Gadget Recommendations

Gadgets are necessities to most IT professionals, especially for people who like to build things and communicate with the world wide web in front of a laptop or desktop. This category is for collating my thoughts on some of the gadgets that I enjoyed using in my daily life.

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 capture images in the dark with the Raspberry Pi Infrared Camera Module from Seeed Studio

When I wanted to keep tabs on my corridor, I built a Raspberry Pi Zero W surveillance camera with MotionEye and Raspbian Lite.

After a while, I make my Raspberry Pi Zero W see an ultra-wide view by using one of the Fish Eye lens from a Camera Lens kits that I received as a gift.

Since then, I am able to have a wide angle view of my corridor as long as I have a browser with an Internet connection.

However, the same setup will not work for checking on my plants in the kitchen. If I am to snap some pictures after my LED growth lights are switched off, I will definitely get pitch black images.

So what kind of camera should my plant surveillance setup use? In order to capture images in the dark, I should look for a camera without the Infrared Filter – a NoIR Camera.

With this in mind, I head over to Seeed Studio and got myself the Raspberry Pi Infrared Camera Module.

Since Seeed Studio had provided me with a voucher for this purchase, I am able to minimize the cost of producing this article.

Thank you Seeed Studio!

Given that, let’s see how we can capture images in the dark with the Raspberry Pi Infrared Camera Module.

Why buy the Raspberry Pi Zero W?

When you have seen the Raspberry Pi 4 with 4GB ram, you may wonder why should we even be bothered with the earlier versions.

If you have been following Seeed Studio, you may have heard that they had included Raspberry Pi Zero W in their product catalogue.

I welcome this move from Seeed Studio with open arms.

Since I live in Singapore, I will be able to shave hefty shipping costs getting the Pi Zero W from Seeed Studio instead of vendors from the west. If you are staying in countries that are nearer to Guangzhou, then the real cost of your Pi Zero W will be much closer to the 10 USD price tag.

But why buy the Raspberry Pi Zero W?

In case you are thinking of whether to trade 10-ish bucks for one, here are some reasons why you should have a look at the Raspberry Pi Zero W for your next Raspberry Pi project.

A review of the Raspberry Pi 4 Model B from a not-so-early adopter

When a single board computer has 4GB of RAM, you can use it as a capable IoT gateway or desktop computing. In addition to that, the Raspberry Pi 4 Model B maintains the same dimensions as its credit card sized predecessor, the Pi 3B+.

Although there are several single board computers which provided 4GB of ram, they are priced more than the US$55 price tag. Given that, the Raspberry Pi 4 Model 4 with 4GB of ram is a very attractive offering.

Why buy Logitech MX Master 2S wireless mouse?

When my mouse cursor starts jumping around the screen randomly, the search for a better mouse begins.

Since I had been using a budget mouse for nearly a decade, I decided to go with comfort and efficiency for a change.

After doing some research, I got myself a Logitech MX Master 2S wireless mouse. That turns out to be a pretty good investment for me.

In case you are looking for a new mouse and need some buying reference, here are some reasons why I like my Logitech MX Master 2S wireless mouse.

Why buy Synology DS418 NAS?

Since my adoption of digital imaging and other content creation, I had gathered huge amount of digital artefacts in my laptop. Finally, there came a day when my data was going to outgrow the hard disk on my laptop. Hence, I took the decision to invest in a Synology DS418 NAS to help me keep my data.

In case you are deciding whether to buy a Synology DS418 NAS, here are some reasons why I bought the Synology DS418 NAS.

Helpful GPIO Pinout resources that you can reference while connecting sensors to your Raspberry Pi 3

Undeniably, the GPIO (general-purpose input/output) pins along the top edge of your Raspberry Pi 3 board is what makes it so useful for IOT projects. In case you are curious, this is how the GPIO pins looks like on a Raspberry Pi 3 B+:

GPIO pins of a Raspberry Pi 3 B+

Although there is the word GPIO on the circuit board that indicates what those pins are, there is no indication on what each individual pin does.

So how do you know which pins to connect your sensors to? Thankfully, there are several good resources that you can reference while connecting sensors to your Raspberry Pi 3 board.

In case you need it, here are some helpful GPIO resources that you can reference when you are connecting sensors to your Raspberry Pi 3 board.

Getting started with an Nvidia Jetson TX2 developer kit

When we have the right amount of data, machine learning enables us to use them for building a model that can provide answers for future questions.

Compared to CPUs, a GPU is better suited for us to build that model. This is because a GPU is very good at performing much more computations in parallel.

Although you can build your own GPU rig for machine learning, an Nvidia Jetson TX2 developer kit is easier to setup and more energy efficient. Therefore, I got myself a Nvidia Jetson TX2 developer kit to ride on the machine learning bandwagon.

In case you are wondering what is in the box and how to get started with an Nvidia Jetson TX2 developer kit, read on to find out more.

Setting up a low cost desktop computer with Raspberry Pi 3

With the advent of single-board computers like Raspberry Pi, we do not have to spend too much money on a computer that can fulfil our basic computing needs. The launch of Raspberry Pi 3 was like icing on the cake; it came with WiFi connectivity. Since WiFi is ubiquitous, the WiFi connectivity of the Raspberry Pi 3 made it a suitable candidate to be used as a low cost desktop computer in the house, office or school.

This post documents how you can setup a low cost desktop computer with Raspberry Pi 3.
