“Smart” lithium-ion battery would warn users if it is going to ignite
Posted on: 16 Mar 2023
There have been numerous cases of lithium-ion batteries catching fire in everything from mobile phones and laptops to cars and airplanes. While the odds of this occurring are low, the fact that hundreds of millions of lithium-ion batteries are produced and sold every year means the risk is still very real. Researchers at Stanford University […]

Capacitance Meter
Posted on: 13 Mar 2023
Capacitors are vital components in electronics, but sometimes they are broken, or the value printed on the cap has become unreadable. Because my multi-meter does not have a capacitance measurement, I decided to make one!The principle of measuring capacitance is quite simple. The voltage of a capacitor charging through a resistor increases with time T. […]
