We've got the old pdf file of the layout for my dummy load, as requested on Youtube. I've noted an error. The resistor values are wrong, left to right they should be: 8 4 2 4 4 (ohms each).

Basically, you have the right two in parallel, which creates 2 ohms, then the next is 2 ohms and with the previous creates 4 ohms, then you add in another 4 and get 8, and finally another 8 gives you 16 (it's in reverse order to what I'm explaining, rightmost to left)
