High Wattage Brushless Motor Controller Circuit
This versatile Brushless (BLDC) motor controller IC is featured to control any desired high voltage, high current, hall effect sensor equipped 3-phase BLDC motor with extreme accuracy and safety. I have explained the details in depth. Using the IC MC33035 The “hero” of the circuit is the single chip controller MC33035 which is a high […]
Generate Electricity from Regenerative Braking System for Vehicles
Whenever brakes are applied in any vehicle, a lot of energy is wasted in the process of stopping the vehicle mass and again restoring the mass back to its original speed. The simple idea designed by me appears to be quite effective in solving this issue. I have explained more about this simple regenerative braking […]
Battery Health Checker Circuit for Testing Battery Condition and Backup
In this article I have explained a simple battery health checker circuit which uses ordinary components for enabling the user to get an instant reading of the battery efficiency or regarding its effective discharge rate. The idea was requested by Mr. Shrishail. Circuit Objectives and Requirements I need a circuit of a battery checker. It […]
Analogue Water Flow Sensor/Meter Circuit – Check Water Flow Rate
In this post I have explained a simple water flow meter/sensor circuit using hall effect sensor and a pulse counter circuit. Referring to the diagram shown below, we can see an arrangement consisting of a circular enclosure having a couple of pipes drilled in and a circular turbine shaped wheel installed inside the enclosure. How […]
Adding a PWM Multi-spark to Automobile Ignition Circuit
The post investigates a simple 2 pin oscillator circuit which may be inserted between the pickup coil and the CDI unit of a vehicle for achieving an induced multi trigger input in response to each signal from the pickup coil coil, this in turn is expected to enhance the sparking ability of the CDI coil.
