In the world of electronics we have impedance; the combination of all forces which oppose the flow of electric current. Often times we have circuits with different impedances, 50 ohms for RF, or 75 for cable TV. It’s pretty important to use the right coax in these circuits, else you’ll be wondering why your RG-58 [...]

Most of you already know what a diode is, but how much do you really know about the device? The diode is a component which allows current to pass in only one direction. Originally they were made by placing a positively charged anode plate within view of a tungsten cathode in a high vacuum. By [...]

As an RF engineering student, [Camerin] is usually tasked with pointless yet educational endeavors by his advisor and professors. Most of the time (we hope) he sees the task through and ends up pulling something out of his hat, but a few days ago a professor dropped a bombshell on him. After reading this article on [...]

Although award shows aren’t necessarily our thing, [T. D.] sent in something that piqued our interest. His friends recently got back from the Grammy awards where they witnessed thousands of LED bracelets blinking in time to a performance by Coldplay. A little bit of YouTubing pulled up this video that demonstrates the effect (because that video will [...]

[Martin] sent in two videos he found while cruising the tubes. The first video is a simple circuit with a resistor, three switches, and three LEDs. All the components are soldered together right in front of the camera. When a battery is connected, turning the first switch on makes the first LED light up. Turning [...]

[Tim] wrote in, lamenting a problem that many of us can likely echo. Over the years, he has acquired all sorts of small electronic parts and components, along with tools and accessories – all of which are starting to crowd his workspace. He says that most of his stockpile is being stored in a tackle [...]

One of the members of the SomethingAwful forum recently found a black project box on the street (as seen above), with no idea what the thing did. After (hopefully) making sure there were no explosives, [noapparentfunction] posted a picture online to see if someone could figure it out. According to them, this is what the [...]

Quick, go to answers.hackaday.com and sign up for an account. Ages ago, we announced that we would be bringing a community driven question and answer system to Hackaday. We eventually got tired of waiting for the feature to be provided and improvised. Well, the wait is over. You can now post your own questions and [...]

A while back, we announced that we would be bringing new features to Hackaday. One in particular that garnished a lot of interest was our question answer type thingy. Well, in case you hadn’t noticed, that has not happened yet. Without divulging too much into the secret machinery that lies underneath Hackaday, I’ll just say [...]
