  • How To Use Your FPGA To Display Things On A PSP Screen!

    Welcome back to the track of using your FPGA to display things. Today´s tutorial will teach you how to use the LCD screen of a PSP to display colour graphics from an FPGA. The main goal is to show three colour stripes on the screen but the author goes beyond that and adds a quick…

  • Use Your FPGA To Build A Password Cracker!

      Here we have a project developed by a German guy who wanted to get a 100 EUR device that could do 10 million key guesses per second. The main point of this design is to use multiple crypt cores in order to reduce the time needed to crack a UNIX Crypt. A modified DES…

  • Build Your Own Vacuum Robot With Your FPGA!

    This is the first part of the series for building up your own robot, that is fully capable of swallowing up the dust of your room. The first thing you need to build is a fully functional robot that moves independently around your room and that can stop at every obstacle. Well, you have it.…

  • Use You FPGA To Bring The BBC Back To Life!

    BBC is the short name for the Acorn BBC Micro, which was very popular in the mid-to-late 80s. There were several versions of this computer but the one that has been revived in this project is the BBC B. The core of this device was the famous 6502 processor.  This article thoroughly defines each part…

  • How To Add A LCD To Your FPGA And Control What It Displays!

    This great tutorial brings you all the information you need to add a screen to your FPGA.  You will learn about how to choose the appropriate parts for this project, the schematics and as it couldn´t be otherwise, you will also get to know the theory. Mainly, this article explains the theory behind the control…

  • How Building a DPLCM To Learn About FPGAs Turned To Be A Possible Business

    First of all, yes, what is a DPLCM? At least I had to look this up. Now, I can tell you that DPLCM stands for Digital Audio Peak Level and Correlation Meter. At this point we have covered the most difficult part. This tutorial is so well explained, the author even tells you why he…

  • 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…
