Scan Module - NOR

This module can be used to scan a 4x4 area to detect a specific object shape. This version uses NOR gates initially. See "Scan Module - AND" for one that initially uses AND gates.

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

With nothing detected by the scanners, the final logic gate (rear bottom) will be true / on. Place your desired scan object in front of the scanners, then move to the back. Change all of the gates that are off to AND gates so they light up. When all gates are lit, the final gate at the back should be lit. Attach it to whatever you want.

Use as a module. Weld several next to each other for larger scans, or weld them facing different directions for 2D or 3D scans. Use additional AND gates to combine into a final scan result.

Also see the "4D Scan Lock" on the workshop.
