The circuit idea I have I have explained in this article can be used for controlling the intensity of many LEDs through a ceiling fan dimmer switch unit. This circuit was requested by Mr. Joseph who wanted a simple method through which an ordinary home dimmer switch could be integrated with a chain of LEDs for controlling its brightness from […]

AC Light Dimmer Circuit
In this post I have explained through two examples how to build a simple110 V or 220 V AC light dimmer circuit for controlling light intensity with pot, using the principle of triac phase chopping. A 220V dimmer switch circuit is basically a triac/diac based AC mains voltage regulator circuit which can be used for […]
3D Moon-Sphere LED Driver with Charger and Dimmer Circuit
In this post I have explained how to build a homemade LED driver with dimmer and charger circuit for illuminating a 3D moon from a 5V USB source. The idea was requested by Mr. John Sweden. Circuit Objectives and Requirements I’ve been a visitor to your website for many years and wonder if I may […]
Underwater LED Boost Converter Circuit with Dimmer
In this post I have explained an LED controller circuit having a boost and dimming facility specifically designed for underwater shooting application. The idea was requested by Mr. Svein. The Circuit Request I came across your blog at https://www.homemade-circuits.com and thought I’d ask you a question regarding building or modifying a LED driver. I planning […]
LED Driver Power Supply Circuit Using Dimmer Switch
In this post I have explained an effective and efficient high current compact LED Driver power supply using a dimmer switch gadget. In one of my other posts I discussed a high voltage transformerless power supply circuit that used a triac for controlling the capacitive output, however since the concept involved shorting the capacitive output […]
Automatic Street Light Dimmer Circuit
In this post I will show how to construct an Arduino automatic street light dimmer circuit, which can reduce its brightness when no vehicle is passing in the road to save power. Overview We will be exploring the methodology of sensing the vehicle or human being without false detection which may occur due to animals […]
