Seems like we are always the same, the ones that meet on the very corners of true old original youtube creators I am so glad to have known both of your channels gentlemen :)

Thanks, although I would not put myself in the same league as David. He understands what he is doing. My projects tend to be "poke and hope and see what happens." ​@DoNotPushHere
