Triacs are one of the most important active electronic components which are exclusively used for power switching applications, these devices are especially suited to AC mains loads, and are able to switch large currents consistently. Triacs are the solid state replacements to mechanical relays, and come configured as static relays. The modern triacs today are highly sophisticated […]
Newly Updated Circuit Projects:
Voice/Audio Recorder Playback Circuits
In this article I have explained a single chip circuit which can be used for recording and playing back short voice clips or any audio clip ranging from 20 to 60 seconds. About the IC APR9600 The incorporated IC APR9600 is a programmable voice recorder chip which facilitates infinite number of recording/erase of audio files […]
High Current Transistor TIP36 – Datasheet, Application Note
If you are looking for a power transistor able to support high current upto 25 amps and yet not incorporate the traditional cumbersome TO-3 package, then the TIP36 would certainly impress you. High Current from Smaller Package The package of TIP36 is TO-3P which means the accompanied heatsink would require just a single hole to be drilled and […]
Using a Fan Dimmer for Controlling LED Intensity
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 […]
Mains AC Xenon Tube Flasher Circuit
In this article I have explained a very simple yet amusing mains operated xenon tube flasher circuit using ordinary electronic components. Circuit Operation The circuit was taken from one of the old elektor electronics magazine and it is indeed a very cute little circuit which may be used for creating high intensity lighting effects during […]
3 Watt, 5 Watt LED DC to DC Constant Current Driver Circuit
The following article provides a simple yet very decent solution for driving powerful LEDs rated at 3 watt or 5 watt. Circuit Objective These 3 watt 5 watt and similar high watt LEDs are able to produce highly intense and powerful light outputs, however these are extremely vulnerable too with their operating parameter. I have […]
