📝 Description of the video: Hello everyone. In this video, I would like to show you how I realized my old idea: creating a laptop power supply from scratch. I advise you to watch this video after watching the first part about the return trip, so there will be more understanding. In this video, I put a lot of emphasis on the clamper, its calculation and selection of components, I hope you find this information useful. And as always, enjoy watching!
