Switched Mode Power Supplies (SMPS) are electronic circuits that convert AC power from the mains into DC power that can be used by electronic devices. Unlike linear power supplies, which use a transformer to step down the voltage and a linear regulator...
You're never safe from a good surprise ! A renowned electronic parts store in Paris (one of the too few remaining) found an old box in the back of their warehouse and sold its contents for such a ridiculous price that I bought the whole box. I happened...
So while still waiting for HBSound's Prototyping sponsor, PCBWay, to finish up and ship off the prototypes for that project. I did have some time to work on the ZX81 Restoration. I am still working through the best way to clean...
Mental illness isnt funny, dont let anyone tell you otherwise.Some people are just loopy, and deliberately say things that disturb others' ordered trains of thought. Most of them make it onto a stage at some point, or at least earn a comfortable living...
ESP32 The ESP32 development boards are not without their problems. Why keep using them anyway? The ESP32 IC only costs €2.31/pce on Digikey. Design a decent breakout board and done! Well, if you don't want to design your own...
I'm building a BLDC ESC based on EFM8BB2 running BLHeli_SNCP81253 Gate DriverSIZ322DT NFET pairand a DMN2990UDJ fual NFET for level shifting between 3V3 (MCU) and the 5 V gate driver logic Link to current schematic (possible error in MCU to level...
In terms of the structure of product itself, the DC gear motor also belongs to an ordinary DC motor. What differs lies in a newly-added gear motor in its basic structure, which explains why it is called gear motor. This article will make a brief introduction...
Voltage regulators are electronic components that are designed to maintain a stable output voltage, regardless of changes in the input voltage or load conditions. Voltage regulators are commonly used in a variety of electronic applications,...
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...
The RPiRENA-based active dosimeter This particle detector works on the same principles as previously assembled dosimeter prototypes. Here, the detection system draws its power from the 3.3 V and 5 V...
The ball screw consists of a screw and nut with matching grooves and ball bearings that move between them. Its function is to convert rotary motion into linear motion or convert linear motion into rotary motion. Ball screw is the most commonly...
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...
Bipolar junction transistor (BJT): Bipolar junction transistors are those which contain both holes and free electrons for the transmission of electrons, as the diode is made up of two semiconductors join together to form a PN-junction, BJT is two...
Opening speechPreviously, we've reviewed several options for twisted-pair network cable HDMI extenders. We've also taken a look at their various functions. This time, i would like to focus on an interesting type of device: an HDMI splitter/extender via...
