  • Build your own Mandelbrot Fractal Generator with FPGA

    Greetings FPGA lovers! Today’s post takes you into yet another interdisciplinary project that links pure mathematics, FPGA and VHDL to build something beautiful! The Mandelbrot set is a series of complex numbers that tend to infinity when operated upon by a special operator. These numbers when grouped together create a beautiful image sequence which might…

  • 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…

  • Test Your Dec to Bin Conversion Skills with Your FPGA

    https://youtu.be/5AtFMXq4ihQ Hello FPGA enthusiasts! Today’s project takes you back to school where you learned the binary system. The author has designed a decimal to binary conversion game using FPGA. It is time to see if you did pay attention in class! The game uses a random number generator which generates any number between 0 and…

  • 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…
