Flashlight Circuit with Long Backup and High Efficiency
There are two main advantages of this highly efficient flashlight circuit with long backup. Firstly, it uses only a single 1.5V AAA cell and illuminates a 3.3V LED. Secondly, the 1.5V cell is consumed by the LED until there’s virtually no charge left in it. Due to these features, this flashlight is able to last […]
Simple 48V Inverter Circuit
In this post I have explained a simple 48V inverter circuit which may be rated at as high as 2 KVA. The entire design is configured around a single IC 4047 and a few power transistors. Technical Specifications I am a big fan of u….i am a wisp. i need an inverter design with 48volt […]
Make Your Own Rapid Sea Water Desalination Plant at Home
A simple, low cost set up I have explained in this article will give you a clear idea regarding how to desalinate sea water at a fast rate and in large quantities. The conventional method of solar sea water desalination process is quite sluggish and cumbersome. A simple, low cost but effective idea presented here […]
Regulated, High Current Power Supply Circuit
The circuit I have explained below can be used for applications that require stringent voltage regulations and ripple rejection criteria. The transistor pair are configured such that all residual ripple factor are perfectly rectified. Circuit Operation The circuit below shows a simple way of acquiring a perfectly regulated and stabilized high current DC voltage output using ordinary transistors. The circuit […]
