Re: voltage loss over long runs
Or you get a number using 30' and divide by 5 or 10 - you get a better number for the shorter run that way.

Re: voltage loss over long runs
The relationship of the effect on a longer run scales (almost linearly) to a shorter run - not true? Impedance per unit length is a key component of the equation, correct?

Re: voltage loss over long runs
No worries, several different contexts here I reckon - your OP used 3' and 6' as examples thus the 5 and 10 divisor.

Re: voltage loss over long runs
Coming back and reading this thread I can't help but laugh at the fact that 1296 ended up having a tethered bot.

Re: voltage loss over long runs
I get teased about it quite often. ;o)

Re: voltage loss over long runs
With some of the long wire runs we are seeing this year, you may also want to watch out for the weight of your wiring. We have been through multiple cycles of weight reduction and I have concluded that we could have laid out our electronics better and dropped some excess weight. I used a kitchen scale and found that 18 feet of 12AWG wire weighed 0.494 pounds. That was about how much wire we would have needed to add a pair of motors up front for an active intake mechanism.
