One of my friends who is an inventor, a mad scientist and an intense electronic enthusiast Mr. Steven Chiverton is always upto discovering and making intriguing electronic circuits and gadgets. His outstanding efforts in the field of electronic is worth sharing and learning. After many months of disappearance, just a few days ago I received […]
Newly Updated Circuit Projects:
Use your PC like an Oscilloscope
As an electronics enthusiast or a hobbyist, you probably yearn for an oscilloscope to check out those elusive waveforms in your amplifier or radio. However, the cost deters you. A reasonably good oscilloscope will set you back by several hundred dollars, unless you buy a pre-owned piece or get one at the flea market. However, […]
Basics of Strain Gauge Measurements
The strain gauge is one of the most useful tools for precisely measuring expansion or contraction of a material as forces are applied. Strain gauges are also useful for measuring applied forces indirectly if they are aligned approximately linearly with the deformation of the material. What are Strain Gauges Strain gauges are sensors whose electrical […]
Cheapest SMPS Circuit Using MJE13005
The explained circuit in this article is probably the simplest and the cheapest, since it employs minimum number of components and the making of the circuit is very straightforward. Circuit Operation Generally SMPS topology involves some fixed standard stages and criteria. Thgey may be listed in the following manner: The first stage which is the […]
Low Battery and Overload Protection Circuit for Inverters
A very simple low battery cut-off and overload protection circuit has been explained here. The figure shows a very simple circuit set up which performs the function of an overload sensor and also as an under voltage detector. In both the cases the circuit trips the relay for protecting the output under the above conditions. […]
Make This 1KVA (1000 watts) Pure Sine Wave Inverter Circuit
A relatively simple 1000 watt pure sine wave inverter circuit is explained here using a signal amplifier and a power transformer. As can be seen in the first diagram below, the configuration is a simple mosfet based designed for amplifying current at +/-60 volts such that the connected transformer corresponds to generate the required 1kva […]
