Hi, I am

Yeo Chai Heng


I was born in and am living in Singapore,

an island city-state with beautiful skylines.


I am currently employed as a Solutions Engineer @ PayPal


I am also a Management of Technology student @ NUS

I build things with tools from the computing world:

An easy way to install Raspberry Pi OS - using Raspberry Pi Imager

Once got an microSD card for your Raspberry Pi in your mailbox, you can install an operating system to run it.

Typically, we download a Raspberry Pi image and use one of the imaging software to write it to our microSD card.

When the Raspberry Pi Imager came into the picture, the download step is consolidated into a single workflow.

Given that, this is how you can use the Raspberry Pi Imager to install Raspberry Pi OS.

How to show the temperature and humidity of your room on a Heltec WiFi Kit 32 attached to a DHT11 / DHT22 sensor

When you have a DHT11 / DHT22 sensor, you can measure the temperature and humidity of your room. If you attach the sensor to a Heltec WiFi Kit 32 development board, you will be able to put up the readings on a 0.96 Inch OLED screen.

Given these points, let's look at how we can show the temperature and humidity readings of your room on a Heltec WiFi Kit 32 development board attached to a DHTXX sensor.

Why get a Wio Terminal for your next IoT project?

If you have 30 USD and is looking for a microcontroller, then you will want to consider the Wio Terminal.

Since Seeed Studio had kindly sent me one for free, I got to picture my 30 bucks alongside the box:

Wio Terminal front of box with 30 USD

Although 30 bucks is not a lot of money, it is good to know what the Wio Terminal is capable of before buying. When we do so, we can prevent adding on to that electronics stockpile which is collecting dust in the house.

Given these points., let's look at why you will want get a Wio Terminal for your next IoT project.

Why use a Raspberry Pi 4B as a desktop computer?

Ever since the Raspberry Pi first appearance, many people have been hoping to use it as a desktop computer.

When the Raspberry Pi 4B came along, we saw some upgrades that can turn those hopes into reality.

Given that, let's look at some reasons why you will want to use a Pi 4B as a desktop computer.

That's all for now...
