In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a … ...

This project demonstrates a simple yet adaptive laser communication system built using Arduino. It was developed as part of a final assignment for a Telecommunications course. 📡 Main Goal: Transmit ...

Abstract: In this paper we present an optoelectronic architecture based on a current-mode photodiode bridge readout circuit that performs differential measurements of the energy variations of ...
