SMDs don't agree with me: pcb that did not work

Video Description

I wanted a very simple PCB to test various throughole and SMD LEDs, LEDs in series to dial in the series resister to get to desired light intensity. What I did not know, that you cannot just drop SMD LEDs on SMD footprints and expect them to conduct properly. Well, you learn every day.
