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 […]
Newly Updated Circuit Projects:
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 […]
Automatic Food Warmer Lamp for Hotels
In this post I have explained a simple food warmer lamp timer circuit for restaurants and hotels which can be used for automatically switching OFF the lamps after a predetermined time whenever the food under the lamps are idle or in the absence of an interaction under the lamps, thus saving precious electricity. The idea […]
5 KVA to 10 KVA Automatic Voltage Stabilizer – 220 Volts, 120 Volts
Voltage stabilizer in the range of kVAs are powerful AC voltage stabilizer units specially designed for controlling and stabilizing high voltage fluctuations, for high power electrical equipment. In this article I have explained an easy to build a 7 stage high wattage in the order of 5000 to 1000 watts stabilizer circuit which can be […]
