Detect a magnetic field and its changes is the operating principle of thousands of electronic devices, as the metal detector and other. From a simple circuit can improve it according to our needs, often this is the best way out than to develop an electronic circuit zero. In this article we describe an electronic circuit ...Continue reading..

Brazil is a champion when it comes to lightning, Here is where there is the highest incidence of lightning in the world, this phenomenon is very dangerous and cause millions of dollars in annual property damage and dozens of fatal victims. We did two very interesting articles with electronic circuits Lightning Detector: Ray Detector 1 and ray detector 2. ...Continue reading..
One of my hobbies is the detectorismo, I even have a blog about metal detectors (somewhat out of date due to time). In this area we see many strange things with wands who find gold and diamonds, longa detectors distância, detectors gold ionic, among other things beyond explanation electronics, physical and even psychiatry. I think for all ...Continue reading..
Here we show a simple detector of electromagnetic radiation to, and which can detect high frequency signals such as cellular phone. I've always been an enthusiast of RF and know their misdeeds health, despite much controversy in electronic media, is impossible to deny that electromagnetic radiation has no effect on the ...Continue reading..
Since joining the hall of essential household appliances for a house, o forno de micro-ondas não teve quase nenhuma evolução, is basically the same since its invention, by volta of 1937. No começo houve muita polêmica sobre esse método de cozimento de alimentos, but now we know that health risks are zero. The oven ...Continue reading..

Often we need to see which is ideal for the placement of an antenna point, a transmitter or any high frequency device, where its signal can reach and where the ele. For this we can use a detector circuit, also called sniffer, that is tuned to the operating frequency of the desired system. This detector described ...Continue reading..
I was looking for something interesting about one of the projects of Tesla when I came across a very cool circuit, which referred to electromagnetic levitation. Levitation always aroused very human curiosity, since it was associated with magic and things beyond. Magicians levitate objects or their Partners, not counting the flying saucers that levitating cows abduziam them. Out ...Continue reading..
I love the detectorismo, this is actually one of my Hobby's, if you want to know more you saw the blog Metal Detector, there is lots of interesting information. But let the circuit, The principle of operation of this detector circuit home metal consists of a mixture of two equal frequency causing interference. When one of the oscillators become unstable, the interference frequency is ...Continue reading..
This is a very interesting circuit of a fully transistorized metal detector, it is simple to build a detector, uses only 4 transistors, being 1 in step transmission (transmitting coil) and 3 receiving transistors in step. The scope of this metal detector is relatively good, its sensitivity is adjusted by potentiometer and 1Mohms ...Continue reading..
