Greenhouse Motorized Water Diverter and Humidity Controller Circuit
In one of the previous posts I have explained the making of a greenhouse temperature controller circuit, here we study how the effects may be enhanced through an automatic water valve actuator and humidity controller circuits. The idea was originally requested by Mr. Leandros Komninos Technical Specifications Found one on ebay, these are the detail […]
Incubator Reverse Forward Motor Controller Circuit
In this post I have explained a reverse forward timer circuit for operating an incubator motor mechanism with a preferred set of movements. The idea was requested by Mr. Anwar Technical Specifications I am from Indonesia….. I Need Schematics For Incubator Timer with High Torque Motor (DC Motor Power Window in Car). I am trying […]
Simple Gate Open/Close Controller Circuit
The simple gate open and close controller circuit is designed to operate the gate through a couple of push buttons manually, it can be also modified for implementing the activation through a remote control. How it Works Referring to the shown, simple gate open, close controller circuit below, we can witness a rather straightforward configuration, […]
High Current Sensorless BLDC Motor Controller using Back EMF
In this post I have explained a high current sensorless BLDC motor controller circuit which does not depend on hall effect sensors for initiating the operations rather utilizes the back EMF from the motor for the sequential input Overview For proper commutation most 3-phase BLDC driver circuits rely either on a sensor based feedback or […]
RPM Controller Circuit for Diesel Generators
In this post I have explained a diesel generator RPM controller circuit for boats using PWM technique and also using a simple triac shunt circuit. The idea was requested by Mr. Dave. Circuit Objectives and Requirements I have been looking with interest at your electronic circuits web site and would appreciate it you could comment […]
