Beacon Finder

thingiverse

Building a beacon finder from scratch is an ambitious project. The beacon itself will rely on polarized light as its guiding force. Strategically placed holes will serve as homes for Light Dependent Resistors (LDR) sensors, which will be carefully situated to detect variations in intensity. Ahead of each hole lies a strip of polarizing film that carefully aligns with the LDR sensors positioned directly beneath it. Notably, the topmost and bottommost films are oriented 90 degrees apart, creating an unmistakable difference in reading between the pair. As long as there's a polarized light source directly facing one set of sensors, detecting disparities becomes child's play by measuring the contrast in electrical signals flowing through each LDR sensor
