Make this EV Battery Charger Circuit
In this post I will explain how to build and test a homemade yet very professional looking high power EV battery charger circuit using H-bridge fixed-frequency AC inverter topology, driving a series-resonant LC tank. Let us go through the step by step working of the circuit stages and other important details: Transmitter Circuit Diagram The […]
GSM Car Ignition and Central Lock Circuit Using Arduino
In this post I will show how to construct a GSM based car security system using Arduino, which can lock and unlock car’s ignition system and central lock by sending a password SMS to car from your cellphone Car theft can be a heart break; it feels like your loved one got kidnapped. It hurts […]
Car Reverse Parking Sensor Circuit with Alarm
In this post I will show how to construct a car reverse parking sensor alarm circuit using arduino, ultrasonic sensor and 2.4 GHz transceiver module. This project can be add-on feature for your car if it doesn’t sport a build-in parking sensors. Introduction The proposed project has similar functionality as traditional car parking sensor has, […]
How to Make HHO Fuel Cell Circuit in Automobiles for better Fuel Efficiency
In this post we’ll try to investigate the making of HHO gas in automobiles for enhancing their mileage by approximately 50% or more, that means a reduction of petrol or diesel consumption by the same amount. In the previous post I tried to put forth an innovative design of a high voltage low current generator […]
CDI Tester Circuit for Automobiles
The first design below shows a simple workbench setup for testing all types CDI circuits. It uses a capacitive discharge ignition circuit along with a CDI coil to implement the testing procedure. Audio/Video Representation The circuit does not require any separate oscillator, rather the 100Hz from the bridge rectifier itself works like a pulsed trigger […]
