In this post I have explained a circuit that will switch off a group of lamps in sequence with a predetermined delay rate, as set by the user through a built in pot. The ideas was requested by Mr. Azam Jamal Technical Specifications I want to make a circuit which works like: I have 9nos […]
Newly Updated Circuit Projects:
Capacitor Based LED Tubelight Using 1 Watt LEDs
In this post I have explained the construction of a homemade 100 watt capacitive tubelight circuit using 1 watt LEDs. The idea was requested, constructed, tested and verified by one the avid readers of this blog Mr. Tamam. Let’s go through the entire discussion. Discussing the Proposed The Design I regularly visit your blog, and […]
Single IC Dimmable Ballast Circuit
In this post I have explained a simple 25 to 36 watt ballast circuit which can used for all fluorescent tube applications within the allocated range. The circuit of the proposed electronic fluorescent ballast may be understood through the following discussion: The Preheater Stage The half-bridge stage comprising the two mosfets are triggered by the […]
Greatest Myths about LED Lighting
LED lighting products are relatively new for the commercial market and as with any new product, they have to deal with doubt and negative comments from consumers’ side. There just is a lot of false information about LED lights that creates many misconceptions about them. So here are the greatest myths about LED lamps and […]
Corona Effect Generator Circuit
In this post we study regarding what is corona effect and how to make a corona effect generator circuit at home using a CDI coil and a tesla coil configuration. Then idea was suggested by Mr. Sanjoy Corona Treatment for Paper Coating Many many thanks for posting the alternate switching timer circuit as requested. Although […]
How to Make Car LED Bulb Circuit
Typically all car turn signal lamps are around 12 to 20 watt rated which are traditionally incandescent bulb types and produce much lower light intensities compared to LED lights. Here I have explained how these lamps can be replaced with high efficiency, high intensity car LED bulbs. LED Car Bulb Design The image below shows […]
