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 […]
2 Mosquito Swatter Bat Circuit Diagrams Explained
Mosquitoes are a big menace to humankind and these are present in every corner of the world. A cool way of avenging yourself could by eliminating these “devils” through electrocution. A mosquito swatter bat is designed just for this. I have explained how to build its electronic circuitry. The idea was requested by Mr. kathiravan d. […]
Programmable Humidity Controller Circuit
The simple programmable humidity sensor circuit I have explained in this article can be used for controlling or maintaining a suitable level of humidity inside a close premise. The circuit could be used in poultry farms or similar areas where humidity level becomes crucial for keeping the animals healthy. The idea was requested by Mr. […]
1.5 watt Transmitter Circuit Diagram
This little transmitter will allow you to communicate, chat, send music transmission on any standard FM Radio tuned within the existing band, across a radial distance of not less than 500 meters or half a kilometers. Warning: Using this transmitter could be illegal in your country or area, take appropriate permissions before indulging. How it […]
Simple Automatic Plant Watering Circuit for Monitoring Soil Moisture
This automatic plant watering circuit can be used for automatically sensing soil humidity and triggering a water pump when the ground gets parched below a predetermined level (adjustable). Circuit Operation The circuit is rather straightforward and uses a single IC 555 as the main active component.Referring to the automatic plant irrigation circuit shown below we […]
