The premise of the project was to create a programmer from scratch for popular Flash NAND memories, in order to fill a gap in the market in the low-budget segment of programmers. Sometimes there is a need to read a Flash NAND chip found, for example, in a memory stick, but also in... [Read more]
Some hard drives have a serial interface with pins next to the SATA connector. Basic information can be found in the topic: Seagate and Samsung HDD FAQ plus terminal - short description . Communication with the disk via the UART interface is usually used for failure diagnostics or... [Read more]
A long time ago in devices read-only data was stored in EPROMs. These types of memories were electrically programmed and erased with UV radiation. Erasing was possible thanks to a quartz window in the housing (there were also cheaper one-time programmable memories without a window... [Read more]
Hello to all forum members. Phew how hot. ;-) Today I would like to present you my holiday construction, it has little to do with electronics, but I think it is an interesting solution for summer heat. Let's start from the beginning. The project was inspired by the topic of heating... [Read more]
Hi, Over a year ago I made a multimedia system based on the Nexus 7 tablet. The goal was to create an interface that would provide many functions previously implemented by several devices. Assumptions: - Yanosik support on a large and clear screen and playing messages through the... [Read more]
The question of the 120V 60Hz AC power standard in the USA is a common cause of confusion. First of all, not only the USA uses 120V in its home electrical system. There are also differences in "higher" supply voltages depending on the country, there are standards of 200V, 220V, 230V,... [Read more]
One very good method of filtering high frequency interference and noise from the power line, especially when it is shared between multiple circuits - digital and analog - are ferrite beads. These are passive components that help to filter out some of the high-frequency noise for which... [Read more]
Hello After a long time, I finally gathered myself to collect all the photos and videos of my project in one place and publish it on the forum. The construction is about two years old. I did the job when I was in the 3rd class of technical secondary school in mechatronics profile.... [Read more]
Hello. Some time ago I was looking for a way to communicate with Logitech wireless peripherals in order to use them in my own projects. Due to the recent reports on the possibility of impersonating someone else's keyboard / mouse, I decided to boast myself. I don't know how... [Read more]
The author, while shopping with his girlfriend, had quite a lot of time to think and look around. As he wandered from store to store, a mirror displaying inscriptions caught his attention. It was then that he had the idea to build a similar one, but better for himself. Your own magic... [Read more]
Lead-acid batteries are still present in many devices, despite the availability of modern lithium polymer, lithium-ion or supercapacitors. The affordable price of lead-acid batteries and the simple design of the charger make them a popular source of energy for both buffer and cyclic... [Read more]
Hello, hello and hello! The idea of building a 3D printer has been on my mind for about a year, I finally took it as an engineering subject and got motivated. :) I decided to model it after the existing Artifex, as you can see. In general, the main criterion for selecting components... [Read more]
This article will describe how to display and record car diagnostic information with a Raspberry Pi. Step 1: Required materials To complete this project you will need: o Raspberry Pi Model B or B + o Car stereo (must have an AUX socket) o Bluetooth adapter o Car charger o USB or Bluetooth...

As is well known, SSDs are the successors of traditional hard drives that operate using magnetic media. The new generation exceeds the old one with various parameters, e.g. faster reading and writing or no need to defragment. After all, Zack Whittaker in his article proves that data... [Read more]
Current measurement results in 5V and 12V branches of HDDs and SSDs. Currently, there are miniature platforms with SATA connectors that allow you to build many interesting devices equipped with capacious and fast hard drives. We checked the current consumption of HDDs and SSDs, the... [Read more]
From the electronics archive - how the analog system for imaging the Earth's surface from orbit worked, and how were data packets switched without internet? Photographs of the Earth from orbit in 1959. Nowadays, everyone can view satellite images of the Earth using a computer... [Read more]
Hello, I would like to introduce my Amstrad 464 microcomputer clone. Why did I make it? Well, mostly for educational purposes, besides, the original Amstrad 464 is awfully long and takes up a lot of desk space. ;) Mine takes less. ;) Diagram: Original diagram of Amstrad 464 I redraw... [Read more]
I was forced to do this by the price of the original transistors and the ubiquitous coloring. So, after analyzing a multitude of diagrams, I came to the conclusion why not to use easily available and commonly used mosfets in new radios. I went to work and it worked, so I wanted to... [Read more]
From the electronics archive - Electromechanical VLF transmitter Can the generator transmit? The antenna can transmit by radiating RF energy delivered by the transmitter in the form of electromagnetic waves. The transmitter output signal can be modulated both in amplitude and frequency,...
