    • Hi, must have missed #202. Really nice and tidy place but their largest chamber seams smaller then the one I am doing test in this week. However that had a really nice door. Sadly I can’t send you any pictures, testing next generation of Articulated haulers and Wheel loader.

      Great Video Dave,
      As usual, very helpful and informative. Question on your ground plane, was that somehow connected hardwired to “earth ground” or was it through the contact with your ESD mat?

      Thanks!

      • It was hard wired to mains earth.
