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 Presales Specialist @ SAP

 

I am also a Management of Technology student @ NUS

I build things with tools from the computing world:

Cool your Raspberry Pi 4 with the ICE Tower CPU Cooling Fan

As I had mentioned in why my computer restarted itself when I play League of Legends, excess heat can cause a computer to behave abnormally.

So how will your Raspberry Pi 4 Model B deal with rising heat? In case there is a spike in operating temperature, Raspberry Pi 4 will slow your CPU down significantly. When that happens, you will not be able to enjoy 4K videos on your Raspberry Pi 4 anymore.

After I did a review on the Raspberry Pi 4, I had been contemplating whether to get a cooler fan for my Raspberry Pi 4. In the midst of delayed gratification, Seeed Studio asked if I am willing to do a review on their Ice Tower Cooler. Since I wanted a cooling fan for my Pi 4, I agreed to have a look at the Ice Tower Cooler.

Given that, this post contains some points for your reference if you are pondering whether to get the ICE Tower CPU Cooling Fan for to cool your Raspberry Pi 4.

How to change the hostname of your Raspberry Pi, running Raspbian, with raspi-config

When you deploy multiple Raspberry Pis in your house, it is a good practice to give each of them a unique hostname. Since the default hostname for Raspbian is raspberrypi, it will be easier to look for the IP address of a new Raspbian installation in this situation.

Given that, let us look at how you can change the hostname of your Raspberry Pi in Raspbian via the Raspberry Pi Software Configuration Tool (raspi-config).

How to add a React component that rotates recommended items on your website

As I had mentioned in how to monetise a programmer's website effectively, affiliate marketing can be an effective way for your website to earn money.

Since affiliate marketing programs revolves around links, we can build a catalogue of items that we wish to recommend to visitors to our websites.

If you have already built that catalogue of product recommendations and an API endpoint, you can build a sticky component in your sidebar and rotates recommended items from there.

Since I have been hearing good feedback about React, I implemented such a feature on my website with React.

In case you are looking to do the same, this is how you can add a React component that rotates recommended items on your website.

How to read soil moisture level with Raspberry Pi and a YL-69/FC-28 moisture sensor

When I did a Raspberry Pi 4 Model B review, I got myself a Raspberry Pi 4 Model B. Therefore, the current Raspberry Pi 3 Model B+ that I have been using for validating Raspberry Pi ideas became available for another IoT project in the house.

So what should I do with my Raspberry Pi?

Since I have always wanted to build my own indoor herb garden, I plan to use it to help my plants grow well.

When I bought the LED Grow Lights, I am able to give my plants consistent lighting. Given that consistent lighting is solved, I can use my Raspberry Pi 3 to monitor soil moisture so that I can provide water my plants better.

Given these points, this is a proof of concept that I did to read soil moisture level with my Raspberry Pi and a YL-69/FC-28 moisture sensor.

How to use the MCP3008-I/P chip to help your Raspberry Pi read digital data from analog sensors

Although your Raspberry Pi is unable to read analog input out of the box, you can get a MCP3008 I/P ADC chip to help your Raspberry Pi do so.

MCP3008 IP ADC chip up close

When you connect a MCP3008 I/P chip to your Raspberry Pi, you can read up to 8 analog inputs with SPI.

Given these points, this post will show you how you can use the MCP3008 I/P chip to help your Raspberry Pi read digital data from analog sensors.

That's all for now...
