Works first time?
How many of you, that aren't professionals (!) in circuit and PCB design, have managed to do your "thing", got the PCB manufactured (with or without doing the soldering yourself), and it worked the first time!?
Was it luck, or what did you do to maximise your chances of it working??
I'm now in that position myself. I'm not completely useless, I was pretty good at it "once". As in, thirty plus years ago, with designs WAAAAY smaller and simpler 😄. But I had a fair understanding of electronics, component, how they work and what makes them work together. Fair. At best 😄 😄.
My design is now ready to be manufactured. I've run it through an AI for review *several* times (and it have absolutely found stuff that would have made it into a smoke machine! 😄). But AIs can't be trusted, I know that. Not yet anyway! One day, absolutely, but I do not believe that day is today.. 😄
A PCB is cheap enough to get manufactured, components not so much (almost 15 times the cost of the PCB! 😄), and spending time to do the soldering (or unsoldering! 😄) myself is somewhat easy (have the right tools, and the knowledge, although not the experience 😄). But that first power-on IS going to be .. interesting 😃.
Can't afford a professional to take a look (in the thousands of dollars I've heard), don't have any (close) friend(s) that can do it for free, and I've tried getting through here and elsewhere, but didn't get much interest in it.
What else can I do, besides hoping for luck!? Solder on only "relevant" components, check with a multimeter that everything looks ok (no shorts, the right power in the right place).. What else?
