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.
