Remember that power supply that failed earlier? I replaced it, and now I’m replacing the replacement. I needed an adjustable power supply to run a motor, you can vary the speed of a dc motor with the applied voltage. So I’m replacing the adjustable supply with a cheaper fixed voltage supply I found in a drawer. It’s also smaller so it fits in a drawer. And it’s actually still adjustable, just over a smaller range, and you need a screwdriver, and there is no screen to tell you the voltage.
