[powering led with 220 v AC] Have you wondered how Bulbs/lights work directly on mains 220v AC input without a stepdown transformer to lower voltage? The circuit discussed in this article shows and explains how to power LEDs from 220v ac source without using a stepdown transformer. The same concept is used in our modern […]
Hello everyone, our project in this tutorial is a solar rechargeable LED lamp with an inbuilt power bank for phone charging. It is a multipurpose homemade camping device. As the project’s name shows its a very useful emergency purpose or camping device as it can provide you full bright light at night time whenever you are off-grid as […]
Tesla coil is a radio frequency oscillator that drives an air-core double-tuned resonant transformer to produce high voltages at low currents. so let’s get started with our mini tesla coil. Materials 1. 8 CM PVC PIPE 2. 15-20 Metres of COPPER Insulated Wire[motor winding wire], thickness around 0.2 mm 3. 15cm copper insulated wire which […]
