Following this, we will configure bitwarden and host it on our Raspberry Pi 4. The last tutorial discussed utilizing a Raspberry Pi to install and run zeroTire on pi 4. By the end of the project, you will have learned how to set up a Raspberry Pi 4 with the necessary software for password management, including bitwarden, docker containers, and portainer, and how to configure their respective user interfaces.
Why Would You Do This?
An effective password manager is a must-have. For the past decade-plus, I've relied on a password manager. The catch is that not all security-focused apps are created equal. Initially, I relied on password managers in my browser, but I soon switched to KeePass. It was an intelligent move ten years ago. The export f ...
Welcome to the next tutorial in our Raspberry Pi 4 programming tutorial. In the previous tutorial, we learned the basics of using a Raspberry Pi as the basis for an Internet of Things-based weather station. However, this is a continuation of the previous tutorial. In the subsequent session, we will learn how to develop the Python code that will bring our weather station circuit design to life. Before that, let us learn how to measure wind direction and rainfall.
Wind direction
Wind vanes
Despite their name, wind vanes do not indicate a change in wind direction. Since the arrow on most television weather maps goes in the opposite direction, this may come as a surprise at first. To determine the wind's direction, a wind vane uses the force of the wind on a vertical blade, which then spins ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Affect of Noise on Signal in MATLAB. Noise is basically an unwanted signal that effects the normal signal. Noise the natural signal which can be removed but can be reduced to some extent. We can see a lot of examples of the signals effected by noise in our daily lives e.g. the distorted voice signal while calling, creates hearing problems, distorted TV signal makes the video invisible and the distorted AC signal can burn most of the home as well as other appliances.
In signal processing term, noise is also known as the unwanted signal which carries no useful information. To recover the original signal from the noise effected one, ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to provide a detailed discussion on Introduction to LM258. LM-258 has two internal Operational Amplifiers (Op-amps) which are frequency compensated internally. They are specially designed to perform their tasks from a single power supply source using a wide range of voltages. They can also perform different operations using split power supply. LM-258 low power supply current drain does not depend upon the magnitude of the power supply source.
LM 258 has a lot of features including high DC voltage gain, large bandwidth, different input voltage equal to power supply, large output voltage swing, common mode input voltages include ground. These were the few of m ...
Hello Guys! I welcome you on board. Happy to see you around. In this post today, I’ll walk you through the Introduction to Arduino MKR GSM 1400.
The Arduino MKR GSM 1400 is a microcontroller board that is based on the SAMD21 microcontroller. This device connects with a cellular network for developing communication. This GSM board is a one-stop solution for developing your sensor network or you can use it as a device sending a text message about the occurring of certain events remotely.
A module from u-blox, the SARA-U201 (which is a power chipset that activates using multiple cellular range bands) is responsible for GSM / 3G connectivity inside the device.
I recommend you read this post till the end as I’ll detail the complete Introduction to A ...
Hello everyone. I hope you all will be absolutely fine. Today, I am going to share an Introduction to LabView. LabView is a really exciting software and recently I have worked on many LabView Project so I thought to start this new set of series in which I am gonna explain all about LabView from beginners level to Pro Level. So, today I am gonna upload the first tutorial in this LabVIEW series so that's why I have named it Introduction to LabView and I hope you are gonna like this tutorial. :)
LabVIEW basically stands for “Laboratory Virtual Instrument Engineering Workbench”. This software is designed by the National Instruments (NI) for the control and design of the projects. You can use it for simulation purposes, can also interface hardware with ...
Hello everyone, I hope you all are doing great. In today's tutorial, I am going to share 5 Tips for Extending Your SCADA System. What do you do if your existing SCADA system isn’t doing the job you need? Obviously, you need to extend it, but doing so can be a frustrating and costly exercise. How do you manage budget, increase efficiency and provide the functionality you need? Of course, it all depends on your specific implementation, but some general tips to keep in mind might relieve some stress.
Look at The Big Picture Again
When you find your SCADA system can’t provide the data or control you need, the first instinct is to quickly patch the missing functions, but over the long haul this can be a costly and inefficient process leading to a tangle ...
In today’s fast-paced software development landscape, ensuring developer productivity and collaboration is more crucial than ever. As organizations scale, the complexity of managing workflows, tools, and services increases, often leading to inefficiencies and bottlenecks. Internal Developer Portals (IDPs) have emerged as a vital solution, addressing these challenges by centralizing tools, streamlining processes, and empowering developers with self-service capabilities.
What Are Internal Developer Portals?
Internal Developer Portals (IDPs) are centralized platforms that serve as a single point of access for engineering teams to manage tools, workflows, and resources. They are designed to simplify development processes, reduce cognitive load, and streamline collaboration by integrating wit ...
Hi Friends! Hope you are doing well. In this post, I'll uncover the details on How to use pinMode Arduino Command. The pinMode defines the Arduino Pins, if they are used as an input or output. The INPUT_PULLUP is another option achieved by pinMode, that is mainly used to place a virtual pull-up resistor to the input pins.
We have started Arduino Tutorials for Beginners quite a while now for the newbies, who are really interested to get a hands-on experience with Arduino. Generally, Arduino is known as a Microcontroller, but it is a step ahead of it. The PIC microcontrollers require some basic circuit to start with but Arduino brings revolution in the automation industry by removing the need of developing any basic circuit. Although Atmega328 is th ...
Hello learners! Welcome to the next episode of Neural Networks. Today, we are learning about a neural network architecture named Vision Transformer, or ViT. It is specially designed for image classification. Neural networks have been the trending topic in deep learning in the last decade and it seems that the studies and application of these networks are going to continue because they are now used even in daily life. The role of neural network architecture in this regard is important.
In this session, we will start our study with the introduction of the Vision Transformer. We’ll see how it works and for this, we’ll see the step-by-step introduction of each point about the vision transformer. After that, we’ll move towards the difference between ViT and CNN and in the end, we’ll discuss th ...
