Transistor Monostable Circuits with Applications
In this post I have explained how to build a few simple monostable circuits using only transistors, and also learn how to make practical application circuits with them. If you search for transistor monostable circuit online, you will find that one typical circuit has been discussed in all the online articles. This circuit looks a […]
Basic Op Amp Circuits and Projects
In the following article I have explained op amp basic application circuits and projects, with equations, for solving their specific component values. Op-amps (operational amplifiers) are a specialized type of integrated circuit that include a directly-coupled, high-gain amplifier with an overall response characteristics adjusted by a feedback. The op-amp derives its name from the fact […]
Electronic Measuring Tape Circuit using Ultrasound
Everyone is familiar with the mechanical measuring tape made of wood to measure human height. We offer you an original electronic version that operates based on the use of ultrasound. The circuit can be also used to measure distances between two surfaces or walls. Basic Working Ultrasounds are part of the range of sounds that […]
Battery Low Voltage Alarm Circuit
Despite its simplicity, the Battery Low Voltage Alarm circuit has a very important function. It forewarns you of approaching battery failure so that you may run to the store and get replacement cells before your equipment stops functioning entirely. Because of its compact size and low current need, it may be integrated into the devices […]
Transformerless Automatic Night Lamp Circuit
This transformerless solid-state automatic night lamp operates without using bulky transformer, and automatically switches ON some LEDs during night, and switches them OFF during day. In this post I have explained how to make a transformerless automatic darkness activated LED lamp circuit, using a couple of transistors and capacitive based power supply, eliminating the use […]
