  • How to Display Video On A Screen With Only One Wire

    In today´s article we bring you a great tutorial about NTSC. For those who don´t know this, NTSC is another video standard, like VGA, very popular in the Americas and Eastern Asia. However, unlike VGA, NTSC only uses 1 signal wire! The principal behind that is quite complex. Thus, the example developed on the article…

  • How To Control What You See On A Screen in Two Hours and For Less Than $25!

    Imagine how cool it would be to control what appears on your screen and at a bargain price, just using your FPGA (yes! Your Papilio!) and some other easy-to-get components. All you need is read today´s article (and buy the tiny things of course). This how-to post is one of those which are written thinking…

  • Do you feel like a hanging-down bat? Let´s build something to find out!

    Today´s article will teach you how to create your own FPGA-based tilt sensing device. It is one of those really thorough tutorials where almost nothing is left to your imagination but the infinite applications you may develop. Cool right? This project is based around the DEo-Nano board and its built-in tilt sensor. I am pretty…

  • Start Playing With Your Papilio Pro Logic Analyzer!

    https://youtu.be/D7FWUJoVaIc If right now you are kind of what is this guy talking about? Then you should check this and learn one of the almost infinite applications of a Papilio Pro. Today, we bring an article that explains one use for your brand new Papilio Pro Logic Analyzer. This is to capture the communication via…

  • You´ve got the Power in your hand or, better said, in the Wheel of your mouse!

      https://youtu.be/cWH4kVPpL3Y Today´s article will teach you how to build a system to control big power. You can use it to manage a simple light bulb or a 0.5 kW motor without having to change a single line of code. The key of this design is the implementation of a widely-used jellybean wheel from a…

  • Do you have an Arduino UNO? Then you have a logic analyzer!

    This tutorial shows, step-by-step, how to turn your Arduino UNO into a 6 channel SUMP. This logic analyzer is able to sample signals with a speed varying between 4 MHz and 10 kHz. Best results are obtained below 1 MHz. Above this mark, there is too much of a lag between the trigger detection and…

  • Program your FPGAs and CPLDs at zero cost with the BBB

    Today, we present a thorough tutorial on how to take advantage of the BeagleBone Black to implement programmable logic. This is a very easy procedure. It is browser-based, and you just need to drag and drop your programming files into the beagle, wait a few seconds…and done! That simple! The recommendation is to start with…
