This post is already pretty old but I ' ll give my two cents . I love the Game Over Gregory Show by Kinda Funny , it ' s my all time favorite podcast , second favorite is Mysterious Universe , <| sep |> It was probably induced voltage . DMMs have very high input impedance so stray voltages without any actual current supplying ability get measured just fine . If you put a load of any kind on it , and it got pulled down to 0 V , you would have known that the case . <| sep |> Daaaaang im so jealous <| sep |> You ' re not , but I certainly don ' t argue the point <| sep |> Pssssssst . Psst . What color is yo shot How ' s life ? <| sep |> I checked out as a guest and used paypal to pay . I didnt have to do anything special <| sep |> I was thinking that if we had a PVC pit we ' d design it with removable sections so we could plan for 8 ', 9 ', 10 ' widths you just never know .
