Hi. I’m Dien-Nhung Nguyen (Nguyễn Phú Điền Nhung) - Author of KIENLAB.

If you see a nickname kienvo elsewhere, that’s probably me. This site archives things I’ve learned to reuse by myself or to anyone who is interested. The reason why this site name and my nickname have kien in it is it’s just a makeup name that I use when I don’t want to expose my identity. Now it is not important but the legacy still remains.

I have been an electronics hobbyist since a child. My father, an electrician has multiple kinds of electronic instruments and books about electronics in the house. Without his guidance, I read the books and built various analog circuits from basic to complex for my needs with components that I found around his workbench. My main focus at this time is to build RF transmitter circuits and high-voltage boosts.

In the 7th grade, the internet came to our village, I learned to program AVR on a series of blogs at HocAVR. My first project with a microcontroller was a watch with a 128x64 dot screen and used AT89s52 to read RTC and draw it on screen. It was inspired by Lê Đắc Đảm. As I have been playing with microcontrollers since then, I had a good experience with C programming. In the 9th grade, I got my first laptop, and my GPA was drastically going down because I spent all my time finding interest in microcontrollers. […]

In the grade of 10th, I first installed Ubuntu on my laptop. I was curious about how Linux and OSes work, so I started to develop a small OS from scratch following tutorials on osdev.org. During the development, I faced many open-source tools and had to learn to use them. I learned a lot about how computer architecture works.

Currently, I am a junior student at IUH, pursuing bachelor’s in Computer Science. The reason why I choose CS is I don’t want to be limited in the electronic field. But that does not mean I don’t have any deep knowledge of electronics. I’ve been doing freelance electronic projects to cover living since I went to uni.

Please drop a greeting at dien.nhung at kienlab!com. I am willing to talk about anything that is run by electricity.
