Thanks for the info. I tried but the in-circuit resistance stays at 0.97K, no matter how many HB lines I make. So there was no difference in hashing either....
Did you need to remove any coating from the resistor? (I don't think that they would apply conformal coating to a USB miner).
Cheers
nope, I did not remove any coating. I didnt draw lines, more like a child coloring in, scribble style :-)
