Building a PIN Diode Geiger Counter
https://www.electronics-lab.com/building-pin-diode-geiger-counter/
“Kai” is in the process of building a Geiger counter based on BPW34 photodiode and explains his first step for the sensor circuit. The common approach to protect the photodiodes from light is to use one layer of tin foil and connect it to ground. This should also protect the circuit against electromagnetic radiation. I’ve started with something […]

LED-based time-of-flight IC for object detection and distance measurement
https://www.electronics-lab.com/led-based-time-of-flight-ic-for-object-detection-and-distance-measurement/
by Lee Goldberg @ edn.com: Although Intersil’s ISL29501 time-of-flight (ToF) signal processing IC doesn’t have anything to do with the lighting applications I normally cover, I felt compelled to bring it to your attention because it’s one of the most innovative LED applications I’ve seen this year. The device requires little more than an external emitter (LED […]
