When you encode your images in Base64, your images can be transferred and saved as text.
Although there will be a 37% bloat in space requirements, it can be useful to encode images in Base64.
For example with SAP HANA XS Advanced, you can quickly build an OData service to receive images via JSON.
Given that, let’s see how we can encode an image in Base64 encoding with Python 3.
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.
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.
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.
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.
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).
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.
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.
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.
