Many guitarists consider the DS-1 to be the worst-sounding guitar pedal. Could this 1978 Roland design be a failure and is now hopelessly outdated?However, the idol of millions, Kurt Cobain, the author of world-favorite solos John Frusciante, and electric...
We don't really see too many walking robots around us, but everyone knows how they should look like. After all, we've seen a lot of them in the movies, comic books, and computer games. There is a slight problem with that. You see, those robots were conceived...
Happy bloody new year. In my last post, I mentioned that I was trying some new things. My long-gestating fan controller (Windy) finally taking physical form is exciting (if maybe a little slow), but I've got some other things on my plate that I'd like...
The awesome Colpitts oscillator. Exploring the secrets of the Colpitts generator.Hello, and welcome to our electronic studies! We probably all know that an oscillating circuit consists of a capacitor (C) and an inductor (L), and its waveform is an ideal...
In this project, we are going to use a very popular motor driver IC called an L293D. The advantage of using this chip is that we can control two motors at the same time, as well as control their direction. The chip can also be used to control a...
In the not-so-distant future, we’re going to start creating simple circuits using resistors and light-emitting diodes (“Ooh, Shiny!”). However, in order to warm ourselves up for this awesome experience, we first need to learn a little more...
It’s been four months since the previous article was written, and I have a lot of news both in the technical part and in the positioning of the device. Let me remind you of the requirements I set for the device when I started its development: It...
Printed Circuit forums (PCBs) are vital additives in the electronics enterprise. They play a critical function in connecting electronic additives to gadgets, machines, and systems. But, now not all PCBs are created identically. In relation to high-frequency...
First, the main parameters of the PCB board 1.1 Dielectric constant (Dk) Dieletric Constant Characterize the dielectric properties of dielectric materials or polarization properties of the physical parameters, its value is equal to the material to be...
I almost built a 1954 Regency TR-1 superheterodyne transistor radio.It was the very first commercially available radio receiver in the United States and globally, built entirely on transistors. How much have inner and outer designs changed in 69 (excellent)...
Brief Tutorial: Use the STM32 development board and STONE LCD screen to develop beauty devices with touch screens Figure 1 Because I have a lot of contacts with ST, MCU like this type can generally plug in the screen through IIC or SPI or serial...
In 2021, the global electronic manufacturing services (EMS) market size was valued at $500.26 billion, which is expected to grow at $849.72 billion in 2028 with a CAGR of 7.9%. The whole market grows rapidly which is driven by industries like...
Well, hello there, how nice to see you again. Everything we’ve talked about thus far has laid the foundation for what is to come. In the case of this column, this means we are poised to perform our first hands-on experiments with real electronic components....
notes: Here we want to make a project for the medical ventilator +STONE touch screen +STM32. In this project, we can choose the language and function, and draw the respiratory waveform by the way of random number triggering. When the key is pressed,...
Brief Since December 8, 2019, several cases of pneumonia with unknown etiology have been reported in Wuhan City, Hubei Province, China. In recent months, nearly 80000 confirmed cases have been caused in the whole country, and the impact of the epidemic...
