Video showing the Testing of TSOP1738 with 38 kHz Frequency The TSOP17XX series of ICs are infrared sensor devices designed for sensing infrared frequencies only with a specific range of modulated frequency, and interpreting them into a proportionate magnitude of electrical pulses at the output. This is specifically done to make the sensor immune to […]

Lamp Outage Detector Circuit for Car Turn Signal
The O.E.M. turn signal flashing units installed in automobiles have two basic functions i.e. Flasher and Lamp outage detection. These flashers are usually built with an 8-pin IC like U2044B, U6432B etc. which are specifically made for automotive flashers. Designed and Written By Abu-Hafss Circuit Operation These flashers normally oscillate at about 1.4Hz. When a […]
Washing Machine Motor Agitator Timer Circuit
The article details a circuit design for controlling a washing machine motor agitator through a preset time sequence which also includes an alternate reversing of the motor rotation. The circuit was requested by Mr. E.Rama Murthy. Technical Specifications I am having old washing machine which is good working till now. Of late, its PCB has […]
Single Phase Voltage from Three Phase Voltage Source
In this post I have explained a simple relay changeover circuit for extracting single phase AC from a three phase AC source irrespective of the condition whether all the three phases are present or not. The circuit was requested by Mr. Biannz. Technical Specifications hi sir please i need something I’ve been searching everywhere but not avail […]
Making a Flynn Motor
The post provides an in-depth description of the Flynn motor circuit concept and furnishes the rough replication details for the same. Parallel Path Concept In one of my previous posts we got a comprehensive view regarding what’s populary known as the parallel path magnetic theory In this theory a relatively weaker electromagnetic assistance is used […]
Ultraviolet (UV) Sanitizer Circuit for Disinfecting Home Materials
In this post I have explained the making of a simple, cheap yet effective ultraviolet or UV-C home sanitizer circuit using ultra violet rays or UV-C. The idea was requested by Mr. Shah (kristin). Using UV Rays against Coronavirus The UV-C sanitizer circuit I have explained below can be effectively applied for sanitizing all external […]
