  • 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…

  • How to Make a Cleaner Planet with Your FPGA

    Greetings FPGA fans! Today’s post takes power generation and conservation to another level! We all know that Solar Panels are an excellent source of non-conventional power. But if the panel is not facing the sun the power generation is never optimum. The sun changes its position continuously and a static solar panel can only generate…

  • Critical Tips to Build Your Own C88 Homebrew Computer with FPGA

    Greetings FPGA lovers! Today’s post is about building your own mini computer using FPGA. The project has been inspired by the first SSEM, popularly called the Manchester baby. The project resembles its inspiration in certain aspects, but being a homemade CPU with minimal components and coding, the specs are not as formidable as the SSEM.…

  • [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…

  • 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…
