In this post we are going to build a drag race timer circuit using a 7 segment display and commonly available discrete components which can measure the time taken for a car or any other vehicle from start line to finish line. The proposed circuit is fully automatic, meaning it can start and stop the […]
Newly Updated Circuit Projects:
Incubator Reverse Forward Motor Controller Circuit
In this post I have explained a reverse forward timer circuit for operating an incubator motor mechanism with a preferred set of movements. The idea was requested by Mr. Anwar Technical Specifications I am from Indonesia….. I Need Schematics For Incubator Timer with High Torque Motor (DC Motor Power Window in Car). I am trying […]
White Noise and Pink Noise Generator Circuit
In this post I have explained how to build a simple white noise generator circuit which can be subsequently filtered to generate the pink noise output. If you hear to the white noise or pink noise, you will find it exactly similar to the noise that we hear in FM radios in the absence of […]
Fuel Cells [How they Work]
Fuel cells have the capacity to be the most effective and ecologically friendly power source ever devised. Since fuel cells are able to generate drinking water as a by-product, they are indeed an appealing replacement for traditional power generation. How much more could you want from a source of energy? History Sir William Grove developed […]
Self Adjusting Automobile Headlamp Circuit
A suddenly dimming and brightening automobile headlamp is usually quite undesirable, since it causes a painful interference with the normal vision of the opposite side driver or the passengers. In this post we try to design a gradually self-adjusting automobile headlamp brightness circuit, which enables the brightness of the vehicle headlamp to vary proportionately in […]
Converting Wasted Spark Ignition to Sequential Spark, for High Efficiency Combustion
In this post I have explained a simple method of converting a wasted spark type ignition system in an automobile, into an enhanced, sequential spark, 6 cylinder engine type ignition system. The idea was requested by Mr. Brenton, as given below: Main Requirements I was looking through the car and motorcycle section but couldn’t find […]
