A summary of the basics of what is a Zener diode, how they can be used to provide a stable reference voltage, some simple Zener diode circuits and Zener diode markings.
Tutorial, information overview of the basics of the zener voltage regulator circuits and the way in which a zener diode can be used to provide a reference voltage in an electronics power supply.
This circuit is designed to detect very weak light pulses lasting 1uS. It uses a tuned LC feedback network to provide high sensitivity while giving high ambient light immunity. A post voltage amplifier is included with a gain of about X20. The circuit is described in more detail in the receiver section of my Handbook of Optical Through the Air Communications. Note: The LF357 op amp is no longer available, this circuit is for reference only........
Descriptio Normally home appliances are controlled by means of switches, sensors, etc. However, physical contact with switches may be dangerous if there is any shorting. The circuit described here requires no physical contact for operating the appliance. You just need to move your hand between the infrared LED (D2) and the phototransistor (Q1). The infrared rays transmitted by D2 is detected by the phototransistor to activate the hidden lock, flush system, hand dryer or else. This circuit is ver.......
