Here's some pictures and a couple of video of the Periscope lifter.
It works and I have plenty of adjustment points to set the Periscope
inside the dome.
The only thing is that Vex servo is loud.
It's not as loud as in the video, But it's still loud.
I'll have to see if I can find a replacement servo and not use the Vex
Anyway, It's still in the works and you can see the Jag dome plate arrived.
