    Dumpster Dive Results In 3D Print Server Project

    3D Printers are super convenient when you need a part quickly. However, they can be seriously inconvenient if the 3D printer has to be tethered to your computer for the duration of the entire print. [Matt] purchased a Makerfarm i3v printer and has been using it a bunch. The only thing he wasn’t crazy about […]

    Resurrecting Capcom’s Kabuki

    About a dozen old Capcom arcade titles were designed to run on a custom CPU. It was called the Kabuki, and although most of the core was a standard Z80, a significant portion of the die was dedicated to security. The problem back then was arcade board clones, and when the power was removed from […]

    A Camera With Computer Vision

    Computer vision is a tricky thing to stuff into a small package, but last year’s Hackaday Prize had an especially interesting project make it into the 50 top finalists. The OpenMV is a tiny camera module with a powerful microcontroller that will detect faces, take a time-lapse, record movies, and detect specific markers or colors. […]

  • Running a Web Server on the ESP8266

    We’ve written lot about the ESP8266 lately, but people keep finding more awesome uses for this inexpensive module. [Martin] decided that using the ESP8266 with an external microcontroller was overkill, and decided to implement his project entirely on the module with a built-in web server. [Martin] started out with the ESP8266 web server firmware developed […]

  • 120 Node Rasperry Pi Cluster for Website Testing

    [alexandros] works for resin.io, a website which plans to allow users to update firmware on embedded devices with a simple git push command. The first target devices will be Raspberry Pis running node.js applications. How does one perform alpha testing while standing up such a service? Apparently by building a monster tower of 120 Raspberry Pi computers with Adafruit 2.8″ […]

  • Acoustic Impulse Marker Tracks Sounds With a Pencil

    Two students at Cornell University have put together a rather curious sound tracking device called an Acoustic Impulse Marker. [Adam Wrobel] and [Michael Grisanti] study electrical and computer science, and for their final microcontroller class they decided to build this device using the venerable ATmega 1284p. The system uses a three-microphone array to accurately position sharp […]

  • Brushless Motor Controller Shield for Arduino

    Brushless motors are ubiquitous in RC applications and robotics, but are usually driven with low-cost motor controllers that have to be controlled with RC-style PWM signals and don’t allow for much customization. While there are a couple of open-source brushless drivers already available, [neuromancer2701] created his own brushless motor controller on an Arduino shield. [neuromancer2701]‘s […]
