Arduino SPWM Generator Circuit – Code Details and Diagram
In this post I have explained how to generate sine wave pulse-width-modulation or SPWM through Arduino, which can be used for making a pure sine wave inverter circuit or similar gadgets. The Arduino code is developed by me, and it is my first Arduino code, …and it looks pretty good 🙂 What is SPWM I […]
8X Overunity from Joule Thief – Proven Design
In this post I have explained about a unique 8x overunity circuit quite resembling a joule thief design which was created by one of the noted researcher Professor Steven E. Jones while experimenting with a simple overunity concept. 8x more Output from a Simple Joule Thief Circuit While developing this overunity circuit he was amazed […]
5 Simple Audio Mixer Circuits Explained
The explained 5 circuits below are universal simple audio mixer circuits, that may be customized and upgraded to 5 channel or even 10 channel mixers, as desired by the user. Contributed by: Anil Rao. Stereo Audio Mixer The operation stereo audio mixer circuit shown below is straightforward: If a mic is “being used,” its output […]
Balanced Microphone Preamplifier Circuit
In this post I have explained about a simple Hi-Fi balanced microphone preamplifier circuit and also evaluate the calculations, specifications of the design through formulas. What is a Balanced Preamplifier A “balanced” amplifier or differential amplifier possesses not one but two distinct inputs and only the difference amongst these inputs is actually amplified. To elucidate […]
Simple Colpitts Oscillator Circuits Explained
In this post I have explained how LC oscillator circuits functions and we will be constructing one of the popular LC based oscillator – Colpitts oscillator. What are Oscillators Electronic oscillators are used in most of our daily used electronic gadgets ranging from digital clock to high end core i7 processor. Oscillators are heart of […]
