How to Make a Battery Protection Circuit (over-discharge protection)

Powering homemade projects with rechargeable batteries is actually more difficult than it sounds. This is because most battery types cannot be over-discharged, as doing so may damage the battery and make it unstable. Consumer electronics overcome this issue by using clever battery protection circuitry that constantly monitors the battery’s voltage, automatically switching the device off […]

Use Arduino to Switch Power On and Off!

Welcome to DIY Tryin. Build something new. I’m Patrick Norton. I’m Michael Hand. We were going to bring you the most amazing confluence of aluminum gas welding and lemons today. But that failed horribly. Yes. Yes, it did. So instead, Arduinos. Yay! What’s an Arduino? So Arduino is a microcontroller that you can program to […]

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 […]
