Teach Me PCB
I held off doing PCB stuff for a long time because the tools seemed incredibly complex and intimidating, and now I wonder how I ever did anything without it. The things I wish someone had told me:- all a PCB is, is a flat version of your hand-wired prototype - all those crazy lines are just the wires - there's no special hidden EE magic until later- the schematic editor shows your intent- the pcb layout editor shows where things go- the hard part is actually just finding schematic and layout editor files for the components you're using - github search is great for this- you will make lots of mistakes and need a few goes - everyone does, debugging is half the fun, don't be afraid- online PCB houses make those mistakes cheapThings I have made with little more than introductory-Arduino knowledge:- A wearable bluetooth ring:
