4D Scan Lock

This lock uses a 3D moving object "key" to open a door (time is the 4th dimension).

Created by Steve's Makerspace. See video about it here:

1) Weld the structure to a block on the ground.
2) Go up to the scanner area. You'll notice the door is glitchy. This will go away after the first use.
3) The key is in the center of the scanner area, secured by two green blocks. Delete these two green blocks to free the key.
4) The scanner will scan from 3 directions, then the key will change shape, and then a second scan will occur using 3 more banks of scanners. If the two scans are positive within a few seconds of each other, then the door will open.
5) The scanner located on the key has to start in the off position, so if the scanner light is lit, pass your body in front of it to turn it off.
6) If you want to change the key shape, you'll need to change the initial logic gates behind the scanners to either AND or NOR to get them to light up. You want to have all the gates lit when your key is in the correct position.

It's a bit hard to explain here. Best to watch my video.

The 2x2x2 module next to the door is by kAN Gaming - "Control Block with Timer" available on the workshop. Visit his channel here:
