In this article I have explained a few simple infrared TV remote controlled fan regulator or dimmer circuits using ordinary parts such as a 4017 IC and a 555 IC. The first concept uses a standard MOSFET based SSR for controlling the fan load and for easy and clean PWM signal operation from the IC […]

PIR Ceiling Fan Controller Circuit
In this post I have explained a simple automatic PIR controlled ceiling fan circuit for school college use, which responds and switches ON only in the presence of a human (students) in the classroom. The idea was requested by Mr. Souren Bhattacharya. Technical Specifications I am, souren bhattacharya, a high school teacher in west bengal. […]
Ceiling LED Lamp Driver Circuit
Nowadays the CFL and fluorescent lamps are almost completely replaced with LED lamps, which are mostly in the form of circular or square shaped flat ceiling mounted LED lamps. These lamps beautifully merge with the flat ceiling surface of our homes, offices or shops providing an aesthetic look for the lights, along with a high […]
BLDC Ceiling Fan Circuit for Power Saving
Within the next few years we may find all conventional capacitor-start type of ceiling fans getting replaced with BLDC ceiling fan circuits, since the concept allows the operation to be extremely efficient and save power by more than 50%. Replacing Capacitor Start Fan with BLDC Fan Just as the traditional incandescent lamps today are almost […]
Simple Ceiling Fan Regulator Circuit
A simple electronic ceiling fan regulator circuit using a triac and a diac is a common type of circuit which is used to control the speed of a ceiling fan. This circuit basically works using phase control principle, in which the voltage supplied to the fan motor is varied by controlling the firing angle of […]
