My name is Dmitriy Dudarev. I develop electronics, and I love to create different portable devices. I also love music. A long time ago, in April 2020 or so, when the whole world was shaken by the terrible quarantine, I decided to learn to play...
This article shows the basics of capacitor safety. 1. My Story When I was a teenager we used to Soviet mains powered have film projector. This project had a small AC motor, that was used to roll the film. It had a capacitor or varistor connected in parallel...
Although women represent nearly half of the world's population, the number of technology companies that address their specific health care needs is but a small fraction of the global technology market. In 2019, the Female Technology, “femtech,”...
Sometimes, when making your own devices on microcontrollers, there is a need to display huge amounts of information on a display and to use a bigger screen for ease of perception. Unfortunately, there are no ready-made and budget-friendly solutions for...
This project shows how to use the STONE display, STM32 microcontroller, ultrasonic sensors, and a servo. The purpose of the project is to be able to display the distance measured by ultrasound in real-time through the STONE display....
Have you ever made a processor? I did. Took me just 12 microchips and a clock generator. The processor can execute several commands, and programs can be written for it. The program code and input data are entered using micro switches, and the state of...
Let's get to some more real-world examples. First, we can look at a color-pill. Pick a color. If you search for "blue pill" or "green pill" or "red pill" and tac "stm32" on to the search, they all bring up useful information. ...
2018 UpdateST gets AtollicYes, "almost 2018", update. Interesting to see as noted @Hamish with the link he posted, STMicro acquiring Atollic IDE that was classified in this review as the most efficient. That makes sense. VSCode rules overWhere...
Part of the hits of 2018 has already come out, part - more will please us in the next couple of months. However, it is time to look into the more distant future and take up budget planning for future projects. So, we present to your attention the twenty...
SOT23 vs SOT323 Overview SOT23 and SOT323 are both plastic and surface-mounted packages. SOT23 owns 3 terminals, 1.9mm pitch, 2.9mm x 1.33mm x 1mm body, while SOT323 boasts 3 leads, 1.3mm pitch, 2mm x 1.25mm x 0.95mm...
So if you've seen damn near anything I've done for the last 18 months then you've seen examples of using Reverse Mount LEDs and also manually mounting LEDs upside down. A sample of my projects from 2018, all using reverse mounted LEDsReverse Gullwing...
As noted in our previous column, in the not-so-distant future we’re going to start creating simple circuits using resistors and light-emitting diodes (LEDs), but we first need to learn enough about resistors to ensure we use the right ones when the occasion...
[2 April 2023] So I was researching into input devices, and I had an idea: what if there was a way to use the SpaceExplorer I have in a shelf as a 2D mouse? Hear me out here! The main reason it was in a shelf was because I didn't want...
