Thanks bryan, very illustative clip, i have to admit...i knew that scopes grounding can cause issues, but this clip told it all and i had also no cluea about USB cable crounding either....luckily i havent blown myself up
This is a great video. I watched it when it was first out but it was worth another viewing to remind me. I did some work on an audio mixer recently and didn't check whether the ground point I used was earth referenced.. oops.
It is one of the few where Dave doesn't ramble too much..
