  • 9 Easy Steps to Build a Photosensitive Synth Machine with FPGA

    Hello FPGA lovers! Engineering traditional synth machines using development platforms like Arduino and FPGAs is becoming quite the trend now. Today’s post however takes a twist from the traditional synth machines where sounds are produced by either flicking switches or pressing buttons. The synth machine under discussion is a photosensitive synth machine which uses LDRs…

  • 7-Step Tutorial to Create a Nine Shine LED Timer Game with FPGA

    Hello FPGA lovers! FPGAs are versatile tools that can be used for research, analysis, engineering applications and entertainment. Today’s project falls into the last category! The nine shine LED game is an interactive game that tests your sense of timing. It consists of an array of LEDs that are turned on sequentially, and you need…

  • Visualize Music with a Muscled FPGA

    The Zybo Board is one of the most powerful tools in FPGA and this is because it is FPGA combined with an ARM processor that widens the spectrum of possibilities with FPGA. Today’s post is yet another dive into Zybo’s possibilities and in this project a visualization of audio signals or music will be accomplished.…

  • Build Your Own Globe of Persistence with FPGA

    Hey there FPGA lovers! The human eye is far from being perfect, and this imperfection helps us in coming up with a lot of ideas and products (take the television for example!). Today’s post exploits the Human eye’s persistence of vision to build a globe of persistence using FPGA. These globes can be used to…

  • How to Build an Arcade Obstacle Avoidance Game Using FPGA

    Hello FPGA innovators! Remember the arcade obstacle avoidance game where blocks of pixels fall on you and you steer clear of them moving left or right? Today’s project attempts to re engineer the same game using a VGA and FPGA. Here, a pseudo random code is used to generate obstacles that fall down and buttons…

  • How to Create a Visual Audio Spectrum with a FPGA in 5 Steps

      Hello FPGA lovers! Today’s post is an interesting one which helps us visualize the audio spectrum with the help of your FPGA and an LED strip. Using a VGA cable, the spectrum can be visualised in a computer monitor as well. The microphone on the FPGA used (you may need to adapt this to…

  • [DIY] How to Make a FPGA-based Electric Composer

    Hello FPGA enthusiasts! Today’s project takes sound production using FPGA to another level. The project under focus is building an electric keyboard/composer using FPGA. The keyboard acts as a song tune composer where a network of switches on the FPGA board is connected in precedence such that while a switch is on, the corresponding note…

  • How to Build an Automated Intelligent Room Lighting System with FPGA

    https://youtu.be/k5gNt69FuBU Hello FPGA lovers! The project in focus today is aimed at creating an Intelligent Room Lighting System with FPGA, where you can bid adieu to the use of switches! The system is powered by an FPGA board connected to a set of LEDs that turn on depending on the number of people in the…
