Like many of us, [Josef Adamčík] finds himself fascinated with so-called “freeform” electronic designs, where the three dimensional circuit makes up sections of the device’s structure. When well executed, such designs really blur the line between being a practical device and an artistic piece. In fact his latest design, an ESP8266 MQTT client, would seem […]
CDs were a great advancement in audio quality when they were first put on the market. There’s no vinyl-style degradation of the medium if it’s played over and over, and there’s no risk of turning them into a giant pile of ribbon while rewinding like a cassette tape. The one downside was that if you […]
Robots of the entertainment industry are given life by character animation, where the goal is to emotionally connect with the audience to tell a story. In comparison, real-world robot movement design focus more on managing physical limitations like sensor accuracy and power management. Tools for robot control are thus more likely to resemble engineering control […]
In the practical world we live in, PCBs are often rectangles (or rectangles with rectangles, it’s just rectangles all the way down). When a designer goes to schematic capture things are put down on nice neat grid intersections; and if there isn’t a particular demand during layout the components probably go on a grid too. […]
Light painting is the process of moving a light while taking a long-exposure photograph, which creates a sort of drawing from the path of the light source. It’s been done in one way or another since at least the early-to-mid 1900s, but modern hardware and methods have allowed for all kinds of new spins on […]
Complex 3D-printed designs often require the use of an automatically generated support structure around them for stability. While this enables some truly incredible results, it adds considerable time and cost to the printing process. Plus there’s the painstaking process of removing all the support material without damaging the object itself. If you’ve got a suitably […]
It’s badgelife season, and if you need an idea for a killer piece of wearable electronics, look no further than this PCB Tesla coil. Yes, it’s killer, doubly so if you’re wearing a pacemaker. This project was inspired by an earlier Tesla coil on a PCB project that used 160 turns of 6 mil traces […]
One of the most artistic applications of electrical engineering in recent memory is the burgeoning badgelife movement. This is an odd collective of people who are dedicating their time to rendering their own accomplishments in printed circuit boards. Of the entire badgelife collective, one of the most visible efforts are in Shitty Add-Ons, with a […]
We see all manner of electronics enclosures pass through these hallowed pages. Lasercut wooden builds with fancy kerf bending, expertly prepared acrylic boxes, and even the occasional device cast in concrete. [Mike Kohn] decided that all of these were too permanent, however, and chose a different material – ice. [Mike] shares the ups and downs […]
A word of warning: Google for the definition of the word “pummer” at your own risk. Rest assured that this beautiful solar-powered circuit sculpture fits the only definition of pummer that we care to deal with. For the unfamiliar, a pummer is a device from the BEAM style of robotics, a sort of cyborg plant […]
