[Solved] Laptop Stuck on 0% Available (Plugged In)
As I can guess you’re here because your laptop isn’t charging and displays “0% available (plugged in).” I’ve experienced the same frustration with my own laptop recently. For context, this was a Gigabyte laptop running Windows 10. Without further ado, here’s a guide to help you identify and fix the…
PCB material properties
Often, when designing printed circuit boards (PCBs), people do not even think about the materials used for their production. Unfortunately, these materials are critical to the performance of PCBs. That’s why I decided to talk about what you need to think about when choosing PCB materials. This article will be…
Backfeeding in Electronics: What You Need to Know
Backfeeding is a concept that is often discussed but not always fully understood. Backfeeding, in the context of electronics, refers to the flow of electricity in a direction opposite to the intended flow. This phenomenon primarily occurs over the signal path and can be attributed to signals crossing different power…
TLDR: What is a capacitor
A capacitor is an electronic component that stores and releases electrical energy. It has two plates separated by an insulator. When you apply voltage to it, one plate gets a positive charge, and the other gets a negative charge. It stores this charge and can release it when needed. Capacitors…
Accurate Temperature Measurement Using an NTC Thermistor with an Arduino or STM32 Microcontroller
In this blog post, we will explain how to design a circuit to directly monitor temperature using an NTC thermistor with an analog-to-digital (ADC) converter on any microcontroller like an Arduino or STM32. What is a NTC thermistor An NTC (Negative Temperature Coefficient) thermistor is a type of temperature sensor…
Zero-ohm resistor power rating
In the world of electronic components, resistors play a crucial role in limiting or regulating the flow of electrical current in an electronic circuit. From the common carbon film resistors to the more specialized high-power resistors, each variant serves a specific purpose. However, there is one peculiar member of the…
Automotive power supply circuit considerations
The first time you ever designed an electrical circuit for a car or motorcycle, you probably thought that the maximum voltage that your circuit would see was around 14.5 volts, which is the output of the alternator. In an ideal world, you would be right, but this world is not…
BMW tail light LED repair
If you own a BMW E92 or E93, you may experience issues with a trunk tail light. One common issue is that the lower part of the taillight does not light up. This issue can be frustrating because there is no light bulb that you could just change. Furthermore, the…
