How to protect circuits from reversed voltage polarity!

In this video I’m going to show you a couple of ways to protect your circuits from backwards power connections. Let’s say you have a 12 volt power source like a battery and you want to power something. It doesn’t matter what it is. Let’s say it draws 2 amperes. When the battery is connected […]

Transistor / MOSFET tutorial

In this tutorial I’m going to go over the basics of a popular transistor and show you how you can use it to control different gadgets. What is a transistor? A transistor is a device that allows you to use small changes in voltage to switch things on and off. They are kind of like […]
