Yeah, I agree. They’ll be able to get things working with AA’s or a 9V, no need for a fancy power supply. If I were them, I might even just pick up a couple of DC power supplies from the thrift store 25 cent bin of assorted cords.
OP, plenty of people donate things like DC power supplies, they are just not adjustable, they are just random chargers and cords they had laying around. You probably already have a couple. You might not be able to produce the 6.176523 V you want right off the bat if you just have a 5V and a 12V power supply, but one of the first things you learn about with analog electronics is voltage dividing, so it’s easy to get what you need.
Also, the kits that come with an arduino or whatever still have the stuff that you’d want. Arduinos are handy, too cause they’ll take analog inputs so you can graph stuff, or do whatever you want with your computer connected to your breadboard.
