DIY Boost Converter || How to Step Up DC Voltage Efficiently

In this project I will show you an efficient and common way how to step up DC voltages. I will also demonstrate how easy it can be to build a boost converter with the help of an ATtiny85. Let's get started!

The video gives you all the information you need to create your own boost converter. The next steps just contain additional information for your convenience.

Here is a list of all the parts that you need with example sellers (affiliate links):

Here you can find the schematic for the project and reference pictures. The soldering process takes around 45 minutes if you know what you are doing.

In order to upload the code to the ATtiny85 you can use an Arduino Uno. Here is an older video of mine in which I demonstrated how to do that:

You did it! You just created your own Boost Converter!
