Variable Power Supply using LM317 1.5 – 15v dc
Introduction to variable voltage regulator :– A variable power supply unit is a very useful tool that provides the constant derived voltage output with constant current rated by the unit. A variable power output tool is a necessity for electrical and electronics hobbyists and professional work.These are circuits built using active and passive components(diodes,transistor,capacitors,resistors,ICs,etc. HOW […]
Easy Tesla Coil
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 […]
