For a pro who knew everything on how to do this, I would likely expect little over a week of man-hour work. However the guy looks like he had a great grasp on the modeling aspect, but not so much on the electronics, so I wouldn't be surprised if he spent equivalent of about two-man-hour work weeks on this. For someone like me, it would likely take the full 17 months to produce something like this purely for the modeling portion. I'm actually adept at electronics, but I wouldn't be able to model something like that to save my life.
