Web application for user hardware

-
I've been looking for something to find in webtechnologies, which will allow me to get interesting information about the user's computer. I needed something on the client-side. After a tedious search, I used Javascript for common things like operating system, resolving, browser.

I have also encountered WebGL technology that works exclusively under Chrome, but it offers a deeper view of the user's computer. WebGL can detect the depth of the color buffer, the number of processor cores, including virtual ones, the name of the DirectX graphics card.
The application utilizes a total of 8 javascript files that allow you to obtain this specific information about the client's hardware. The web app also works on Android smartphones. Note the interesting thing that computers have a 24-bit buffer and Android phones 32-bit.

Where does this application have use?
Internet contests for the most powerful graphics card, player rankings based on graphics card and processor cores, OS filtering and other specifics.
DEMO TO EXPLOIT: https://arduino.php5.sk/hardver/
Use Chrome! Otherwise, your app will not show the name of the graphics card and the DirectX version. Make a comment with your graphics and kernels :)

Web scraper via Arduino & NodeMCU & ESP32

Today, we will devote our microcontroller and its general use to a rather unusual purpose. Specifically, I will be talking about how I made a microcontroller from a webscraper. (If this can be called when processing your own backend information). As many of you know, a web scraper is a device that performs the task of retrieving information from that web site. The most wanted information from websites is e-mail addresses, phone numbers. Recently, however, this phenomenon is also used for a variety of statistical tasks where the scraper receives data on products, their prices, and evaluates them. Even similar devices are used as robots for trading with cryptomas or common names. At the most appropriate time (statistically) the robot pedal and bought another - a suitable menu with a rising tendency. In my case, I was interested in getting information from websites, specifically phone numbers and email addresses. We will therefore go directly to the realization. I have used 3 kinds

ESP32 control via UDP datagrams

Today I would like to point out the possibility of controlling the ESP32 development board by sending UDP messages for easy ON / OFF control. This is one of the easiest ways to send data, process it, and take action based on the information received. ESP32 is a platform that is used in most cases in connection with WiFi connectivity as a webserver or webclient, which connects to a remote server and POST, GET method, or with the integration of the MQTT protocol, sends data to a remote server / guest. Libraries for ESP32 written in C++ Arduino core (framework) also allows to use asynchronous UDP libraries for sending and receiving data. An interesting feature is asynchronicity, as they work in the "background" and the user does not have to program complex functions to accept connections, process information, etc. To send data to the ESP32 development board, we need a simple UDP client. In my case, I used the Windows version of the relatively well-known Packet Sender client. It

Biking on Google Maps - Arduino Leonardo (32u4) - HID device

Cycling is a very popular sport, also thanks to the successful athlete Petr Sagan. Passionate cyclists roam our roads and paths. However, as the weather is not always good, not only a fan of bicycles would like to ride from the comfort of home. So today I am bringing a way to do this, say, the augmented reality of Google maps. At the beginning we will go through the necessary hardware resources for the project and in the next step we will discuss their functionality. Hardware Components: Arduino (32u4 CPU) Leonardo  Magnetic reel switch  2x pushbuttons  To use the system, the user must turn on Google Maps, select any site in the world and switch to Street View mode. This ensures a ready interface for interacting with the bike (Arduin). Any type of bicycle can be used. Classic, road, mountain, treadmill. A magnetic contact must be fitted on the pedal and the structure. The main element of the system is the use of the Arduino Leonardo development board, which contains an AT
