I believe that for the unbelievers in shopping on the internet safely billet option comes in handy. A few days ago I made a purchase, de um Kit com “30 pcs” (when they say ...Continue reading..
Not only commercial electronic devices that can be printed circuit boards, the printed circuit boards can be built by anyone at home, provided you have some basic tools and a few products, I think the most common is iron perchlorate, in which we will talk later. The printed circuit board also called PCI or PCB ...Continue reading..
The electrical brain stimulation made headlines a few weeks in a TV show, and after it received hundreds of emails asking about the subject. For my part I believe that electrical impulses must do something in the brain, this has been proven for decades and widely used in mental hospitals and psychiatric clinics, this treatment was called or popularly called electroconvulsive ...Continue reading..
I'm starting to write an e-book in which I intend to teach basic electronics who is starting. I'll try to use simple language to try to achieve those users without affinity with the area. It will not be like any electronics course Senai, will not delve, but to give a basic understanding, enabling any user to understand a little electro-electronic, ...Continue reading..
There are electronic circuits that eventually get famous and receive up names, this is the famous case of this FM transmitter is called Veronica. The circuit is simple, it is a clear FM transmitter that does not use integrated circuits and is known for its extreme frequency stability and an FM signal clean and. The FM transmitter Veronica is originally designed to have ...Continue reading..
Here is another electronic circuit of a driver for Led, this project is identical to the previously published, a current regulator for LED High Brightness 1 Watt tipo estrela ( Led Driver). He is part of a series of publications on Led Driver. This driver uses the famous LM317 voltage regulator, which in this case is configured ...Continue reading..
Australian researchers have managed to create a transistor that has the size of an atom. This is the smallest transistor ever created in the world. Considering that transistor single-atom, has only 0,1 nanometers in size. If you ever thought a SMD transistor difficult to weld to weld so I want to see this “transistor atômico” .. () Possible applications for this ...Continue reading..
Currently almost all connections are made to PC via a USB connector, como mouses, keyboards, printers, digital cameras, Arduino and almost all digital peripherals . E USB stands for Universal Serial Bus, this pattern was designed in mid- 1990 to replace the serial and parallel ports. There are three USB standards, USB 1, USB 2.0 e USB 3.0. How much ...Continue reading..
