  • Create A Particle Dynamics Simulator With Your FPGA

    Today´s article presents a very detailed project of a Cornell student who wanted to play with Pyro Sand Game. He did not want his laptop to overheat due to high power consumption, the fan to go crazy or the screen to freeze up once a lot of particles were on screen. To solve this he…

  • How To Implement The Old Oberon System On A Modern FPGA

    In today´s article we bring you an experiment carried out by Niklaus Wirth, a master of the Computer Science World. But this article goes beyond itself. It is much more than that because it is the introduction chapter for a thorough guide on how to implement the Oberon system, developed in the late 80´s on…

  • Commodore PET is Back!

    You read it right. Commodore PET has come back to stay…if you want. Thanks to this article you will be able to bring back old memories and, of course, have some fun. Basically all you need is a FPGA, implemented in Verilog. Well, and you will also need some other tweaks and stuff in order…

  • 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…

  • Here is How The Dark Side Got Started With Their Robot Army!

    Nowadays, you may be fed up of Star Wars jokes, baits and so on. I am sorry, I could not resist the temptation. Anyway, this time, at least, was not a joke nor a lie. Today´s article brings the real truth to you. If you want to build your own robot, as simple as you…

  • Learning Verilog for FPGAs: Flip Flops

      Creating an adder on Verilog and putting it into an FPGA board can be done in various ways: With or without clocks.  A very detailed and thorough tutorial explains how to use clocked elements to verify whether the adder has ever generated a carry as well as a few counters. Using clocks avoids getting glitches and…

  • ZX Spectrum ULA Chip Implementation On OBLS

    Above: OpenBench Logic Sniffer running the ZX Spectrum ULA chip clone. As a follow-up to Friday’s article on the ZX Spectrum clone running on the Pipistrello, I thought it would be good to share a little more with you on the implementation of the Sinclair ULA chip. The chip was originally included in the ZX…

  • Nine Digit Problem Solved In 2.2 ms The FPGA Way

    Here’s the problem: The folks over at Programmable Gatorade wanted to take this classic math problem and put their Altera Cyclone IV FPGA board to use in solving it. The design uses the board’s 50MHz clock and finds the solution in approximately 2.2ms. There are three main components to the design: a module to calculate…
