Rain Triggered Instant Start Windshield Wiper Timer Circuit
The following circuit was requested by one of the readers of this blog Mr. Keval. The actual request was for a rain triggered windshield wiper circuit, but the idea here has been further enhanced with a quick start feature for better efficiency. How Conventional Wiper Systems Work Normally, electronic wiper control circuit involve a bistable for switching the […]
Simple PIR LED Lamp Circuit
The following PIR LED lamp circuit was designed by me for one of the followers of this blog Mr.Deepak upon his request. The circuit is a LED driver which responds to ambient light as well as to the presence of a human, person or intruder, and varies its illumination accordingly, let’s know more. Technical Specifications “I was looking to […]
Easiest Single Axis Solar Tracker System
In this post I have explained how to make a very easy solar tracker circuit using a predetermined algorithm through a 555 IC timer circuit. Introduction In this site I have already published a solar tracker system circuit which is intended for automatically adjusting the solar panel face such that it stays perpendicular to the incident sun rays at […]
Digital Clock Synchronized Programmable Timer Circuit
I have already discussed one programmable timer circuit in this blog earlier, the circuit involves the IC 4060 for generating the basic oscillations which is further used for generating the required time intervals, however this cannot be synchronized with an external clock. The following circuit was requested by Mr.Amit, here the concept makes use of a clock for acquiring the required base timing […]
Battery Over Charge Protected Emergency Lamp Circuit
The following LED emergency light with battery over charge protection feature circuit was designed by me in response to the request sent by PP. Main Features In this article I have explained an LED emergency light circuit with advanced features such as, over charge battery cut off, day time auto-disable, and need less to say […]
