Our Project

I have been very busy over the last couple of months due to my Final Year Project (FYP) and exams. With all that over now, things are still moving pretty fast for me. I was asked to present our project to an industrial company last week Monday, which I did, and, I'm also job hunting. For a little while now, I want to look back at those hectic months. The times when I was really stressed up and was at the verge of giving up. The times where pressure was so intense I would sometimes sit in front of my PC with a blank mind after running out of ideas on how to troubleshoot my program or hardware. Those sleepless nights, those tearless cries, all that to come up with this.

Our EV prototype
This is my group's FYP. Our topic is to do a study on battery car management system and then build a prototype. My focus was on the micro-controller. It involves writing the program as well as build some hardware. The other parts such as the charger circuit and some other circuitry of the car were done by my other 2 colleagues.

The front view
This prototype has most function of a real car from headlights to tail lights to indicators. There's also a wiper, a cute sounding horn, power window and of course, its wheels are able to turn in the forward and backward direction and a servo to control the left and right directions as well as the brakes. We did consider doing regenerative braking system but we didn't have enough time. So the part about regenerative breaking system remained just an idea. The functions of the car are controlled by a make-shift control panel.

The control panel

I even built my own PICkit2 clone, and it gets me excited just thinking about it =)

Looking back, all those stressful nights, troubleshooting and debugging, all of it, was worth it. I got to thank especially my colleagues and Michelle for all the help and work done.
