Heads or Tails is one of the most common and simple games that exist, just take a coin and ready. But to make a game face and electronic crown the thing catches, becomes somewhat complex, but nothing to be done printed. This circuit presented here is the simplest and most efficient heads and tails, it uses only two circuits ...Continue reading..
Tesla was truly a man ahead of his time, although seldom reported in literature in Brazil, he is considered a genius in the US (Just to remind, Tesla was not American). We have seen in a previous article the operating principle of the tesla coil , Now we will show some electronic circuits Tesla coils in solid state, a ...Continue reading..
Ends of the circuit simulator and designer of printed circuit boards MultiSIM Blue which is a free version of the popular simulator being launched MultiSIM. This software is a partnership of Mouser Electronics, and National Instruments, that to be able to provide a free version. MultiSIM Blue is a light version, ideal for those who do not care about the limitations that do not exist ...Continue reading..
It is very common to have problems identifying the operating voltage of a zener diode, oftentimes, we find the need to use a Zener diode and could not read its value, the characteristics or the type that are written about him. This occurs due to wear or lack of code in the body. If we do not have ...Continue reading..
Currently applications for mobile electronics are increasingly becoming popular, an example of a great app for the electronics area is ElectroCalc. This app is a great tool and electrical calculations for electronic design. Its use is very simple and intuitive, That means that even beginners will be able to use electronics without any problems and ...Continue reading..
The major obstacle for many beginners in electronics is making printed circuit boards, Many users complain about the difficulty of their boards, is due to price, the acquisition of material for fabrication in your city or even the lack of knowledge and technical process. I hate doing the same printed circuit boards, prefer to join 5 or ...Continue reading..
This is a circuit for a battery charger super simple, it is designed to charge batteries NICAR,( NiCd, Ni-Cad , Nickel Cadmium) . Despite being a super simple circuit, use fewer components, it is capable of providing a constant current for charging the battery. Nowadays this type of battery is not used much, ...Continue reading..
This is a circuit of a flasher up 200 Watts of power, but may be increased according to the needs of the user. The frequency and speed of the flash lamp can be adjusted between 1 Hz a 5 Hz, ie between 1 a 5 flashes per second. Ele utiliza or circuit LM555 integrado, an optical coupler ...Continue reading..
An RF probe is a test probe that allows a multimeter or any other measuring instrument measures the oscillation frequency radio (RF), an electronic circuit which can be a transmitter or receiver. No special equipment, like this tip, is very difficult to measure the RF, difficulty arises when one of the RF energy to be measured ...Continue reading..
This is a really cool tip that came from Russia, I found it by chance, and I am sharing with everyone. I myself have spent trouble for soldering or desoldering components in tight spaces and dark. Often takes longer than we thought and the job is done poorly due to these conditions. Good lighting is necessary for technical or lover ...Continue reading..
