Articles about Raspberry Pi Zero W

A Raspberry Pi Zero W is a single-board computer that is half the size of a credit card. In addition to its small form factor, it comes with Wi-Fi and Bluetooth inbuilt.

Given these points, it is a piece of computing device that you should consider for building small and portable projects.

On this page, you will find articles related to Raspberry Pi Zero W. Topics include ways to build your own Raspberry Pi Zero W security camera, preparing a Raspberry Pi Zero W for running Python 3 applications and more.

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 static website on your Raspberry Pi Zero W with Raspbian Stretch Lite and Nginx web server

After you capture the Northern Lights with an entry level DSLR, you may want include them in your personal portfolio. Until you find the time to setup a content management system for your personal portfolio, you want to keep it as a static website.

At this point in time, you saw that Raspberry Pi Zero W and cover lying on the table. In addition to that, you have a spare micro USB charger that you used for charging your old Android phone.

Since you do not have any other use for these items, you decided to host your personal portfolio on that Raspberry Pi Zero W.

With this intention, this is how you can host a static website on your Raspberry Pi Zero W with Raspbian Stretch Lite and Nginx web server.

How to setup Raspbian Stretch on Raspberry Pi 3 for developing Python 3 applications

Previously, I had shared:

Although Raspbian Stretch Lite is ideal for running Python 3 applications on Raspberry Pis, it is not so handy for developing Python 3 applications.

For example, if you are building a Python application that interfaces with the GPIO ports and CSI camera of your Raspberry Pi 3, it is hard to test it out on Raspbian Stretch Lite.

Since Raspbian Stretch includes a desktop environment, it is more convenient for developing Python 3 applications for Raspberry Pi. With this purpose in mind, this is how to setup Raspbian Stretch on Raspberry Pi 3 for developing Python 3 applications.

How I use my Raspberry Pis to help me work on with my side projects

Undeniably, Raspberry Pi has revolutionised the way we use computing technology in our lives. In addition to being energy efficient, a Raspberry Pi is a single board computer that does not take up too much space.

Given these points, a Raspberry Pi is an ideal programmer gift and one of the things that you should buy if you are a computer programmer.

On the other hand, pursuing side projects help me explore technologies that I may not be able to explore at work. For example, through Techcoil, I got to know more about:

In case you are wondering how to use Raspberry Pis to help you work on your side projects, read on to find out more.

How to enable Raspberry Pi camera on Raspbian Stretch Lite

Previously, I had written two posts on how you can connect the Raspberry Pi Camera Module to Raspberry Pi 2/3 and Raspberry Pi Zero W:

When you install Raspbian Stretch Lite on your Raspberry Pi, you will need to enable the Raspberry Pi camera before you can use it.

In case you need a reference, this post will show you how to enable Raspberry Pi camera on Raspbian Stretch Lite.

Comparing the 0.67x wide angle lens and the Fisheye lens on a Raspberry Pi CCTV

Recently, I found a pack of Camera Lens Kit for mobile phones. Inside that pack, there is one 0.67x wide angle lens and one Fisheye lens.

Given that, I had created the following posts to show how you can put them onto your Raspberry Pi Zero W CCTV:

In case you want to see the effect of those lens before getting a pack to turn your Raspberry Pi Zero W CCTV or Raspberry Pi 3 CCTV into wide angle security cameras, read this post to compare the effects of 0.67x wide angle lens and Fisheye on a Raspberry Pi CCTV.

How to turn your Raspberry Pi Zero W CCTV into a wide angle security camera

When Raspberry Pi Zero W appeared in the market, I immediately got one and setup a Raspberry Pi Zero W security camera with motionEyeOS. In addition to taking half the size of a credit card, a Raspberry Pi Zero W comes with Wi-Fi inbuilt. Therefore, it is ideal for building a security camera that connects to your Wi-Fi network.

Previously, I wrote about how to make your Raspberry Pi Zero W camera see an ultra-wide view through a Fisheye lens.

Since the pack of Camera Lens Kits for mobile phones includes a 0.67x wide angle lens, I decided to use it to turn my other Raspberry Pi Zero W CCTV into a wide angle security camera.

If you need a reference, read this to find out how you can turn your Raspberry Pi Zero W CCTV into a wide angle security camera.

How to configure motionEye to only capture video if there are movements in particular sections of the surveillance area

Undeniably, Calin Crisan had created one of the best way for us to build a Raspberry Pi security camera. In addition to the ease of setup via motionEyeOS, the motionEye web-based frontend is also easy to use.

Since a Raspberry Pi security camera is used for surveillance, we will want it to record videos of things that happened when we were not looking.

However, recording footages of the surveillance area when there were no motion being detected is wasteful. Moreover, it is hard to get to the video recording of a stranger moving your flower pot when there are too many redundant video clips in your Raspberry Pi security camera.

Even if we switched on motion detection for the entire video frame, there could be motion detected outside of the area of interest. For example, we may be interested in birds resting on our plant rather than birds flying in the sky.

So how do we configure motionEye to only capture video if there are movements in a particular section of the surveillance area?

This post will show you how to do so.

How to make your Raspberry Pi Zero W camera see an ultra-wide view

While I was organising cabinet, I found a pack of Camera Lens Kits for mobile phones.

Since I am using my Raspberry Pi Zero W as a surveillance camera, I figured that it would be useful if I can use the Fisheye lens in the pack to make my camera see a wider view.

This post shows how you can make a Raspberry Pi Zero W camera see an ultra-wide view.
