  • 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…

  • Build an Autonomous FPGA Search and Rescue Vehicle

    Hello again FPGA lovers! Today’s project is a challenging one where you build an autonomous search and rescue vehicle with FPGA! The projects involves the use of 2 vehicles, where one searches for the target with the aid of an FPGA, while the other uses minimal sensory aids to follow the search beacon and rescue. The…

  • All You Need Is 2 Wires And 50 Bucks To Get Video Out Of Your Arduino With Mesa-Video

    In this post we want to introduce you a great article that describe the latest projects from Black Mesa Labs. These guys wanted to create a new approach to add video support to your projects with Arduino and other low cost microcontrollers. So the idea of Mesa-Video was born. Mesa-Video is a fully open-source device…

  • How to Display Video On A Screen With Only One Wire

    In today´s article we bring you a great tutorial about NTSC. For those who don´t know this, NTSC is another video standard, like VGA, very popular in the Americas and Eastern Asia. However, unlike VGA, NTSC only uses 1 signal wire! The principal behind that is quite complex. Thus, the example developed on the article…

  • Feeling like Barenboim? Check it with your FPGA!

    Today´s article shows how a group of students from Cornell University, created a hardware-software set of tools to develop and composed your own music, the Audio Composer and Conducting Suite (A.C.C.S). This virtual conducting environment platform is capable of inputting the compositions from a video camera and a keyboard or a conductor waving his/her hands…

  • Spit out VGA with non-programmable logic chips

    Bitbanging a VGA can be a tough task due to the timing requirements. Nevertheless Sven gave it a go and not only he bitbanged a VGA on an arduino, but he managed to configured an array of 7400 logic chips to output a VGA signal. Consisting of two parts, his project first consisted in outputting a…

  • Kickstarter Lessons Learned Presentation at the DaVinci Institute in Denver, Colorado

    I was asked to speak at a local Inventors Institute about the lessons learned from my recent Kickstarter’s. Here is a youtube video of that presentation.  

  • Linux on the Papilio Pro?

    Linux on the Papilio Pro? Alvaro Lopes has Linux running on the ZPUino simulator and expects it to run on PPro soon! Watch the video of Linux running on the ZPUino simulator, everything including the SD card is simulated and helped him speed up the porting process. Now that everything is working in the simulator…
