The other end of the first segment of clear tubing will connect to the input brass hose barb on full port ball valve
+ +
3) Another brass hose barb will screw into the discharge side of the full port ball valve
+
4) The second segment of clear tubing will be attached to the output brass hose barb on the full port ball valve
+ +
5) The other end of the second segment of clear tubing will be attached to the input brass hose barb on the regulator
+ +
6) The third segment of clear tubing will connect to the output brass hose barb on the other end of the regulator
+ +
7) The other end of the third segment of clear tubing will connect to input hose barb adapter
8) The hose barb adapter will have the pressure washer nozzle screwed into it (completing the nozzle apparatus)
+
9) The nozzle apparatus will be attached to the servo, via a metal bracket, and will serve as the method of aiming the nozzle
+ + +
10) The automotive choke cables will serve as initial controls for the servo
+
11) If the automotive choke cables do not function properly, then a wireless system and controller will be implemented instead

Weekly Update 1/12-1/15
1/12
Yesterday, I worked all period and for twenty minutes after school on my STEMM report for the science, technology, and math involved in my project. I handed it in at the end of the day.
1/15
I have readjusted my drawings and handed them in. I had to make changes after learning that my original concept was not entirely feasible (thanks to my new possible mentor contact at Granger).

Weekly Update 1/5-1/8
1/5
On suggestion from my instructors, I began to search through a Granger catalog. Through this catalog, I hope to find the parts I need for my design. Though, I see I have to adjust my drawings in accordance to the parts I find.

Yesterday, I visited Granger and met a possible new mentor contact. The chief engineer and salesman at Granger personally helped me for over an hour on my design. I purchased several new parts that will change my design. I must update my drawings.

Weekly Update 12/21-12/23
12/21
I have begun searching the internet for pieces that exactly fit the concepts I have devised. I hope to find the pieces that will assemble into my nozzle apparatus by (shortened) week's end.
12/23
All of the pieces the nozzle apparatus will be comprised of have been found. Unfortunately, certain dimensions are missing from their online descriptions. Over the break I will have to find out what those missing variables are.

Weekly Update 12/15-12/17
12/15
I have been in the process of completing my materials list and plan of procedure. I have also been working on my drawings. I will attempt to get as far as possible by the end of the week.
12/17
I have comprised a rough outline of my materials list and plan of procedure, and have completed all of my drawings, save the exploded view.

Weekly Update 12/8-12/11
12/8
Today, my partner and I went into the shop room to experiment with an air compression tank and nozzle to find out how much pressure is required to move each type of ball in the competition. Alas, due to a communication error, I did not bring in the necessary types of balls to test. However, I did have a tennis ball in my car and was able to use that as a substitution. By using this ball and my prowess in mathematics, I was able to calculate the necessary air pressure needed to use the other types of balls.
12/11
While I was out, my partner met with Ms. Green after she attended a meeting about the Technology Dare event. In this meeting, My partner was able to discern some new ideas of what works and what does not in the area of our project.Meanwhile, my partner and I went to the shop again to continue testing with the air compressor and nozzle, this time armed with the necessary balls to test with. The nozzle had an opening of about 1/8 inch to allow air through. With such a focused force, it only took 25 PSI to move the cueball. However, we removed the convergent nozzle so that there was an opening with a diameter of about 1/3 inch. Even after we ratcheted up the PSI to 70, we were unable to move the cueball. Initially, I had designed my nozzle to be 1-1/4” in diameter. However, now that we were able to test, it has become abundantly clear that this must be adjusted somewhat.

Weekly Update 11/27-12/1
11/27
My partner and I discovered several flaws in our design and must discuss what we can do to fix this dilemma. Also, I must find some other sources to get a good, low price for a hose.
12/1My partner and I discussed how we could properly attach my portion of the project to his in the most structurally sound way to hopefully yield better output and prevent loss of airflow. My bid sheet has also been completed.
