We are going to show how to recycle free 18650 Li-ion battery from electronic waste. Our experience using it for almost a year, it runs well. Read more
Learn types of rectifier circuit using op-amp. A diodes cannot rectifier ACV lower mV. But 741 rectifiers can help it, in filters, signal measurements, etc. Read more
we ordered from PCBway.com for the first time. The ordering systems are great and easy, even for my kids and me, who are relatively new to online ordering. Read more
Let’s use TL431 circuit instead Zener. It’s shunt regulator with high efficient, easily uses, cheap. Often, found in common circuits. Read more
