/diy/ - Do It Yourself

I have all the requisite tools needed to get into electronics, a decent solder station, desoldering pump/braid, good solder and flux, a nice multimeter, boxes of wire, etc, but I've only ever used it for the repair side of things, so I've never really learned anything. I've got an idea for a small project, I'm just curious if it's one I gotta go deep down the rabbit hole for, or if it's a good simple first project. I just want a small light-up 3 digit display, maybe 1-1.5" wide, with 3 small dials or sets of buttons to let you adjust each number up or down, using whatever battery isn't going to make me regret choosing that battery. Something that'll last decently long and then not be too spendy to replace, because I want to make a few sets of these, at least 20.

Is this something where to do it well, it's actually going to take some learnins, or are you all reading thing and thinking "You can do it well by just getting a 10 position dial, a cheap display, a AAA sled, and a 1.5v->3v converter thing you fucking retard"?
