This year I treated myself to a benchtop power supply for home use.

I've worked with electronics (mostly embedded hardware and lower-level software) for >3 decades professionally where bench supplies are everywhere. My hobby use saw me using various wall-warts, regulators, batteries, and hijacked/hacked-up desktop PSUs as I always thought owning a dedicated supply would be a waste. Purchasing other TE had higher priority.

Surprise!! Life is so much better, unbelievably, having my own benchtop power supply for idiot stuff that I would not have invested the time and effort to try previously. I was adding a fan to a project yesterday so I spent ~2 minutes testing candidates for audible noise when using 12V and 24V at various currents - not a necessary part of the selection process for the expected use but nice when it is low effort (turn on PSU, select output channel,dial in voltage, dial in current, done).
