How to Build a 220V DC Inverter UPS Circuit
In this post I have explained a simple 220 V to 220V DC online UPS inverter circuit. The idea was requested by Mr. Taiye. Technical Specifications I intend to build a 1000 watt UPS with a different concept (inverter with high voltage input dc). I will use a battery bank of 18 to 20 sealed […]
How to Build a Microphone Amplifier Circuit
In this article we are going to see how to build a microphone amplifier circuit with operational amplifier LM324. This circuit can be used as good pre-amplifier for audio projects. Selecting an Opamp The heart of the mic amplifier circuit is an op-amp LM324 which is quad op-amp moulded in single IC. We are going […]
How to Build a Rain Sensor Circuit
This is a simple rain sensor circuit which can be built by a school grade student very easily and can be used for displaying its relatively useful feature, probably among his friends or in a science fair exhibition. Using IC 555 as the Comparator The circuit is basically rigged using IC 555 as a comparator […]
