The last 2 pictures show jumper wires with one end "cut-off" and the resistor soldered and then heat-shrink covered. This puts 3 resistors 'inline' with the jumper and simplifies quick tests. This can also be done with the zeners, but I evolved the USB small adapter boards shown in the first group of pictures which is the approach I prefer.
