    Interesting! If electron drift is only .0000000001% of the speed of light then it takes 3.5 + minutes for a charge to transit a one foot long wire? That accounts for my slow signals!

    Ooops! Slip of the calculator! Just under a millisecond. But still much much too slow. Nearly a second for a thousand foot wire.

    Individual electrons take a surprisingly long time to move through wire (they are VERY small!)
