View all the photos and files before starting this project. I have numerous 18-volt laptop power supplies that I've accumulated over time, and I wanted a versatile supply that would fit neatly in my tool box. I found inspiration here at around 21:00 to remove the Trimmer Pot https://www.youtube.com/watch?v=C3zbZq7uO30&t=440s PARTS LIST Before you begin, check your part boxes! I'm sure you can find these items cheaper.
