Trekprops.de has gone so far above and beyond with this prop build, they might as well be on the voyager itself. As you can see in the selected photos below (there’s more on his page), he started with pieces of scrap basically. There’s an APC power switch there and some random bits of plexiglass. It is fascinating to see the thing come together picture by picture.
The screen is static, it is actually just a backlit image. But the really interesting part is how you turn it on. He said he just couldn’t bear the idea of a visible switch on the unit, so he created a remote control for it. He didn’t scrimp on the remote control details either, it looks fantastic on its own!
