A half-decent soldering iron is way better than a super cheap soldering iron.
-
Plan the build as much as you can, and then order all the parts at once. This way you’re not tied up waiting for parts to ship which kills momentum.
-
Wires take up more space in an enclosure than you think.
-
If you can order 3 of something for not much more money than 1. Do it. It’ll allow you to build up stock of things you use. That way when you get an idea, you’ll have parts on hand.
-
Allow yourself to fail. Some ideas sound good but aren’t. It’s ok to abandon a project.
-
Lean on the community. If you have an idea for a project, someone’s probably done it before. Look it up, see how they did it, learn from their mistakes. You can stand on the shoulders of giants and you absolutely should.
Not to discourage you but that is a super ambitious first project. If you want a good audio player but don’t want to spend a ton, I have the fiio snowsky echo. It’s super affordable, but surprisingly powerful. It drives my 250 ohm headphones without issue. No way you’re DIY’ing anything that good for its price. However if you want to DIY a music player just because you want to, absolutely go for it!
