  • 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…

  • 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…

  • Process VGA without Frame Buffers using FPGA

    Hello explorers of the FPGA Kingdom! Today’s project digs into the scope of FPGA as a tool that can replace conventional techniques further. VGA or video processing through conventional means requires a frame buffer which stores a block of data regarding pixel information in the system RAM for video display which is transferred to the…

  • 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…
