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.

How to host a WordPress website on a Raspberry Pi with Raspbian Buster Lite and Nginx

If you are thinking of starting a blog about computer technology, then you can consider hosting a WordPress website on your Raspberry Pi.

Since Raspberry Pi is a capable machine that does not take up too much space and power, it is a good as a web server.

In addition, if you have an Internet subscription that does not block port 80 and 443, hosting a WordPress at home can be cost effective.

Given these points, let’s look at how we can host a WordPress website on a Raspberry Pi with Raspbian Buster and Nginx.

How to setup Raspbian Buster Lite for Raspberry Pi server projects

When I did a review for Raspberry Pi 4 Model B, the idea of using the Pi 4 for server applications is clear. Since Raspbian Buster Lite was released alongside the Pi 4, we can use it for new Raspberry Pi server projects. If you are thinking of building Raspberry Pi server projects, then you […]

How to setup Raspbian Buster for your Raspberry Pi 4 Model B

Since the Raspberry pi 4 Model B comes with several nice upgrades, it is a single board computer that you may want to get.

After you got your Raspberry Pi 4 rig and microSD card, the next step will be to setup an operating system.

At this point in time, you may want to install one of the Raspbian Buster images that got released for the Pi 4.

With that in mind, read on to learn how to setup Raspbian Buster for your Raspberry Pi 4 Model B.

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.

How to start a blog about computer technology

Previously, I wrote about why programmers should blog. When you are convinced that you should blog as a programmer, you may wonder how to start a blog.

In order to have a place to refer people who wants to learn more about this topic, I write my experience in this article.

Given that in mind, this is how you can start a blog about computer technology.

How to setup a small and powerful computer with Ubuntu 19.04 Desktop and Odroid H2

After implementing some easy and effective ways to make money with my website, I was able to earn some budget for a developer’s machine.

So what is a single board computer that is small and powerful?

After doing some research, I set my eyes on the Odroid H2.

Once I had received all the hardware components, I proceeded with setting up Ubuntu 19.04 Desktop on my Odroid H2.

In case you need a reference, this is how you can setup Ubuntu 19.04 Desktop on an Odroid H2.

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.
