MEGA COLLECTION OF ELECTRONICS DIY PROJECTS
Every week, we publish 2 to 3 projects, sometimes even more! They range from simple circuits for beginners, to advanced projects that you can use to develop complete innovative products! Most projects have been developed by enthusiasts like you. Some by experts. And, some by our team. Many are tested at EFY Labs, and some are not–but they typically have a proof-of-concept video.
Simple 5W Mono Audio Amplifier
This mono AF amplifier uses a single 5-pin LA4425A IC to deliver 5-watt output through a 4-ohm, 5-watt loudspeaker. The datasheet of LA4425A recommends...

ESP8266 IoT Energy Monitor and Over Current Cut-off
Sockets, boards and wires generally receive a limited supply of electric current. Any 'current overdraw' from them via thin wiring can result in a...
Smart Glass That Can Read Books
We have seen many smart glasses to detect the distance between objects or help visually challenged persons to recognise people’s faces. Here we extend...
Control Any TV Using Alexa
One of the impressive characteristics of a smart home is that all electronic appliances can autonomously operate, making them smart. This means that television...
Single-Channel Audio Amplifier
Here is a simple single-channel audio amplifier that can be made using IC LM380N. As per the datasheet, LM380N delivers an output of 2.5...
Milliamp Meter For 1mA To 100mA
Low-current measurements are generally not reliable due to resolution of the measurement devices, which are mainly meant for measuring a current of a few...
