  • 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…

  • Controlling Stepper Motors with Joysticks using FPGA

    Greetings FPGA innovators! Stepper motors can be an integral part of projects that have a dimension of mobility to them. Be it rovers, robots, drones or claw machines, controlling stepper motors with joysticks is an integral part and FPGAs accomplish speed control easily. Today’s post is about using a FPGA and a joystick to control…

  • 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…

  • Save on Your Electricity Bill with Your FPGA

    Greetings FPGA innovators! Ever had the problem of forgetting to switch off the room lights on your way out? Do you have frequent guests who are not as mindful as you when it comes to power saving? In today’s project we see how to build a simple gadget with the FPGA to switch off your…

  • Remotely Control your TV with Your FPGA

    Hello FPGA enthusiasts! The FPGA is truly a tool that can stretch the horizon of possibility and in today’s project we will find out how an FPGA can be used as an universal remote control. Ever had the problem of falling asleep while watching TV? Not anymore! The Universal Timed remote with FPGA is a…

  • Very few know how Powerful this FPGA combination can be – Here is how to Control it

    Greetings inhabitants of the FPGA world! Today’s post is about a project that can be a huge part of a number of other different projects that use FPGA as their core. Be it a claw machine or a drone or a navigator robot, interfacing Joysticks with FPGA will be a fundamental part of many of…

  • The Daredevil Cam is Closer to Those with this Info and a FPGA

    Hello FPGA hobbyists! Ever wondered what it would be like to see sound? The author thveryat very same curiosity for close to 10 years, and kept a constant vigilance for ideas to build something that would help him materialize his dreams. The Daredevil camera, built using a bunch of MEMS microphones and a FPGA actually…
