In this post I have explained about strain gauge based load cell. We will be exploring what Strain Gauge is, what Load Cell is, temperature effect on strain gauge, temperature compensation with Wheatstone bridge and Load cell amplifier HX711, and finally I have explained how to build an Arduino based weighing scale machine by implementing […]
Newly Updated Circuit Projects:
Buck Converter Circuit Using Arduino
In this project we are going to step down 12 V DC to any DC value between 2 and 11 V. The circuit which steps down the DC voltage is known as buck converter. The output voltage or step down voltage needed is controlled using a potentiometer connected to Arduino. By Ankit Negi INTRODUCTION TO […]
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 […]
Simple Capacitive Discharge Ignition (CDI) Circuit
In this post I have explained the circuit for a simple, universal capacitive discharge ignition circuit or a CDI circuit using a standard ignition coil and a solid state SCR based circuit. For an audio/video explanation, you can watch the following video representation: How Ignition System in Vehicles Work The ignition process in any vehicle […]
High Current Li-Ion Battery Charger Circuit
In this post I have explained a high current Li-Ion battery charger circuit which can be used for charging any high current, such as 2S3P, 3S2P battery packs. It can be also used for charging other similar high Ah rated Li-ion battery from a car or a truck battery. The idea was requested by Mr. […]
How a Relay Works – How to Connect N/O, N/C Pins
An electrical relay consists of a electromagnet and a spring loaded changeover contacts. When the electromagnet is switched ON/OFF with a DC supply, the spring loaded mechanism is corresponding pulled and released by this electromagnet, enabling a changeover across the end terminals of these contacts. An external electrical load connected across these contacts are subsequently […]
