When I builds the circuit Pre tone control by IC LF353 the finished , but can not be usable. Because of it wants a power supply +15V GND -15V at 500mA current. I pairs then builds the group Dual DC power Supply +15V,GND,-15V. By use pillar equipment be IC 7815 , for +15V and […]
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 Posts
ECG is very useful in the medical community. Such as experimental research and development of bio-medical imaging. But this should not be taken with patients because we do not want that. The real purpose is that it is used to preview a heart rate only. In general measuring the rate of heartbeat will get a […]
If you want to build a 10 LED Chaser circuit we suggest this circuit first. It uses popular IC is a simple and affordable IC-4017_decade counter and IC-555. As Figure 1 is LED chaser circuit whicn The CD4017 act as LED driver in 10 output, by LED will glow only one in a rapid sequence. […]
Logic probe is useful tool to measure, in a check digital circuits. As a meter, which is used to measure power in electrical circuits. Logic probe was used for detection logic “1″ and “0″ or pulse in a digital circuit. It has a handle. At the head of a pin, for measuring different parts of […]
If you get the job From teaching science to electronics projects. Elementary education level. This project is right. Is the LED roulette circuits. They uses the principles of digital ICs.Create an integrated LED flashing to the rhythm. And then stopped at one of the LED. Enjoy creating game. And knowledge From digital ICs. Principles of […]
CD4017 CMOS-Decade counter/divider When we build the 10 LEDs running light for hobby. Often use CD4017 CMOS-IC. This really neat chip contains a counter and a decoder circuit, that can show a single output pin for each count from 0 to 9. And also use to build all kinds of timer, LED sequencers and controllers […]
Now A laptop computer has a LCD screen is glass panels. Which have high colorfully and contrast.The disadvantage is reflected into our eyes. So annoying. New Asus laptop AC-400 of me same them. I solved the problem by installing a screen protector. As Figure 1 Features: .Anti glare .Anti fingerprint .Anti UV .Anti Scratching .Easy […]
