PCB’s: CNC DIY or China express?

Around three years ago I made a couple of these WS2812b “bulbs” for my hallway. I had a CNC and thought it couldn’t be that hard to etch out some traces. It could. I had so many failures because of leveling issues and pieces of copper getting stuck where they shouldn’t. On the positive side though – they all worked flawlessly for three years. I think they took about an hour to make on average.

What I meant to say was: Don’t waste your time. I could’ve had these made for 50 cents each but instead I wasted my time. Lesson learned šŸ™‚
