  • [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 Synthesise Music with YM 2151

    Hello FPGA lovers! Today we are going to share another instalment of our YM 2151 post series. According to the author of the original article (in Spanish), the best way to produce sound using the YM 2151 is to use the 6809 assembler which is a cross targeting assembler seen usually in Motorola and Hitachi…

  • Using the YM 2151 for Noise Generation

    Hi there FPGA lovers! Here we have another release of our series of YM2151 posts. To recreate the YM 2151 in FPGA using VHDL, every aspect of the YM 2151 needs to be mapped on to the recreation platform. However an interesting aspect regarding the YM 2151 is that it uses random values for generation…

  • Create Studio Quality Sound with YM 2151 and FPGA

    Hello FPGA lovers! Today’s post is about making real studio quality music rather than the monotone buzzers from conventional circuits. FPGAs can be used to create monotone sounds such as beeps by using the right combination of DACs and buzzers. However these devices cannot be used to create studio quality sound that not only plays…

  • 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…

  • Build Your Own Digitized Tic Tac Toe with FPGA

    Greetings FPGA enthusiasts! Today’s project is a rather exciting one where we will attempt to build a Digitized Version of the popular Tic Tac Toe game with FPGA. This Tic Tac Toe FPGA implementation is pretty simple so this is a great project for a newbie too. So game on! The Hardware requirements are pretty…

  • Build Your Own Hexapod Robot with FPGA

      Hello FPGA lovers! Today’s project is going to be a challenge on mainly 3 fronts. The Project at hand is to build a Hexapod Robot based on FPGA, and the 3 challenges are to get the Hexapod to work with FPGA, design and simulate it with CAD and to carve and glue the parts…

  • Build Your Own SuperH CPU with FPGA

    Hello FPGA enthusiasts! Today’s post is a rather special one since it throws open doors to a 32 bit CPU that you can quite simply build with a Spartan 6 FPGA board. Hitachi’s SuperH CPU patents have passed the 25 year mark, and this means that the technology can be reproduced at much lower costs…
