Hi Guys, While I was searching for photoelectric device to demonstrate the photoelectric effect . I found these two kits in Alibaba but the parts i encircled in white i dont know what are they!! And where to find them. Could any one help and thanks

So there are many electronic 'air' drumsticks in the market, such as Aeroband, Freedrum, Senstroke, Aerodrums, etc. I wanted to know what sensors do these use or might have used to do what they do. For example, the Aeroband Pocketdrum have a pair of drumsticks with sensors, and a pair of foot...

Every real-world project comprises interconnected systems. Can you suggest any courses that provide insights into comprehending systems and their role as integral building blocks in projects? I am an electronics engineer seeking relevant recommendations.

Hello guys, so i have an electric sit stand desk and it stopped working a while ago, i opened up the control box model TC15L from TI motion, and saw the IC in the pictures was fried so much so that it was impossible to read the part number off of the IC. Upon touching this IC, it blew away like...

So i'm currently trying to take parts out of a Bluetooth speaker's circuit-board and find the Bluetooth module for a DIY project. I looked at the board and some ICs and tried looking them up to no avail. So How Do you read an IC or any other components on the board Or even find a schismatic...

Hi, in IEEE 3 bus, why are circuit breakers connected at the 'load' rather than connected at the 'generator and load'?

Hi people I would like to make a digital clock with HOURS and MINS using 74LS192 IC. Below attached is my schematic diagram for the connection of the circuit. However, the MINS counter keeps counting from 00-59 and resets and does not increase the HOURS counter after each 60mins. Components...
