Biofeedback Flowers at Burning Man

Burning man, the premier desert-based convention, is a vacation for some. [Sam], on the other hand, points out that he is there to get his hands dirty. This year, he (with a team of six) built a set of 20 interactive lotus flowers that light up in sync with a heartbeat.

[Sam]’s biofeedback circuit is able to sense up to two heartbeats per flower. When a person’s heartbeat is detected, a set of high-power LEDs light up from the base of the stem upwards towards the petals for an incredible illuminated display of biofeedback.

The lotus flowers themselves aren’t anything to scoff at, either. They range from 8 to 18 feet high and are made out of steel and rowlux plastic. The circuit boards are all custom-made as well, with every part chosen to be as affordable as possible. The whole installation is powered by a deep-cycle marine battery and a set of 6V batteries, which can run all of the electronics in the flowers for the entire night before needing a recharge.

Burning man is a great example of art meeting technology. For other examples, check out this 2010 pyrotechnic ball, or head there yourself next August! Be sure to check out the videos and the project’s code on the project site as well.

The Tree of 40 Fruit

[Sam Van Aken] is working on a long-term project which literally will bear fruit. Forty different kinds, in fact. The Tree of 40 Fruit is a single tree, carefully grafted to produce 40 different varieties of fruit. Growing up on a farm, [Sam] was always fascinated by the grafting process – how one living plant could be attached to another.

In 2008, [Sam] was working as a successful artist and professor in New York when he learned a 200-year-old state-run orchard was about to be demolished. The stone fruit orchard was not only a grove a trees, but a living history of man’s breeding of fruit. Many unique varieties of stone fruit – such as heirloom peaches, plums, cherries, and apricots –  only existed in this orchard.

[Sam] bought the orchard and began to document the characteristics of the trees. Color, bloom date, and harvest date were all noted in [Sam’s] books. He then had the idea for a single tree which would bear multiple types of fruit. By using grafting techniques such as chip grafting, [Sam] was able to join the varieties of stone fruit tree. The process was very slow going. Grafts performed one year must survive through the winter before they grow the following spring.

Throughout the process, [Sam] kept careful diagrams of each graft. He planned the tree out so the fruit harvest wouldn’t be boring. Anyone who has a fruit tree tends to give away lots of fruit – because after a couple of weeks, they’re sick of eating one crop themselves! With [Sam’s] tree, It’s possible to have a nectarine with breakfast, a plum with lunch, and snack on almonds before dinner,  all from the same tree. The real beauty is in the spring. [Sam’s] tree blossoms into an amazing array of pinks, purples and whites. A living sculpture created by an artist with a bit of help from Mother Nature.

NYC Resistor Heats up the Big Apple with The 2014 Interactive Show

 

TitleNYCRBehind a nondescript loading dock in Brooklyn stands a normal looking brick building. Go up 3 narrow flights of stairs – you’ll find yourself at the door to the awesome known as NYC Resistor. Last Saturday, NYC Resistor held their 5th Interactive Show, and Hackaday was there! Much like the city it calls home, the Interactive Show is a melting pot. This particular pot is filled with NYC Resistor members (and the public) showing off their projects, NYU’s Tish School ITP students displaying their interactive art, and a good heaping portion of old fashioned hacker partying.

Art-O-Matic Is Spirograph’s Young Hip Offspring

Art-O-Matic automatic spirograph

Some of our more senior experienced readers may remember a toy called the Spirograph. In case you don’t, it’s a geometric shape drawing toy. The way it works is a plastic disc with gear teeth around the perimeter and various holes on its face is spun around a plastic ring with gear teeth on the inside. A pencil is inserted in one of the holes in the disc and, when spun around the inside of the ring, draws different complex shapes called hypotrochoids.

 Art-O-Matic automatic Spirograph

This was fun enough to keep a kid entertained for a few minutes. It took a while to make a complete shape and sometimes it was easy to mess up (especially if the hole chosen for the pencil was near the outside of the disc). [Darcy] thought it would be neat to combine the Spirograph’s drawing style with modern technology. The result is called the Art-O-Matic and it draws some pretty wild art, you guessed it, automatically.

Exploded Hardware Wall Art

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.
