I'm crazy passionate about electronics, hopefully soon you will be too!
My videos tend to focus on power electronics (the best type of electronics), and my goal is to get as many people as possible excited to learn about this fascinating subject through fun analogies, demonstrations and stories! Don't be afraid to ask questions in the comments, the only thing I love more than answering questions is asking them myself ;)
