Introduction: 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!
Step 1: Watch the Video!
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.
Step 2: Order Your Components!

Step 3: Build the Circuit!
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.
Step 4: Upload the Code!
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:
