High school is finally over! That being said, having chosen a technical school, I, like others, was asked to create a project to be shown during the oral interview with the exam commission. This post is meant to be sort of a postmortem for it. Now, my goal was to create some sort of PLC, capable of controlling high power loads....
Hello there, This oscillator is a 0V +10v DC oscillator, which after current passes through the capacitor, it produces a -5v +5v AC on the resistor....
My room thermometer is consuming a full stack 3 AAA batteries in just 24 hours. I opened it and found that maybe the component circled in green is burnt (CAZB)....
Here’s a power cable from a Cmt-ex1 Sony CD player. This connector used to be connected to the inside of the power supply. However, I had to disassemble it because I needed to replace the motherboard for the CD player. I found this CD player at Goodwill, but the wire was poorly connected with a completely different cable. It...

They are 4 traces, and all of them terminate at the same pad of the capacitor. As I have currently placed them, are they connected correctly? Or should I connect them in a different way?

I built mine from components from AliExpress and components found in old electronics so I thought nothing...
