Hello friends.
We like to collecting the electronic circuits with PCB layout as ideal of building the Easy electronic projects, under different scenarios.
The projects are mostly old but still works great. Suitable for use or to study.
Now, We have a lot of articles(over 600 circuits). So, difficult for find the circuit as you need. It is a pity if you close this site without the great experience.
Recent New PostsThe automatic Gian control circuit also AGC with audio signal is simplest for compress to signal in the Radio receiver. It is ideal for short wave radio receiver used in areas with weak signals. You should adjust the master volume control dress until the desired signal intensity. While tuning the receiver to the station light, […]
How to use TL497 as the switched-mode power supply projects that output current of 500mA, and there are 3 model: step down,step-up and inverting voltage converters. Now, a switching power supply is high popular. Which we are use to suggest a lot of projects. Those who want the switched mode power supplies that has small […]
This circuit is Low dropout 5V regulator that use LM317 as main. The voltage input is 5.1V DC is converted into 5V output,while the maximum output current is 2A by TIP41 increase current. How it works From this circuit: Low dropout voltage regulators circuits that can converted voltage input from 6V to 5V output,they uses […]
In the event of we need to build a variable DC power supply that output of 1A and can adjust up to about 30V. Most people will use LM317 because high-efficiency, easy to apply and cheaper Description It have an adjustable 3-terminal positive voltage regulator designed to supply more than 1.5 A of load current […]
This is a simple low pass frequency filter circuit on nonlinear passive. We use passive components without transistors and any ICs. So is easy circuit. and It is small size and easy to made for do not used the external power supply, but refuse a lot of noise ripples and need to a input voltage […]
