In this post I have explained 8 easy methods of building touch sensor switch circuits at home, which can be used for switching 220 V appliances ON/OFF with mere finger touch operat ions. The first one is a simple touch sensor switch using a single IC 4017, the second one employs a Schmidt trigger IC, […]

Making a Time Machine – Concept Explored
Wondering how to travel in time? Learn it with great Sir Stephen Hawking, according to whom time warp may be an option but seems pretty impractical, the reason being the feed back loop which will just oppose the feasibility of making a time machine and the concept using this theory. Are you intrigued by the […]
Modified Sine Wave Inverter Circuits using IC 555 and 4017
When an inverter with square wave AC output is modified to generate a crude sinewave AC output, it is called a modified sine wave inverter. The following article presents interesting modified sine wave inverter designs with exhaustive descriptions regarding its construction procedure, circuit diagram, waveform output and detailed parts lists. The designs are intended for […]
2 Simple RF Detector Circuits Explored
In this article I have explained a couple of very easy to build RF detector circuits, which can be used to sense or detect or sorts of Rf electrical noise that may be floating in the surrounding atmosphere. What is RF RF stands for radio frequency, which is a kind of electrical interference transmitted in […]
4 Useful Logic Probe Circuits Explored
These simple yet versatile 4 LED logic probe circuits can be used to test digital circuit boards such as CMOS, TTL or similar for troubleshooting the logic functions of the ICs and the associated stage. What is a Logic Probe A logic probe circuit is a handheld electronic tool which can be used to test […]
4 Solid-State Car Alternator Regulator Circuits Explored
The 4 simple car voltage current regulator circuits I have explained below is created as a immediate alternative to any standard regulator and, although developed principally for a dynamo it will function equally effectively with an alternator. If the functioning of a traditional car alternator voltage regulator is analyzed, we find it amazing that these […]
