content: I'm not cool. This is a total waste of time, lol. And I bet he never got it fully debugged and working. This is one of those things that after you're done soldering, you wait for a day or two while mentally preparing yourself for the disappointment, because you're 99% sure it isn't going to work on the first try. I can and have done stuff like this in a pinch, and I'm fully capable to make it as purdy. But it is still a waste of time.Not to mention that vero/enamel wire is idiotic. Bare bus wires would do for 99% of that. No insulation to melt off and fiddle with. With short sections of wire, 30 AWG might as well be tree trunks and can be easily routed to not short simply using air gaps (plus or minus kapton tape). He took 40 hours to carefully route this wires, anyway, so he could have saved 30 hours of melting insulation away and getting easier connections using tinned or silver plated copper bus wire.It's irritating that he uses a conical tip for this. If you do stuff like this get a Hakko and buy a CF1. Thank me, later. You will use it the same way, but you won't have to fidget to the get solder bead where you need it, it will be skinnier/sharper and unidirectional, so you can get the connections on there without playing as much musical chairs, and you'll have a much longer working time between picking up solder on the tip and getting the connection made before the solder dries out.

content: This is from a time when it was very expensive to run prototype boards (1997). Back then this was a reasonable alternative:http://elm-chan.org/docs/wire/wiring_e.html

The mechanical, soldering and wiring accuracy level expected was at the level shown in the video, plus decent sheet metal fabrication skills, usually with aluminum.The video shows the use of polyurethane covered enamel wire which is a breeze to use as the insulation melts back easily with a soldering iron tip and solder blob, exactly what we used in 1974.Another poster here doubted the assembly would work but I don't have any doubts that it worked fine first time, and is probably still working somewhere till this day. Not shown was the circuit diagram the technician was probably working from or the red texta pen (sharpie) he used to outline each connection after it was completed.Sure times and methods have changed over the years, but the method shown in the video can be used today, to make up a project needed *right now* ... providing one has the skills and experience.Any senior electronics technician can do this kind of work, anytime.Here is a picture of a STM32F051 32QFN deadbug I made up by hand about two years ago, aged 62. It was then flashed with Forth and worked first time. Sadly I didn't have any of the necessary poly covered enamel wire so I had to use chunky wirewrap wire stripped of the plastic coating. It looks pretty ugly, and it is, but I made it in a few hours and was using it that day. It still works fine.http://hightechdoc.net/misc/stm32F051-deadbug-angle.jpg
