When I was in the preliminary stages of bridge design, I also had repeated failures. I had circuits blowing up. I had circuits just not working, no matter what. I’ve written on my blog about one such experience of mine. You can read it here: http://electel.blogspot.com/2016/10/magic-of-knowledge.html In this article, I’ll talk about the first things you should do if your attempts at designing a bridge circuit have gone up in smoke or if you’re designing a bridge circuit and want to ensure everything has been done properly. Another thing I should mention...
