I don't have too many sites to go to for circuit or PCB design. For circuit design, go on Google or this forum. For PCB design, I just go to David's PCB Design Tutorial. I got some theory down from university, but for review I go to Google, textbooks or Electronics Tutorials. Sadly, I don't have a place to go for news. Maybe I'd see something new on my YouTube feed. I kind-of started going to this forum for news.
How about your places for this? What's the best websites for circuit and PCB news and advice?
