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 […]
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
This is the night lighting system with LED display, and from battery power. Because the house is not convenient plug So the charging system with a solar cell. Moderately convenient to use. At night, the LED lights up and LED daytime off and electricity from solar cell charged a 12-volts battery. The guidelines circuit design […]
