This simple automotive electrical fault finder probe circuit will enable you to solve most electrical troubleshooting in your cars, tempos, motorcycles etc with a lot of ease and in a hassle free manner. The idea is very simple. The circuit exploits the high impedance gate value of the MOSFET which makes the circuit extremely sensitive […]
Newly Updated Circuit Projects:
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 […]
Vehicle Parking Lot Counter Circuit
In this post I have explained how to construct a vehicle counter circuit that can count the number of vehicles entered in a parking lot at office building, schools, libraries, restaurants, hotels etc. The proposed project can count up to 999 vehicles especially cars and two wheelers and it can even count long vehicles like […]
Automotive Display LED-backlight Driver Circuit using LP8864-Q1
The LP8864-Q1 is this cool automotive high-efficiency LED driver that comes with a boost controller. Basically it is made to efficiently power the LEDs in your car. It has got these four high-precision current sinks that do something called phase shifting. What is neat is that this phase shifting automatically adjusts based on how many […]
Vehicle Body Metal Detector Circuit
The main objective we are trying to achieve with this vehicle body metal detector is that only an automobile can trigger the opening of the gate. The solution involving the interruption of a light beam is not suitable, so we turned to a metal detector, as metal is a primary material in any automobile. In […]
Check What’s Behind the Paint of a Used Car
Some methods to hide a used car’s external deterioration include filling up rust holes, removing collision dents with putty, fiberglass, or epoxy, and painting the car. The outside condition of an automobile is very important to potential used car purchasers due to the high cost of extensive bodywork restoration. Here is a simple circuit concept […]
