  • Protect Your Home With a FPGA-based Alarm System

    Welcome back again FPGA addicts! Today we have a very interesting and useful project for you: Build your own alarm system with your FPGA. This work was carried out by a group of students and it could perfectly serve as a baseline for any alarm system. The project is developed in 6 easy steps. All…

  • 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…

  • Want a Logic Analyzer?? Then just get a Papilio!

    https://youtu.be/pqCo8yAhLhQ Not long ago we published an article about using an Arduino UNO as a logic analyzer. As it couldn´t be otherwise, you can also do the same with a Papilio. And guess what? The Papilio-based logic analyzer is more powerful. No hype, just real numbers. You can achieve 32 channels, at 200 MHz, while…

  • 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…

  • Do you have an Arduino UNO? Then you have a logic analyzer!

    This tutorial shows, step-by-step, how to turn your Arduino UNO into a 6 channel SUMP. This logic analyzer is able to sample signals with a speed varying between 4 MHz and 10 kHz. Best results are obtained below 1 MHz. Above this mark, there is too much of a lag between the trigger detection and…

  • Simple Infrared PWM on Arduino

    Nice code walk through of how to generate a PWM in C code. This is a 3 part series showing how to generate IR commands in software. We are often asked on discussion boards, about conflicts between IRremote or IRLib and other Arduino Libraries. In this post, we present a sketch for ‘Simple Infrared PWM…

  • Spin Brushless DC Motors Slowly

    Here is some good reference material on spinning Brushless DC motors that should be applicable to the Papilio. We would just need to add some sensors to spin the motors faster…   I used specialized triple half bridge IC L6234 (~ 8$). You can make the same spending less money (but more time) with MOSFET…

  • ESP8266: Full Arduino support now! Use it like it’s an Arduino!

    Everyone’s favorite WiFi chip now has Arduino IDE support. This means that you can connect an ESP8266 via a serial port and choose it as a board type in the Arduino IDE now. Make a sketch, click upload and you are in business with a less then $5 IoT device. Pretty nifty! What’s supported by…
