This time I bring an electronic kit for beginners, this is a very cheap and interesting device that displays audio levels ...

In a recent video [QWZ Labs] demonstrates an interesting technique to use 3D printing to make creating custom PCBs rather straightforward even if all you have is a 3D printer and a roll of copper tape ...

I used my very limited inventory to design, some of the resistors and capacitors connected in parallel/series to obtain original values. LM317 is used to convert 3-30V input voltage 3.3-5V output ...

Abstract: There are problems such as poor accuracy and large number of parameters in the detection of small target defects when the YOLOv8 algorithm is applied to PCB defect detection. In response to ...

This software is meant to help you indentify issues with populated printed circuit boards. You provide a reference image of the "good" PCB and then the software shall analyse additional boards and ...
