Someone please talk some sense into me. I'm putting way too much thought into a Rigol DP832 bench power supply that I probably don't need. For a hobbyist level person, is there any reason why I should or should not have this? How about if I ignore the price? I have a degree in computer engineering, but I've worked 99% in software my entire professional career (the last almost 20 years) and I'm trying to re-learn the hardware side for fun, and to make a few bucks creating widgets as a fun side job. Lower voltage stuff; arduinos, stepper motors, radios, etc.. fun stuff. As I get back into it, are there any real reasons that I would be more productive with this type of power supply, vs. a simple one knob adjustable voltage power supply? I realize it's more convenient than having to use a couple DMM's to measure power, but any other reasons?
