Nexdome Shutter Power Transfer Block

Nexdome has begun shipping a new shutter automation system that relies on power tracks embeded into the rotator track. The power transfer block that they ship is very rudimentary and unreliable. As we know, the observatory dome is not perfectly rounds so it potentially loses contact at certain rotations. This is an attempt to provide a better and more reliable mechanism for that power transfer. It uses compression-spring floating arms and sealed bearings to maintain contact with the track through rotation. While it may not always maintain perfect contact during rotation (though mine seems to do so reliably), when rotation stops, the power contacts should be well placed to power the shutter.
