Week 10 Semester 2

Gyroscope

In this week, I will explain about the gyroscope. Gyroscope is use in this quad copter because to get easily the orientation of a non-moving object (pitch and roll), a 3-axis accelerometer can be used. For a static object, it gives the value of the gravity field on 3 axes, therefore its direction. The most common used sensor in quad copter control boards is the gyroscope sensor. It gives the angular rate around the 3 axes of space.

Week 9 Semester 2

Circuit Problem.

For this week there have a problem occur during construct and test the circuit. The problem is at the Micro Controller is burn. The problem can be solving by checking back properly the circuit and show there is short circuit. It is because of wrong supply. The problem is solving by redesign the circuit

Week 8 Semester 2

Construct the circuit

In this week, I continue back my progress on my circuit. I used printed circuit board(PCB). I choose this circuit because it easier than use strip board. To customized PCB, all I need are PCB board, acid hydrochloric, small drill, thinner and steel brush.

First, print the circuit design to the PCB board. Print on glossy paper or photo paper. Iron the printed design over the copper side of PCB. After the ink is transferring to PCB board, dip the PCB into acid hydrochloric. After 15 minutes, rinse it with water and rinse. The thinner are use to remove the ink. Use drill to make hole for the component to be solder.

Week 7 Semester 2

Quad copter circuit system operations.

For this week, I will explain about the circuit system operation for the quad copter. First, from the battery, voltage travel through the electronic speed controller than go to the motor. This is for supply to the motor. For the circuit, from the battery, voltage travel through the voltage regulator that produces 5 volts than go to the sensor (gyroscope), receiver (5DOFIMU) and Micro Controller (Atmega328). From the Micro Controller go to the ESC and motor. 

Week 6 Semester 2

Design the circuit.

In this week, I started to design the circuit. I have a problem to design this circuit. For your information, this quad copter is using arduino programming. Because of this problem, I have made some research about the circuit. I found a source from the forum quad copter in the internet. This forum discuss about the how to make the quad copter for beginner. From the forum, I had an idea to make a circuit and it is my source. Ic that I choose is atmega328.

Week 5 Semester 2

Assemble the project for mechanical part.

In this week, I have to assemble the mechanical part. The frame, landing skid, motor, and propeller are constructing together. Below shown I have been constructed my project for mechanical part.

Week 4 Semester 2

Buy equipment.

For this week, I went to the Jalan Pasar to buy some items needed to complete my project. I bought 4 Electronic Speed Controller (ESC), wire connectors, blades, battery and board. The expenses for this all item are RM1000.
