How to Illuminate 100 LEDs from 6 Volt Battery
In this article I have explained an innovative way of driving more than a hundred white LEDs from a 6 volt battery. The circuit utilizes the IC 555 for driving a step up transformer, whose output is finally used for illuminating the LEDs. A special PWM configuration makes the circuit much power efficient. Main Stages […]
Making a Pyrometer Circuit
To make a furnace temperature meter, the sensing element is required to be particularly robust so that it is able to withstand the extreme high temperatures generally developed in furnaces and ovens. What is a Furnace The circuit of a pyrometer explained here is based on a thermocouple principle which can be used to read […]
FM Wireless Microphone Circuit – Construction Details
A wireless microphone is a portable electronic microphone which allows the user to transmit its voice to an amplifier without any wire connection, hence the name wireless microphone. Making a wireless mic at home can be real fun, here I have explained one such simple project which can be used for recording and paying back […]
How to Make a Bicycle Horn Circuit with Ringtone
A bicycle horn is normally used in bicycles for generating an amplified alarm sound with a press of a button for alerting anybody getting on the path of the running bicycle. In this post I have explained the complete construction of an electronic bicycle horn circuit which will resemble a phone musical ringtone sound. Introduction […]
Sequential LED Array Light Circuit
In this article I have explained how to make a sequential LED array light circuit with an sequentially illuminating LED forming a bar graph kind of LED formation. Introduction In this article I have explained a simple method of making an incremental LED light using the IC 4017, which is rather equipped with specifications not […]
