PROBLEMS, MATERIALS SHIFT AND DC MOTOR (Week 8)

Due to some problems regarding the main material which is the paintball gun, I had to go and look for other material that can be use as a projector that can project enough high air pressure to propel the shuttlecock.

The paintball came out with a problem that it is a fully manual triggered gun. This is a problem that I had failed to notice when I first purchased the gun. A suitable paintball gun that can be used is the fully automatic triggering which is known as the tactical paintball gun for professionals. Furthermore, the gun I purchased is a basic gun for beginner.

Another problem  is that the high pressured tank containing Hydrogen is empty. In order to refill the tank again I have to spend another few hundreds and because i cannot use the paintball gun, I have to really come out with another solution fast.

After doing another research and discussion made with friends and lecturers, the suggestion is to use a nail gun. It has the same concept of pneumatic which it can provide enough air pressure to propel the shuttlecock perfectly.

Due to shortage of budget and critical amount of time because of last minute problems, I decided to look for a second hand nail gun and a small air compressor to provide enough pressured air to the nail gun.

Another addition to my final year project (Badminton Trainer) is that i mounted a DC motor which is specifically used in car windshield wipers. It is mounted on the base of the badminton trainer along with the wheels. This is made so that the badminton trainer will do a rotation from left to right or right to left exactly about 90 degrees continuously until the power supply is turned off.

The picture is as shown as below.

STRUCTURE SKETCHING, LOGBOOK UPDATE (Week 7)

During this week, regardless that it is the mid term break for BMI. I have stayed in BMI doing the final year project research and buying materials that are needed for the project. I also have come out with a new structure for my project.

It is drawn this way because I want to send it to the welding shop so that I can come out with an exact and perfect and desired measurement of my final year project. Below is the drawings that I have done and sketched.

Also during this week, I have updated my logbook and inserting every single important details into my logbook just as I have updated my final year project blog. Because in the blog I cannot insert all of the materials and hard copy of my findings, I decided to insert them in my logbook.

EXTRA RESEARCH, HPA TANK PURCHASE (Week 6)

During this week. Regardless that I have already purchased the Tippmann Gryphon paintball gun, I still have not purchased the HPA tank. This is because I have been confused either to use the carbon dioxide gas or hydrogen gas in order for my shuttle projector.

So, after some extensive research through the internet, I decided to buy a high pressure hydrogen tank. Also referring to these information that I have gained on a web (above), I decided to buy a 48ci 3000psi with output of 800psi for my hydrogen tank. Through some consideration as I will need to do a test run for my project to record the data, I chose that particular specification (48ci 3000psi). With that type of specification, it can fire up to 590 paint balls which means it can also propel about the same amount of shuttlecocks for one tank of that specification. In my opinion, the tank has enough capacity for a test run and also during the Engineer's Day demonstration.

Below are some of the websites that I have visited to do some extra researches for my project. I found out that the websites are somewhat helping me a bit for my project.

 I have researched about the paintball gun, how to auto-trigger the paintball trigger so that it can propel the shuttlecock and also I have my consideration to use Arduino.

 Above is a picture of the website that I am thinking of controlling the DC servo motor with Arduino.

 Above is a picture of a website where I get to know a lot more regarding the type of paintball gun that I chose to do the project with, which is the Tippmann Gryphon.

The last picture above is a screen capture of  website that I surfed having a question regarding on how to trigger a paintball gun automatically.

BRAINSTORMING IDEAS (Week 5)

On the fifth week, I have met a friend of mine to discuss about my project. As I am new regarding making a final year project, i have asked for a friend of mine as a guidance besides having my supervisor too.

I have brainstormed with my friend looking at the project and also what other materials that i missed to list out. We had came out with a few of good and doable method in order to make my project a success.

When discussing about my final year project, I also learned how to make my project according to schedule and also neatly and tidily arranged schedule in order to finish my project on time.
