How to Illuminate 1 Watt LEDs with Cell Phone Charger
Nowadays probably all of us have a spare cell phone charger lying idle in our cupboards or table drawers……so wouldn’t it be a great idea if we could employ it like a super bright 1 watt LED driver and illuminate our room with white cool moon light. Circuit Concept As we all know that a 1 watt […]
75 Watt Power Amplifier Circuit
Our power amplifier only uses a handful of widely available and inexpensive components. Despite this, it can deliver an effective power output of 50 W into an 8 ohm load or 75 W into a 4 ohm load. If distortion is below 0.3% at these maximum power levels, it drops to less than 0.01% from […]
2 watt Amplifier Circuit
A very simple 2 watt audio amplifier circuit has been presented here which can be constructed by all new electronic hobbyists for amplifying small signal frequencies and for other similar experiments. Circuit Operation
DIY 100 Watt MOSFET Amplifier Circuit with PCB
MOSFET based amplifiers as we all know are outstanding with their sound qualities and they can easily beat the performance of other counterparts based on power transistors or linear ICs. Why use MOSFETs in Amplifiers Amplifiers based on mosfets are not always easy to design or make. Moreover after assembling a prototype, testing to perfection […]
Hi-Fi 100 Watt Amplifier Circuit Using 2N3055 Transistors – Mini Crescendo
Video Demonstration of the Crescendo Amplifier The mini crescendo 100 watt transistorized amplifier circuit explained here was built and tested by me and am extremely pleased by its performance and also its ruggedness as far as maintenance and handling is concerned. Amplifier Class Basically, the entire configuration is a symmetrical class A amplifier incorporating an […]
