Move over Claude Monet, there is a new act in town in the form of a robot capable of creating some pretty cool art.
We’ve seen robotic artists before but most of them are either cartesian-based or hanging drawbots. This is a full-fledged Sharpie-wielding robotic arm that draws with dots giving its work an impressionistic feel.
The actual robotic arm is a stock Interbotix WidowX. The folks over at Phantom Multimedia wrote some custom software that takes a graphic and breaks it down into a 1-bit representation. The code then goes through the bitmap at random, picking points to draw on the medium. The hard part of this project was figuring out how to translate the 2D image into 3D robotic arm movements. Since the arm has several joints, there are multiple mathematical solutions for arm position to move the marker to any given point. The team ended up writing an algorithm to determine the most efficient way to move from point to point. Even so, each drawing takes hours.
As if that wasn’t enough, the software was then reworked to probe positions. Instead of automatically moving the arm to a predetermined point, the arm is manually moved to a location and the data retrieved from the servo encoders is used to determine the position of a probe at the end of the arm. Each point taken in this manner can then be combined to generate a 3D model.

If you’re walking around town and you see a light suddenly start to switch on and off seemingly at random, don’t discount it as a loose wire so quickly. [René] has been hard at work on a project to use city lights of all shapes and sizes for Morse messages, and a way for anyone to easily decode these messages if they happen upon one while out and about.
The lights can tell any story that is programmed into them. The code on the site is written for an Arduino-style microcontroller but it could be easily exported to any device that can switch power to turn a light on and off. Any light can work, there’s even video of a single headlight on a van blinking out some dots and dashes.
The other part of this project is a smartphone app that can decode the messages using the camera, although any Morse code interpreter can translate the messages, or if you’re a ham radio enthusiast you might recognize the messages without any tools whatsoever!
The great thing about this project is that it uses everyday objects to hide messages in plain sight, but where only some will be able to find them. This is indeed true hacker fashion! If you’re interested in making your own Morse code light, the code is available on the project site.
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.
[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.

Behind 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.

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.
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.

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.
