After taking mental note of the number of surveillance cameras pointed at him while standing in line at the local Home Depot, [Mac Pierce] was inspired to create A Scanner Darkly. The art installation uses beams of light projected by mock security cameras to create a dot-matrix character display on the opposing wall, which slowly blinks out US […]

A beach is always a relaxing summer vacation destination, a great place to hang out with a drink and a book or take a swim in the ocean. For those who need a more active beach-going activity with an electronics twist, though, metal detecting is always a popular choice too. And, of course, with an

Like many of us, [quincy] feels the distracting pull of non-work programs on what has become a mixed-use computer. So what’s the answer to the puzzle of work-life balance? We’re not sure, but time management and keeping track of tasks will probably get you most of the way there. The only problem is that keeping
ROTARY TIME TRACKER PUTS A NEW SPIN ON PRODUCTIVITY Continue Reading
A popular tool in chiptune software like LSDJ allows the user to draw a waveform and use it as the basis for a wavetable synth. It’s fun and it can produce some great bleeps and bloops. [Kevin] has created a similar tool using an Arduino and a touchscreen. The build is based on the Arduino Uno,

Arduino developers, students and enthusiasts may be interested in the Segger Arduino debugger, “Debuggers are the scalpel that allows a developer to dissect any application code running on embedded hardware. “Arduino has partnered with Segger to help support developers in creating their own embedded systems, implementing compatibility of Segger debugging solutions with Portenta boards. “Ozone is Segger’s full-featured
Segger Arduino debugger helps your development workflow Continue Reading
Small portable soldering irons are all the rage so [electronoobs] decided to build one on his own. While the design isn’t quite as sleek as a commercial unit, considering it holds its own batteries, it looks pretty good. Of course, the question is: does it work? You can see in the video below that it does,

It’s no surprise that many hardware hackers avoid working with AC, and frankly, we can’t blame them. The potential consequences of making a mistake when working with mains voltages are far greater than anything that can happen when you’re fiddling with a 3.3 V circuit. But if you do ever find yourself leaning towards the
CUSTOM ISOLATED VARIAC IS TRULY ONE OF A KIND Continue Reading
With the world opening up again, [Niklas Roy] and [Kati Hyyppä] have been busy making a public and collaborative project. Meet the Vektor Kollektor, a portable drawing machine experience, complete with a chip-tune soundtrack. It’s great to see public art meet the maker community with zero pretension and a whole lot of fun! The build started

Raise you’re hand if you’ve ever soldered directly to a battery even though you know better. We’ve all been there. Sometimes we get away with it when we have a small pack and don’t care about longevity. But when [Robert Dunn] needed to build a battery pack out of about 120 Lithium Ion cells, he
GORGEOUS BATTERY WELDER HITS THE SPOT Continue Reading
The team responsible for officially pushing forward the Arduino ecosystem has this week introduced a new industrial grade development board in the form of the Arduino Portenta H7 Lite. Powered by a dual-core STM32H747 including a Cortex M7 running at 480 MHz and a Cortex M4 running at 240 MHz. The two cores communicate via a
