Exploded Hardware Wall Art

explodedHardwareWall

The gang at Bolt.io realized that the walls in their office deserved some special attention, and they got it by mounting exploded hardware throughout the space. They sourced the used devices from eBay, then carefully broken them down into their components and mounted each on its own sheet of PETG. The result: exploded views of some of their favorite hardware, including a MacBook Pro, a Roomba, a Dyson Air Multiplier, and more.

Is it a hack? Eh, maybe. This is the first example we’ve seen of a collection of devices on display in this fashion. Regardless, it’s worth a mention considering what happened in the office as a result of the installation. Though the original purpose was simply to decorate the walls, it seems employees have been staring at them regularly, learning more about the designs, the plastics, and the component choices. Think of it as still life—depicting that moment you cracked open a device to inspect its guts—frozen in permanence and on display for both inspiration and convenience.

Built-in Coffee Table Lightbox

diydollarstorelightbox

[Flyingpuppy] sent us this tip about her cleverly-concealed pull-out lightbox drawer. Her resolution for the new year was to make more art, so she filled this coffee table with art supplies and decided she’d draw while relaxing in front of the television. She also wanted a lightbox nearby, which originally involved hacking the entire tabletop with some acrylic, but she eventually opted for a simpler build: and it’s portable, too! The drawer’s lights are battery-powered, so you can pull the entire thing out of the table and drag it onto your lap, if that makes drawing more comfortable.

[Flyingpuppy] sourced seven inexpensive LED units from her local dollar store, which she mounted to the back of the drawer with some screws. The rest of the drawer was lined with white foam board, the bottom section angled to bounce light up onto the acrylic drawing surface. Because she needs to open the case to manually flip on the lights, she secured the acrylic top magnetically, gluing a magnet to the underside of the foam board and affixing a small piece of steel to the acrylic. A simple tug on the steel bit frees the surface, providing access underneath. Stick around for a video below.

Robot Painter Works Like a Photobooth

robot-painter-photo-booth

[Ben], [David], [Drew], [Kayla], and [Peter] built a robotic artist as their senior design project. This mashes up a bunch of different project ideas, but the thing we like the most about it is that it works much like a photo booth that produces a painting. A Raspberry Pi uses a webcam to snap the picture, converts the image to three colors (plus the white background of the canvas) and sets the robot in motion. The team laments that initial testing of the completed project (seen in the clip below) worked out quite well but took hours to produce the painting. What do they expect? It’s art!

This is quite a bit different from the WaterColorBot (whose manufacturing process we just looked in on yesterday). WaterColorBot uses a flat canvas and a gantry system. This offering, which is called PICASSAU, uses an upright canvas with the paintbrush mounted in much the same way as a plotter robot. The biggest difference is that there is the ability to pivot the paint brush in order to pick up more paint, and for cleaning in between color changes.

Backlit PCB Panel as Wall Art

PCB-as-wall-art

For his buddy’s wedding [Saar Drimer] wanted a one-of-a-kind gift, and what’s more unique than a piece of art? He set out to design something that would speak to his geeky game-loving friend. This full-panel PCB is what he came up with. It’s a wall hanging that uses addressable LEDs and a PCB for the enclosure and as a diffuser.

On the right you can see the panel as it was delivered to him. He used routed slots to separate the main body of the enclosure from the four side pieces and the mounting bracket. This design lets him snap off the parts and solder them in place. The only thing you need to add to it is a pair of screws (well, and the components that make it light up).

We’re shocked by how well the PCB works as a diffuser. The substrate is translucent when not covered with silk screen or the copper layers. The outline of the letters uses that, as well as circular areas along the side pieces. The letters themselves are copper fills that have artistic patterns removed from them. This really adds to the visual appeal when the piece is illuminated by 42 WS2812B LEDs. The video below shows the piece in action. It really takes PCB as art to the next level

Priceless Paintings – Scanned and Printed in 3D

painting

When we think of works by Van Gogh and Rembrandt, most of us remember a picture, but we aren’t accustomed to seeing the actual painting. [Tim Zaman], a scientist at Delft University of Technology in the Netherlands, realized that the material presence of the paint conveys meaning as well. He wanted to create a lifelike reproduction in full dimension and color. While a common laser-based technique could have been used for depth mapping, resolution is dependent on the width of the line or dot, and the camera cannot capture color data simultaneously with this method. In his thesis, [Tim] goes into great detail on a hybrid imaging technique involving two cameras and a projector. He and his team eventually used two 40-megapixel Nikon cameras in conjunction with a fringe projector to capture a topographical map with in-plane resolution of  50 μm, and depth resolution of 9.2 μm.

We can’t find a lot of information on the printing process they used, other than references to high-resolution 3D printers by Océ (a Canon company). That said, [Tim] has provided a plethora of images of some of the reproductions, and we have to say they look amazing. The inclusion of depth information takes this a big step further than that gigapixel scanning setup we saw recently.

Check out the BBC interview with Tim, as well as time lapse videos of the scanning and printing process after the break.

‘conus’ mixes media, math and mollusks

conusCA

We love art installations that use technology in ways probably never before considered, and Moscow media artist [Dimitry Morozov] has done just that with ‘conus’, which reads the surface of mollusk shells and translates the data into real-time audio and video. These shells are unique; their pigmentation generates natural cellular automata. (If you’ve never heard of cellular automata, Conway’s Game of Life is a good example, where a rule set determines whether a cell lives, dies, or regenerates.

[Dimitry's] installation uses homemade digital microscopes to scan the naturally-created cellular automata of several shells, each rotating on its own disc. As the shell spins, the scans from the microscopes are fed into an algorithm which transforms the signals into data for multiple audio channels and three video monitors. You can watch the mathematical translation of the biologically-formed patterns in a video after the break.

Check out the MSP430 game of life shield for another example of cellular automata.

Retrotechtacular: The history of ANSI and ASCII art

retrotechtacular-bsides-ansi-ascii-art-talkThese slides may not be the style of character art you remember from the days of 2400 baud modems; they’re more advanced than what was out there in the beginning. It turns out there is still some life left in this art subculture. For this week’s installment of Retrotechtacular we look in on [Doug Moore's] talk on the history and survival of ANSI and ASCII art given at this year’s BSides conference.

ASCII is still a common character encoding so chances are you’re already familiar with it. ANSI on the other hand is a rather confusing term as it’s been lost in obscurity when referring to character sets. In this case it refers to a set of extended characters which is better described as Windows Code Pages.

Most of what we know about the ANSI art scene is from watching BBS: The Documentary (which is on our ten best hacking videos list). We certainly remember seeing the vertically scrolling art after connecting to a dial-up BBS back in the day. But understanding the factions that formed around the creation, bundling, and distribution of this is art is fascinating. [Doug] does a great job of covering this history, sharing side-by-side examples of the shunned practice of “ripping” another artists work. This image is actually not a rip. Later in his talk he discusses the continued existence of the subculture, showing what a modern take on the same subject looks like.

If you’re merely into the technical the first half of the video below is worth watching. But we bet it’ll be hard not to continue to the end for a side-trip into art history.
