Know Your Car Basics 101: Bad Car Starter – Crucial Engine Component

Starter Motor Engine Ignition Car Vehicle Engineering

A car starter motor is a compact electric motor designed to crank an internal combustion engine to initiate its operation. When the ignition key is turned or the start button is pressed, the starter motor draws power from the car’s battery to rotate the engine’s crankshaft, creating the initial combustion needed for the engine to run independently. Typically, it engages the engine’s flywheel via a small gear called a pinion, which retracts once the engine starts to prevent damage. Image source: Samarins

Technology 101: The Illusive Blue LED – From Myth to Reality

Blue LED light emitting diodes Electrical Electricity Computing

The blue LED, a pivotal innovation in lighting technology, was developed in the early 1990s by Shuji Nakamura, along with Isamu Akasaki and Hiroshi Amano. This invention was significant enough to earn them the Nobel Prize in Physics in 2014. Blue LEDs are essential because they have a higher energy gap, allowing for the production of blue light, which, when combined with red and green LEDs, can create white light. This advancement has led to energy-efficient lighting solutions that are revolutionizing industries and consumer products worldwide. Photo by panumas nikhomkhai

Makeover 101: Part 4 – Learning Basics of LED Light Installation

LED Home COB House

My first large-scale experience with LED lights is when I decided to get an electrician to add new fans in the bedrooms and replace all the fluorescent lights in the house with brighter, more lasting lights. In some places like the living room, I added extra double lights which make the whole area very bright. There was not much work required for replacing fluorescent with LED lights but working with LED strips for the kitchen cabinet is going to be different. Photo by Max Rahubovskiy.

Technology 101: Environment Friendly Home Solar in Malaysia

(The entire home solar set is expected to cost house owners RM60,000 – it is not cheap but the return of investment does look favourable. If there are special funds for house owners to part-finance the set-up cost and then tie the repayment to the monthly FiT, that will promote greater use of solar panels at residential areas.

It looks like many Malaysians are also still in the “dark” when it comes to the environment and efforts being taken on the conservation

Environment 101: Exploring Alternate Energy Source in Malaysia

home solar environment green energy

I was reading an article on how solar energy panels on the orbiting space station power the cooling systems. I was wondering why we can’t do the same thing in Malaysia. After all, sunshine is abundant in Malaysia and an air-conditioner (or simple ceiling fan) needs power. Image source: http://www.eurocosm.com/)

Why can’t we match the two and have a cheaper power source at our disposal?
