I was checking out funwithbonus.com today which is a great website by an excellent tournament pinball played named Steve Bowden.  He recently featured a video of Steve Ritchie doing an hour long presentation at NWPAS about the creation of his Star Trek pinball machine for Stern.

When I looked at youtube, I saw that the poster had posted a number of other cool videos from NWPAS 2014, and some from previous years, which you can check out here.
