This post will be taken down soon.

The demand for special needs equipments, ranging from electronics to mobility equipments, is high in Singapore. However, the price of these items are not affordable due to a small market. Last week, I repaired a BIGmack simply by replacing the power connector ($0.50 on Shopee). For us, we are able to troubleshoot the problem easily. However, for many, they may assume the BIGmack is beyond repair and buy a new one which costs about $300. Imagine how much money one can save. Furthermore, a quick google search (1 min effort🥲) doesn’t show us where we can get these communicating devices repaired. Hence, people look to DIY for a cheaper alternative. If anyone is good with tinkering and building stuff, and wishes to take on some side projects, please drop me an email. Can earn some cash too. 😉

Complex number

Back when I was still studying in University, there wasn’t much time for me to just sit back and appreciate what I have learnt. There are so many questions that in me that remain unanswered. Out of the many questions, one stands out over the others. “How is Engineering Math relevant to the real world?”.

I have been spending some time lately, flipping through my lecture notes, trying to learn all over again with a new understanding. What I have gained from this is truly amazing.

Since many of us have to stay home for at least a month now, I encourage you to do the same too.


Before this blog becomes irrelevant, I would like to share some amazing YouTube videos that I came across a few days back. You may find these video very basic, but to understand the complexity of semiconductors, I feel that having a strong foundation is necessary.
