Yeah, for sure if I was perfect I wouldn't make mistakes, but I am not.

However, I have to disagree in one aspect, it is not basic electrical engineering practice to add filter capacitors on every node. Some nodes need it, some don't. This one, by the topology of the circuit didn't, but from the need for immunity did. This is not always obvious, but for sure I could have anticipated.

Hindsight is definitely 20/20 on this one.

Well, you're better than me than. Mistakes like those are @$%#ing expensive, so they have me questioning WTF I'm even employed sometimes. I wasn't the only one looking for the issue so maybe you're right, but it feels really bad.

I know exactly what you mean, I've been there myself so many times that I have learned be humble just for this one reason. I have a post about good engineers being humble which is based on this idea.

If you think this way, you are already on a good path. Think that there's a lot of folks that don't even care at all, you do care and want to improve, that sets you apart.
