Quick tip: Stopping wobble and vibration on HS1177

I was having an issue with my fpv video getting really wobbly when I was at >50% throttle.  I went over my quad multiple times trying to figure out what was causing the vibration.  The camera seemed fine, all the motors were balanced, and I even tried new props multiple times.

It turns out the HS1177 board doesn't always sit nice and snug.  I've heard of people putting all sorts of thin object to get the slop out and stop vibration.  Here is what I did

After that I just sandwiched it all in there and no more vibration!  I should probably cut down the foam a little so I don't cover up the vent holes on the back.
