How to setup a Raspberry Pi security camera for home surveillance with Raspbian Buster Lite and motionEye

Even though a Raspberry Pi security camera is not the cheapest surveillance camera, it can be worthwhile building one.

Especially for Raspberry Pi fans, you may have several unused Raspberry Pis because you buy one for each release. In such a case, a big part of your Raspberry Pi security camera is sunken cost.

Given that, let’s look at how we can setup a Raspberry Pi security camera with Raspbian Buster Lite and motionEye.

Cool Raspberry Pi 4B cases that cool your Pi 4B

As I had mentioned in my review of the Raspberry Pi 4 Model B, the Pi 4B can overheat.

After I did a review on Seeed Studio Blink Blink ICE Tower CPU Cooling Fan, I am convinced that small heat sinks are inadequate in cooling a hot Pi4B.

If you are facing same issues, here are some cases to cool your Raspberry Pi 4B.

How to setup the Raspberry Pi Official 7 Inch Touch Screen with your Raspberry Pi 4 Model B

As I have noted in my review on the Raspberry Pi 4 Model B, the Pi 4B came with substantial upgrades.

Since it has faster (and more) RAM along with better graphics processing capabilities, the Pi 4B is well suited for multimedia deployments.

Given that, you may want to add the Raspberry Pi Official 7 Inch Touch Screen to your Pi 4B so that you can use it to build a kiosk.

If that’s the case, read on to see how to setup the Raspberry Pi Official 7 Inch Touch Screen with your Raspberry Pi 4B.

How to setup a Raspberry Pi LEMP server with Raspbian Buster Lite for running PHP applications

Many useful applications are written in PHP backed by MariaDB/MySQL for data persistency.

When you wondering what you can use a Raspberry Pi for, one way is to turn it into a LEMP server for hosting PHP applications.

With this in mind, let us look at how we can setup a Raspberry Pi LEMP server with Raspbian Buster Lite for running PHP applications.

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 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.

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.

How to enable SPI master driver in Raspbian using raspi-config

Your Raspberry Pi has the ability to communicate with hardware using the Serial Peripheral Interface specification. However, this master driver is disabled by default.

If you want to use the SPI master driver to communicate with devices, then you will need to enable it.

Let’s look at how we can enable the SPI master driver using the Raspberry Pi Software Configuration Tool (raspi-config).
