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 […]
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 […]
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. […]
[Chris] has been spending a lot of time in the wife’s sewing room lately, and things got pretty serious late last night as he hacked his shiny new Rigol DS1054Z to unlock the 1104Z capabilities lurking within. The rumors are true, and ungoverning the software is as simple as looking up your serial number and knowing the right URL […]

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 […]

[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″ […]

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 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 […]

First, lets start with that, this tutorial wont work if your computer is connected to Windows domain. If you are not sure whether you are connected or not, following the next steps will not change anything fatally. Anyway, if you want to be able to use several parallel sessions of Remote Desktop, you must have […]

We’ve all had that problem. Up on stage, rocking out Jimi Hendrix-style on guitar with your band, but frustrated at having to mess around with foot pedals to control all of the effects. [Richard] solved this problem in a unique way: he put a preamp and a microcontroller in a guitar that can create some very […]

A few months ago Hackaday covered the xNT crowdfunding campaign which aimed at making an NTAG216 based NFC implant for different purposes. I actually backed it, found that standard NFC readers don’t perform well and therefore decided to try using a standard coil as an antenna for better reading performances. Most NFC readers typically only have a […]
