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 […]
Newly Updated Circuit Projects:
Windshield Washer Fluid Indicator Circuit
In this article I have explained a permanent indicator of the windshield washer fluid level. Knowing that electronics do not mix well with liquids, instead of using a float gauge system, we have devised a completely different operating principle for you. The operation of our circuit is based on timing the duration of the motor’s […]
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 […]
Simple Motorcycle Security Alarm Circuit
In this article I have explained a simple motorcycle ant-theft security alarm circuit using a tilt switch and a TTP223 touch switch. The circuit was requested by Mr. Sergei, as given below. Design Request and Specifications I am a motorcyclist and I would like to ask you to design a simple and cheap alarm system […]
Automotive Sensor Monitor Circuit Diagram
This fascinating Automotive Sensor Monitor Circuit was created and shared with me for publication by a devoted reader of this blog and passionate electronics enthusiast, Mr. August Peterson. I sincerely appreciate Mr. August’s valuable and generous contribution to this site. Overview Automotive diagnostic code readers are invaluable in displaying what the vehicle electronic control unit […]
Traffic Light Controller Circuit [Signal Red, Green, Amber]
A traffic light controller circuit can be used for controlling the sequential illumination of the RED, ORANGE and GREEN traffic signal lamps, by maintaining appropriate delays between the illumination sequence. In real traffic signal light system we all have seen how the red, orange and green lamps switch ON/OFF in sequence with specific amount of […]
