Dr, Stiffler will not make such a comment until he can float the system, with zero input. As I stated, and the video demonstrates, the signal can be disconnected now after startup, but not both the ground and the signal. Certainly it is true that I am being optimistic in the belief that there is no ground looping involved, as that is rare in my experience -- but admittedly, not impossible, so I cannot blame you and Steven for the apprehension. All I can say is give some time here - Dr Stiffler is basically a one-man show, and does not have a staff. I consider him to be extremely generous for sharing this information at what may be an early stage. Obviously he does not think ground looping is involved either and the experiment is progressing rapidly in the number of LEDs which are driven. Remember also that the "signal" is no more than a few milliwatts at best and that when it is used, a resistor between the device and ground is howing something like half a watt. Eventually - IF nothing else happens first - it will be possible to focus the light from these LEDs onto an efficient photocell, and thereby eliminate ground. That is what will silence all possible doubt. I think I mentioned all of this before in various scattered postings, so why the insinuations? ... My advice - is to wait-and-see, unless you can add something positive into the mix. Jones
